How to test an WR44V2 step by step.

CHECK W-WAN SIGNAL STRENGTH
Whilst the internet link is still connected from step 7, access the CLI (Command Line Interface)
Access to the CLI (Command Line Interface) – this can be achieved:
Through the serial port @115200 bps
Via a telnet or SSH connection
Via the “execute a command” page of the web user interface.
And issue the following command:
modemstat ?
Check that the signal strength is roughly what you normally get (+/- 10dB) with the same antenna in
the test location.
If the signal strength is much worse than normal, make a note of the cell ID (lac:00DF ci:01B0BD51 in
above example) and repeat the test on a known working WR44v2 that contains the same type of radio
module in the same location. Ensure the known working WR44v2 is connected using the same
antenna and connects to the same cell ID (lac:00DF ci:01B0BD51 in above example). If it does and the
signal strength is much better (+ 10dB) than the suspected bad router, request an RMA from Digi
technical support with code: “Cellular signal strength low”
