No, but adhoc mode has not been well tested. 11a or 11b? What version of
the software? Have you tried enabling debugging and packet dumping on the
interface (ifconfig ath0 debug link2) to see what's happening?
If you're getting multicast traffic but not unicast then it sounds like the
BSSID isn't setup correctly--which was a very old bug.
