That "Could not get PMK" is the reason for the AP to reject the
connection. It looks like you are trying to use EAP-MD5 with WPA and
that is not going to work since EAP-MD5 does not generate any keying
material (which is the reason for the PMK not being available here). You
would need to change the EAP method to something that allows keying
material to be generated, e.g., EAP-TTLS with EAP-MD5 in the tunnel.
