I have some issues with one of our RUTX09 routers. It will often lose its connection. The router downstream reports the RUTX09 to be disconnected/connected multiple times as if it would have been rebooted. When this happens it will usually come back online after a few minutes. However, sometimes it will not come back online but lose its mobile connection entirely. When logging into the RUTX09, I can see that MOB1S1A1 is stopped. The mobile option is gone and the device needs to be restarted to get it back. I tried factory reset and updating to the latest firmware which did not solve the issue. Any advice?
