I also have this, but only with one device (mobile phone, Mi8 lite [platina]) which hourly drops off my WPA2-EAP RADIUS authed WiFi network. I also see the RETRANSMIT lines in the logread output.
I've already tried setting "wpa_disable_eapol_key_retries" from 1 to 0 but it didn't solve the problem. According to
I'll now try to work around the problem by setting:
option eap_reauth_period '0'
Update: Seems to work since I set it and solves my problem.
