I can't see my network interfaces in ubuntu 16.04.3

Yesterday my PC connected to the internet; today it doesn't. The command ifconfig -a just shows the loopback interface, and when I checked the file /etc/network/interfaces I only saw this:
auto lo
iface lo
inet loopback
I tried this:
auto enp0s25
iface enp0s25 inet dhcp
/etc/init.d/networking restart
It failed. A reboot did not help. I tried changing the name of the interface to eno1 and eth0 which did not help. Why don't I see the MAC address of my Ethernet interface?
I also tried to set a static IP address like this:
iface enp0s25 inet static
address 192.168.0.100
netmask 255.255.255.0
gateway 192.168.0.1
dns-servers 8.8.8.8 8.8.4.4
I would appreciate if someone could help me.
