Same Problem here. I am on a ThinkPad T61p running Ubuntu 8.10 upgraded
from hardy; I too have the 4965 AGN wireless card (home network, Belkin
N router, wep2), iwlagn driver, am using the most current kernel and can
confirm this issue. After following the "Known Issues" caution (about
kernel panic and the 4965 agn on the release notes), I installed the
linux backports which enabled wifi with this card. however, the "hang"
has always been there. I am am idiot brand new to Ubuntu so only after
blamming firefox and opera and reducing them almost to text browsers did
I read the error logs and see the problem. Many people across many
boards are experiencing the identical issue, often under the impression
it is something else.

This appears to be bug 1700 on Bugzilla:
http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=1700

As well as bug 179698 on launchpad:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/179698

And it's very similar to this -which was fixed allegedly:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/264104

I don't use bluetooth so I removed it; one of the posts somewhere spoke
of success after killing bluetooth. My error logs continue to show the
supplicant state change every few minutes:

Nov 24 02:26:21 augusten-T61p NetworkManager: <info>  (wlan0): supplicant connection state change: 6 -> 7 Nov 24 06:19:13 augusten-T61p NetworkManager: <info>  (wlan0): supplicant connection state change: 7 -> 6 
Nov 24 06:19:13 augusten-T61p NetworkManager: <info>  (wlan0): supplicant connection state change: 6 -> 7 
Nov 24 06:52:29 augusten-T61p NetworkManager: <info>  (wlan0): supplicant connection state change: 7 -> 6 
Nov 24 06:52:29 augusten-T61p NetworkManager: <info>  (wlan0): supplicant connection state change: 6 -> 7 
Nov 24 07:25:45 augusten-T61p NetworkManager: <info>  (wlan0): supplicant connection state change: 7 -> 6 
Nov 24 07:25:45 augusten-T61p NetworkManager: <info>  (wlan0): supplicant connection state change: 6 -> 7 

But since removing Bluetooth, I have not observed any interruption in
service. But it remains to be seen whether the disabling of bluetooth
has, indeed, made a difference. A full day of use should tell me.
