Have you tested this without WEP? At least some of the packets seem to have been encrypted incorrectly (Rx invalid crypt counter 29).

At least the driver seems to be receiving some packets..

The authentication was using 'shared key' algorithms, so it would seem that WEP is working fine. In addition, association succeeded so everything should be ready for data transmit.

Have you checked with 'tcpdump -ni wlan0' whether the AP is getting any packets when you send something from the associated station?
