Пропадает интернет через маршрутизатор D-Link DI-804HV

Здравствуйте.
Вообще возникла проблема. Пропадает сигнал интернета каждые 30-40 минут на секунд 10-20, потом сигнал восстанавливается. Маршрутизатор D-Link DI-804 HV.
Сначала думал, что проблема в ДНС, но когда прописал вручную, осталось все как прежде.
Посмотрел в логи роутера увидел такое:

При пропадании интернета логи роутера выдают это:

Подскажите, в чем проблема? Хотелось бы хоть каких-то советов.
