Читал массу топиков где просят помоч с ошибкой когда падает скорость или изчезат, сопровождаясь dnsprobe[529]: dns query failed.
Все отвечают что можем переключается на альтернативный днс сервер и т.п. но КАК РЕШИТЬ ПРОБЛЕММУ ТАК НИКТО И НЕ СКАЗАЛ. Конкретно как? поменять прошивку не помогает, это пишет каждый, дело точно не в прове, потому как жалуются почти все у кого такой же модем и разные провы. С прошлым модемом у меня никакких проблемм небыло. Может дать кто нить адыкватный ответ или нет на самом то деле...

На мой взгляд великовато затухание в вашей линии. Нужна ли вам модуляция ADSL2+? Если понизите например до G.Dmt соединение будет устойчивее. Узнайте у провайдера адреса двух наиболее стабильно работающих DNS-серверов и пропишите вручную.

такая же проблема - последняя прошивка. 2540U

я так понимаю объём лога ограничен? Потому как не передёргивал машинку уже 24 часа.

это на последней прошивке J.

будем надеяться


хотя закрадывается ещё одно нехорошее подозрение, всё это происходит с вечера субботы по сей момент - вечер воскресенья.
линии УТК наверное не очень загружены, возможно в этом всё дело?
Посмотрим что будет завтра в понедельник

Присоединяюсь к вопросу, пару дней назад начались проблемы, постоянно пропадает интернет.



Подскажите что делать

после нескольких дней тестов можно сказать проблем не было
прилагаю последний лог. что интересно - dns query failed всё же проскакивает, не часто и без повторов. Видимо железка сама поднимается. Default Gateway прописан так - ppp_1_32_1 видимо в этом дело?
