Starting from 200.8 we have increased the AP support to 128 in a single network (and 2,048 concurrent clients support). As it was baselined using the least common denominator on hardware, so we had decided to remove the support of the Wi-Fi 5 wave 1 APs so we can allow *any* APs to act as the master role. As you may know we have built-in the controller function inside the AP itself so it was a tough decision to say goodbye of our popular R310 starting 200.8 which was on an earlier version of the hardware spec.
