Boot time for wi-fi access points from scratch? What are the most instant?

Question

WiFi

For some reason, nowhere and in any reviews is a rather important characteristic of Wi-Fi access points indicated - loading time from scratch. It is clear that you can install UPS and the problem with loading time will disappear, but this is not always possible.
So, question. We need the fastest possible restoration of Wi-Fi coverage after a power surge. Ideally, no more than 10 seconds. What modern access points of the AC standard provide this? Mikrotik? Ubiquity?
As an example, I can cite an old Asus RT-N56U router on Padavan firmware - about 20-30c to boot (appearance of a web interface). Asus RT-AC68U on the default firmware takes a monstrously long time to load, more than a minute, on dd-wrt it is a little better.

Answer 1

I'll tell you this - the repair time for a burned-out access point is from one working day to infinity, so don't do garbage, but organize a normal power supply - via PoE from an uninterruptible power supply.
