Is it NetworkManager or kNetworkManager?

11.3 32bit

My rt2870sta based SMCUSBW-N wifi usb sets up with Yast using either that module or the rt2800usb one. No problems, connects on hotplug. But if I try KNM on it it throws a security dialog three times in a row regardless of what encryption or none I set up and there's NO connection.

Where can I look for clues, if anywhere?
