Dear lists,

lately i installed my netgear wg511 pci, trying to run it as a AP on my
FreeBSD 5.2-RELEASE using the ath driver.

Now I run into these problems :

dhcp requests are not answered, pings don't work (traffic at all is
unstable)

a tcpdump results in this :

-bash-2.05b# tcpdump -e -vvv -i ath0
tcpdump: listening on ath0

I tried on another fbsd5.2 without a problem... Hardware or config problem ?

Any ideas ? I read a something on http://www.benzedrine.cx/pf/msg03492.html
, but could not see any parallels
