2 routers. Can't attache the cable modem to the new Netgear

Question

I just purchased a RS300. After unplugging the ethernet cable from my old router (the cable that goes to the modem) and into the RS300 I could not get an internet connection. If I keep the old router in place an attached to the modem then attach the RS300 to the switch that is attached to the old router the internet works fine.

Does the provider (spectrum) need to assign an IP or something to the RS300?

The old router and the new router are on different networks right now due to the DHCP setting I am using.

I had considered dual routers as well with the goal of adding security for my LAN by isolating Some WiFi devices more effectively than using a guest or iot specific SSID. Advice with this idea is welcome as well.

I would return the RS to place of purchase and get another to try. The router should connect to the modem and after a power cycle of the modem, the RS should get internet services with the modem or behind a primary router.

The modem is one supplied by Spectrum (service provider). There aren't any identifiable markings on it. The Modem does work fine with the Asus router.

I tried both both the GUI and a web browser.

When the Netgear is attached to the LAN port it constantly looses it's connection to the internet. I'm beginning to wonder if the Netgear router is defective. No connection at all to the when attached directly to the modem.

What Firmware version is currently loaded?Can you take a picture of the modem and posted please? Back ethernet ports please.Be sure your using a good quality LAN cable between the modem and router. CAT6A STP is recommended.
&nbsp;
Has a power off for 1 minute then back ON with the ISP modem and router been performed?Be sure to restart your network in this sequence:Turn off and unplug modem.Turn off router and computers.Plug in and turn on modem. Wait 2 minutes for it to connect.Turn on the router and wait 2 minutes for it to connect.Turn on computers and rest of network.
&nbsp;
Be aware that most ISP modems only support having 1 router connected, thus you can't have two routers connected.

Thank you for your reply.I understand - I'm not very skilled in this type of thing.It's modem only no Router or LAN ports.I have an Ethernet switch attached to the LAN port of the Asus router. The Netgear is attached to one of the switches LAN ports.&nbsp;The WiFi client looses connection to the Netgear. It will connect initially but fails within a few seconds.Sometimes the Internet light on the Netgear stays on (connected) other times it drops the internet connection (indicating no connection)&nbsp;Only one pic allowed at a time right now. Let me know if you need another of the front of the modem.The additional 'thin wire" you see is for voice. I'm sure you knew that though.&nbsp;

So if you power OFF the modem, then disconnect the ASUS router from the modem and connect the RS router to the modem, power ON the modem then power ON the RS, Does the RS then work?

I believe that's a base modem Hitron modem.&nbsp;
