Ahh, the beauty of bloatware. Alas, over the last two or three years I've watched as Linux developers push new "management" software that does things behind the scenes like Windows. Pulseaudio, NetworkManager, SELinux, all three of which I either disable or remove after every upgrade, much to the chagrin of these well meaning programmers. Here I go again, after I swore to myself not to bite the hand that feeds me - in this case all the Linux developers that make it possible for me to run a free, good operating system. My recommendation in your case is remove NetworkManager.
yum remove NetworkManager
Take back control of your computer. Now, before I catch he** from the developers just let me say this. Linux started out as a way to have complete control without background supervision. What happened? When did it become so important to be like Windows?
