[RUT200] Modem often unreachable after firmware upgrade

RUT200, when upgraded to newer firmware (and also updated modem firmware) I often get “modem unreachable” message.

To solve the issue I updated to latest available firmware (RUT2M_R_00.07.13.3) without success.

lsusb gives me only 2 entries when modem is missing.

Any suggestion?
I’ll try to go back restoring old firmwares…

Can you post a screenshot of ‘lsusb’ results?
Usually your modem is unrecoverable if lsusb only shows 2 devices.
Means you need to RMA your router if you’re still in an RMA window or it’s finally broken if you’re after warranty.

Hello @elberto,

Is the device unable to connect to the modem at all times, or does it occasionally establish a connection and work on the mobile network?

Additionally, could you please provide the lsusb output when the modem becomes unreachable?

Best regards,
