It looks like EAP authentication is completed successfully and so is WPA
4-Way Handshake. However, the AP seems to be re-transmitting Group Key
message 1/2 which could indicate that it does not receive message 2/2
from the supplicant. My first guess would be that the WEP104
configuration for a group cipher is breaking unicast encryption for some
reason. I don't think I have ever tested this kind of combination with
madwifi, but I have seen it working with another driver. In other words,
this could either be a problem in the driver or some kind of mismatch
between the driver and the way wpa_supplicant is configuring the WEP key
for broadcast frames.
