Latest patch, wifi adapter not working

I am running Windows 8.1 and Norton Security. Yesterday, I did a live update and a patch was available that I applied.  Afterwards, I was no longer able to connect to my wireless router. I can see the router, and it is still set to auto connect.  When I tell it to connect, I am informed "cannot connect to this network".  It was fine prior to the patch.  I am connected via ethernet right now.  I tried a restore thinking it would back out the patch.  Nope.  Instead, I had a problem with Sonar and had to use NRnR to remove and reinstall.  That fixed that issue, but not wifi.  I have tried to troubleshoot with windows tools - says it cannot be fixed.  I need help please.
