Sony Vaio PCG-XG9
Netgear WG511T

from rc.conf:
ifconfig_ath0="DHCP ssid Doke wepmode mixed wepkey 0x2718281828"

with kernels prior to 2007-08-24 15:44:27 UTC the above config was
sufficient to associate with AP defined above using WEP, get an address,
etc. assigned by my dhcp server, and use the network.

with kernels after that time i could see all traffic crossing the AP with
tcpdump, but nobody received my packets. once i found the breaking point,
i figured out that adding "deftxkey 1" to ifconfig_ath0 solved my problem
for newer kernels.
