Brain is dead for getting what you need to do right, at the moment. /me looks at Andrew?
DHCP is the routine in the router that hands out the local LAN IP addresses to your kit that connects to it. Probably in a LAN tab or menu entry in the router GUI. (GUI - Graphical use interface - where you do all the setting up). Somewhere around there is also where you will set the fixed IP address for the slave router.
192.168.0.nnn is a subnet
192.168.1.nnn is a different subnet
192.168.10.nnn a third one.
Any subnet must only have one DHCP server. Fairly obviously now you know what it it is - as otherwise one could hand out an address already being used by some kit given that address by the other DHCP. Chaos. The active one needs to be the one in the router that is connected to the phone line.
