I had installed OpenSSL on another computer but no this one.
Thanks for your advice.

Can I ask who to create ca.pem??
I'm very unfamiliar with this.

After I install OpenSSL,
I copy the my-ca.pem to /etc/certs/ca.pem  and implement wpa_supplicant
but screen shows:

CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys
Associated with 00:19:5b:ec:9a:70
CTRL-EVENT-EAP-STARTED EAP authentication started
CTRL-EVENT-EAP-METHOD EAP vendor 0 method 21 (TTLS) selected
