# Choose Location

Good mobile signal quality is fundamental to getting a stable and fast internet connection over the mobile network. Please choose a location for the 5G router that has a fair 4G/5G signal reception.

### Mobile Networks Mode

There are various mobile networks, 2G, 3G, 4G, and 5G NR. Please take note of the signal bars and the symbol in the status bar of the mobile phone and compare them with the chart below.

<table><thead><tr><th width="150">Symbol</th><th width="314">Mobile Networks</th><th>Internet Speed</th></tr></thead><tbody><tr><td>5G NR</td><td>5G New Radio – Fifth generation mobile network</td><td>Up to 10 Gbps</td></tr><tr><td>4G LTE</td><td>Fourth generation or Long term evolution<br>also known as LTE or WiMax</td><td>Up to 1.6 Gbps</td></tr><tr><td>3G</td><td>Third Generation, known as UMTS WCDMA  CDMA2000</td><td>Up to 42 Mbps</td></tr><tr><td>2G</td><td>GPRS – General Packet Radio Service</td><td>Up to 64 Kbps</td></tr><tr><td>No Symbol</td><td>If signal bars get more than 1 bar<br>you can use voice call</td><td>No</td></tr></tbody></table>

### &#x20;Signal Strength

The chart below shows signal quality ranges for 4G/5G cellular networks. The main factors are RSRP and SINR. Ensure RSRP and SINR have a "Fair" signal level to maintain a stable mobile internet connection. Typically speaking, 3-5 bars indicate fair/good signals, and 1-2 bars indicate a poor signal that might sometimes lose connections. No bars mean no cellular signal was detected.

You can run a basic test on a mobile phone. Insert the SIM card into a mobile phone, disable Wi-Fi, and then walk around to check its network type and signal bars. Then, choose a location with strong and stable signal reception.&#x20;

| Quality   | RSRP (dBm)  | RSRQ (dB)  | SNR/SINR (dB) |
| --------- | ----------- | ---------- | ------------- |
| Excellent | > -80       | > -10      | > 20          |
| Good      | -80 to -90  | -10 to -15 | 13 to 20      |
| Poor      | -90 to -100 | -15 to -20 | 0 to 13       |
| Bad       | < -100      | < -20      | < 0           |

**Definition of Signal Strength**

**Excellent:** Maximum speed and data throughput.\
**Good:** Stable connection and good data throughput.\
**Poor:** Maintain data connection with restricted throughput.\
**Bad:** Connection drop or unable to keep a stable connection.

{% hint style="info" %}
The signal values are negative numbers. A number that is closer to zero means a stronger signal. For example, -90 dB is more robust than -100 dB.

1. Power off the router before inserting a SIM card.
2. Orient the Nano SIM card with the gold contacts facing up and the notched corner pointing inward. Then, align with Slot 1, which is the primary SIM slot the router will connect to. You can modify the connect SIMs later in the mobile interface settings.
3. Gently push the SIM card with your fingernail until you hear a slight click, confirming proper seating. Note that the SIM only fits in the direction mentioned above.

**To Remove a SIM Card** – Please turn off the power first and press the inserted SIM card with your fingernail until it clicks and springs out for easy removal.

<figure><img src="https://2305168564-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FqdMcm9X8duogQcX43EI2%2Fuploads%2FNFufSncSmtMAxBfhfJf2%2FEZR26-5G-Insert-SIM-Card.jpg?alt=media&amp;token=4cccaf77-0c1f-49b7-8813-a36361de18e6" alt=""><figcaption><p>Insert A SIM Card Align With SIM1 Slot</p></figcaption></figure>

{% hint style="warning" %}
Please always turn off the power while inserting or removing the SIM card.
{% endhint %}

{% hint style="info" %}

### Check and Clean the SIM Card

If Your Router Cannot Detect the SIM Card:&#x20;

First, confirm that the SIM card is already activated and has enough data allowance.&#x20;

Then, check if the SIM card is inserted in the correct orientation and fully seated in its slot. The golden contacts should face up, and the notched corner should point inward.&#x20;

After that, inspect the SIM card's gold contact points to ensure they are clean and damage-free. If you notice any dust or dirt on the gold contacts, gently clean them with a soft, dry cloth or eraser.
{% endhint %}


# Install Antennas

The EZR26-5G router uses MIMO antennas on both 5G and Wi-Fi connections.

Please check the chart and image below about which antenna goes to which socket.

| Antenna Sockets         | Antenna Marks |
| ----------------------- | ------------- |
| 4x Mobile (Side Panels) | 5G-NR Antenna |
| 3x Wi-Fi (Back Panel)   | Wi-Fi 6       |

The mobile antennas are wide paddle antennas with the printed mark "5G-NR Antenna." Their antenna sockets are on the left and right side panels, and they have "Mobile" marks.

The thinner Wi-Fi whip antennas have the printed "Wi-Fi 6" mark on the top end. The "Wi-Fi" antenna sockets are on the back panel.

To install the antennas, twist the connectors clockwise onto the router until they are securely fastened. Then, connect the antennas to the correct sockets, as shown in the image below.&#x20;

Only twist the connectors; do not excessively turn the antenna bodies, as this could damage the antenna pin or internal wiring. All the antennas have vertical polarization. Once installed on the router, ensure all antennas remain upright and vertical for the best possible reception and range.

<figure><img src="https://2305168564-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FqdMcm9X8duogQcX43EI2%2Fuploads%2F4nAmWWd4EG3MAaHEbbqZ%2FEZR26-5G-Install-Antennas-5G-WiFi_v1.2.jpg?alt=media&amp;token=5fc99448-1e11-45f9-a991-3acd24cabb68" alt=""><figcaption><p>Mobile 5G-NR Antenna and Wi-Fi 6 Antennas</p></figcaption></figure>

{% hint style="info" %}
The flat panels of the 5G paddle antennas have a higher performance. Please adjust the paddle direction towards the outside or signal source to receive a better signal.
{% endhint %}

{% hint style="warning" %}
To ensure optimal performance of your 5G router, position the device away from potential sources of radio frequency interference, such as microwave ovens, radio transmission equipment, and high-power electrical appliances.
{% endhint %}


# Power Supplies

The EZR26-5G router uses a 12Volt 2Amps DC power adapter.

## Power Up the Router <a href="#power-up" id="power-up"></a>

1. To ensure safe operation, use the original 12V/2A DC power adapter included with the 5G router.
2. Connect the power adapter to any standard 100-240V electrical AC outlet, then plug the DC jack into the router's DC power socket on the back panel.
3. The router will automatically power on when connected, with front panel LED indicators showing its operational status.

<figure><img src="https://2305168564-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FqdMcm9X8duogQcX43EI2%2Fuploads%2FpBJAE7YEAacFGmcHDwnW%2F5G-Router-Power-Adapter-AC-Plugs.jpg?alt=media&amp;token=cc3e28b4-c9f2-4eed-a825-2a5bdf250fe8" alt=""><figcaption><p>AC-DC Power Adapter for 5G Router</p></figcaption></figure>

### Alternative Power

If you need to power the router with other power sources, ensure they provide stabilized 12Volt 2Amps DC power and include overvoltage and short circuit protections on the appropriate DC jack, Ø5.5 x 10mm with a Ø2.1mm inner pin.&#x20;

Higher voltages and currents can damage the router, and insufficient voltages and currents might not be able to power up the router or reduce the operating performance.

* **RSRP, RSRQ, and SINR** are the [signal quality parameters](/manual/installation/choose-location#signal-strength). Their background color indicates the estimated quality level: green represents excellent, yellow means fair, and red represents poor.

