Hi, Thanks for helping me out. As I can imagine that bridge between wlan0 interface and eth0 interface could help for the ft_over_ds=1 setting (keys exchanged over ethernet), I have trouble seeing why hostapd requires a bridge for the ft_over_ds=0, I just hoped that that key exchange could happen over the air, between wlan0 of AP-1 and wlan0 of AP-2. I will try creating wlan0--eth0 bridges on both APs and use ft_over_ds=1 setting.
