Comment 10 for bug 273860

Okkkkkk.....

It worked fine on another account, so I guessed it's something to do with local configuration.

It indeed seems so.

I removed all wireless-related settings from Programs -> Accesories -> Keys and encryption

Also looked into policykit, but skipped that.

Another issue I found was that in ~/ the folder .dbus was chmod'ed 700 and owned root:root. I chown'ed it to myuser:myuser, rebooted, and it seems to work fine.

Try just looking for ~/.dbus, if that is not there, try removing your old configs.

Seems to work over here (tho I had to start nm-applet manually this time, we'll see on next reboot)

Cheers!
