Всем привет! Хочу посоветоваться, что может вызывать постоянные отключения устройств Apple в моей сети. У меня стоит новый Cloud Key Gen 2 Plus и два Unifi AP-AC-Lite.

- Версия Unifi AP-AC Lite: 4.0.21.9965  
- Прошивка Cloud Key: UCKP.apq8053.v0.9.11.24e7935.190409.2343  
- Контроллер Cloud Key: 5.10.23-11668-1  

Настройка очень простая — просто создал беспроводную сеть и сделал 2G и 5G Overrides на каждом AP.

Мой Pixel 3 не отваливается, а вот два айфона постоянно теряют соединение и снова подключаются. Из-за этого сбивается детекция присутствия для домашней автоматизации.

Вот как выглядит журнал событий:

Fast Roaming у меня выключен, мониторинг соединения тоже, пробовал менять DTIM с 1 на 3 — результата нет.  
Также пробовал назначать устройству статический IP — тоже без изменений.  

Я относительно новичок в Ubiquiti и Unifi, буду благодарен за любые советы по устранению этой проблемы!  
Спасибо, Dan
