802.11a definitely not. I don't know if all 802.11n cards have a fallback
to 'b' or 'g'. I suspect most of them do, since 'n' is relatively new, so the
vendors need to provide backwards compatibility.

Well what I want to do is put a wireless card in my Linux server and
configure that as a router. So if I buy an 802.11 b/g card. Will people
with computers that have 802.11a or 802.11n card in them be able to
connect to my network.
