Проводная сеть - ничего не показано

Я не вижу информацию о «проводном соединении» при переходе в «Настройки»> «Сеть».

Я вижу беспроводное соединение, но ничего о проводном соединении, даже когда я подключаю соединительный провод Ethernet к разъему порта RJ-45. Нужно ли переустанавливать драйверы или сетевой сервис снова?

Кто-нибудь знает, как это можно решить, пожалуйста? Я использую Ubuntu 18.04.3 LTS, 64-битный.
