целый год модем 2640U работал нормально, месяц назад начались проблемы

проблем две:

1) утром после включения модема сразу не поднимается интернет. со второго включения все работает

2) периодически (10-20 раз в день) пропадает интернет и появляется только после перевключения. подозреваю, что обрывается связь со станцией , а модем не модет восстановить PPP соединение

есть версия, что проблема у провайдера, но хотелось бы получить подтверждение у Вас, так как провайдер (Уралсвязьинформ) уверяет что у них все в порядке

логи будут ниже

модем настроен в режиме рутера

согласно ftp://ftp.dlink.ru/pub/ADSL/DSL-2640U/F ... eadme.html у меня DSL-2640U

версия прошивки последняя рекомендованная - http://webdev.dlink.ru/fw/DSL-2640U/V.3 ... 043H00.zip

заранее спасибо!

Здравствуйте,

Что касается первой проблемы, наблюдается нестабильная работа ADSL соединения (рассинхронизация). Попросите провайдера ограничить скорость в профиле порта на DSLAM.
Что касается второй проблемы: данная проблема также связана с рассинхронизацией ADSL соединения, о чем говорит данный кусок лога:

_________________
С уважением, Давыдов Денис.

да, я и сам видел, что пропадало соединение со станцией. однако я не мог понять, почему оно не поднимается после обрыва

попробую попросить провайдера снизить скорость. результат сообщу

спасибо!

Будем ждать вашего ответа.

_________________
С уважением, Гакало Алексей

скорость понизили. также по рекомендации провайдера отключили часть типов модуляции в меню advanced->adsl. оставили только "G.Dmt enabled" и "Etswap Enable" (не уверен в правильном написании последнего)

в результате вторые сутки все работает нормально!

правда мне не совсем понятно что именно помогло. владелец модема боится трогать настройки, чтобы не остаться снова без интернета :о)

всем спасибо!
