No Internet connection on wired Ethernet or wireless

Already uninstalled McAfee Security Center and Malwarebytes. No difference.

I have already performed all those steps.

IP is enabled.

Network Reset within Windows failed.

ipconfig /release and /renew both fail:  "no adapter is in the state permissible for this operation."

Entering ipconfig at the command line returns: "Windows IP Configuration" and that's all.

The results above, accompanied by the fact that onboard Ethernet, PCIe Ethernet, and USB wireless all fail to connect, lead me to believe it has something to do with the operating system. That's why I was asking if the TCP/IP stack can be repaired without completely reloading windows.

(Gateway and wireless access point have also been rebooted.)

Yes, all that has been done.

Try these tools:

Ran sfc & Dism

sfc returned "no integrity violations."

Dism /CheckHealth returned "No corruption detected."

Dism /ScanHealth returned "No component store corruption detected."

So...I have no Internet, but nothing seems to be wrong.

Is this the point where I re-image the machine?

I remind you again that if the firewall / antivirus was not properly uninstalled and completely using the appropriate tool of the manufacturer, any traces left in the computer could prevent the proper functioning of the network connections and therefore access to the internet. In this case the tools sfc / scannow and DISM do not help because they do not find corrupt files. Try again to uninstall the antivirus via its proprietary Remover.
If you're sure about this, try running Windows in safe mode with networking.

When I respond that I have accomplished all steps, it means I have accomplished all steps. Let me be clear: I uninstalled McAfee anti-virus and McAfee firewall with the proprietary uninstall tool, MCPR.exe, downloaded directly from McAfee.

Perhaps if you had paid any attention to my original post, you may have guessed I have some level of expertise above idiot.

I have been working with Windows since v3.1. In 24 years (15 as a computer professional) I have never seen Windows IP connection information completely disappear and not respond to a reset. I was hoping to gain some technical insight as to what caused this, how to fix it, and maybe how to prevent it in the future.

Thank you for the time invested.

Note to others with this issue: I re-imaged the computer and it works fine. I speculate that it was caused by an incomplete Windows Update. My reasoning is that the last update that shows success does not appear if I go to Uninstall Updates. Those of you without a disc image may be able to fix this by reloading Windows (I did not test this).