### ii. Troubleshooting

Below are the common issues that may occur during daily use and their related solutions. Please refer to the [**modem diagnosis**](https://how.router.works/mobile/dx) for detailed instructions on running modem diagnostics and troubleshooting.

<details>

<summary>No SIM Card Detected</summary>

**Appearance:** If the SIM status shows "No SIM" and the modem cannot connect, the SIM card might be inserted incorrectly or blocked by the mobile carrier.

**Solution:** First, test the SIM card on a smartphone to ensure it is functional. If it's a brand-new SIM card, follow the mobile carrier's instructions to activate it.&#x20;

Then, follow the [SIM card operating instructions](/manual/installation/insert-sim-card) to reinsert the SIM card. Remember to check the golden contacts on the SIM card and clean any dirt before reinserting.

</details>

<details>

<summary>Failed To Connect</summary>

**Appearance:** If the SIM card is detected but the modem status shows "Not Connected," the signal may be too weak, or the SIM card may have run out of data allowance.&#x20;

**Solution:** First, check the [signal quality](/manual/installation/choose-location#signal-strength) and ensure the RSRP value is above -105dBm. Then check your SIM card account and ensure it has enough data allowance.

After that, verify the mobile [APN settings](#apn-settings). If you are still unsuccessful, refer to the below [mobile protocol](#mobile-protocols) guidance to switch to the traditional protocol. Some low-priority data plans may be restricted from connecting through the advanced protocol.

</details>

<details>

<summary>Connected But No Internet</summary>

**Appearance:** This issue led to being unable to access the internet, indicating that the SIM status is connected. The mobile interface has obtained an IPv4/6 address, and the Mobile status displays signal quality.

**Solution:** First, test the SIM card on a smartphone to ensure it is functional. If it's a brand-new SIM card, follow the mobile carrier's instructions to activate it.&#x20;

Then, check that it has enough data allowance. After that, verify the [APN address](#apn-settings) with the carrier and modify it as the guide below shows. Finally, recheck the RSRP value for signal quality and ensure it's above -105dBm.

</details>

<details>

<summary>Connected But Unstable</summary>

**Appearance:** If the modem status is connected but suffering from slow internet speed or intermittently interrupted connections, these issues are usually caused by busy hours, unstable mobile signals, and frequent remote access requests.&#x20;

**Solution:** When too many terminals connect to the same cell tower during busy hours, the average mobile speed slows down and may be interrupted. Consider improving the signal quality by changing locations or upgrading the SIM card's data to a business grade, which typically offers an uninterrupted priority connection from mobile carriers.

To maintain a fast and stable mobile connection, the recommended RSRP value should be above -100 dBm. To enhance mobile signals, consider adjusting the location or upgrading the antennas.

If the mobile connection obtains a public IP address, it may receive frequent remote access requests that could disrupt local networks. Go to "Status > System Log" to download the router's system log and send it to our support team for an optimization plan.

</details>

***

## APN Settings <a href="#apn-settings" id="apn-settings"></a>

APN, the mobile network gateway, stands for Access Point Name. Generally speaking, the EZR26-5G router can establish a mobile connection using the prebuilt parameters for many carrier SIM cards.

Some carriers and specific data plans require a dedicated APN address to connect. Please check the correct APN address with your SIM card provider, then follow the guide below to configure the APN parameters.

**To modify APN settings**

Then, input the below corresponding APN settings provided by your mobile carrier:

* Protocol – Keep it as "Modem Manager" unless a traditional PPP or QMI protocol is needed.
* Bring Up On Boot – Keep this checkbox selected to start the mobile connection at every startup.
* **APN** – Input your SIM card's APN gateway address.
* **PIN** – Your custom PIN code to protect the SIM card. Leave it empty if the SIM is on default PIN.
* **Authentication Type** – Use PAP, CHAP, or both PAP/CHAP. Usually deploy PAP.
* **IP Type** – Usually use IPv4 only or leave it as IPv4/IPv6 both.
* Signal Refresh Rate – The interval for scanning and detecting signal quality, which is displayed on the dashboard and modem status. Setting it to more than 10 seconds to avoid interruption.<br>

Click the green **"Apply"** button to save and apply the custom settings to the primary SIM1 slot. Repeat the same operation for the secondary SIM2 slot if it has a SIM card.&#x20;

Finally, click the green **"Save"** button in the bottom right corner to make the changes effective. Wait 5-10 seconds for the parameters to be applied, then refresh to check the new status.

Learn more about general APN settings and [generic global APN parameters](https://www.outdoorrouter.com/news/apn-settings-for-outdoor-4g-router/). The best option is to contact your SIM card provider for the accurate APN address assigned to your data plan.

{% endembed %}

### iv. Terms

**WiFi Mode –** Includes master access point and relay client.&#x20;

* The **master hotspot** is created by the router itself as its main wireless network to broadcast for Wi-Fi enabled devices. The devices connected to the master hotspot will obtain IP addresses from the router's DHCP server and be controlled through the router's security firewall and QoS rules.&#x20;
* In contrast, the **Wi-Fi client** is established by a Wi-Fi relay link that connects to an existing Wi-Fi network and obtains an IP address from the upstream router's DHCP server. It can extend wireless network coverage and relay data between connected devices and the upstream router.

**WiFi Hotspot Name** of SSID / ESSID / BSSID

* SSID, also called WiFi hotspot name. ESSID is short for Extended Service Set Identifier. ESSID is a textual name and it is typically regarded as the SSID.
* BSSID is the MAC address of the Wi-Fi radio node used for management and maintenance.

# Recovery

Fix the issues on the Internet and wireless networks and rescue the router from misconfigurations.

## Reboot Router

The 5G router has a Linux-based operating system, like a baby computer. Rebooting the router can solve mysterious glitches, fix Internet connectivity issues, and improve security.

The mobile carrier assigns a temporary IP address for every mobile connection. If the modem misses the timeout for IP release, the Internet connection may become slow or interrupted. In these cases, rebooting the router could find channels with less traffic and increased speeds.&#x20;

### i. Soft Reboot

After logging into the router, navigate to "System > Reboot" and tap the "Perform reboot" button to initiate a soft reboot.

### ii. Hard Reboot

The router has a memory chip to store caches and temporary files. To completely clean them, we need to perform a hard reboot by unplugging the power adapter. Then, wait for more than 3 seconds before reconnecting.

{% hint style="danger" %}
Do not disconnect the power supply while **flashing** firmware and **resetting** the router, as this may result in critical firmware system failure.

# Internet & IP

Run a first quick Internet access test to check Internet connectivity.

## Internet Connection

You can quickly check the mobile connection on the "Modem" and "Internet" sections on the front dashboard.

* After successfully setting up an Internet connection on the mobile modem:

  * The "Mobile" section displays "Connected" on the status field.
  * The "Internet" section shows IPv4 and gateway obtained from the mobile carrier.

  \
  *or*<br>
* Navigate to "Network > Interfaces" and find the first row of the "Mobile" interface to view the IP address, RX TX stream, and connection uptime.

  \
  *or*<br>
* Go to "Network > Diagnostics" and use the "IPv4 Ping" tool to check your internet connectivity. When the mobile signal is fair/strong, and there is no internet interruption, the ping tool should return "0% packet loss."

## IP Address

The "Internet" section on the front dashboard and the "Mobile" interface under "Network > Interfaces" display the IPv4/6, DNS, and gateway of the mobile internet connection.

**Public and Private IP Address**

The mobile carrier typically assigns a private IP address for the mobile connection. A private IP does not traverse the Internet and cannot be used for remote access. Check out the [IP and DNS](https://how.router.works/net/traffic/ip-dns) tutorials.

