Two routers on one network netgear setup
I currently have a RBR50 with two satellites connected to a Charter/Spectrum Arris cable modem and would like to make a second network with a separate router and am not sure how to go about it.
From what I understand I could connect a new router to the cable modem and then connect the RBR50 with a wire to the new router and make the RBR50 an extension to the new router, all on one network? Can each router be its own network connected to the modem? Would they need to each connect to a switch and then to the modem, or something else? Thanks for any help.

Having two routers on the same network can cause problems. This would be a double NAT condition which isn't recommended. https://kb.netgear.com/30186/What-is-Double-NAT
You can, however connect either router system to the modem and use the main host routers DMZ for the 2nd router behind the 1st router. The routers have to be on different sub nets, so 1st one can be on 192.168.1.1 while the 2nd needs to be on 192.168.2.1, or .2 being any number between .2 to .254.

Really a modem, and not a gateway/modem+router? An actual model
number would be reassuring.> [...] would like to make a second network with a separate router [...]
Why? What is the actual problem which you are trying to solve?

number, and look for Documentation. Get the User Manual. Look for "Use
the Router as a WiFi Access Point".> [...] Can each router be its own network connected to the modem? [...]
Not exactly.> [...] Would they need to each connect to a switch and then to the

Typical consumer cable-TV Internet service would give you one
external/public IP address, so you can connect only one device to your
modem. Typically, that one device would be a NAT router, which would
allow you to connect multiple devices to the NAT router, whose NAT
features would let them share that one external/public IP address.If you connect multiple devices (through a switch) to the modem, then
I'd expect your ISP to issue your one external/public IP address to the
first device which requests one, and then to ignore any other devices
connected to the modem+switch. Not what you want.
It is possible to cascade multiple NAT routers, and create multiple
LAN subnets ("networks"), but this (double NAT) adds some limitations on
what can be done on the inner router's LAN subnet, and requires some
special configuration (typically adding a static route) on the outer
router, so that devices on the outer router's LAN subnet can communicate
with devices on the inner router's LAN subnet.Whether it makes any sense to do that depends on what you're actually
trying to do.Thanks for the info. The Modem is a Arris TM1602A connected to Charter/Spectrum Ulta service and is connecting at around 400 mbps.
What I'm trying to do is split my house so that one level has it's own router and network and the second level has it's own router and network. Then each person can control their own router, password, and the devices attached to them.
I have a new person moving in and they requested a seprate network with the modem in his area. They do an online live podcast and say "they use alot of bandwith" and wanted to make sure they can control/reset when needed. I'm not famillair with exactly how much they would use. We both stream all of our tv services, four pc's would be in use, plus tablets, Ring, Samsung Smartthings, Amazon cloud cams (4), etc.
The cable modem would be in his area/floor level and he plans on attaching his router to the modem. In this case I would run an ethernet cable to my Orbi for my devices... If we do this I think your are saying I change my Orbi to an access point and let his be the NAT router. Or, if I knew what I was doing, I'd create a static route on his NAT router and make a subnet for my Orbi?
Hope all of this helps explain what I'm trying to do. Any additional help/insite would be great. Thanks.
If you need two separate networks, you can have them, use of the DMZ on the primary host router would need to be used for the 2ndary router...
