In such case there are options to find a card which was made specific to manufacturer or find the patched bios(or do this by self but that may be very dangerous). I had such situation and went the whitelist way with my Lenovo laptop and I have no more problem with incompatible wireless(wwan and wlan) devices. The two computer manufacturers who are doing such security of their profit are HP and Lenovo. I don't know if others are doing that too. Maciek