Below are the standard formats of private IP addresses:

* 10.0.0.0 to 10.255.255.255
* 172.16.0.0 to 172.31.255.255
* 192.168.0.0 to 192.168.255.255
* 100.64.0.0 to 100.127.255.255 (Carrier-Grade)


# Firewall Settings

The router firewall controls the forward packet streams from incoming network interfaces to outgoing network interfaces. It adds another layer of granularity to what can be forwarded across interfaces and which packets can be inputted and outputted.

## Firewall Zones

The firewall collects interfaces into zones to filter traffic logically. A zone can be configured to any set of interfaces. This simplifies the firewall rule logic somewhat by conceptually grouping the interfaces:

* A rule for a packet originating in a zone must enter the router on one of the zone's interfaces,
* A rule for a packet being forwarded to a zone must exit the router on one of the zone's interfaces.

To configure the firewall zones, go to "Network > Firewall" after accessing the router. The prime tab of "General Settings" allows the modification of the firewall zones. You can use the default firewall zone settings as shown below in most conditions.

<figure><img src="https://2305168564-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FqdMcm9X8duogQcX43EI2%2Fuploads%2FhePxMly6szuubhq7xWse%2FFirewall-Zones-on-Cellular-Router.jpg?alt=media&amp;token=da5dda7f-3837-4219-aa26-79159a70c999" alt=""><figcaption><p>Default Firewall Zone Settings on Cellular Router</p></figcaption></figure>

### ii. Port Forward (WAN) <a href="#ii-port-forwards-wan" id="ii-port-forwards-wan"></a>

Click the second tab labeled "Port Forwards" to configure port forwarding rules. You can refer to the preset port forward rules. Below is the step-by-step guidance for setting a new port forward rule.

1. Name – Enter your custom reference name. e.g., Test
2. Protocol – Select from TCP, UDP, or both.\
   *Note: If you don't know the exact protocol, choose TCP+UDP. Please select TCP or UDP if you know whether it is TCP or UDP. It can effectively reduce resource consumption.*
3. External Port – Set the port number you want to access from the external network \
   *Note: Suggest selecting the WAN port between 1025\~25534. Do not use the standard ports occupied by the other services such as 23, 80, 433, 3389, 7700, 10080, etc.*
4. Destination Zone – Select LAN
5. Internal IP Address – Select from the list of connected intranet hosts.\
   *If you can not find the host on the list, please recheck the IP settings on the host.*
6. Internal Port – Choose the port number that needs to be forwarded from the intranet host
7. Click the "Save" button and then the "Save & Apply" button on the firewall page to execute the new settings.

**Advanced Settings > NAT Loopback**

NAT Loopback is turned on as the default setting. It allows intranet terminals to access local hosts using the public IP address of the routed external network interface. If you need to reduce the consumption of router resources, you can disable this function.

​

### iii. Local Forwards <a href="#iii-intranet-forwards" id="iii-intranet-forwards"></a>

The 5G router supports access to another connected host through the router's IP address and port number. You can set up intranet local forwarding using iptables.&#x20;

To configure local forwarding, go to the last "Custom Rules" tab to add new iptable rules. Below are example codes to forward 192.168.20.113:80 to the router's IP 192.168.20.1:1138.

<details>

<summary>Example Scripts</summary>

## Dynamic DNS

When a 5G router is assigned a public IP address via Mobile, WAN, or WiFi relay internet sources, Dynamic DNS enables easy remote access to the router.

Dynamic DNS links a static hostname to the router's public IP address, updating it automatically when the IP address changes. For more details, see the [Dynamic DNS](https://how.router.works/remote/dynamic-dns) tutorial.


# Command Sets

The command-line interface (CLI) is a way of interacting with the router system. In this mode, the user issues commands to the router system through command lines.

Secure Shell (SSH) is a cryptographic network protocol that allows access to the router’s command-line interface. The 5G router offers various ways to access the command-line interface.

## **SSH Terminal** <a href="#web-terminal" id="web-terminal"></a>

The 5G router offers the most straightforward web terminal interface for browser access. Once you connect to the router, navigate to "Services > Terminal." Alternatively, you can access SSH software on your computer via the SSH port. Click the [SSH Terminal](https://how.router.works/dev/ssh) tutorial for more details.

# Troubleshootings

The collection of the common issues and quick guidance.

## Changing Password

**i. Wi-Fi Password**

The default Wi-Fi network is active and does not have an encryption password. To secure your wireless networks, refer to the [Wi-Fi SSID & Password](/manual/firmware/wifi-hotspots#wifi-settings) section for guidance on configuring the encryption type and password.

**ii. Router Password**

The router admin panel is initially without a password. Once you've accessed it, navigate to "System > Administration" to create your custom [router password](/manual/firmware/system-admin#router-password).

***

## Forget Router Password

After updating the router password, make sure to store it safely. If you forget the router password, the only option is to perform a [Hard Reset](https://indoor.router.works/manual/pages/ZOx9Ekkf7GsrOn6E7KHJ#ii.-hard-reboot) to regain access, which will remove all previous custom settings.

***

## Disable Wi-Fi Network

To turn off the Wi-Fi hotspot or Wi-Fi relay links, access the router and navigate to "Hotspot > WiFi Hotspot" to visit the "Wireless Overview" page. Then, click the "Disable" button next to the relevant Wi-Fi SSIDs. Check more on the [Wi-Fi hotspot](/manual/firmware/wifi-hotspots#wireless-overview) guidance.

***

## No Wi-Fi Hotspot

If you cannot locate the router's hotspot on Wi-Fi enabled devices, please review the indicators on the router's front panel below.

1. **System Indicator**<br>
   * If both "Power" and "System" indicators are **off**, check the connections of the power adapter and electric outlet, then try to reconnect the power adapter.
   * If the "System" indicator is flashing, please wait 2-3 minutes until the router boots up.<br>
2. **Wi-Fi Indicator** - When the system indicator stays solid white, check the Wi-Fi indicator.<br>
   * If the Wi-Fi indicator stays solid, 2.4G and 5.8G Wi-Fi hotspots have been enabled.
     * You can try to search for the Wi-Fi hotspot. Remember, you might have changed the Wi-Fi SSID name once before.
     * If you enabled the "Hide ESSID" checkbox, please manually input the device's Wi-Fi SSID name and password.<br>
   * If the Wi-Fi indicator is off, one or both Wi-Fi hotspots might be disabled on the firmware. Access the router with the LAN cable connection and enable the Wi-Fi network. If the LAN cable connection still does not work, [reset the router](https://indoor.router.works/manual/pages/ZOx9Ekkf7GsrOn6E7KHJ#ii.-hard-reboot) to default settings.

***

## Reset the Router

You can use either a soft reset or hard reset to erase the configurations on the router and go back to the factory settings. ‌The suggested way is a [**soft reset**](https://indoor.router.works/manual/pages/ZOx9Ekkf7GsrOn6E7KHJ#i.-soft-factory-reset). If unable to access the router, please do a [**hard reset**](https://indoor.router.works/manual/pages/ZOx9Ekkf7GsrOn6E7KHJ#ii.-hard-reset) by clicking the reset button for 5 seconds when the router is turned on.

‌ If the hard reset does not work, please refer to the [Bootloader](/manual/advanced/bootloader) tutorial to rebuild the firmware system.

## Insert SIM Cards <a href="#insert-sim-cards" id="insert-sim-cards"></a>

Step-by-Step

1. Turn off the power before inserting SIM cards.
2. Use the included SIM pin to push the pinhole gently until the SIM card holder pops out.
3. Put the primary SIM card in the first slot. Make sure notch in the inside direction and pins face down. There is only one correct way to settle the Nano SIM card into the SIM card holder.
4. Carefully reposition the SIM card holder in the slot and push it back gently.

