We got a problem, a friend came over with his computer and when he pluggs in his computer into our router (D-link 604) after
som time internet starts to drop and die.
It is down for some 10-20sec then it comes alive for some time and then dies again and so on.
We have 3 computers connected now and 4 with him, all 3 computers have XP and he got Vista.
Something clearly happens when he pluggs in his computer into the router, but what? And how do we stop it?
