I received a Cisco Aironet 802.11a/b/g AIR-CB21AG-A-K9 in the mail today and so far it works with my 802.11b hostap box if I lock it into mode 11b. I've got another a/b/g card coming tomorrow so I'll be able to test 802.11a this weekend. Even if I don't get 802.11a working with it this card works much better than the Netgear MA401 card I had in this laptop. I'm consistently connecting at DS11 and have great range.
