Two Routers on One Modem
Are you wondering if you can connect two routers to one modem? Read on to find out if it's possible and how to do it

Are you wondering if you can have two routers on one modem? The answer is yes, and in this article, we will explore the benefits of having a dual router setup and how to properly connect two routers to a single modem.

In today’s world, the internet has become an integral part of our lives. It’s hard to imagine a day without being connected to the world wide web. However, when it comes to setting up a home network, many people wonder if they can have two routers on one modem. The answer is yes, it is possible, and in this article, we’ll explore how to do it.

Can I Have Two Routers on One Modem?

The answer is YES

First, let’s get this question out of the way. Can you have two routers on one modem? The answer is yes, you can. There are a few ways to do it, and we’ll explore them in the following sections.

Setting up Two Routers on One Modem – Step-by-Step Guide

Here’s a step-by-step guide on how to set up two routers on one modem:

Step 1: Check the Compatibility of the Modem

Before you start setting up your home network, you need to make sure your modem is compatible with two routers. Check the modem’s documentation or contact the manufacturer to find out.

Step 2: Connect the First Router

The first step is to connect the first router to the modem. To do this, you need to plug an Ethernet cable into the modem’s LAN port and connect the other end to the router’s WAN port.

Step 3: Configure the First Router

Next, you need to configure the first router. You can do this by logging into the router’s web interface using your computer’s web browser. Enter the router’s IP address, which is usually printed on the router or found in the manual.

Step 4: Disable DHCP on the First Router

Once you’re logged into the first router’s web interface, you need to disable DHCP. DHCP is a protocol that assigns IP addresses to devices on your network. Since you’ll be adding another router, you don’t want both routers assigning IP addresses.

Step 5: Connect the Second Router

Now it’s time to connect the second router. You can do this by plugging an Ethernet cable into the first router’s LAN port and connecting the other end to the second router’s WAN port.

Step 6: Configure the Second Router

After connecting the second router, you need to configure it. To do this, you’ll need to log into the second router’s web interface and configure it to use a different IP address range than the first router. For example, if the first router uses the 192.168.1.x range, you can configure the second router to use the 192.168.2.x range.

Step 7: Disable DHCP on the Second Router

Finally, you need to disable DHCP on the second router to prevent conflicts with the first router. Once you’ve done this, your two routers should be connected to your modem, and your home network should be up and running.

Understanding the difference between modems and routers


A router is a device that helps distribute an internet connection to multiple devices within a network. It acts as a traffic controller, directing data packets to their intended destinations and making sure that communication between devices is seamless. The router also helps protect your network from unauthorized access by assigning unique IP addresses to each device and implementing firewalls.

There are several types of routers, including wireless routers and wired routers. Wireless routers are the most common and use Wi-Fi technology to broadcast a signal that can be picked up by any device within range. Wired routers use Ethernet cables to connect devices to the network.


A modem is a device that connects your home network to the internet service provider (ISP). The modem takes the signal from your ISP and converts it into a form that can be used by your network devices. The modem also does the opposite, converting data from your network devices into a form that can be transmitted over the internet.

There are two main types of modems: cable modems and DSL modems. Cable modems use a coaxial cable to connect to the ISP, while DSL modems use a phone line.


Can I have two routers on one modem with Wi-Fi?

Yes, you can have two routers on one modem with Wi-Fi. The steps to set it up are the same as those described above.

Can I have two routers on one modem and have them share the same SSID?

Yes, it is possible to have two routers on one modem and have them share the same SSID. However, it’s not recommended as it can cause interference and other network issues.

What is the benefit of having two routers on one modem?

The primary benefit of having two routers on one modem is to increase network coverage and reduce congestion. If you have a large home or office space, one router may not be enough to provide adequate coverage for all areas. By adding a second router, you can extend the range of your network and ensure that all devices can connect to the internet without any issues. Additionally, having two routers can help distribute network traffic, reducing the load on a single router and improving overall network performance.

Can I have more than two routers on one modem?

While it is technically possible to connect more than two routers to one modem, it’s not recommended. Adding additional routers can cause network conflicts and other issues that can be difficult to troubleshoot. It’s best to stick with two routers or invest in a more robust networking solution if you need more coverage.

Will having two routers on one modem affect my internet speed?

Adding a second router to your network should not affect your internet speed as long as the routers are properly configured. However, if you have multiple devices connected to the network and are using bandwidth-intensive activities like streaming video or playing online games, you may notice a decrease in speed. This is because the additional devices are using up more bandwidth, not because of the routers themselves.


In conclusion, having two routers on one modem is possible and can be a great way to extend your network coverage and improve performance. While it may seem daunting at first, the process of setting up two routers on one modem is relatively straightforward, and there are plenty of guides and resources available online to help you through the process. Remember to check the compatibility of your modem, configure each router properly, and disable DHCP to avoid conflicts. With a little bit of patience and know-how, you’ll be enjoying a faster and more reliable home network in no time.
