KDE’s NetworkManager is a nicely integrated plasmoid, however it is missing some features (particularly ones I need to authenticate to University’s network).
It’s easy to swap out KDE’s plasmoid with GNOME’s more fully featured NetworkManager applet. Simply remove the KDE one, install GNOME’s one, tell it to start on login, then just log out and back in!
Remove and install:
sudo yum erase kde-plasma-networkmanagement
sudo yum install NetworkManager-gnome
Then go to System Settings, load Startup and Shutdown module to add the applet to Autostart. Simply click Add program and type:
Log out and back in and you’re away!
