My computer did the same thing when I downloaded that driver!!! I just figured it was something wrong with the router or something so I just went out and bought some networking cable and ran a hard line to my comp.

But my wireless did the same thing....the speed of the connection varied a lot and it would lose the connection a lot and get it back and the internet was very very slow. And did you know you can switch which program to use with your wireless? You can use that Intel that you just downloaded or you can right click and switch back to...I think it said Windows....but neither one seemed to work for me
