Failover Modem - D-Link DWM-222 not working
I have a Watchguard T80 running version 12.9.3.
I have a -Link DWM-222 (chosen as it is on the supported modem list) for a failover link.
It has a PlusNet sim, and the USB modem works fine when plugged into a PC.
I have configured the Modem through the web interface. There is no option to select the modem type as detailed in the instructions below.
_To configure the account settings for your modem, from Fireware Web UI or Policy Manager:
Select Network > Modem.
Make sure that the Enable Modem check box is selected.
From the Modem Type drop-down list, select the type of modem to configure._
Also, there is no monitoring option in the System menu as in the instructions below
_To monitor the LTE modem status:
From Fireware Web UI, select System Status > 4G LTE Modem or 5G Modem.
For more information, go to 4G LTE and 5G Modem Status. The 4G LTE or 5G modem status also appears on the Dashboard Front Panel in Fireware Web UI._
The modem appears in the interfaces menu, and the status shows up on the Status->interfaces.
The instructions say it will auto configure for failover.
Auto failover does not happen.
The only error in the log files is
"2023-06-29 13:51:18 networkd get_interface_counter failed for modem0"
from which I would suspect the modem type is not correct - but there is no way to set it.
Has anyone else seen this issue and/or found a way to correct it?
