Networking - Ethernet não está sendo detectada - Ubuntu 16.10

Question

Eu tentei mudar o endereço ipv6 do meu sistema seguindo o comando - enp3s0 é o nome do meu sistema que eu tenho feito ifconfig antes de começar a mudar o endereço.

sudo -s
nano /etc/network/interfaces
    ###Start IPV6 static configuration
    iface enp3s0 inet6 static
    address 2607:f0d0:2001:000a:0000:0000:0000:0010
    netmask 64
    gateway 2607:f0d0:2001:0001:0000:0000:0000:0001
    ###End IPV6 configuration 
Save and Close
/etc/init.d/networking restart

Também experimentou estes comandos -

service network-manager restart

reiniciar a rede de serviços

Mas depois disso quando faço ifconfig a ethernet não está detectando. Na execução ifconfig abaixo é a saída -

Depois de desfazer as alterações, começou a ser detectado -
