Hi,

I have three Deco X55, one of the Deco is connected to main X55 with ethernet cable, it was fine until few weeks ago after a firmware update.

The cable connection is disconnected intermittently, Deco is in green light, no errors, and the TP App tells the device is connected to the other device by WiFi.

I've tried to reboot and reset device, did not make any change. I thought maybe ethernet cable is defective, so I change to new cable but still no luck.

There are three cable sockets on X55, sometimes the cable connection would be back after I swap the cable to the other socket, but sometimes it still no use.

I'm not sure this is firmware issue or it actually is the device faulty and requires repairing, does anyone have the same issue or any suggestions to solve the issue? Thanks.
