module in the same location. Ensure the known working WR31 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”
7 CHECK USB PORTS
Insert a valid USB device into the USB slots on the front of the WR31. A valid USB device is a device
that you know works in a WR31 because you have tried it previously. Examples to try:
 USB Flash drive
 USB Serial adapter
 USB Mouse
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:
busb show
2 devices should normally be present:
 Device in “BUS 1, dev2, depth 1” (There is a USB stick inserted)
 Device in “BUS 2, dev2, depth 1” (This is a Huawei radio module, do not be concerned if it is
missing, the module may be mid power cycle. The text of this will vary based upon the type of
module fitted. )
If the device in BUS 1, dev2, depth 1 is not present and this same devices shows up fine in a known
working WR31,please request an RMA with code: “External USB port test failed”
