  Sometimes it does. Sometimes it doesn't.

  Read http://deployingradius.com/

  It has detailed instructions for configuring FreeRADIUS, for WiFi
access.  If you follow the instructions, it will work.

  That is good, but it isn't enough to make WiFi work.

  Then your Access Point hasn't been configured to do RADIUS.  Or, the
firewall rules on your RADIUS server are blocking RADIUS packets.

  Then the RADIUS server didn't receive any request at all.

  You don't need anything special on the client.  Certificates help, but
see the http://deployingradius.com/ guide for details.

  They seem OK.

  Yes.

  Find out why the RADIUS server isn't seeing packets.  Do network-level
/ firewall debugging.
