• Edit the “/etc/dhcpcd.conf” file to configure the ethernet interface “eth0” with the nano editor:

**sudo nano /etc/dhcpcd.conf**

• Scroll to the end of the file and add the following lines, making sure to replace the values for “interface”, “ip_address”, “routers” (gateway) and “domain_name_servers” based on your LAN settings:

**#Ethernet static IP configuration
	interface eth0
	static ip_address=192.168.xxx.xxx/24
	static routers=192.168.1.1
	static domain_name_servers=192.168.1.1 8.8.8.8**

• Press the “Ctrl” + “x” key combination, then “y” and <Enter> to confirm writing changes to the file.
• Reboot the Pi using:

sudo reboot
