Yes, I can see it in the certificate list under the 802.1x settings on the properties of the WiFi but I have tried it both, with and with out server validation and no luck. Now it is a self signed cert and I noticed in windows error logs to diagnose the issue it does state eap failure due to certificate issue but don't know how to resolve that since it sees the certificate
Nick, is there any chance you've disabled TLS 1.0 or 1.1 on the NPS server? I tried to do that in an office, but Win7 needed it for the RADIUS to function. I'm gong off the top of my head here, so I can't remember if there's a way to make Win7 use the higher level TLS settings. I went for the easiest solution of turning on TLS1.0 on the NPS server until we complete Win10 Migrations.
