with a different stick (Ralink Technology, Corp. RT5370 Wireless
Adapter) it seems to work just fine
=> imho unlikely avahi's fault here

regarding the traffic dump i was very unclear:
the dump is from the requesting host, and yes i also should also take a
dump on the host that is supposed to answer

jens

PS: i have seen similar problems with other sticks - often a workaround
was to disable power saving
