If all The APs are R310 or another supported model, you can also migrate the end user to Unleashed which costs nothing. With the R310, you’re limited to a max of 25 APs, 512 users, and all APs must be on the same subnet. Unleashed will give you comparable ZD functionality including mesh, DPSK, captive portal, etc, and it gives you built-in high availability. Using the Unleashed mobile app you or the end user can remotely monitor and manage the network from anywhere.
