That's my site ;-P

The info there is about the only place on the web that describes how 
PEAP/EAP-TLS works, or at least it was when written. It is old now, but 
the config still looks pretty correct. As it says, it's the 
fragment_size thing that actually matters.

Honestly, why? There's no point now unless you want to slow your 
authentication down by adding more round trips. The first paragraph on 
the site says as much.

Microsoft have removed SoH from Windows 10. There's about no other 
reason I can think of to do both PEAP and EAP-TLS.

Just use EAP-TLS on its own. It's simpler, and faster.
