Hi guys..I have installed 2 of these on xp already but this 3rd computer just won't recognize the driver. What's the deal? It is D link DWL 520 A revision. I even went to the website and downloaded the updated driver. There is still a yellow questionmark next to Dlink adapter in the hardware devices. I also ordered a bios update for this computer and that won't work. The computer is not that old..what can I do?
