Changing IP address from STATIC back to DHCP

Hey Community,
Simple question here I hope. I am running windows 10. I couldn’t access my Cloud “My Book Live” on the network when I changed to windows 10. I now know there are issues. Someone said to change its settings from DHCP to STATIC IP address. I did that. Now I cannot access the drive even through a browser IP address. How do I change it back to DHCP.
Cheers in advance.

Hold down reset button for 10 seconds.
