Estou tentando conectar o Ubuntu 14.04 à internet com um cabo ethernet. Eu desliguei o wireless. O cabo funciona com um laptop Windows que estou usando agora. Quando eu conecto o cabo, a conexão com fio 1 aparece, mas o símbolo no canto superior direito da tela continua a abranger as barras como se estivesse tentando estabelecer uma conexão. Às vezes, ele diz "sem fio desconectado". Meu problema, possivelmente, é semelhante a postagem no fórum . Mas não dá uma boa descrição de como configurar graficamente a conexão. Eu incluo abaixo os comandos mais frequentes

Para esclarecer qualquer um dos lados dos tis na minha pasta de código, não há cabo conectado (acima do til) e com cabo abaixo.
Abaixo está a imagem q do que vejo graficamente

O seguinte comando resolveu o problema
echo -e "nameserver 8.8.8.8\nnameserver 8.8.4.4" | sudo tee /etc/resolv.conf
Em seguida, reinicie o network-manager com o seguinte comando
sudo service network-manager restart
Depois, reiniciei o computador para que ele funcionasse.
