There are two services to manage networks:
network - legacy service used on Fedora
NetworkManager - meant to replace network service

You want probably use just one of them.

So to use 'network' service, stop NetworkManager: service NetworkManager stop
and disable it not to be run any more: chkconfig NetworkManager off
Then you can manually configure ifcfg- files and do ifup/ifdown.

NM applet is a client for NetworkManager daemon. When you click an item in NM 
applet, it communicates with NetworkManager daemon via D-Bus to activate the 
network connection.
