The KDE network manager has *never* *ever* worked for me, over several laptops and Kubuntu versions. In 7.10 I installed gnome just for the network manager, and had a nightmare which resulted in a need for a painful reinstallation instead of an upgrade. I prefer KDE any day but it network manager and X setup with external monitor *never* *ever* worked for me. This is why I can't recommend Kubuntu to my friends.

Sorry about the rant.
