Ubuntu 20.4 Проводная сеть для настольных компьютеров невостребованных/Установка отсутствует

Новое в Ubuntu, linux (как и в моей первой установке было 3 дня назад). Имел он работает на проводном подключении сначала, но затем установил несколько обновлений системы, а затем мои проводные настройки исчезли. Я просмотрел этот сайт и еще несколько раз посмотрел на очень похожие проблемы, но, учитывая уникальную природу каждой машины, я не чувствовал себя комфортно двигаясь вперед с каким-либо конкретным вариантом, не получив больше экспертных заключений. Теперь моя ethernet сеть UNCLAIMED. У меня есть lshw -C сеть, ip a и lspci -k считывания, но, пожалуйста, дайте мне знать, если мне понадобится больше.

sudo modprobe r8168 привели к восстановлению соединения и теперь настройки проводного соединения вернулись. Обращаем ваше внимание, что ваша помощь будет вам очень признательна.

Internet работа и настройки, восстановленные после modprobe r8168, modprobe r8169 не имели очевидного эффекта.
