Cascaded Router Network Address

AT&T customers reported problems with their cascaded router network addresses. This is probably due to improper setup. Before we can properly set up a cascaded router networking network, we must first understand what this type of network is.

It’s also a benefit to understand how it works, what DHCP is and what a subnet are, as well as how to set up a cascaded router address. You’ll likely be able to resolve any problems regarding the cascaded router address after reading this article.

What is a Cascaded Router Network and How Does It Work?

Cascaded router networks are networks where multiple routers are connected to one another.

When we need to make more connections, to increase the range of our Wi Fi, or to reduce network traffic, we connect multiple routers together.

If you don’t want your router to be thrown away when you upgrade and you still want to increase your wireless signal range, cascading a router is an option. However, it is important to understand DHCP and subnets.

Dynamic Host Configuration Protocol

The DHCP protocol manages IP address assignment and communication between clients and servers in a network. The client is the device using the services.

The router is the host. We get IP address assignment and the service to route an internet connection. Clients are devices that use this service. our laptops, smartphones, smart TVs, etc.

To avoid conflict between routers, cascading routers requires that there be a DHCP server on each router. It should be the router connected to the internet.


A subnetwork can be described as a logical network within the original network. Multiple logical subdivisions can be created in our network. This can help reduce the distance between devices.

Most organizations use subnetting to divide the IP network into smaller, more efficient logical networks. This reduces traffic and speeds up the network’s speed because data doesn’t need to travel on unnecessary routes.

Cascading routers in the Network

It functions just like any other network. There are more routers on the network, which can make the network work better. Let’s now get to the configuration. Learn how to cascade routers, and how to setup an Access Point.

Cascading routers

Cascade routers can be done in two ways. You can use an Ethernet cable to connect a LAN (Local Area Network), to LAN connection, or an internet connection to cascade routers from LAN to Wide Area Network (Wide Area Network).

Let’s take a look at each step:

If you have an old router and a new router, the new router should be used as your primary router. Turn on the secondary router, and then connect it with an Ethernet cable to a computer or laptop. In the address bar of your browser, type in the IP address for your router.

After you have entered the router settings, you can change the IP address for the secondary router. Locate the LocalIP Address line, and modify the last digit to make it different than the IP address from the primary router. E.g. E.g.

You must disable DHCP server as the primary router has it enabled. This can cause conflict in communications. Next, change the operation mode of the secondary router to a wireless extender and connect it with the primary router. It should work flawlessly.

  • Internet connection – There is a slight distinction in the configuration when you want the internet port to link the second router to the primary router. Just change the last digit in the IP Address on your secondary router.

Go to the secondary router’s website interface and locate the LocalIP Address line. Change the next-to last digit to one that is different from the one on your primary router. E.g. E.g.

After that, connect one end of your Ethernet cable to the Internet port and the other into the any port of the primary router. You now have a cascaded router system.

Setup of Access Point

It is very simple to set up. It only takes a little tweaking. You will still need a primary router and secondary router. It is easiest to use both routers on the same network by activating the AP mode (Access Point) on the secondary router.

The Access Point mode is available on newer routers. All we have to do now is activate it. You should activate the Access Point mode on most routers.

  1. You can access the secondary router’s web portal by entering the IP address in the address bar of the browser. Then, log in using your credentials.
  2. Choose the section or tab you need. It’s most likely located in the Advanced tab under your router’s settings.
  3. Choose Advanced settings or Advanced configuration to locate Wireless settings.
  4. After clicking on it, locate the line that says Enable AP Mode.
  5. You’ll be able to assign an IP address to your AP router using the DHCP function on the primary router.

Turning a router into a Access Point will turn off the DHCP. The subnet IP addresses will remain the same.

Last Thoughts

You now know the basics of DHCP and subnets. It is important to disable DHCP on your secondary router. This will prevent any conflict between them. One router can be used as an Access Point, or as a wireless range extender.

You don’t need to worry about errors in the cascaded router address. Some routers are not intended to be used as a secondary or access point.
