What files or programs have the ability to change your default network scripts and config

What files or programs have the ability to change your default network scripts and config files? All 3 of these very important files got changed on their own.

/etc/sysconfig/network-scripts/ifcfg-wlan0
/etc/sysconfig/networking/devices/ifcfg-wlan0
/etc/sysconfig/networking/profiles/default/ifcfg-wlan0

Depends. What's your system?

fedora :). Does this forum allow signatures so you don't have to ask every time? I always forget to tell you that.

No, but we do have a Fedora subforum.

It's NetworkManager.

If you don't want to turn the entire silly thing off, it might be better to work with it than to edit config files manually.

Why would it mess with my default settings? It has never done that before?
