SuperHub 3 keeps dropping connection

HassanM69
Tuning in

Hi my mum's hub 3 keeps dropping connections every few seconds for more than a month now. I have done the following below. The Hub is connected to the PC via ethernet cable, the wifi works as normal.

Rebooted, Reset the Hub, Switched off for 10 minutes, checked all wires, changed the cable to different ports on the hub.

Downstream is too high, should be between -6 and +10.  A technician will need to fix this.
