A complete guess but from hereit sounds like UPC uses PEAP for authentication. Does the ESP support PEAP?

- Tue Nov 10, 2015 5:12 am #33607 Yes, you are right, UPC uses PEAP for authentication.

UPC Wi-Free, I think, the biggest "wi-fi network" in the world!

Can we connect to UPC or not?
Do anybody know about the ESP8266 PEAP support?
