Я не могу подключиться к Ethernet, но могу подключиться к Wi-Fi

Я использую ubuntu 16.04. Вот результат ifconfig :

-> ~$ ifconfig

В Windows я могу подключиться к сети Ethernet, я перезапустил диспетчер сети, работать не будет.

-> ~$ cat /etc/network/interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

После добавления iface eth0 inet dhcp в / etc / network / interfaces и выполнения ifdown -a , команда ifup -a дает:
