Hi, I got this problem on one of my AP's (I got 10 3662) but this one is like crazy, he always do that and there are always 20 sec between the down and the up time.. I've updated the firmware of all my APs (2.01RC098 03/03/2020) and I have also put default settings like 3 times to get default config and then put mine, or a test config with just an SSID and password, but still the same ...
