Ethernet não detectada no Ubuntu 16.04 LTS

0

Eu sou novo no Linux. Não consigo obter uma conexão LAN no Ubuntu 16.04 LTS. Ele costumava trabalhar no Windows 7.

Aqui está o resultado de if config -a

Eu realmente não sei como interpretar esses resultados em termos de solução de problemas, mas agradeço qualquer ajuda que você possa fornecer.

Atualizar

Sinto muito pela pobre explicação. O Ubuntu não está detectando o fato de estar conectado (por exemplo, "Wire Unplugged"). As luzes da porta ethernet estão apagadas.

Aqui está a saída de dmesg | grep -e e100 -e enp

É detectado. É enp0s25. Você simplesmente não tem um endereço IP. Procure em Configurações - > Rede - > Com fio e ligue o dhcp
