6.4 Signal Strength

6.4.1 - General Signal Info
After accessing the router, go to the front page or Status > Overview. You can find the accurate signal strength information on the Device information section. Click the Reacquire button to get the updated signal strength information.
Since setting up the cellular connection is in the first priority, on the first boot, the Device information will take a few minutes to shows completely.
​
6.4.2 - Instant Signal Info
When you are 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 is 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 either of the below commands to check the instant signal information. Refer to Device information to get the meaning of parameters.
