I need more help than this.  Try supplying some information like the card
type (e.g. 5212) and your setup (station, adhoc, hostap, 11a, 11b, 11g).
Also try sysctl debug.ieee80211=1 and/or ifconfig ath0 debug and look at
the debug messages.

Obviously stuff worked for me before I committed (and I tested all types of
cards).
