Comment 5 for bug 275026

Looking at the dmesg.log, the problem comes right at the end of the entire boot sequence -- and the wireless light is one up to this point, just before the GDM comes up.

The lines:

[ 28.284226] ADDRCONF(NETDEV_UP): wlan0: link is not ready
[ 28.610486] iwl3945: Radio Frequency Kill Switch is On:
[ 28.610490] Kill switch must be turned off for wireless networking to work.

So someplace in there the kill switch was on. I'm not sure what happened in previous kernels, and I can't check at the moment, but when I can, I'll run a dmesg on 2.6.24-19-generic and see what the news is there.
