In my home network I connect to the internet via a Comcast broadband modem and my Dell Desktop's Truemobile 2300 router. I have a 2nd desktop connected via wireless USB connection. As a third connection I have a Dell laptop connected via an internal Intel Pro wireless card. I am having problems retaining a connection with the laptop. It connects then drops connection after roughly 5 minutes. That does not happen with the Gateway desktop connected wirelessly via USB. Everything had been working fine until a couple days ago. I suspect downloading Windows SP2 to my main desktop could be the culprit.
