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.
