I've ran into this before. If possible, find out the wireless chip manufacturer on the wireless card. For example, many times the Trendnet Wireless cards have a Realtek chipset. If you google the numbers on the chip, it should take you to a direct driver download (drivers only, no software fluff that comes with the adapters now-a-days). Uninstall the device in device manager, shut down the computer, remove the card, start up the computer, install the drivers (if possible, if not, at least extract them to the desktop), remove the previous program that had control of the wireless card (if possible, if not, try safe mode) then shut down. Install the card again and start the computer. Hopefully it asks you to find drivers for the device, if so, install the one you downloaded. If it installs drivers automatically (didn't happen to me), you can try to tell it to update the drivers for that device and give it the desktop location.
