I have a windows xp pc that I am trying to set up to be wireless. The wireless router is a NetGear (ugh lousy support)router, the system I am trying to connect to is a dell system. so far I am able to connect my laptop to the wireless router and it works great, however the pc I am trying to attach to does not have a built in wireless connectivity. So I have received a little thumb type connection fropm a friend. When I plug in this wireless adapter to an open usb port it states it cannot find the files it needs. Is there some sort of driver I need to install and if so where can I download it from and I assume (?) it is at no cost. Either way can someone help pls. thanks
