Suddenly by some unknown reason (only thing I can think of is possibly a suspend / power cycle), the nm-applet in the notification area disappeared. Networks which were configured to connect automatically still connects, even after rebooting, but I can not connect to networks which required me to activate them manually (like my 3G modem). The 3G modem works without problem if I boot in to OS X though.
After I go "little up-arrow in notification area > Add/Remove applets > Restore to default", the icon appears again, but only contains the button "Network settings", but does not list any available networks, even though I am actually right now connected to a wireless network that has auto-reconnect configured.
When I click the network settings button in the popup, I get a message saying: "The system network services are not compatible with this version".
NetworkManager itself is running though:
Code: Select all
$ ps -efw|grep Network
root 2362 1 0 10:34 ? 00:00:00 NetworkManager
If I try to run nm-applet manually, I get:
Code: Select all
$ nm-applet
