Set a 'reserved' ip address in your DHCP (router) server: It will always assign the same IP address to your Pi. It will act the same as a static address. No configuration in the Pi.


You must change the configuration file /etc/networl/interfaces.

for eth0 you must have a row like this one

iface eth0 inet dhcp

change the file, saveit and restart network service:

systemctl daemon-reload

you can renew your ip address with dhclient

Of course you must have root privileges. Use su - root or sudo
