For a small network I ordered 3 WAC720. I will use the ensemble mode. I need roaming, (I understood roaming is better with controller but no controller there), I've read fast roaming 802.11r available with CLI, ok, I also understood that fast roaming 802.11r is not as good as the seemless roaming of the controller.
My questions are about channel selection:
Is it better to let it be automatic for the 3 WAC720s or select channels manually?
Will the APs automaticaly take different channels and will they consider bands used by other networks in the building (not managed by me)?
