I have a Compaq desktop windows 7 and a Gateway wireless laptop running windows XP. I set up a network so I can share files between both computers. I have an ATT gateway DSL router modem which is a 2wire connection. It worked fine whan I first set it up. Now the win 7 cpu cannot see the laptop XP but the laptop can see and share files with the desktop. When I did a ipconfig on the desktop I got nothing but Media Disconnected. Do the ipconfig on the laptop everything is fine. Anyone know of a solution. I have no problem getting on the internet with either cpu.
