    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

    Regards Kai
