well, here's my problem. i recently put together my bro's new computer with a built in lan card and now, my internet will stop working, ill have to unplug my router for 10 seconds, then it works fine again.

now, im not sure what the problem is. he's running window 2000 professional and im running windows xp. before that computer hes on now, he was on my old machine with windows 2000 and it ran perfectly fine with the router not screwing up or anything.

i have tried everything, does anyone know how to fix this problem?

any help would be great. if you guys need anymore specs just let me know. ill do anything to fix this problem.

also, when he doesnt use his computer, it tends to be perfectly fine. i think its only when he uses kazaa or some other peer to peer sharing program, if this helps any.