<figure><img src="https://299607912-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FXrJBTozkgaqqeDtauCDH%2Fuploads%2FyF3MoqqbanHbzFu98UQU%2FEZR24-Cat12-4G-Router-SIM-Card-Slot_v1.2.jpg?alt=media&#x26;token=74eba0c8-a73c-4288-a001-a5cb03975757" alt=""><figcaption><p>4G Router with SIM Card Slot</p></figcaption></figure>


# Power Supplies

The 4G indoor router uses a 12Volt DC power adapter. Please ensure to use the correct voltage and current if using other power sources.

An AC to DC power adapter is included in the package.&#x20;

Connecting the DC power adapter to the 100\~240 Volt AC electrical outlet power, it outputs 12Volt 2Amps DC power to the 4G router.

{% hint style="info" %}
‌You could exchange the plug if you received more than one power plug. Press the "Push" button and twist the power plug clockwise to remove it.&#x20;

Then, install another plug on the power adapter and twist it in the anti-clockwise direction to tighten it.
{% endhint %}

<figure><img src="https://758914960-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LvFmeL2Pv0EF2-7nON9%2F-M51RafeYBQXwOdRQkHZ%2F-M51XDrGGaTYq-2uyz9w%2FEZR23-4G-Router_DC-Power-Adapter.jpg?alt=media&#x26;token=0518aa88-58f2-45d1-a4a2-86c6b8978617" alt=""><figcaption></figcaption></figure>

## Alternative DC Power

The DC power socket on the 4G router can work with 12Volt and 2Amps DC power. The correct DC jack is Ø5.5 x 10mm, and the inner pin is Ø2.1mm.


# Install Antennas

The 4G router uses MIMO antennas on both mobile and Wi-Fi connections.

When installing the antennas, set the router and antennas in a straight direction to avoid bending the pins in the connector.

Please check the below chart about which antenna goes to which socket.

Twist the SMA-male connector on the antennas in the clockwise direction to install the antennas on the router. Make sure the connection is tight.

<table><thead><tr><th width="201">Antenna Socket</th><th>Antenna Marks</th></tr></thead><tbody><tr><td>Mobile 1 *Main</td><td>Either 4G paddle antenna</td></tr><tr><td>Mobile 2</td><td>Either 4G paddle antenna</td></tr><tr><td>WiFi 4</td><td>Either WiFi4 whip antenna</td></tr><tr><td>WiFi 5</td><td>Either WiFi5 whip antenna</td></tr></tbody></table>

{% hint style="info" %}
The two flat panels of the 4G paddle antennas have a higher performance. Please adjust the paddle direction to the outside or signal source to receive a better signal.
{% endhint %}

<figure><img src="https://299607912-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FXrJBTozkgaqqeDtauCDH%2Fuploads%2FC1JkEOWhReiw2514rHuo%2FEZR24-4G-Router_Install-Antennas.jpg?alt=media&#x26;token=a5565661-6ad0-45aa-aca4-52e55881ed44" alt=""><figcaption></figcaption></figure>

### Upgrade Antenna

When you have a weak signal reception, please consider upgrading the 4G mobile antenna with a higher-gain antenna. The outdoor directional antennas could point toward the cell tower and receive more robust signals.

To connect to the other mobile or WiFi antennas, make sure these antennas have the standard SMA-male connectors. You can use a MIMO antenna or a single-polarized antenna on the router. The single-polarized antenna should connect to the mobile main socket on the left side.&#x20;

# Mobile Protocols

There are two different mobile protocols built-in the 4G 4 router. The default mobile protocol is Mobile Data. Suggest using the default protocol unless your mobile provider does not support it.

### **Mobile Data Protocol**

The **Mobile Data** protocol is based on **QMI**, *Qualcomm MSM Interface*, a proprietary protocol offering more accessible and faster connections to mobile networks.

Due to the difference in the modem chipsets, the different mobile modems might use other QMI proxies. For example, Sierra modems use the *QMI\_WWAN proxy,* and Quectel modems use the *GobiNet proxy*. These proxies use the same QMI protocol and provide similar working performance.

The primary difference is that *GobiNet* uses kernel space, while *qmi\_wwan* uses user space. And in *qmi\_wwan*, only one process can handle the control port at a given time, while the *GobiNet proxy* allows multiple processes to access the device concurrently.

### **4G-PPP Protocol**

**PPP**, *Point-to-Point Protocol*, is a traditional data link layer communications protocol. PPP protocol has been very widely used and is most flexible for interoperability with devices.

Some mobile carriers might not support QMI protocol to connect to their mobile networks. We must change the mobile protocol from the default *Mobile Data* protocol to the *4G-PPP* protocol.

### Switch to PPP Protocol

Under `Common Configuration` > `General Setup` of the Mobile interface, choose `4G-PPP` on the dropdown menu of `Protocol`. Then click the confirm button `Switch protocol`. It will jump to the 4G-PPP protocol setup page.

Comparing with the `Mobile Data` protocol, the `4G-PPP` protocol has two extra configuration fields, `Service type` and `Dial number`. The other parameters, including APN / PIN / Username / Password, are the same configuration operations as the QMI cellular protocol.

* `Mobile device`: Choose `/dev/ttyUSB2`
* `Service type`: Due to differences in mobile network standards, choose the services below:
  * `UMTS/GRPS` for the UK / European / Australian versions
  * `CDMA/EV-DO` for the American versions
* `Dial number`: Use `*99#` for European standard network, and use `*99***1#` for American standard networks.

Click `Save & Apply` button on the bottom right corner to apply the new APN parameters. Then back to `Network` > `Interfaces`Wait 1-2 minutes until the mobile modem reconnects to the mobile network.&#x20;

<figure><img src="https://299607912-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FXrJBTozkgaqqeDtauCDH%2Fuploads%2FgcLVCzJ1iGVVx0R5kGrL%2F4G-Router-Firmware-Switch-to-PPP-Protocol.jpg?alt=media&#x26;token=1c5a83d4-2911-4770-8661-65dbcd94f1dc" alt=""><figcaption></figcaption></figure>

{% hint style="info" %}
Select "Mobile Data" from the protocol field and click the "Switch Protocol" button to switch the protocol back to Mobile Data. Then, configure the parameters as shown on the default [mobile modem settings](/ezr24/manual/firmware/mobile-modem#apn-settings).
{% endhint %}


# Mobile Band Lock

In some rare conditions, such as between two cell towers, we need to lock the 4G router to work on a specific band to get a stable connection or faster speed.

### Supported Mobile Bands

The CAT12 mobile modem on the EZR24-012 router supports the below bands.&#x20;

Before locking the band, please ensure the bands you want to use have at least a "Fair" signal reception in your area. Please refer to the [signal test tutorial](https://www.outdoorrouter.com/field-test-4g-mobile-signal-strength/) to check the signal strength.

<table><thead><tr><th width="328.3641570031964">4G FDD-LTE</th><th width="196.66133863872392">4G TDD-LTE</th><th>3G</th></tr></thead><tbody><tr><td>Band 1/2/3/4/5/7/8/9/12/13/14/17/18/19/20/21/25/26/28/29/30/32/66</td><td>Band 38/39/40/41</td><td>Band 1/2/3/4/5/8/9/19</td></tr></tbody></table>

### Lock Modes & Bands

The EZR24 firmware has integrated a web interface to easily lock network modes and mobile bands.

After accessing the router's admin page, go to "Network > Interfaces > Mobile: Edit." Click the tab  "Advanced Settings."

**Supported Modes** are 3G and 4G. I suggest enabling both of them.\
**Preferred Mode**: Select 3G or 4G on this field.\
**Support Bands:** Pick up the 3G and 4G bands by enabling the checkbox.\
**Signal Refresh Rate:** Suggest inputting "10\~30" seconds.

