check all your cables, make sure windows firewall is disabled (crap anyways) and yeah like tim said, it sounds like your signal is cutting in and out. could be a problem with your router.

I'm not usiing the wireless feature on it. It has all the things on it to use just regular cables so I went with it. It's wierd it acts like whenever its hooked up it trys to dial a connection and use broadband at the same time
