Go into Control Panel>System>Hardware>Device Manager and scroll to Network Adapters. You'll see a yellow mark by the wireless adapter - right click it and go to Properties then Driver and finally click on Update Driver. Chances are, XP won't have the right one built in or it would already have installed it so cable to your router so the system can search online for the right driver.
thanks but a little late answering. without that wireless its not even possible to connect at all so that wouldn't be of any help. I even found the right driver for it installed it and it didn't work so I got real help for it. thanks anyways
