Windows 8 Pro Ethernet Connection "limited"

I've been cleaning up this Windows 8 Pro system and last ran adwcleaner.  Now the wired / ethernet NIC doesn't work.  Neither does it work with a static IP nor via DHCP.
Wireless connections work fine.
The wired connection says: "limited" indicating that the physical connection is recognized.
I downloaded and installed a new copy of the driver but no joy with that.
I've reset the connection a few times.
etc.

I need to get the ethernet interface working.

Ensure tcpip and client for Microsoft networks are ticked.

Otherwise, using device manager, remove the nic and drivers and reinstall them

In addition to the above, run TCP/IP Reset

Open cmd.exe with Run as Administrator
Then  netsh int ip reset c:\resetlog.txt
Restart the computer
Remake wireless profiles as needed

Also, ipconfig /flushdns followed by net stop dnscache followed by net start dnscache

OK.  I had already done those things I think but I repeated them all.  And, included Microsoft Fixit 20140.
No change.

Note that the wireless NIC does work which suggests that there is plenty that's working.
And, the Ethernet NIC *did* work until a few hours ago.  And, it *does* know that it's connected.
Getting APIPA IP address on the Ethernet NIC.  Thus, "limited".

Try running DISM (for Windows 8)

Open cmd.exe with Run as Administrator.
DISM.exe /Online /Cleanup-Image /Scanhealth (takes 15 - 20 minutes).
DISM.exe /Online /Cleanup-Image /Restorehealth (takes 15 - 20 minutes).
Restart the computer and test.

I See two possible reasons nit yet discussed: The driver is altogether wrong or the NIC is defective.
To rule out both, I would start a live system, either win8.1 to go or knoppix and see if it works there and what card is detected.

It worked under Knoppix and then, after that, it worked....

Since knoppix does not influence windows, I wonder what is going and and expect the problem to return (unless you have done anything in between that you haven't told us)

Thanks for the update and I was happy to help. I wonder if a complete shutdown and startup influenced the application of the wireless profile.

John Hurst:  I don't think so.  Actually the wireless profile has always been fine.  It was the Ethernet part that was broken.  I should have mentioned that I did run DISM also but I wasn't too good at getting the commands right (as I didn't have your suggestion in front of me at the time).  But maybe this was it....
