However, I after some two hours stations deauthenticate with hostapd and they do not authenticate again even when restarted, I need to restart hostapd. I have attached hostapd log file with station trying to reauthenticate after station restart. I have also two hours long strace log, tcpdump, hostapd_cli and iw dev wlan2 station dump. I can put it on the net if anyone would like to check what is going on. Best Regards Marek
