6.4 Signal Strength
Guidance to check the accurate cellular signal strength information receiving on the EZR23 router.
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.
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.Command
