Connecting 2 routers to 1 modem

by Shawna_75 / January 6, 2018 11:58 PM PST

I apologize if this has already been asked, new to Forum and still learning my way around. I am needing help connecting 2 routers to 1 modem (if its possible). I had my Internet service upgraded today to 400 mbps. They installed a Arris Modem with a Sagemcom router. I purchased a Netgear Orbi in October and it has served me well but dont know if it can handle the speed or if it would be better to use the Sagemcom router the ISP provided. I have tons and tons of devices connected in my home and would really love to use both routers if at all possible but I am absolutely clueless on how to do this or if i can. Can someone help with some thoughts and maybe some guidance on what I need to do or what is best to do in this situation. Id be extremely grateful!! Thank you!

By both do you mean

Both go to the modem? That requires you to work with the ISP and they charge for the option. Most of us will "USE A ROUTER AS A WAP" which is on google results. Most folk will not connect both to the modem because it doubles the monthly bill.

Both devices can be used.

Most modems by default have at least 2 LAN ports so it is possible to connect 2 routers to it. As mentioned since you have tons of devices connected and you would like internet access as well as use both routers, here is what can be done. Use one which is configured by your ISP to connect to the Internet. Use the second one as a LAN. Connect it to the to the first router so it can get access the internet as well.
Internet-> Modem/Router1-> Router2 -> LAN-> All connected devices.

Correction on my last post.

Modem has only one LAN port, not two as mentioned earlier. The second router needs to be configured as a new Wireless repeater/extender.
You need to check if your old router is compatible with the upgraded speed.
