Comment 57 for bug 429035

Had a similar problem with Ubuntu 9.10, Lenovo T60, intel 3945Aabg, iwl3945 driver. It worked with 9.04, I suppose because Network Manager was disabled (and I think this was by default). I know I had tried to enable NM with 9.04 but it didn't work so I just shut it back off. I think it sort of worked with NM sometime prior to 9.04, but I always had to re-enter the WPA key every time I rebooted.

Upgraded to 9.10 and discovered NM was re-enabled and I could not get wireless working (using WPA2-PSK). I was getting this:

To make a long story short, I installed wicd and life was good. No muss, no fuss, just installed, rebooted, and wireless linked right up. My Lenovo wireless never had anything but problems with NM. To be fair, I never really dug into what might be causing the issue. It is possible that had I gotten into the NM config files I might have gotten it working, but I really didn't have the time or inclination to do so.
