I was cable connected and I connected also with a wireless connection, networkmanager say me that wlan0 is connected but doesn’t show the active connection when I click on it in system tray, the active connection section is empty, , I have to detach cable to disconnect and then to reattach cable to automatically reconnect, then networkmanager shows both active connections, is it a bug or a feature??
I have no idea, but what struck meas strange is you mentioning wlan0. That device name is no longer used, at least since openSUSE 13.1.
The device name should not be changed when you upgrade, and it is perfectly possible to change it to anything you like, even wlan0.
And in fact on my system it is still called wlan0:

plasma-nm is working fine here though, and correctly showing the active connection:

So if it’s not working for you, it’s probably a bug or misconfiguration.
Check that “Show sections” (“Abschnitte anzeigen”) is activated in the configuration dialog.
Also, my connection is setup as system connection (“Allow other users to connect” or similar). Maybe this makes a difference?
