Nope nothing there for the wireless, although you can probably disable the wired nic in device manager since you're not using it. How about proximity, distance from the actual router, as compared to say the laptops distance from the router. The only other thing I can think of is wireless encryption, Win 7 seems to hate WEP and love WPA2 but if the laptop is working fine then I wouldn't suspect that to be an issue either. Have you tried a different browser just to check, maybe chrome. I don't know, I have to admit, I'm clueless.
