On my machine (Feisty with latest updates) sometimes knetworkmanager dies 
shortly after login to KDE (then the symbol in the tray is missing). When 
I start it again, it works from then on. You can start knetworkmanager 
from the menu: K -> Internet -> Knetworkmanager.

Maybe this is a dumb question: Did you logout of KDE or even reboot your 
laptop? While I always switch off while the machine is not in use, others 
may prefer to suspend to disk.
