What is DHCP and why it is used?

Dynamic Host Configuration Protocol (DHCP) is a network management protocol used to automate the process of configuring devices on IP networks, thus allowing them to use network services such as DNS, NTP, and any communication protocol based on UDP or TCP.

DHCP means dynamic host configuration protocol; it hands out IP addresses for devices in your network. Unless you are going to configure each device manually, or you have a second DHCP server you should leave this option on.

What happens if I disable DHCP?

You'll hit major issues if you have 2 devices on the same LAN with the same IP address, and if they are the internet gateway, you LAN won't work. Realistically you should only ever have one DHCP server in one Lan, so 2nd router configured as a Wi-Fi hot-spot is OK.

When should I disable DHCP?
