De repente, a internet parou de funcionar no meu sistema Ubuntu 13.04. Primeiro eu tentei reiniciar o roteador, mas não funcionou. Então eu tentei internet em WIN 7 está funcionando bem. Mas não está funcionando no Ubuntu, eu tentei ambos LAN / Wifi, mas eles não estão funcionando. Abaixo eu colei todas as informações que eu recolhi:

Não sei se vai funcionar ou não, mas você pode tentar. É seguro, então não precisa se preocupar.

Siga estes passos.

  • Primeiro, faça um backup de /etc/network/interfaces

    sudo cp /etc/network/interfaces /etc/network/interfaces.back
    
  • Abra /etc/network/interfaces por sudo gedit /etc/network/interfaces e substitua o conteúdo por:

    auto eth1
    iface eth1 inet dhcp
    
  • Salve e feche gedit e execute o seguinte comando:

    sudo ifup eth1
    
  • Tente se conectar novamente e tente reiniciar o sistema uma vez.

  • Se não funcionar, então sinto muito! isso não seria sua solução. Substitua seu novo arquivo /etc/network/interfaces pelo antigo: /etc/network/interfaces.back :

    sudo mv /etc/network/interfaces.back /etc/network/interfaces
    

Responda o que acontece.
