Comment 73 for bug 446394

I moved from 9.10 to 10.04 LTS. I had difficulty connecting to my hidden wifi network at home.
I temporarily configured the wifi as visible and was able to connect.

The problem however did not go away on moving back to hidden wi-fi.
I removed network-manager and installed wicd and removed nm-applet from the system tray.
WiCD did not work either. So I removed it and installed network-manager but found that nm-applet
does not run in the system tray. Going through the various threads I found Alt+F2 would help me run /usr/bin/nm-applet.

When I run nm-applet like this after the system is booted up and I am logged in I find that I am prompted for
the WPA2-PSK key and I can connect without any problem.

Not sure what in all the above steps fixed the issue, but I now manually launch nm-applet.
I would say that launching nm-applet before the system is all booted up is one of the symptoms of the problem.
It seems to work if we launch nm-applet after the system is booted up.

If someone can point me to how to enable debug messages for nm-applet and the source code I could help
in debugging the problem.
