EAP is the generic protocol that can be used with number of
authentication mechanisms, one of which is EAP-PEAP. The main
information in the log is that the specific EAP method could not be
selected for some reason; not that EAP was being used (since that is the
case even with PEAP).

Are you really trying to use a private key and client certificate with
EAP-PEAP? If yes, you would need to add client_cert option here. If not,
I would suggest removing private_key and private_key_passwd since
EAP-PEAP with EAP-MSCHAPv2 does not normally use client certificate and
the client authenticates using a password. Please also note that if you
do not configure the password in the network block, you will need to
provide it during authentication, e.g., with wpa_cli for wpa_gui.

If this information is not enough to resolve the issue, please send me a
debug log from wpa_supplicant (with -dd on command line) showing the
failed authentication attempt.
