    AC 7260 Windows 10 Unrecognized 20.10.2


      I was currently running the 20.0.2 driver set that worked fine.  I have a Lenovo T440s.  Their system update software, updated the driver to 20.10.2.  It was listed as "critical" and was auto updated. Once the update happened, windows saw the network adapter in Device Manager, but there was a yellow exclamation, and the system did not have any wireless connectivity.  I tried rebooting to see if that had anything to do with it, and it got stuck on the "restarting" screen.  I had to hard power it down after waiting 10 minutes.
