Signal Strength

Guidance to check the accurate cellular signal strength information receiving on the EZR23 router.

General Signal Info

After accessing the router, go to the front page or Status > Overview. You can find the accurate signal strength information in the Device information section. Click the Reacquire button to get the updated signal strength information.

Since setting up the cellular connection is the priority, the Device information will take a few minutes to show entirely on the first boot.

Instant Signal Info

When using a directional mobile antenna, you can check the instant signal information to locate the antenna with the best signal reception. The EZR23 router has built-in UQMI and QMICLI commands, which are workable with the QMI-Cellular protocol only.

After inserting a SIM card and the router is powered on, go to the command-line interface and use the below commands to check the instant signal information. Refer to Device information to get the meaning of parameters.

i. UQMI

Command uqmi -d /dev/cdc-wdm0 --get-signal-info

}
