Перестает работать интернет

[KAKAfon9I]

Я новичек не судите строго)Вообщем проблема в том что после определенного времени работы ubuntu на ней пропадает интернет.Network manager удален и все прописано вручную.Перезапуск сети не приносит успеха да и простая перезагрузка тоже...Сеть появляется только если перезагрузиться на винду а затем опять загрузить ubuntu.Подскажите куда копать.

Предположу, что это ноутбук и предлагаю посмотреть в биосе энергосбережение сетевой карточки.
Ну и диагностику во время пропадания интернета в студию

Пояснить можешь, почему автору нужно сменить маску сети?

Во время пропадания.
ping -c3 шлюз сети
ping -c3 DNS_провайдера
ping -c3 ya.ru
ping -c3 8.8.8.8
nslookup ya.ru DNS_провайдера

сюда можешь не показывать. Это типичная диагностика перед обращением в техническую поддержку.
А сюда dmesg |tail -100 покажи, когда интернета нет. Убyнта устанавливалось через wubi?

[KAKAfon9I]

Ubuntu была установлена через wubi сейчас переустановил обычным способом не через wubi.
До шлюза пинга нет как пропадает интернет...
