Мосты настроены одинаково, два из них работают без нареканий, два других периодически теряют связь точки доступа со станцией, от пары минут до пары часов. в логах станций вижу следующие сообщения

Подскажите, пожалуйста, с чем могут быть связаны эти пропадания связи, и как это исправить.
Спасибо

Установите явным образом на АП и станции фиксированную частоту, не 2,437
Что с мощностями и уровнями сигнала, скрин?
