How To Connect Multiple Routers To One Modem?

In today’s world, internet connectivity plays a vital role in completing daily tasks, managing businesses, and staying connected with the world. With multiple devices being used simultaneously in households and offices, the need for stronger and faster internet connectivity has become imperative. It can be frustrating when the signal strength of a single router does not reach all corners of a large house or office. In such cases, connecting multiple routers to one modem can provide more robust and reliable internet connectivity.

Connecting multiple routers to one modem is not a difficult task, and with a few simple steps, it can provide coverage to all areas of a house or office. However, it is essential to understand the necessary configuration and setup procedures to ensure seamless and uninterrupted connectivity across devices. In this article, we will guide you through the process of how to connect multiple routers to one modem, including details on different connection methods and tips to help you extend coverage to all areas of your space.

How to Connect Multiple Routers to One Modem?

Connecting multiple routers to one modem requires a specific setup in order to prevent network issues such as IP address conflicts or degraded connection quality. Here are the steps to follow to connect multiple routers to one modem:

1. Determine how many additional routers you need to connect based on the size of your home or office and the number of devices you have.
2. Set up the main router by plugging it directly into the modem with an Ethernet cable. This will establish your main internet connection.
3. Configure the settings of the main router by logging into its administrative interface through a web browser. This often involves entering the router’s IP address or website address.
4. Enable “DHCP” or “Dynamic IP Address” on the main router to automatically assign addresses to connected devices.
5. Connect an Ethernet cable from the LAN port on the main router to the WAN port of the additional router you want to connect.
6. Log into the administrative interface of the additional router through a web browser and configure its settings. Disable the DHCP and configure its IP address range either to a static IP address or to another dynamic IP address range which is different from the main router’s IP address range.
7. Connect any devices to the additional router via Ethernet or Wi-Fi as necessary.

Repeat steps 5-7 for each additional router you need to connect.

Note: In this setup, the additional routers will function as access points and will not perform routing functions. It is recommended to turn off the DHCP function on the additional routers to avoid IP address conflicts between the multiple routers.


1. How many routers can be connected to one modem?
There is no specific limit set on the number of routers that can be connected to one modem, but it’s better to limit to a reasonable number depending on the internet usage and network architecture.

2. What type of connection is required to connect multiple routers to one modem?
You need an Ethernet cable to connect the modem to the router’s WAN port. You can then connect the additional routers with Ethernet cables or through wireless access points.

3. How do I access the settings of the additional routers connected to the modem?
You can access the settings of the additional routers by entering their IP addresses in your browser. The IP address can be found on the router’s label or manual.

4. What is the recommended way to connect multiple routers to one modem?
The recommended way is to use the primary router to handle the network traffic and connect the additional routers in bridge mode. This way, they will act as access points and extend the network coverage.

5. Do I need to configure each router separately to connect to the modem?
Yes, you need to configure each router separately. You can set a unique IP address to each router to avoid conflicts, configure the DHCP settings, and set the SSID and password for the additional routers.


In summary, connecting multiple routers to one modem can be a tricky process, but following the steps we’ve outlined can make it much easier. It’s important to carefully consider your needs and choose the appropriate equipment, such as switches or access points, to ensure that your network functions smoothly and efficiently. By doing your research and taking the time to set everything up correctly, you’ll be able to enjoy a robust and reliable home network that can support all your devices and meet your internet needs. Good luck and happy networking!
