If you are trying out different functions of your wireless network, you may want to learn how to cascade routers. The best routers, after all, typically allow for the option of cascading. But why cascade routers, what does it do, and how does one do it? Keep reading to find out.


  • Cascading two routers allows for a second wireless router to act as a wireless network extender, helping increase your wireless range and support heavier network traffic.
  • Use the newer of the two routers as your primary router, as this one will be directly connected to the modem via Ethernet cable to the Internet port.
  • Connect your secondary wireless router to a computer to adjust DHCP settings, IP address settings, and more.

Why Cascade Routers?

The main reasons folks look to cascade routers are to increase the overall range of their wireless network and to eliminate dead spots, though in some cases it can even increase speed and overall efficacy, though cascading is not helpful when learning the definition of a guest network on a router.

Insider Tip

Cascading two routers can otherwise be referred to as using one router as a wireless range extender.

How to Cascade Two Routers

The process here will differ slightly according to the make and model of your router so be sure to check the instructions, as performing a cascade incorrectly could lead you to service interruptions, so you’ll be asking why a router is not showing 5G, for instance.


Designate which router will be the primary unit and which be the secondary unit. The primary router will be the one directly connected to the modem. As a general rule of thumb, choose the newer and more advanced router as your primary device.


Plug the secondary router into a computer via Ethernet port or LAN port and access the admin panel or firmware software. This is done by opening up the firmware or by typing in the router’s IP address into a web browser address bar.


Change the secondary router’s IP address via the aforementioned settings pages. It doesn’t really matter what the IP address is, as long as the final digit is different from the final digit of your primary router’s IP address. Confirm the change.


Disable the secondary router’s DHCP settings via the admin panel or firmware. Next, look for a settings page designated for general operation. Set the secondary router as a wireless range extender.


Unplug the secondary router from your computer and plug it into an Ethernet port of your primary router. Your routers are now cascaded, though you should take a bit of time to perform some tests.

This typically involves unplugging the unit and plugging it back in, looking for an Internet connection via the WiFi router. This is the process if you have a single router or a cascade router network.

Cascaded router vs IP passthrough: What’s the difference?

A cascade router is typically used to increase Internet access and the range of a WiFi router. IP passthrough is for assigning unique IP addresses.

How to add a second Linksys router to a network?

You can add a secondary router to a wireless network by following the steps above, whether this secondary router was manufactured by Linksys or by another company.

STAT: The wireless equivalent of cascading is called bridging. This method is officially supported only by selected router models. (source)
