Make sure that for every connection "Allow interface to be controlled by Network Manager" is enabled (see the Drakconnect chapter in our MCC Doku). It can also be easily changed for all interfaces via
Install networkmanager including networkmanager-applet, for example via
and enable automatic startup as root via
at this point your connection will break, if you need it again you may need to run the command
and it will work again for some minutes.
Then disable net_applet autostart (can be done via right-click -> Settings or by putting AUTOSTART=FALSE into ~/.net-applet) and on next boot networkmanager should be in charge. Depending on your setup you may need to kill an additional wpa_supplicant process, which may still be running, as networkmanager spawns its own instance.
