Ok, but still unclear where the problem is sitting.
Someone tested elrepro or my vanilla kernel

Via the printer's settings options (GUI) and there should be a drop down
for color options (in the past I've set color, grayscale, black).

Or you could use lpoptions

Is NetworkManager-wifi installed?
I remember after I installed Centos first time (7.0) wifi worked.
When I later did a reinstall (7.2) during installation wifi worked fine,
but after a reboot not.
Seems NetworkManager-wifi did not get installed by default.

Anecdotal evidence only so take with a pinch of salt ;-)

I  installed 7.0 on a Dell laptop E6500 wifi worked.

I logged on remotely to do the update to 7.2 ( 7.1511 ) and at the 
same time I was pinging the laptop from another terminal. This should 
give me some idea of when wifi stopped working.

When the wifi stopped working, the pings stopped, in the update window 
the cleanup after the install was taking place and had stopped at 
cleanup of wpa-supplicant. Don't know what significance of that is.

Hm, but let me drop a note:

I’m on a *most* clean installation of 7.2 and other wifi it works.

I Installed the „Gnome Desktop“ who give me the graphical network manager,
but with another network card for sure.
