Описание проблемы: Несколько раз в день пропадает интернет, пишет, что DNS сервер не отвечает. Лечится перезагрузкой роутера+диагностика неполадок. Причем пока диагностику не проведешь - не заработает =_= (диагностика ничего не находит,просто пишет что всё работает - и всё начинает работать).
Компьютер подключен по проводу, ноутбук и телефон по wi-fi.

Судя по данным журнала
Sep 3 09:56:08 PPP WARNING PPPoE hard line is disconnected, please check the line
Это значит, что разрыв произошёл из-за того, что роутер потерял сигнал через кабель провайдера. Обращаться в поддержку провайдера для проверки кабеля.
И ещё у вас стоит PPPoE и вторичное соединение - динамич. ip.
Поставьте вместо динамич. - отключено.

убрал вторичное подключение, пока уже день вылетов не было. Либо совпадение, либо помогло. Надеюсь на второе.
