What the heck could be this issue?

I am working with a 2011 Macbook Pro 17"
All of a sudden both WIFI & Ethernet goes out and don't see services in network prefs. Only way to connect to internet on computer is by tethering my iPhone.
Opened up and made sure connections were tight and everything looked okay. Reinstalled High Sierra still the same. Reformatted HD and fresh installed Sierra same - Did it again and installed El Capiton Still the same.
It was at this point I was thinking I needed to replace hardware when........
Took out a USB Drive with a old Backup I took with Carbon Copy Cloner that has Sierra as the OS and booted from the external drive. Everything came up and works perfectly.
Can't be hardware but why will it not work when I fresh install any of the versions of OS X?

- 2011 17" MBP 2.2ghz, 16gig ram, OS 10.11.6
What I would do with the current setup is run the free maintenance app called "Onyx"...and see if that helps. Could also try a PRAM Reset.
