  EAPoL is EAP over LAN.  It's the communication protocol between the
laptop and the access point.

  i.e. it has nothing to do with RADIUS.

  It isn't a RADIUS issue.

  My guess is that the access point is broken.  Switch it out for
another one, and the messages will disappear.  Don't use the same make /
model.  Switch vendors.
