The networkmanagemnt plasmoid does right now nothing except popup a
message that it's deprecated in favor of the systray applet. Doesn't
matter if it's installed or not. I guess the worst thing that could
happen is that it makes plasma-desktop crash. Well, that would
actually be bad ;)

Do try the NetoworkManager-gnome (nm-applet). I had a different
problem, not solvable with knetworkmanager, but with nm-applet.