**UTRAN** is the Radio Access Network Architecture of 3G UMTS, while **EUTRAN** is that of the LTE.

Click the "**Save & Apply**" button on the bottom right corner to take effect of the above settings.

Wait 2\~4 minutes until the mobile interface connects to the cellular network. If it has failed to connect to the mobile network, suggest reviewing the signal reception of the selected bands in your area.

# Recovery

Fix the issues on the Internet and wireless networks and rescue the router from misconfigurations.

## Reboot Router

Like a regular computer, the 4G router has a Linux-based operating system. Rebooting the router can solve mysterious problems, fix Internet connectivity issues, and improve security.

The Internet provider assigns a temporary IP address, which can be changed during a timeout. If the router misses the change, the Internet connection might become slow. The same can happen if too many devices are connected to the router. For example, the routers found channels with less traffic and increased performance speeds while rebooting.&#x20;

### i. Soft Reboot

After accessing the router, go to `System` / `Reboot`, you can perform a **soft reboot**.

### ii. Hard Reboot

To do a **hard reboot**, please unplug the PoE adapter, wait a few seconds, and then connect it again.

# Internet & IP

Run a first quick Internet access test to check Internet connectivity.

## Internet Connection

You can quickly check the mobile connection on the `Device information` section on the front page or go to `Status` > `Overview`.&#x20;

* After successfully setting up an Internet connection on the mobile modem:

  * The `Mobile Connection` field on the column of `Device` information will shows `Connected`.
  * The `Network` section will show the current mobile network gateway in the table of`IPv4 Upstream`.

  \
  *or*<br>
* Go to `Network` > `Interfaces`, the `Mobile` interface will show `Rx/Tx` rates.&#x20;

  * The `Mobile_4`interface shows the `IPv4` IP address. *\*For `QMI protocol` only.*

  \
  *or*<br>
* Go to `Network` > `Diagnostics`
  * Click on the `Ping` button or use the command `ping outdoorrouter.com` on the `Command-line` .
  * it should return `0% packet loss` if everything is alright with the Internet connection.

## IP Address

Go to `Network` > `Interfaces`. On the rows of `Mobile` or `Mobile_4`, you can find the IPv4 IP address obtained by the mobile modem.

### Public IP Address

The mobile carrier usually provides a LAN IP address for the mobile connection.&#x20;

To verify the public IP address, you can first check the above IPv4 IP address obtained by the mobile modem. Then, search *My IP* on *Google* and compare the returned public IP address with the IPv4 mobile IP address.&#x20;

If they are different, it means your router uses a LAN IP address from the carrier.

{% hint style="info" %}
If you have the public IP address and are required to access the router remotely at the public IP address, please refer to the [Changing Web Port](/ezr24/manual/advanced/internet-and-ip/changing-web-port).
{% endhint %}


# Changing Web Port

Guidance of how to change the Web GUI interface port on the 4G router.

The internet operators usually block 80 ports, which are used by the web interface of the 4G router. To access the 4G router remotely on the public IP address, we need to change the port for the web interface.

When the router is turned on, access the command-line interface. Input the below command `vi /etc/lighttpd/lighttpd.conf`. Now, we are in the *command mode* of the VI editor.

* Press i on the keyboard to enter the *insert mode*.
* Scroll down to line No.89. The original code is `#server.port = 81`.
* Delete `#` and change the server port to `880`, for example.
* Press *ESC* on the keyboard. Exit from the *insert mode* to the *command mode*.
* Press `: wq` on the keyboard to save the file and exit to the SSH terminal.

Input the below command to restart Lighttpd. `server /etc/init.d/lighttpd restart`.

```
######### Options that are good to be but not necessary to be changed #######

## bind to port (default: 80)
server.port = 880
```

Now, we should re-login the router admin at `http://192.168.20.1:`**`880`**. If your router has a public IP address, you can access the router at `public-ip-address:880`.

*\*Besides using the VI editor, you can also use an **SFTP** client software, like **WinSCP**, to edit the `lighttpd.conf` file.*


# Firewall Settings

The router firewall controls the forward packet streams from incoming network interfaces to outgoing network interfaces.

Firewall rules add another layer of granularity to what is allowed to be forwarded across interfaces and which packets are allowed to be inputted and outputted.

## Firewall Zones

The firewall can collect interfaces into zones to filter traffic logically. A zone can be configured to any set of interfaces. This simplifies the firewall rule logic somewhat by conceptually grouping the interfaces:

* A rule for a packet originating in a zone must enter the router on one of the zone's interfaces,
* A rule for a packet being forwarded to a zone must be exiting the router on one of the zone's interfaces.

After accessing the router, go to `Network` > `Firewall` to enter the `Firewall - Zone Settings`.The `SYN-flood protection` is enabled by default. You can use the default firewall zone settings below in most conditions.

<figure><img src="https://758914960-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LvFmeL2Pv0EF2-7nON9%2F-LxZyv7tzLU4F4jop0jB%2F-LxZz9MrAVtqrSRJv0k4%2Fimage.png?alt=media&#x26;token=9673f210-91f5-4f3b-a4cb-55f2bd4a7c49" alt=""><figcaption><p>Default firewall zone settings</p></figcaption></figure>

## Port Forwards <a href="#port-forwards" id="port-forwards"></a>

Port forwarding is an application of network address translation (NAT) that redirects a communication request from one address and port number combination to another. Port Forwarding allows remote computers to connect the outdoor router within a private local-area network (LAN).

### i. General Settings <a href="#i-general-settings" id="i-general-settings"></a>

Log in to the router, go to `Network` > `Firewall`. \
➀ Under the tab of `General Settings`, change forward to `accept`. \
➁ In the **Zones** section, change the **Forward** on the row of **WAN** from `reject` to `accept`. \
Click the **Save & Apply** button on the bottom right corner.

<figure><img src="https://758914960-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LvFmeL2Pv0EF2-7nON9%2F-MAvUwpP9uQPquAbNyY3%2F-MAvVQO0M7JyKjsTjBm_%2Fimage.png?alt=media&#x26;token=c44784c9-41e8-4ede-9e25-f13a669aff4b" alt=""><figcaption></figcaption></figure>

### ii. Port Forwards (WAN) <a href="#ii-port-forwards-wan" id="ii-port-forwards-wan"></a>

Click the tab `Port Forwards` to enter the configure section on the **New port forward** section:

1. `Name` : Enter the reference name. e.g., *`Test`*
2. `Protocol`: Select from `TCP`, `UDP`, and `TCP+UDP`

   📌 *If you don't know the protocol, please choose TCP+UDP. Please select TCP or UDP if you are aware of whether it is TCP or UDP. It can effectively reduce resource consumption.*
3. `External zone` : Select `WAN`
4. `External port` : Set the port number you want to access from the external network \
   📌 *Suggest selecting the WAN port between 1025\~25534. Do not use the standard ports occupied by the other services such as 23, 80, 433, 3389, 7700, 10080, etc.*
5. `Internal zone` : Select `LAN`
6. `Internal IP Address` Select from the list of connected intranet hosts \
   📌 *If you can not find the host on the list, please recheck the IP settings on the host.*
7. `Internal port` : Choose the port number that needs to be forwarded from the intranet host
8. Click the button `Save & Apply`

The below example was forwarded to localhost *192.168.30.113:80* to WAN port *1180*. You can access the *80* port on the host of *192.168.30.113* from the public IP address plus port *1180*. It's NOT accessible from the router's local IP, e.g. *192.168.30.1:1180*.

