NanoStation Loco M2 теряет проводное соединение под нагрузкой

[floop]

WDS мост из двух M2. Пока не пользуюсь - всё хорошо. Но если начинает активная передача данных (не обязательно большой трафик), может выбить на одной точке проводное соединение. Пока не перезагрузишь - не поднимается.

Настроил ватчдог, который перезагружает точку. Связь восстанавливается.

 

раскопал вот такой лог. Может кто сталкивался? Это аппаратное?

[hRUst]

Аппаратная проблема, наверное, оперативка.

[floop]

Поменял точки с инжекторами местами и ролями.

Проблемная точка стала на новом месте отваливаться. Но теперь доступна мне по беспроводной связи.

Вижу как TX на проводном соединении показывает 0. Связь с удаленным хостом теряется.

Взял другой инжектор питания, валялся какой-то старый. Пробую нагружать - пока не пропадает.

Посмотрим

 

UPD: Всё-таки вылетела

 

Снизил Tx power до 19 dBm, наблюдаю дальше.

 

upd: повторяется
