When you extend your current network, you may need to add more routers to the existing network. Without knowing how to perform router cascading, you will fail to add an extra router to the network successfully. In this tutorial, you will learn how to connect extra routers to the current network by cascading routers without having any network issues. There are two ways to cascade a router to another router. Before configuring the second router for router cascade, make sure that it is not connected to the main router (where the broadband modem is connected).
LAN to LAN Router Cascading Method
This method is used when you want to use the same network address on devices connected to the second router. Here the second router is acting as a switch to extend your current network.
Many users use this method to cascade a new wireless router with an existing wired router to extend the router 1 to connect other wireless devices and still have the same network addresses assigned by the first router. This method is very popular when a user needs to cascade a wireless router with another existing router in the network. Do not confuse this method with the step to cascade two wireless routers.
WAN to LAN Router Cascade(Method 2)
Before you connect a router to another router in WAN to LAN cascade Method, make sure that both routers have different IP addresses. If both routers have the same IP address, you need to change the IP address of the second router to prevent any conflict. Steps to configure the second router in WAN to LAN cascading method are:
One of the most asked question from my readers is about possible issues with cascading routers from different vendors. There are no issues with cascading routers from different vendors. You won't face any issues with cascading a Linksys router with Belkin router or D-Link router because router cascading is vendor-free.
Different Methods to Cascade Two Routers
- LAN to LAN Router Cascade
Connecting one of the Ethernet ports (LAN ports) of the second Router to one of the Ethernet ports (LAN ports) of the main router. In this method, the devices connected to the second router and the devices connected to the first router are in the same network and can communicate with each other directly. - WAN to LAN Router Cascade
Connecting the Internet port (WAN port) of the second Router to one of the Ethernet ports (LAN ports) of the main router. In this method, we are creating two different networks with different network addresses.

- Connect your computer to the LAN Port of the Router 2
- Log in to Second Router
Access the router’s web-based setup page{Second Router}. To learn how to access the web-based setup page of a router, visit the link below.
How to Find Login Address Of My Router - Change the IP Address of Router 2
When the router’s web-based setup page appears, look for Local IP Address and change it to “192.168.X.Y { Most of the times' router IP address is 192.168.X.1 where X and Y start from 0 to 255 }. We must ensure that Y is a number between 0 to 255 and is out of the DHCP range of router 1.
Eg: Assign IP address 192.168.X.200 (Where X is the same value as in router 1. Eg X value of router 1 with address 192.168.1.5 is 1) to the second router where the IP address of the first router(main router connected to the modem) is 192.168.X.1 - Disable DHCP On Router 2
When the web-based setup page opens, look for DHCP Server and click Disable. Do not forget to save settings. Click Advanced Routing and change Operating Mode to Router.(Depends on the router models and vendors this may change}. - Connect Router 2 to Router 1
Connect LAN Port of Router 1 to LAN Port of Router 2 using an Ethernet cable. Connect a standard Ethernet network cable to one of the numbered Ethernet ports on the main router, where the broadband modem is connected. Then, connect the other end of the Ethernet cable to the Ethernet port of the router that you have just configured.

Before you connect a router to another router in WAN to LAN cascade Method, make sure that both routers have different IP addresses. If both routers have the same IP address, you need to change the IP address of the second router to prevent any conflict. Steps to configure the second router in WAN to LAN cascading method are:
- Make sure Both Routers have Different Network Address
If both routers have the same network address (check the third octet and make sure both routers have different third octet number. Eg: 192.168.1.5 for router 1 and 192.168.2.1 for the second router). If both routers have the same third octet number, proceed to step 2. - Change Third Octet of Router 2 IP Address
Access the second router’s web-based setup page and look for Local IP Address and change it to “192.168.X.1 Where X is any number between 0 to 255 except the number in the first router.[ie: If the IP address of the first router is 192.168.5.1 the X of the second router is any number between 0 to 255 other than 5]. Do not forget to save settings. - Make sure DHCP server on the second router is on
- Connect the Second router to WAN port of the First router
Connect a standard Ethernet network cable to one of the numbered Ethernet ports on the main router, where the broadband modem is connected. Then connect the other end of the Ethernet cable to the Internet port of the router that you have just configured.