<figure><img src="https://758914960-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LvFmeL2Pv0EF2-7nON9%2F-MAvUwpP9uQPquAbNyY3%2F-MAvVbryHoe0XevYYz94%2Fimage.png?alt=media&#x26;token=88198e7a-c091-4e2d-b929-e1cc22c9403b" alt=""><figcaption></figcaption></figure>

**NAT Loopback** is turned on after saving a new port forward rule. It allows the intranet terminal to access the local hosts using the public IP address of the routed external network interface. To reduce the consumption of router resources, you can click the **Edit** button on the saved port forward rule list to disable it.

### iii. Intranet Forwards <a href="#iii-intranet-forwards" id="iii-intranet-forwards"></a>

To access another host from the router IP address, we can set up intranet forwarding based on `iptables`. Go to the tab `Custom Rules`, add the new iptable rules. Below are the example codes to forward 192.168.30.113:80 to router IP 192.168.30.1:1180.

`iptables -t nat -A PREROUTING -d 192.168.30.1 -p tcp --dport 1180 -j DNAT --to-destination 192.168.30.113:80 iptables -t nat -A POSTROUTING -d 192.168.30.113 -p tcp --dport 80 -j SNAT --to 192.168.30.1`

# Bootloader

Rescue the 4G router from the "brick" mode.

The router will be stuck in the reboot cycle when the firmware is incomplete or broken. The router keeps rebooting, and WiFi & LAN cannot hold for over 3 minutes.

It usually happens because of deleting critical files or disconnecting from the power supply while resetting or flashing firmware. The EZEN4X series, including the 4G router, has a built-in uBoot bootloader to re-build the firmware system.

### Static LAN Connection

Connect a computer to the LAN port on the router. Then, configure the static IP address below on the computer.&#x20;

Computer IP: 192.168.1.150 \
Router IP: 192.168.1.1 \
Subnet mask: 255.255.255.0 (also called 24 on Windows OS)

Router IP: 192.168.20.1 \
Subnet mask: 255.255.255.0

Do not turn off power while flashing the firmware!


# Troubleshooting

The collection of the problem elimination process.

## Changing Password

**i. Wi-Fi Password**

The default Wi-Fi network is turned on and without the encryption password. You can refer to Wi-Fi SSID & Password to configure the encryption type and password to secure your wireless networks.

**ii. Router Password**

The default router password is `root` or `admin`. After accessing the router at **`http://192.168.20.1`**, go to `System` > `Administration`, you can change the router administration password.&#x20;

*\*The default router username is `root`.*

## Forget Router Password

The default login password is `root` or `admin`. If you have changed the router password and forgotten it, please reset the router to default settings. It will erase the previous configurations, and you can log in to the router again with the above default password.

## Wi-Fi SSID and Password

The Wi-Fi network is turned on by default. The default Wi-Fi SSID is `Cellular-WiFi-xxxxxx`. It's without the encryption password. You can refer to Wi-Fi SSID & Password to configure the encryption type and password to secure your wireless networks.

## Disable Wi-Fi Network

To disable the Wi-Fi network, please access the router at `http://192.168.20.1`, go to `Network` > `Wireless`. You will enter the `Wireless Overview` page.

‌ There is only one radio section of `radio0`. The Wi-Fi hotspot created by the router is in the `mode` of **`Master.`** You can click the **`Disable`** button to turn off the Wi-Fi hotspot.

*\*If the Wi-Fi network is in the `mode` of `Client`, the Wi-Fi network is for the Wi-Fi relay connections.*

## Can Not Find Wi-Fi Hotspot

Please open the case of the 4G router and check the below indicators on the 4G router.

1. **System Indicator**<br>
   * If the system indicator is off, please check the connections of the power adapter and electric outlet.
   * If the system indicator is flashing, please wait 2-3 minutes until the router boots up.<br>

2. **Wi-Fi Indicator** - When the system indicator stays green, check the Wi-Fi indicator.<br>

   * If the Wi-Fi indicator stays green, the Wi-Fi network has been enabled, but no data is streaming on the Wi-Fi network.&#x20;
     * You can try to search for the Wi-Fi hotspot. Remember, you might have changed the Wi-Fi SSID name once before.
     * If you enabled the checkbox `Hide ESSID`, please manually input the device's Wi-Fi SSID name and password.<br>
   * If the Wi-Fi indicator is off, the Wi-Fi network has been disabled. Please access the router with the LAN cable connection and enable the Wi-Fi network.

# Choose Location

Good mobile signal quality is fundamental to getting a stable and fast internet connection over the mobile network. Please choose a location for the 5G router that has a fair 4G/5G signal reception.

### Mobile Networks Mode

There are various mobile networks, 2G, 3G, 4G, and 5G NR. Please take note of the signal bars and the symbol in the status bar of the mobile phone and compare them with the chart below.

<table><thead><tr><th width="150">Symbol</th><th width="314">Mobile Networks</th><th>Internet Speed</th></tr></thead><tbody><tr><td>5G NR</td><td>Fifth generation mobile network</td><td>Up to 10 Gbps</td></tr><tr><td>4G (LTE)</td><td>Fourth generation or Long term evolution<br>also known as LTE or WiMax</td><td>Up to 1 Gbps</td></tr><tr><td>3G</td><td>Third Generation<br>also known as UMTS / WCDMA / CDMA2000</td><td>Up to 2 Mbps</td></tr><tr><td>2G</td><td>GPRS <br>(General Packet Radio Service)</td><td>Up to 64 Kbps</td></tr><tr><td>No Symbol</td><td>If signal bars get more than 1 bar<br>you can use voice call</td><td>No</td></tr></tbody></table>

### &#x20;Signal Strength

We should input a "Fair" signal level for the 5G router. Typically speaking, 3-5 bars indicate a good signal, while 1-2 bars indicate a poor signal. No bars mean no 5G signal detected.

You can run a basic test on a mobile phone. Insert the SIM card used on the router on a mobile phone. Disable Wi-Fi on the mobile phone and go around to check its network type and signal bars. Then, choose a location with strong and stable signal reception.&#x20;

The below chart shows targeted signal quality values for 4G-LTE and 3G networks.

<figure><img src="https://2281776451-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FgV6nqomki285by8oRjoy%2Fuploads%2Fprr5DZhVQWNpqiv0Riqt%2Fimage.png?alt=media&#x26;token=2c07c988-314a-43d2-877e-06b68e131dcb" alt=""><figcaption><p> Signal Quality Chart</p></figcaption></figure>

{% hint style="info" %}
The numerical value of 2G and 3G networks is RSSI standard.&#x20;

The LTE network is RSRP standard. RSRP means Reference Signal Receive Power.

The signal values are negative numbers. A number that is closer to zero means a stronger signal. For example, -90 dB is more robust than -100 dB.
{% endhint %}


# Insert A SIM Card

The 5G router uses Nano (4FF) SIM card to connect to mobile internet networks.

Please use Nano-SIM cards (12.3x8.8mm) on the 5G router.&#x20;

Please use an activated Nano SIM card in the 5G router. If you are going to use a new SIM card, please follow the instructions from the mobile carrier to activate the SIM card.

{% hint style="warning" %}
Please always turn off the power while inserting or removing the SIM card.
{% endhint %}

{% hint style="info" %}

### Clean the SIM Card

If the 4G router does not recognize the SIM card or gets an error message such as "SIM card is unavailable,"

Firstly, please verify if the SIM card was inserted correctly.

Secondly, please check if the SIM card is clean, especially the golden contacts.

