Не удается подключиться к Интернету с помощью проводного соединения

Я не могу заставить свой Ethernet-разъем работать, чтобы я мог подключиться к Интернету. Ubuntu 20.04.1 LTS. Wi-Fi подключение к тому же модему работает. Когда я подключаю кабель к Ethernet-порту своего компьютера, индикатор Ethernet загорается зеленым светом, поэтому проблема, похоже, связана с программным обеспечением, а не с оборудованием.


Команда sudo pppoeconf

возвращает следующую ошибку

Извините, я просканировал 2 интерфейса, но концентратор доступа вашего провайдера не ответил. Пожалуйста, проверьте вашу сеть и кабели модема. Другой причиной сбоя сканирования может быть другой запущенный процесс pppoe, который управляет модемом.

Я проверил, и pppoe установлен

Package: pppoeconf
Status: install ok installed

Я набрал sudo poff dsl-provider, и он сказал

/usr/bin/poff: No pppd is running.  None stopped.
