I recently configured my Ubiquiti/Ubnt Unifi wireless access point to use WPA Enterprise (wpaeap) and pointed Radius at my domain controller running Network Policy Server (NPS).

I could connect fine using my Android mobile but could not connect from my laptop. Logs in the event viewer indicated an authentication issue, but this was definitely not the case.

After lots of fiddling and googling I discovered that PEAP does not work with wildcard SSL certificates. I replaced the certificate with a server specific cert and voila.

Here’s an article which shows you where to change the certificate;¬†https://cantechit.com/2015/07/10/windows-nap-as-radius-in-a-windows-7-server-2012-wireless-world/
