With Intel WiFi adapters I would suggest to stay away from latest ones,
specifically 7xxx and 6xxx (like 6205, 7260, etc). They will not work (did
not work for me). They need some modifications to wireless stack, after
which their drivers written for Linux could be adopted/modified for
FreeBSD (as far as I understood the developer who can do/does that from
his post). If I'm wrong here, I really would like to see reference to what
I can do to make one of these WiFi adapters work...
