For wireless devices you must install the drivers for it manually. I had a netgear USB adapter and I had to find the .inf and .sys files for that specific adapter. Then you must use a program called ndiswrapper. What distro are you using?
If your using ubuntu, which you might go to this website https://help.ubuntu.com/community/Wi...er/Ndiswrapper
If your using a different one than go to the community site for you distro and type in ndiswrapper.
It also maybe something internal, so you might want to still try what markush says.
