Fedora 20 'cable unplugged' error

edit

Hello,

I just installed Fedora 20 on an Asus x552cl laptop. Dual boot with Windows 7.

The network connection has an 'cable unplugged' message, even though the cable is plugged in (and working in windows).

I don't really know what I'm doing, but I've seen the information requested in other similar posts:
