what kind of internet do you have? If it's dial up, it could just be the amount of users near you... all using the same connection as you and clogging up the bandwidth. If it's dsl or cable... it could be a faulty ethernet cable, an internal issue with your mobo, or, maybe with the modem for your dsl or cable. Have you tried your internet with any other comptuer? And, also, please post the specs of your computer. Thanks.
