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:

Could you also add the contents of /etc/sysconfig/network-scripts/ifcfg-p3p1 to your original post?

Hello! Just added the result for that command.

In the folder I find a file "ifcfg-lo".

What's the output of:

nmcli device show

Updated my entry with the results for "nmcli device show" command.

I am missing something, there should be a configuration file for the connection, what's the output of:

ls /etc/sysconfig/network-scripts/ifcfg-*
cat /etc/sysconfig/network-scripts/ifcfg-*

if only the ifcfg-lo file exists, maybe you just need to create/modify the connection using e.g. nm-connection-editor.
