Hi

I bought TS-W8968 4 days ago. I configured it to act as a 3G router using Reliance 3G connection (with ZTE MF190). It was working great.

Suddenly it stopped working and does not connect to Internet any more.

I see the dongle LED blinking while the router says "Disconnected".

Error message from the log file are as follows:

=============================

When I connect the Rleiance 3G dongle directly to my PC, internet connection works fine.

I tried setting factory defaults from the router homepage but still it is not connecting.

Please suggest a resolution.

Thanks
