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.
