His setup is static key wep; not wpa so I don't think wpa_supplicant is
the issue.
Matthias, your tcpdump of the dhclient packets isn't usable; please try:
tcpdump -i ath0 -n -y IEEE802_11_RADIO
I reviewed the driver to the code in HEAD and the only difference in the
crypto area should not matter in this case. It's possible wme is
somehow enabled and causing problems but the ifconfig output doesn't
indicate that.
If you can find out the model of ap that might be helpful.
Unfortunately the best thing to try is HEAD.
Sam
