Comment 1 for bug 259904

Actually, if I look in /var/log/syslog, the kernel error code in the the AssocResp is a bit different (18 instead of 128):

Aug 20 11:02:34 platonas kernel: [ 33.381224] eth1: Initial auth_alg=0
Aug 20 11:02:34 platonas kernel: [ 33.381235] eth1: authenticate with AP XX:XX:XX:XX:XX:XX

Google tells me 802.11 status code 18 means "association denied; the mobile station does not support all of the data rates required by the BSS"
