Strange symptom on netword.

[jimisbell]

The computer will connect to the network and work fine for 5 minutes and then loose connection. The Cat5 cable that connects the computer to the wall plate for my wired network has been changed twice thinking that was the problem. But it always comes back.

The funny thing is that all I have to do is to pull EITHER end of the cable loose and plug it back in and the problem will be solved for another 5 minutes. Its almost as though there was a capacitive circuit that gets charged up and locks the cable and pulling it loose discharges the capacity and it works again.

Does that make any sense??
