Я использую Ubuntu и Windows 10 с двойной загрузкой. при загрузке Ubuntu Ethernet говорит, что он подключен, но не может получить доступ к Интернету. Но я могу получить доступ к Интернету через 15-30 минут, если в это время я не касаюсь своего компьютера. почему эта проблема?

В вашем журнале я вижу, что ipv6 тоже настроен

Jul 17 10:56:41 ninja-desktop avahi-daemon[593]: Joining mDNS multicast group on interface eth0.IPv6 with address fe80::eea8:6bff:fe70:9564.

Можно ли изменить настройки ipv6 на сетевой карте на Метод: игнорировать и посмотреть, работает ли он?

enter image description here

Еще одна вещь, которую тоже нужно проверить - это dnsmasq. Можете ли вы проверить, установлен ли dnsmasq, и удалить его.

Используйте следующую команду

sudo apt-get remove dnsmasq

Я нашел это решение на ubuntuforums .

Вам необходимо проверить настройки DNS вашей сети. Зайдите в Сеть -> Настройки -> Настройки IPV4 -> Дополнительные настройки DNS добавьте DNS-адрес, предоставленный поставщиком услуг, перезапустите браузер и проверьте.
