I broke it. :(

Hey guys,

I followed the first set of instructions on this page to get wifi working: http://wiki.centos.org/HowTos/Laptops/WpaSupplicant

That worked! Great!

Now, I want to go back to a wired connection, but NO DICE!

nmcli -d says my device is 'disconnected'

ifconfig -a shows no inet address

I've tried 'sudo service network restart' (which hangs for some time before failing), and 'sudo dhclient enp0s3'

What to do now?

OK, networking started working after I deleted the UUID= line from my ifcfg file, but... that line was always there, so I'm really confused about why that would make a difference. Weird.

I'd still like to know more info about this, and any thoughts on what was causing the issue. Why would a UUID that was always there suddenly stop working correctly? Why would removing that line fix the network connection?
