# Troubleshooting

## 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. 

*\*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.

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

## No 4G Connections

Firstly, please check if the router has an internet connection on the mobile modem. If there are no 4G connections, please check the below subjects.<br>

* Verify SIM Card Installation
  * [Recheck your SIM card](/ezr23/diagnostics/verify-sim-card.md#re-insert-sim-card)
  * [Check SIM status and registration on the router](/ezr23/diagnostics/verify-sim-card.md#sim-card-registration)&#x20;
* Verify 4G Signal Strength
  * [Find a location](/ezr23/installation/install-antennas.md) with stable 4G LTE signal reception
  * [Test signal strength on the router](/ezr23/diagnostics/signal-strength.md)
* Check Modem Connection
  * Check both the [physical connections](/ezr23/diagnostics/modem-connection.md) and [virtual interfaces](/ezr23/diagnostics/modem-connection.md)

After checking and fixing the issues mentioned on the above subjects, but still have the 4G connection problem, please log in to the router, go to `Status` > **`System Log`**. Copy the system log and :link: [send it to us](https://www.outdoorrouter.com/contacts).

## Slow Speed on 4G

The 4G cellular router relies on the 4G signal to set up an internet connection. Ensure you install the router with a [strong 4G signal reception](/ezr23/installation/install-antennas.md).&#x20;

## Reset the Router

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

‌ The suggested way is a [**soft reset**](https://indoor.router.works/ezr23/pages/grmt8rnvVpinzDNCMr8G#i.-soft-factory-reset). If unable to access the router, please do a [**hard reset**](/ezr23/configuration/recovery.md#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**](/ezr23/configuration/recovery.md#ezboot) to re-flash the firmware.
