So far it seems the client connectivity works, Just the bridging of the two interfaces ath0 (Wireless Atheros) and eth0 (LAN ports) is causing problems. I realize kamikaze is not supported yet and not much discussion is going on about it. Many users have been playing with this and this is where I am at currently. I have full client mode WPA/WPA2 connectivity to my AP in Master mode.
