Yeah just a guess, your logs point to auth issue. This posting suggests perhaps saying “no certificates” instead of “dont-require-certificates” but I didn’t study it: http://forum.mikrotik.com/t/eap-tls-wireless-authentication-why-a-mikrotik-station-cannot-connect-to-a-mikrotik-ap/147954/1
You also might try “auto” instead of specify the frequency and/or be NOT set a channel size, but that be the end of my guesses - but logs point to something in EAP.
