После перепрошивки неожиданно пропадает связь, хотя лампочки dsl и internet горят. Винда7 в евент вьювере говорит вот что - Клиенту не удалось проверить следующие DNS-серверы как активные, которые могут обслуживать клиента. Возможно, серверы временно недоступны или неправильно настроены. 192.168.1.1 (Microsoft-Windows-DNS-Client)

настроил ip в сетевой карте:
ip: 192.168.1.25
маска: 255.255.255.0
шлюз:192.168.1.1
dns:192.168.1.1
альт dns 80.250.64.3

после прописи этих параметров стало реже отключаться, примерно два-три раза в день. помогает только кнопка питания в модеме.
антивирус Аваст.
вот лог модема:

Кстати почему у него 1 января всегда?

Вопрос все еще открыт!

присоеденяюсь к теме
Тоже самое.

Нижайше просим Великую Техподдержку ответить смрадам смертным, ибо мы не грамотные, тупые юзеры впали в немилость несправедливую, направьте нас темных где нам ковырять надо ваш наисветлейший чудо-модем сниспосланный с небес в наши грязные руки и тёмные души!

Укажите, пожалуйста, версию прошивки модема которую Вы используете. Сбрасывали ли Вы настройки в заводские установки после перепрошивки?


1 января в логе потому, что Вы отключали питание модема (часы сбрасываются). А синхронизация времени с NTP-сервером произойдет только после того, как соединение с интернет будет установлено.

BoardID: DSL-2640U
Software Version: RU_1.21
Bootloader (CFE) Version: 1.0.37-12.1
Wireless Driver Version: 4.170.16.0.cpe2.1sd1

2640U/BruC - если точнее. Сброс делал, все как в факе написано.

ответ ждем!

У меня модем 2540u/C, прошивка 1.21. Стал лучше работать с этой прошивкой, но всеравно иногда перестает работать инет, спасает перезагрузка.
