Disable the Built-In DHCP Server

By default, the modem router functions as a DHCP server. The modem router assigns IP,
DNS server, and default gateway addresses to all devices connected to the LAN. The
assigned default gateway address is the LAN address of the modem router.
You can use another device on your network as the DHCP server or specify the network
settings of all your computers.
