CentOS - Jan 2017 - Reliable way of having both LAN and WIFI on headless box

You could say the same thing about  computers in general:
I hate them, they automated many tasks in life and took many jobs out of the
market!.

Hi Gianluca

Thanks for this.  I will put this into a cron job to bring the link back up
if it drops. However, as you can see it shouldn't ne needed.  One more
reason I hate NetworkManager

[root at lcomp2 ~]# nmcli con show RW-WIFI |grep connection.autoconnect
connection.autoconnect:                 yes
connection.autoconnect-priority:        0
connection.autoconnect-slaves:          -1 (default)
[root at lcomp2 ~]# 


Gary

And they suck. All systems suck. And thanks to that I got my job.
