** here you likely receive the message that the system managing the network is
NOT compatible with what GNOME expects. GNOME can only interact with
NetworkMAnager. If you get this message, you're likely running wicked.

Not surprisingly, this won't work. After all, GNOME did inform you the network
service was not compatible; how could it possibly manage it?

As Bernhard mentioned, you have to switch the Network Management Service to be
NetworkManager inside yast.

Please attempt this and report back how this goes.
