  That's good.  For the benefit of others reading this, what was wrong?

  Good to hear.

  If there's an Access-Accept and the system gets on WiFi, it's OK.  Nothing else matters.

  You need to bypass the captive portal completely.  It has nothing to do with FreeRADIUS.

  Typically you have a "closed" SSID which requires EAP / certificates.  Then, you have an "open" SSID which is controlled by the captive portal.  You can't mix & match EAP and captive portals.  The protocols are designed to make this impossible.
