First of all are they two different units?  I have one which just says 1000 on the under side. When I got it Pinnacle supplied a Pinnacle branded 802.11G card which I never used since I preferred to use a wireless bridge. But I now want to use the wireless card but when I slot it in, while a card is recognised (Showcenter wants to reboot) if I scan for a network it says WiFi card inserted or faulty. And this occurs on two different cards (same type).

 Is there a 100G that only supports this card or is there a firmware release perhaps I need to apply?

Thanks
