Добрый день.
Имеется модем DSL-500T, прошивка V2.01B01T01.RU.20060620, к можему подключен коммутатор DGS-1005D. к нему 3 компа. Все это дело работает 7 дней в неделю, 24 часа в сутки и активно пользует инет. Интернет - стрим.

Почти каждый день в 22:30 инет пропадает. Пропадает иногда на пару секунд. иногда на пару минут. иногда на полчаса. Обычно полднимается сразу, но если нет, то зачастую лечится перетыканием блока питания.

В чем может быть проблема?

Все связано с регламентными работами на стороне Стрима (раз в сутки принудительно рвется PPP сессия).

А почему тогда модем не всегда восстанавливает связь? Буквально вчера инета не было полчаса.а после вытыкания/втыкания блока питания модема он появился.

После разрыва подключения модем предпринимает несколько попыток соединения, после чего (зависит от временного интервала) его нужно перегружать по питанию либо из WEB интерфейса.
Это будет исправлено в следующей прошивке, где можно будет указать временное значение KeepAlive и MaxFail (количество попыток аутентификации).

Понял, спасибо. Ждем следующей прошивки.
