Public bug reported:
Binary package hint: network-manager
Ever since I upgraded to Gutsy (fresh Tribe 5 install, by the way, just
in case you wondered) wireless networking started going weird, got fixed
somehow just to show even stranger issues. I'll report some of them
seperately.
First of all, I use an on-board IPW2200 WLAN adaptor which connects to a
Linksys WRT54G most of the time. I didn't get the chance to test it on
different setups, yet.
The main issue at the moment is the general instability of my connection
causing loss of signal and having to reconnect to the AP. Most of the
time this goes without much trouble, however, sometimes it keeps trying
to re-connect until the Network-Manager Daemon itself shuts down
removing the nm-applet from the notification area, even though the
process is still visible in the gnome-system-monitor. Unfortunately this
has always happened while I'm was away from my laptop and I can't tell
what happened before.
Fortunately there is a log which I'll attach:

It always ends like this, but I don't understand why. Sometimes the "Signal 11"
line comes first.
