Again GL-MT300A requires rebooting often routers hardware

Hi, I have the same problem with GT-MT300a as in topic from bacon dd Mar 13. In my case router looses connection with my ISP. After rebooting the connection appears again. Firmware 3.100.
I had not such problem with AR-150. Pls help to resolve the issue.

When an exception occurs, can you provide the system log?
You can export logs from advanced - >Status → system log.

The issue does not appear last time. Thanks.