Finally, if there is dust/dirt/oil on the SIM card, you can wipe it to clean it.
{% endhint %}

## &#x20;<a href="#insert-sim-cards" id="insert-sim-cards"></a>

## Insert SIM Cards <a href="#insert-sim-cards" id="insert-sim-cards"></a>

1. Turn off the power before inserting SIM cards.
2. Use the included SIM pin to push the pinhole gently until the SIM card holder pops out.
3. Put the primary SIM card in the first SIM#1 slot. Ensure the notch is in the inside direction and the pins face down. There is only one correct way to settle the Nano SIM card into the cardholder.
4. Carefully reposition the SIM card holder in the slot and push it back gently.

{% hint style="info" %}
The flat panels of the 5G paddle antennas have a higher performance. Please adjust the paddle direction towards the outside or signal source to receive a better signal.
{% endhint %}

{% hint style="warning" %}
To ensure optimal performance of your 5G router, position the device away from potential sources of radio frequency interference, such as microwave ovens, radio transmission equipment, and high-power electrical appliances.
{% endhint %}


# Power Supplies

The 5G router uses a 12Volt DC power adapter. Please use the correct voltage and current if using other power sources.

The 5G router requires a 12V DC power supply with an appropriate current rating for safe operation. Please use the included power supply on the 5G router.

Connecting the DC power adapter to the 100\~240 Volt AC electrical outlet power, it outputs 12Volt 2Amps DC power to the 4G router.

Once the 5G router is connected to the power source, it will power on automatically, as indicated by the status lights on the front panel.

{% hint style="info" %}
You could exchange the plug if you received more than one power plug. Press the "Push" button and twist the power plug clockwise to remove it.&#x20;

Then, install another plug on the power adapter and twist it in the anti-clockwise direction to tighten it.
{% endhint %}

# Mobile Protocols

Introduction to mobile internet protocols using on the 5G router.

There are three different mobile protocols built in the 5G router. The default mobile protocol is **Mobile Data**. Suggest using the default protocol unless your mobile provider does not support it.&#x20;

### **Mobile Data Protocol**

The default **Mobile Data** protocol supports the below "**QMI Cellular**" and "**PPP**" protocols and works under an advanced mmcli command set. It uses QMI Cellular in priority and automatically switches to PPP protocol when QMI is not supported.

In rare cases, the mobile carrier might request to use the original QMI or PPP protocols, and then you can switch the mobile protocol under the settings of the Mobile interface.

<div align="left"><figure><img src="https://2281776451-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FgV6nqomki285by8oRjoy%2Fuploads%2FquihjICaVU5fpluqZfd3%2F5G-Router_Mobile-Protocol-Options.png?alt=media&#x26;token=ac34993d-37ce-4e06-b3d8-a682e520c6a7" alt="" width="375"><figcaption><p>5G Router Mobile Protocol Options</p></figcaption></figure></div>

###

### QMI Cellular Protocol

**QMI**, short for *Qualcomm MSM Interface*, is a proprietary protocol that offers more accessible and faster connections to mobile networks.

Due to the difference in the modem chipsets, the different mobile modems might use other QMI proxies. For example, Sierra modems use the *QMI\_WWAN proxy,* and Quectel modems use the *GobiNet proxy*. These proxies use the same QMI protocol and provide similar working performance.

The primary difference is that *GobiNet* uses kernel space, while *qmi\_wwan* uses user space. In *qmi\_wwan*, only one process can handle the control port at a given time, while the *GobiNet proxy* allows multiple processes to access the device concurrently.

### **PPP Protocol**

**PPP**, *Point-to-Point Protocol*, is a traditional data link layer communications protocol. PPP protocol has been widely used and is the most flexible for device interoperability.

Some mobile carriers might not support the QMI protocol to connect to their mobile networks. So, we must change the mobile protocol from the default *Mobile Data* protocol to the *PPP* protocol.

# Recovery

Fix the issues on the Internet and wireless networks and rescue the router from misconfigurations.

## Reboot Router

The 5G router has a Linux-based operating system like a regular computer. Rebooting the router can solve mysterious problems, fix Internet connectivity issues, and improve security.

The Internet provider assigns a temporary IP address, which can be changed during a timeout. If the router misses the change, the Internet connection might become slow. The same can happen if too many devices are connected to the router. For example, the routers found channels with less traffic and increased performance speeds while rebooting.&#x20;

#### i. Soft Reboot

After accessing the router, go to `System` / `Reboot`, you can perform a **soft reboot**.

#### ii. Hard Reboot

To do a **hard reboot**, please unplug the PoE adapter, wait a few seconds, and connect again.

# Internet & IP

Run a first quick Internet access test to check Internet connectivity.

## Internet Connection

You can quickly check the mobile connection on the `Device information` section on the front page or go to `Status` > `Overview`.&#x20;

* After successfully setting up an Internet connection on the mobile modem:

  * The `Mobile Connection` field on the column of `Device` information will shows `Connected`.
  * The `Network` section will show the current mobile network gateway in the table of`IPv4 Upstream`.

  \
  *or*<br>
* Go to `Network` > `Interfaces`, the `Mobile` interface will show `Rx/Tx` rates.&#x20;

  * The `Mobile_4`interface shows the `IPv4` IP address. *\*For `QMI protocol` only.*

  \
  *or*<br>
* Go to `Network` > `Diagnostics`
  * Click on the `Ping` button or use the command `ping outdoorrouter.com` on the `Command-line` .
  * it should return `0% packet loss` if everything is alright with the Internet connection.

## IP Address

Go to `Network` > `Interfaces`. On the rows of `Mobile` or `Mobile_4`, you can find the IPv4 IP address obtained by the mobile modem.

### Public IP Address

The mobile carrier usually provides a LAN IP address for the mobile connection.&#x20;

To verify the public IP address, you can first check the above IPv4 IP address obtained by the mobile modem. Then, search *My IP* on *Google* and compare the returned public IP address with the IPv4 mobile IP address.&#x20;

If they are different, it means your router uses a LAN IP address from the carrier.


# Changing Web Port

Guidance of how to change the Web GUI interface port on the 5G router.

The internet operators usually block 80 ports, which are used by the web interface of the 5G router. To access the 5G router remotely on the public IP address, we need to change the port for the web interface.

When the router is turned on, access the command-line interface. Input the below command `vi /etc/lighttpd/lighttpd.conf`. Now, we are in the *command mode* of the VI editor.

* Press "i" on the keyboard to enter the *insert mode*.
* Scroll down to line No.89. The original code is `#server.port = 81`.
* Delete `#` and change the server port to `880`, for example.
* Press *ESC* on the keyboard. Exit from the *insert mode* to the *command mode*.
* Press `: wq` on the keyboard to save the file and exit the SSH terminal.

Input the below command to restart Lighttpd. `server /etc/init.d/lighttpd restart`.

```
######### Options that are good to be but not necessary to be changed #######

## bind to port (default: 80)
server.port = 880
```

Now, we should re-login the router admin at `http://192.168.20.1:`**`880`**. If your router has a public IP address, you can access the router at `public-ip-address:880`.

*\*Besides using the VI editor, you can also use an **SFTP** client software, like **WinSCP**, to edit the `lighttpd.conf` file.*


# Firewall Settings

The router firewall controls the forward packet streams from incoming network interfaces to outgoing network interfaces.

Firewall rules add another layer of granularity to what is allowed to be forwarded across interfaces and which packets are allowed to be inputted and outputted.

## Firewall Zones

The firewall can collect interfaces into zones to filter traffic logically. A zone can be configured to any set of interfaces. This simplifies the firewall rule logic somewhat by conceptually grouping the interfaces:

* A rule for a packet originating in a zone must enter the router on one of the zone's interfaces,
* A rule for a packet being forwarded to a zone must exit the router on one of the zone's interfaces.

