ЛОЛ, опять тоже самое - недопустимый адрес, и смена айпишника, видать Авангард жестко издевается над пользователями, буду звонить сново)))

жесть, они еще хуже сделали, теперь точно каждые 30 секунд вылеты, там хоть часик просидел без вылетов.

quod erat demonstrandum

методом научного тыка я понял (как мне кажется), что виноват не Авангард а все же модем, т.к. при отключении линии в настройках так же пишеться что аренда получена на 30 секунд, видать действительно модем что-то не держит.

кстати по поводу какого-то буфера, действительно, когда инет подключен, никакой смены айпишника не происходит, как только появляется нагрузка на сеть происходит обрыв.

Я даже теряюсь, ругаться жёстко или попробовать поставить другой момед да не париться... А этот - продать, благо на халяву дали...

1. DSL-2300U является устройством, работающим по технологии ZIPB.
Другими словами, данное устройство отдает компьютеру по DHCP те параметры, которые получает в результате PPPoE соединения.
Это происходит каждые 30 секунд, при этом PPPoE соединение остается активным и компьютер каждые 30 секунд получает тот же самый IP адрес.

2. По поводу обрывов WAN соединения:
Назначьте компьютеру статический IP адрес, например 192.168.1.2
В настройках DSL-2300U включите лог устройства: Tools > Remote Log > Configure System Log
Log: enable
Log level: debugging
Display level: debugging
Mode: local

нажмите кнопку Apply.

Перенастройте сетевой интерфейс на использование протокола DHCP.
После разрыва соединения, снова назначте сетевому интерфейсу компьютера IP адрес 192.168.1.2, войдите в настройки DSL-2300U и приведите здесь строки системного лога: Status > Log.

To All

В Ваших выводах лога видно, что PPP соединение успешно устанавливается, после чего модем должен отдавать компьютеру по DHCP настройки IP, полученные в результате PPPoE соединения.
Соответственно, для этого сетевой интерфейс компьютера следует настроить на использование DHCP протокола.

_________________
С уважением, Давыдов Денис.

Я, может, чего-то не понимаю... но... оно сразу не настроено? То, что в состоянии подключения написано, что сетевой адрес "Получен по DHCP" - это не показатель?
И, извиняюсь за дурацкий вопрос... как это сделать? =)

Извените, но если я бы не настроил компьютер на использование DHCP протокола, то у меня не было бы интернета как такового, т.к. провайдер предоставляет динамический IP адрес. Поэтому Ваш ответ мне кажется бесмысленным.

dzeaman, такое ощущение что нас оставили с нашей проблемой, и видимо сотрудникам D-Link нет времени разбираться с этими проблемами. Придется сдавать модем и покупать что-то иное =)

Давыдов Денис,

Вы так и не ответили на вопрос - почему все же происходит обрыв соединения, очень хотелось бы узнать.
