hostapd + freeradius + windows users problem

I've tried with Ubuntu machine and it's doing things as expected so I can
keep tracking users login time and bandwidth(although sometimes there are no
User-Request inside Termination Cause, but that's not important to me).

It's known there are many Windows machines all over there, I don't know how
people aren't having this issue with supplicant.

As I can see, there is not much to do with hostapd/freeradius config to solve
this (I think EAP-AKA and EAP-SIM aren't designed for my network setup).

Thanks for all comments.
