Ethernet falhou no Realtek RTL8101 / 2 / 6E 14.04 - 15.10

Question

Ok, tentei seguir todos os exemplos que consegui encontrar, mas nada está funcionando. Preciso da tua ajuda. Um dia uma atualização veio e perdi minha ethernet. Uma atualização de versão com falha acabou resultando em uma reinstalação de 15.04, depois eu atualizei para 15.10. Em cada versão eu tentei baixar o atual driver Realtek RTL8101E (eu também tentei r8169 do site realtek). Eu posso ter o módulo r8101 carregado, mas não consigo nem pingar meu roteador com a conexão com fio. Sem fio está sendo executado no driver ath9k. Aqui estão algumas informações detalhadas:

"sudo dhclient eth0" results in bringing up eth0 but there is still no connection however now I get some different results:

Este comando ajudará a repará-lo completamente se você tiver usado softwares de Tethering muitas vezes ou hotspots etc. Eu recebi este comando de outro post. Isso funcionou para mim

Mas primeiro, digite, isso ajudará você a descobrir como seu hardware está registrado em seu sistema. Procure o primeiro no primeiro bloco, por exemplo o meu foi chamado de enp3s0.

Caso contrário, procure pelo último comentário deste artigo erro do driver ethernet Realtek ubuntu 16.04 Nota: Tente este primeiro
