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.
