just bought a new desktop and it came with windows 7. I have another computer in the living room on windows xp. it is connected to a modem. and has a router connected. bought a wireless usb adaptor (netgear wpn111) and downloaded drivers off website and couldnt get it to work. I then just connected my desktop straight to the router. but still no internet connection. router works for laptops and such. Thought for sure it would work. thx for help.
