Hi All -

I've TP-Link MR3220v1 running DD-WRT. I'm using it with Huawei E303C modem and everything was working fine till yesterday.

The problem I'm facing now is that my modem (Huawei E303C) is not getting identified by router. I installed TP-Link firmware and still it shows modem as "Unplugged". It also don't show USB system log.

I think that my router USB port is gone.

Do you know any way to diagnose it? Also any experience with TP-Link 3 Year warranty program?

Please provide your inputs.

Thanks!!
 
In log only 12 records were shown and it was not getting refreshed. Anyway, as it was covered under warranty I gave it to dealer and hope to get new piece in a weeks time.
