Public bug reported:
Sometimes (twice in the last 4 hours) wi-fi connection goes down and doesn't
want to reconnect.
When it happens:
* nm-applet asks me for WPA password and tries to connect for a very long time.
* nm-applet behaves strangely - I can't select another network.
* /etc/init.d/networking doesn't help and executes _really_ quickly (0.x
second), producing just one line.
* when I restart gnome, nm-applet doesn't show wi-fi hotspots at all.
* reboot helps.
At the same time, my girlfriends windows-based laptop is connected without any
problems.
I can't reproduce the bug.
I don't know what I can do to troubleshoot this - please tell me and I'll do
that next time this thing happens.
I'm using gutsy (fresh install) since this morning on Dell Inspiron 1720. I
think it happened to me on Feisty (running since I got this laptop in mid
August).
