Здравствуйте. Провайдер Билайн перешел на "Динамический IP адрес". Роутер разрывает соединение с провайдером, а не продляет соединение, т.е. каждые 10 минут идет переподключение.

Напрямую работает отлично, без каких-либо претензий. Телевидение работает отлично через роутер. Роутер netgear jwnr2010v5 (тестировал) работает без сбоев.

По гарантии сдавал роутер, дефект не выявлен.

Долго и не один раз общались с поддержкой билайн, они не видят проблем. Их оборудование настроено штатно. Массовых обращений нет по этой проблеме. Единственное, что получилось от Билайна узнать, попробовать изменить время запроса на роутере на меньшее или большее время (не знаю, как это сделать).

На данный момент мне вернули L2TP соединение, работает стабильно, но предупредили, что через пару месяцев полностью перейдут на динамический IP, а L2TP отключат.

Лог прикрепляю (а также файлом):
