These are the best AC APs out there

As an aside to that note, they access points will retain any settings sent to them as long as they don't loose power themselves, meaning if the server is rebooted without restarting the management client the APs will continue to work until they them selves are restarted or power-cycled.

These APs work GREAT and are a bargain compared to other enterprise level APs.

So you may also want to invest in a Unifi Security Gateway as well as those don't seem to crash
