Два года все работало хорошо.Месяца три назад при входящем и исходящемзвонке начала рваться связь с интернетом.Сначала был dsl-500t.потом 2500u-одинаково.Провода все подключены правильно.Менял даже сплитер.Ничего не помогает.В webplus руками разводят.
Пожалуйста, помогите.Достало уже((

Смените провайдер на "Авангард".

В познании сила!

Проблема должна быть в сплиттере.

Сплитеров уже 3 штуки поменял.Толку никакого.Что еще можно сделать?

Попрлбуйте поменять телефон. Поставьте какой-нибудь простейший аппарат.

Я вообще пробовал его отключать.Тоже самое.
Кстати,у меня параметры линии выдает следующие

Downstream Upstream
SNR Margin (dB): 22.6 11.0
Attenuation (dB): 6.0 4.0


Это хорошо или плохо?

Вот на всякий случай лог

И напишите пожалуйста точные настройки для 2500U в режиме авторизации.

Параметры линии хорошие.

Какой кабель проложен до щитка? В распаячной коробке есть конденсаторы?
