WPA - AP association Issue

Hi Bryan,

All the APs have different SSID. I have give the specific TLS CCMP CONF file path in .config. I have annexed the CONF file for your perusal.

I have activated the PKCS engine at /usr/lib/pkcs11/libcoolkeypk11.so with engine = 1. Is that required for TLS CCMP association?

I am currently trying the settings at WPA
=============
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
eapol_version=1
ap_scan=2
fast_reauth=1
pkcs11_engine_path=/usr/lib/libcoolkeypk11.so

network={
        ssid="SEMCO_AP"
        proto=WPA
        pairwise=CCMP
        auth_alg=OPEN
        key_mgmt=WPA-EAP
        group=CCMP
        engine=1
        mode=0
        eap=tls
        ca_cert="/usr/bin/CA/ca-cert.pem"
        client_cert="/usr/bin/CA/ca-cert.pem"
        private_key="/usr/bin/CA/private/ca-key.pem"
}

AP Settings are as follows - Scanned Information

=============

Still the issue is the same. Now especially after the .config change, association has become difficult. I have rteid many combinations of the CONF file settings.

Looking forward to your inputs
Thanks
