knetworkmanager can't find wired lan

Don’t know much about configuring KNetworkManager. I looked in options and can’t find anything that would allow me to help it find my wired lan.

Running Suse 10.3 on a thinkpad. Router is Trendnet wired and wireless router. I recently tried to directly cable my laptop to the trendnet rather than going via wifi (which always worked perfectly). KNetworkManager can’t even find the device.
