Public bug reported:
Binary package hint: linux-ubuntu-modules-2.6.24-12-generic
I've observed this several times, not often. I start a large download,
and the iwl3945 connection simply goes down and does nothing anymore.
Here's the dmesg output from the link association:
[ 420.161250] ADDRCONF(NETDEV_UP): wlan0: link is not ready

Then I started some large downloads, and the trouble started somewhere

And then it went silent for two hours until I came back and found out
that my downloads had failed. Network Manager did not list any available
networks at this time, while it normally shows about four of them.
Doing:
sudo rmmod iwlwifi
sudo rmmod iwlwifi_mac80211
sudo rmmod cfg80211
sudo modprobe iwlwifi
sudo modprobe iwlwifi_mac80211
sudo modprobe cfg80211
fixes the problem, the network comes back up fine after that. I don't
know if the 80211 module reloads are really required, I did those just
to be sure.
