Eu instalei dois sistemas operacionais na minha máquina, um é o Ubuntu 16.04 e outro é o Windows7. No Windows7, ele pode acessar a rede IPv6, mas no Ubuntu 16.04, ele falha. Meu computador funcionou bem com o IPv6 no passado, tem um endereço IPv6 global e meu roteador suporta rede IPv6.
A seguir estão algumas configurações do meu sistema operacional. Qualquer conselho e sugestão serão muito apreciados.
