    installing the rtl 8188cu card?

    i have a wireless card here ive been trying to get working for days now. ive tried numerous things, downloading drivers, downloading everything i can but i just does not work.

    the wifi will stay connected for a few minutes at best the i get no connection. so i have to unplug my wifi card and reinsert it.

    ios this device supported on 12.04? what do i have to do to keep it connected?
