  What is the user system running?  How does it authenticate?

  That's good.

  That's not.  You haven't described what you're using to authenticate.  Where does it get the certificates from?

  The certificate store you edited is used for web authentication, not WiFi.

  You need to read the documentation for your system to see how to get WiFi authentication working.  This isn't a FreeRADIUS issue.
