What I found was that windows wireless setup was generating another configuration after I finished mine. It did not show up until I tried to connect for the first time.
Then when I opened wireless properties I saw that I had two configurations for the same ESSID.
The fix was to keep the autogenerated one by windows ( it was in all caps) and remove the one I setup.
Also, in wireless properties tab authentication, windows was defaulting to smart card for authentication even though I chose certificates.
Hope this helps. I know your frustration!
