And it was not my laptop. It was the last update the router maker put out. I was puzzled but found other PCs would connect and something truly odd is that my machine would connect if I turned on my Kindle Fire HD.

Off to google and sure enough folk were reporting issues with that router maker.

Thankfully the fix was easy. And the symptom of resetting then it worked is the same so let's hope you can tell more about the router.
