I have the same problem. I bought a nice D-link DWL-g650B because,
after much googling, I'd read that they had worked for other people.
Unfortunately this is a "B5" with firmware version 2.54. The card
still is identified as an AR5212 chip which means that it's just an
issue of figuring out how to talk to this newest firmware, I hope:

ath0 at cardbus0 dev 0 function 0 "Atheros Communications, Inc.,
AR5001-0000-0000, Wireless LAN Reference Card": irq 11
ath0: AR5212 7.9 phy 4.5 rf2112 5.6 rf2112 5.6, FCC1A, address XX:XX:XX:XX:XX:XX

Some links I found are:
http://archives.neohapsis.com/archiv...5-08/0403.html -
shows someone with the exact same problem as me.
http://archives.neohapsis.com/archiv...5-08/0348.html -
reply to above, suggests that the card is unsupported, however the
post is from august so things may have improved since then.
Unfortunately the poster doesn't give much information except a link
(in a later post) which is now dead. (the link is
http://www.sigmasoft.com/~openbsd/ar.../msg01101.html
if you want to know; it looks like it's from 200507 in misc but I went
searching in the archives here and couldn't find it)

The card is not actually connected to the AP at this point. All you've
done is told it to look for an AP with a SSID of "kirknet" on channel
3, but it hasn't found it.

This seems to be the case. If I turn on debug on the card and do
ifconfig -M ath0 you can see it broadcasting but no results are
returned:

If I set it in HostAP I can't see it from anywhere else.

I'm new to OpenBSD but I'd be also willing to help figure this out if
someone would point me in the right direction. I'd really like to make
this card work. Along the way it would be nice to fix the "unable to
resume HAL (again)" problem that seems to plauge ath(4)
(e.g. see: From Stefan Kaltenbrunner <stefan@kaltenbrunner.cc>

^ sorry for the awkwardness, I don't know how to reference posts on
mailing lists)

Oh, one last question/comment: I've read that D-link likes to disable
promiscuous mode on their cards, and indeed this happens:
+I can't get any packets if I set promiscuous mode from windows
+At home, I get all packets on my LAN in non-promiscuous
+At school I only pick up broadcast and local packets in non-promiscuous
Why would this be? Would the code that blocks promisc be in the
firmware or driver? If it is a driver issue that would be nice because
once we make ath(4) work with the AR5212 my card should be able to do
promisc (at least from OBSD), right?.
