How do you daisy chain routers?

Answer 1

Routers perform DHCP, which means the router acts as the "owner" of the network. If a router set it's own IP address to 192.168.1.1, then it will likely assign IPs to computers connected to it in the 192.168.1.x range. If you plug another router into your first router, the second router might have the IP 192.168.2.1, and then assign IPs in the 192.168.2.x range. This is what you want to avoid. Having all your computers on the same 192.168.x network is necessary.

You essentially want to use your second router as a switch. To do this, disable DHCP in the routers admin UI. Then, instead of plugging the source cable (coming from your first router) in the "Uplink" port, plug it into one of the regular 1, 2, 3, 4 etc ports. This will enable your router to pass along IPs from your main router, rather than assign it's own. Plug other devices into 2, 3, 4, etc. You've essentially bridged your routers.
