A conexão com fio do Ubuntu 13.04 não está funcionando

Question

Após a atualização para o 13.04, não consigo fazer o trabalho de conexão com fio (a internet sem fio funciona bem). Eu verifiquei nas configurações de conexão que ele deveria se conectar automaticamente.

ifconfig dá:

A única solução que funcionou para mim (que eu encontrei em questões semelhantes às versões anteriores) foi adicionar ao / etc / network / interfaces as seguintes linhas.

auto eth0
iface eth0 inet dhcp

Mas sempre que eu inicializo sem conexão com fio, eu tenho problemas com a configuração da rede e tenho que esperar muito tempo antes que o sistema inicie.

Eu entendo que o problema é com o meu driver e1000e (correto?), mas não tenho certeza do que fazer sobre isso. Eu aprecio todas as sugestões.

    

Answer 1

Tente isso

echo on | sudo tee /sys/class/net/eth0/device/power/control

Isso definitivamente deve resolver todo o problema ... depois de concluído, saia do sudo e puxe para fora, depois conecte novamente o cabo ethernet
