Did you follow the instructions? I had to install the software first with my Linksys wireless card. When I plugged it in, the computer recognized it, installed the drivers and worked. I also made sure I was close to the access point the first time I connected it to the wireless network.
i bought a belkin wireless router and installed no problem, went to install the matching wireless card and it does not work. went into device mgr and there is a yellow dot w/red exclamation point in it.when i checked further, device mgr says "this device cannot start" code 10. any suggestions belkin says i need a bios update.
