802.1x with Cisco wireless controller

Thanks a million for your reply.

But I can't help but be surprised that the access controller is working well with the MS radius server. Since it doesn't, shouldn't it also work with FreeRadius?

  That's expected.

  Blame the AP and/or the end machine running EAP.  FreeRADIUS is sending a response, and they aren't continuing the EAP conversation.

  I've seen this before.  Honestly, I don't know what causes it.  Try... fail.  Try... fail.  Try... succeed. 

  Does the client have a random number generator which randomly fails authentication?  It's bizarre.

  Yeah.  OpenWRT runs hostap for it's WiFi stack.  That code works.  Cisco equipment?  No idea.

  Switch to a different AP.
