My Xbox 360 was working fine the other day before taking everything out completely (carpet fitting). Upon plugging it in again I now get disconnected randomly from Xbox Live at random intervals. I can sign straight back in again no problem. I can't diagnose whether it is the cable, the 7 port switch that it is plugged into, the actual Xbox itself. I've tried changing the cable and slot in the switch. Will try the new cable later tonight.
