How to configure LAN-WAN to create 2 independent networks

Hi.

I happen to purchase a router for my small home and office network. I did not know at that time that my modem is also a router.

It is a modem/router. If I plug both devices with each other, only one of my computers can go online.

I want to use the functionalities of my modem/router and also the new router.

I don't know how to configure.

Your help is highly appreciated!

How to configure LAN-WAN to create 2 independent networks

When you are planning to connect a router with another router, then you are Cascading them. You have to make sure make sure that both have routers have different IP addresses before you connect a router to another router. This is required because prevent conflict IP address conflicts. There are two ways to cascade a router to another router:

1. LAN to WAN – this is done by connecting the cable from the modem/router to the Internet port (WAN port) of the second router.

When cascading from LAN to WAN, your routers will be independent from each other. The DHCP server of the secondary router is enabled.  When your devices are connected this way, computers connected to the primary router will not be able to share files with computers to connected to the secondary router.

2. LAN to LAN – this is done by connecting both of your routers via Ethernet ports (LAN ports).

When cascading from LAN to LAN, your routers will be dependent of each other. The DHCP server of the secondary router is DISABLED. Computers connected to the primary router will be able to share files with computers connected to the secondary router.

In as far as your concern is, I would suggest that you consider connecting your devices using LAN to WAN.

I get the general idea. So I can't share files from my modem/router to my router if I configure it following the LAN to WAN method? That's exactly what I need. I don't want computers who are connected to my secondary router messing up with computers that are connected to my primary router.

Hi Pearl,

LAN-WAN is the best solution for you knowing that you wish to create 2 independent networks working separately with each other.

Just don't forget to change the IP address of the third octet of the secondary router to avoid the IP address conflict as stated by Rey and of course, do not forget to plug the cable from the modem to the Internet port of your secondary router.

For example, if your secondary router has an IP address of 192.168.1.1, you may change it to a 192.168.2.1.

Okay. I think I can do that. By the way, both of my routers happen to have wireless capabilities. Do I have to change anything in the wireless to keep their wireless from interfering with each other?

@Eloisa, thanks for adding up to the solution provided. @Pearl, to eliminate wireless interference, you should assign specific wireless channel to both routers or you may also set their channel width or Radio Band modes to Auto.

Doing that would allow the router to choose the strongest channel for you.
