installed a wireless network for a friend, one computer is hard wired into the smc wireless router the other machine is in the basement with a dlink dwl-112 usb card in it, the dlink software shows connection but i cannot get anywhere on the net, also if i run ipconfig from dos it gives an error, now this machine was up and on their net like 3 days ago before they got the new computer, any suggestions, oh yeah the computer that isnt working is running win2k sp3 and the dlink software shows connection anywhere from 30% to 85% generally around 70 though
