Após atualizar meu dual-boot Windows 10 e Ubuntu 14.04 LTS para 16.04, a conexão com fio parou de funcionar. A opção para Rede Ethernet está em cinza e apenas conexões sem fio estão disponíveis. A conexão Ethernet também não está funcionando no Windows 10. A execução de um diagnóstico no Windows aparece como nenhum cabo Ethernet conectado. Eu tentei o mesmo cabo LAN e configuração no meu laptop e funciona.
Minha configuração é por cabo LAN para um extensor NETGEAR Powerline que está conectado ao meu Superhub da Virgin Media NETGEAR. Funciona perfeitamente com meu laptop.
O comando cat /etc/network/interfaces aparece:

Eu atualizei o driver da placa de rede usando sudo apt-get install r8168-dkms , mas isso não resolveu o problema.
