The wireless worked fine on 10.04, but fails to connect with the new LTS system (32 bit).
The failure is:
[ 3262.329542] wlan0: authenticate with 00:26:88:e6:db:34 (try 1)
[ 3262.331556] wlan0: authenticated
[ 3262.361303] wlan0: associate with 00:26:88:e6:db:34 (try 1)
[ 3262.365295] wlan0: RX AssocResp from 00:26:88:e6:db:34 (capab=0x411 status=12 aid=0)
[ 3262.365301] wlan0: 00:26:88:e6:db:34 denied association (code=12)
[ 3262.385620] wlan0: deauthenticating from 00:26:88:e6:db:34 by local choice (reason=3)
It occurs only when I connect to a router set to WPA TKIP. Works fine with WPA AES.
I looked for additional drivers with the Wireless connections app and, at the suggestion of a forum posting, installed ndiswrapper-1.58rc1 from sourceforge with no effect. Is there a new driver needed? More generally, are there proprietary Dell drivers tested on 12.04 that I should download?
I noticed that the driver is 64 bit - would upgrading to the 64bit system help?