After accessing the router, go to `Network` > `Firewall` to enter the `Firewall - Zone Settings`.The `SYN-flood protection` is enabled by default. You can use the default firewall zone settings below in most conditions.

<figure><img src="https://2281776451-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LvFmeL2Pv0EF2-7nON9%2F-LxZyv7tzLU4F4jop0jB%2F-LxZz9MrAVtqrSRJv0k4%2Fimage.png?alt=media&#x26;token=9673f210-91f5-4f3b-a4cb-55f2bd4a7c49" alt=""><figcaption><p>Default firewall zone settings</p></figcaption></figure>

## &#x20;<a href="#port-forwards" id="port-forwards"></a>

## Port Forwards <a href="#port-forwards" id="port-forwards"></a>

Port forwarding is an application of network address translation (NAT) that redirects a communication request from one address and port number combination to another. Port Forwarding allows remote computers to connect the outdoor router within a private local-area network (LAN).

### i. General Settings <a href="#i-general-settings" id="i-general-settings"></a>

Log in to the router, go to `Network` > `Firewall`. \
➀ Under the tab of `General Settings`, change forward to `accept`. \
➁ In the **Zones** section, change the **Forward** on the row of **WAN** from `reject` to `accept`. \
Click the **Save & Apply** button on the bottom right corner.

<figure><img src="https://2281776451-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LvFmeL2Pv0EF2-7nON9%2F-MAvUwpP9uQPquAbNyY3%2F-MAvVQO0M7JyKjsTjBm_%2Fimage.png?alt=media&#x26;token=c44784c9-41e8-4ede-9e25-f13a669aff4b" alt=""><figcaption></figcaption></figure>

### ii. Port Forwards (WAN) <a href="#ii-port-forwards-wan" id="ii-port-forwards-wan"></a>

Click the tab `Port Forwards` to enter the configure section on the **New port forward** section:

1. `Name` : Enter the reference name. e.g., *`Test`*
2. `Protocol`: Select from `TCP`, `UDP`, and `TCP+UDP`

   📌 *If you don't know the protocol, please choose TCP+UDP. Please select TCP or UDP if you are aware of whether it is TCP or UDP. It can effectively reduce resource consumption.*
3. `External zone` : Select `WAN`
4. `External port` : Set the port number you want to access from the external network \
   📌 *Suggest selecting the WAN port between 1025\~25534. Do not use the standard ports occupied by the other services such as 23, 80, 433, 3389, 7700, 10080, etc.*
5. `Internal zone` : Select `LAN`
6. `Internal IP Address` : Select from the list of connected intranet hosts \
   📌 *If you can not find the host on the list, please recheck the IP settings on the host.*
7. `Internal port` : Choose the port number that needs to be forwarded from the intranet host
8. Click the button `Save & Apply`

The below example was forwarded to localhost *192.168.30.113:80* to WAN port *1180*. You can access the *80* port on the host of *192.168.30.113* from the public IP address plus port *1180*. It's NOT accessible from the router's local IP, e.g., *192.168.30.1:1180*.

<figure><img src="https://2281776451-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LvFmeL2Pv0EF2-7nON9%2F-MAvUwpP9uQPquAbNyY3%2F-MAvVbryHoe0XevYYz94%2Fimage.png?alt=media&#x26;token=88198e7a-c091-4e2d-b929-e1cc22c9403b" alt=""><figcaption><p>5G Router Firewall Port Forwards</p></figcaption></figure>

**NAT Loopback** is turned on after saving a new port forward rule. It allows the intranet terminal to access the local hosts by using the public IP address of the routed external network interface. To reduce the consumption of router resources, you can click the **Edit** button on the saved port forward rule list to disable it.

​

### iii. Intranet Forwards <a href="#iii-intranet-forwards" id="iii-intranet-forwards"></a>

To access another host from the router IP address, we can set up intranet forwarding based on `iptables`. Go to the tab `Custom Rules`, add the new iptable rules. Below are the example codes to forward 192.168.30.113:80 to router IP 192.168.30.1:1180.

`iptables -t nat -A PREROUTING -d 192.168.30.1 -p tcp --dport 1180 -j DNAT --to-destination 192.168.30.113:80 iptables -t nat -A POSTROUTING -d 192.168.30.113 -p tcp --dport 80 -j SNAT --to 192.168.30.1`

# Bootloader

Rescue the 5G router from the "brick" mode.

The router will be stuck in the reboot cycle when the firmware is incomplete or broken. The router keeps rebooting, and WiFi & LAN cannot hold for over 3 minutes.

It usually happens because of deleting critical files or disconnecting from the power supply while resetting or flashing firmware. The 5G router has a built-in uBoot bootloader to rebuild the firmware system.

### Static LAN Connection

# Troubleshooting

The collection of the problem elimination process.

## Changing Password

**i. Wi-Fi Password**

The default Wi-Fi network is turned on and without the encryption password. You can refer to Wi-Fi SSID & Password to configure the encryption type and password to secure your wireless networks.

**ii. Router Password**

The default router password is `root` or `admin`. After accessing the router at **`http://192.168.20.1`**, go to `System` > `Administration`, you can change the router administration password.&#x20;

*\*The default router username is `root`.*

## Forget Router Password

The default login password is empty. If you have changed the router password and forgotten it, please reset the router to default settings. It will erase the previous configurations, and you can log in to the router again with the above default password.

## Wi-Fi SSID and Password

The Wi-Fi network is turned on by default. The default Wi-Fi SSIDs are `Cellular-WiFi-xxxxxx-V4 (and V5)`. It's without the encryption password. You can refer to Wi-Fi SSID & Password to configure the encryption type and password to secure your wireless networks.

## Disable Wi-Fi Network

To disable the Wi-Fi network, please access the router at `http://192.168.20.1`, go to `Network` > `Wireless`. You will enter the `Wireless Overview` page.

‌ You can click the **`Disable`** button to turn off the Wi-Fi hotspot.

*\*If the Wi-Fi network is in the `mode` of `Client`, the Wi-Fi network is for the Wi-Fi relay connections.*

## Can Not Find Wi-Fi Hotspot

Please check the below indicators on the EZR24-5G router.

1. **System Indicator**<br>
   * If the system indicator is **off**, please check the connections of the power adapter and electric outlet.
   * If the system indicator is flashing, please wait 2-3 minutes until the router boots up.<br>

2. **Wi-Fi Indicator** - When the system indicator stays green, check the Wi-Fi indicator.<br>

   * If the Wi-Fi indicator stays green, the Wi-Fi network has been enabled, but no data is streaming on the Wi-Fi network.&#x20;
     * You can try to search for the Wi-Fi hotspot. Remember, you might have changed the Wi-Fi SSID name once before.
     * If you enabled the checkbox `Hide ESSID`, please manually input the device's Wi-Fi SSID name and password.<br>
   * If the Wi-Fi indicator is off and the Wi-Fi network has been disabled, please access the router with the LAN cable connection and enable the Wi-Fi network.

3. If the LAN cable connection does not work, reset the router to default settings.

## Reset the Router

You can use either a soft reset or hard reset to erase the configurations on the router and go back to the factory settings.

‌ The suggested way is a [**soft reset**](https://indoor.router.works/ezr24-5g/manual/pages/ZOx9Ekkf7GsrOn6E7KHJ#i.-soft-factory-reset). If unable to access the router, please do a [**hard reset**](https://indoor.router.works/ezr24-5g/manual/pages/ZOx9Ekkf7GsrOn6E7KHJ#ii.-hard-reset) by clicking the reset button for 5 seconds when the router is turned on.

‌ If the hard reset does not work, please refer to [**EzBoot**](/ezr24-5g/manual/advanced/bootloader) to rebuild the firmware system.
