Добрый вечер.Помогите пожалуйста в таком вопросе.У меня роутер DSL 2640U работал надежно и безотказно ( примерно 1 месяц) потом в связи с перездом офиса в другое помещение ( также сменился номер АТС но провайдер остался прежним Укртелеком Украина) роутер отказывается поднимать PPPoE соединение.если настраиваю бриджем - то работает( получает доступ в интернет и работает стабильно)а в режиме автоматического подьема PPPoE инета нет(также не загорается индикатор интернета на роутере).Прошил последней прошивкой - не помогло,монтеры проверили линию на АТС - сказали линия отличная( на слух нет помех и наводок)предпологаю проблему на АТС как это доказать?Заранее спасибо.

а я думаю что атс тут ни при чем, иначе и мост не заработал бы. Попробуй аппаратно сбросить модем (кнопкой сзади) и заново настроить.

1. На вкладке Tools > Remote Log > Configure System Log включите лог. После чего приведите лог модема (Status>Log) в момент попытки PPPoE-соединения.
2. Приведите также вывод страницы Status>ADSL.
3. Укажите точную версию прошивки, которой прошит модем.

итак по порядку вот лог попытки соединения

После этой строки больше ничего?



Довольно высокий уровень затухания в линии (Attenuation (dB): 36.0 17.3). Качество телефонной линии (возможно, расстояние до АТС) не позволяет использовать ADSL2+. На вкладке Advanced > ADSL оставьте включенным только G.Dmt Enabled и пронаблюдайте состояние соединения. Можно также позвонить провайдеру и попросить включить режим Interleave и сделать задержку в передаче данных побольше.

вот когда оставил только D.GMT eneble

PPPoE-соединение по-прежнему не устанавливается? В логах ошибки есть?

на вкладке статус вся инфа. Может быть в настройках лога чтото дополнительно надо включить? у меня он сохраняет только ошибки

Прописывали ли Вы какие-нибудь правила IP Filters?
Приведите вывод страницы Home > WAN.

вот страничка HOME > WAN
1/32 UBR pppoe_1_32_1 ppp_1_32_1 PPPoE Enabled

в IP Filters ничего не прописано.
Не моглибы Вы указать рекомендованные параметры телефонной линии?Просто бюро ремонта - говорит линия идеальная.....а хотелосьбы сравнить с рекомендоваными параметрами.

О параметрах линии неплохо расписано в этой статье http://www.adslclub.ru/index.php?mod=adsl&sub=17

так и какое будет решение по моему вопросу?скорее всего отправить роутер на полку и (или ) в мусорную карзину?
