Cards seeming connect but unable to route traffic?

Are you running hostapd.
Without it, some cards will conect, but wont route.
also try getting Bridge Utilities
<http://www.eracew.net:/brtools/bridge-utils.tar.gz> and installing
them. Bridging the interfacew should work.
as a note, if you bridge, set the interfaces to promisc with the ip 0.0.0.0
ex:
ifconfig eth0 promisc 0.0.0.0 up
ifconfig wlan0 promisc 0.0.0.0 up
brctl addbr AP0
brctl addif AP0 eth0
brctl addif AP0 wlan0
ifcofig AP0 192.168.2.100
This example assumes that you are using 192.168.2.xx for your ip range.
Hope this helps.
