Some drivers don't process multicast packets properly. You can work around it by setting the "promisc" flag on the interface. See http://avahi.org/wiki/Avah4users#FAQ number 15.
ath9k is quite popular, I have a vague memory that its handling of multicast packets was fixed in a fairly recent Linux kernel, around 2.6.29 or so.
