Public bug reported:
This is a regression found in both kernel 2.6.30-6 and 2.6.30-7, over
kernel 2.6.29 (I have not tested earlier releases of 2.6.30)
Wireless networking in karmic alpha1 will fail to associate with the
access point, frequently on boot, or occasionally may initially
associate and work and later fail. dmesg reports:
[ 6093.506148] wlan0: authenticate with AP 00:18:39:6f:60:02
[ 6093.508226] wlan0: authenticated

[ 6167.608585] wlan0: no probe response from AP 00:18:39:6f:60:02 -
disassociating
Networking is rock solid under 2.6.29.2 on the same system/install.
