ok here is what I am doing.
I am creating a client to authenticate via EAP-TLS.
I didn't fragment the message in which I send the client certificate, I
thought that should work and that I would eliminate one error of me
malforming the packet (if I could verify that one large packet worked I
could then start fragment it)
so I send a packet of around 1730 bytes.
The AP is connected to a hub so I can monitor the radius packets it sends
and I noticed it never send a radius packet when I send my TLS packet on the
wireless adapter. I reduced and just send 1400 bytes (a malformed packet)
but now it did send a radius packet, so this means that my issue is that I
can't send 1700 bytes or so and I have to fragment it.
I noticed that the wzc sends the client certificate in fragments of max 1508
bytes, is this a good value for me to use too?
how can I know the limit? if 1508 works but 1730 doesn't. (or should I just
set it to max 1500)

regards
Niklas
