Eu novo na conexão Ethernet com o meu Linux Mint, WiFi funciona bem. Mas eu encontrei alguns erros. Depois de passar 2 dias pesquisando, não consegui me conectar.

Com "Método" DHCP automático, aqui está a saída de ifconfig

Além disso, o Wire nunca exibe Connected , mas mostra Connecting... .
Em seguida, mudei para Manual com os seguintes detalhes mostrados na imagem em anexo:

Eu então executei o comando pppoeconf e ele foi executado sem erros.
E aqui está a saída de ifconfig

Eu até tentei fazer ping usando o endereço IP do google.com
$ ping 172.217.10.110
connect: Network is unreachable
Atualização:
Isso é útil? depois de sugerido por uma das respostas, tentei

Por favor, deixe-me saber como resolver este problema.
