"All my UfiFi installs get CloudKey - done and done.

As for Araknis APs, I find them limited.
Great for basic install, but not much data mining if you want to see user stats, no unified GUI across APs.
No schedules, bandwidth limits, guest portals, etc."

I think Mario is spot on.

"I still don't understand the need for the cloud key. I mean ,I literally don't know what it does. We just Fing the network, open putty, point to cloud, and adopt. "

We have done this for few years and are trying to get away from it AWS or hosted on our server. For us the maintenance of keeping a server updated and running is a PITA. If you are using guest portal or other features it relies on that link to work. If that link/server/controller stops running ever customer on that controller stops working. They have internet access, but guests cannot authenticate i.e. no worky.

The cloud key is stupid easy to adopt and manage remotely. Update is now based on site and not your entire controller... For 79 or so we can put them in and forget about them.
