[Solved] WIFI connection problem after update of OpenSSL

#1 Post by enrico.caruso »

I have a Debian Testing running on my Laptop and after the update of OpenSSL, I can't connect to a Wi-Fi network using WPA2 Enterprise with PEAP (MSCHAPv2).
In the output of

Code: Select all

journalctl -xe
there are the following lines:

Code: Select all

nov 14 17:03:11 nautilus wpa_supplicant[1022]: SSL: SSL3 alert: write (local SSL3 detected an error):fatal:protocol version
nov 14 17:03:11 nautilus wpa_supplicant[1022]: OpenSSL: openssl_handshake - SSL_connect error:1425F102:SSL routines:ssl_choose_client_version:unsupported protocol
nov 14 17:03:11 nautilus wpa_supplicant[1022]: wlp9s0: CTRL-EVENT-EAP-FAILURE EAP authentication failed
I solved this annoying problem following the steps reported here https://unix.stackexchange.com/question ... nsupported, in particular changing the last 2 lines of /etc/ssl/openssl.cnf:

Code: Select all

MinProtocol = TLSv1.2
CipherString = DEFAULT@SECLEVEL=2
with these ones:

Code: Select all

MinProtocol = TLSv1.0
CipherString = DEFAULT@SECLEVEL=1
I hope that this post can be helpful for the community.
Cheers,
Enrico
