> Bug description:
> Network Manager's applet shows no connection. Clicking on it shows that
> all interfaces are in "unmanaged" mode so that Network Manager has no
> control over them. This occurs without the user making any changes to the
> interfaces. User has not manually set the devices into unmanaged mode. How
> to correct it in the Network Manager -> Edit Connections dialog is unclear.
