I just want to state that after spending many hours trying to figure out why Fast Transitioning wasn't working on my two AP100C APs is because XG firewall (SFOS 18.5.2 MR-2-Build380) is setting the wrong config option in the the /etc/config/wireless file in openwrt. when looking at the config that is sent to the AP from XG it is setting the 802.11r setting as option dot11r '1' (which is not enabling fast transition AKA wifi roaming). When I changed the incorrect config setting in the etc/config/wireless config file on both of my APs, to option ieee80211r '1' the Fast Transition (wifi roaming) works without issue. Side note both APs are running the 11.0.018 firmware.
Hopefully this is something that the dev team can correct in a future update.
