It seems that when I put these options to hostapd.conf it stopped to freeze: wpa_group_rekey=0 wep_rekey_period=0 second one is probably not necessary since I use wpa ? Now, I have also turned off isc-dhcp-server and now modules have static IP I will continue to test this config for the next week I suppose, so I will check hostapd with strace, and or gdb when it freeze. I will try also wifi sniffer, can You recommend something ?
