If you use Networkmanager and multible network connections in BE::Shell it could be that you are missing an applet for it.
But you can use network manager from GNOME (tested in Kubuntu 12.04, 14.04):
1. Install network-manager-gnome
2. run nm-applet from runner (or krunner (alt+F2) if it is not disabled) or add nm-applet to your autostart
that's it! If you test it in other distributions, please give me feedback!
Update 07/2015: the package in Arch/Manjaro is networkmanager
