It might be EAP-identity packets hitting timeout/retry limits, due to 
wireless-level problems (interference, poor signal). This is very 
common, and lots of people tend to "associate" (pardon the pun) the 
problem with authentication, but in truth the identity request is really 
"just prior" to auth starting. It's only once the client sends an 
identity response that EAP gets started.
