- Two routers (one primary and one secondary)
- A modem
- Ethernet cables
- A computer or device for configuration
Additionally, it is a good practice to back up your primary router’s configuration before making any changes.
Method 1: Using a LAN-to-WAN Connection
This is one of the most common methods for connecting two routers. Follow these steps:
Step 1: Connect Your Primary Router
- Connect your modem to the WAN (Internet) port of the primary router using an Ethernet cable.
- Power ON the modem and router, and wait for them to establish a connection.
Step 2: Connect the Second Router
- Using another Ethernet cable, connect one of the LAN ports of the primary router to the WAN port of the secondary router.
- Power ON the secondary router and wait for it to boot up.
Step 3: Configure the Secondary Router
- Access the secondary router’s configuration page by typing its IP address into a web browser (commonly 192.168.1.1 or 192.168.0.1).
- Log in with the credentials (usually found on the router or in its manual).
- Change the Router Mode to DHCP, which will allow it to assign IP addresses to devices connected to it.
- Optionally, you can assign a static IP address that falls outside the primary router’s DHCP range to avoid IP address conflicts.
Method 2: Using a LAN-to-LAN Connection
This method is slightly different but can be just as effective. Here’s how to do it:
Step 1: Connect Your Primary Router
- Similar to the first method, connect the modem to the WAN port of the primary router using an Ethernet cable.
- Power ON the device and allow it to connect.
Step 2: Connect the Routers Together
- Take an Ethernet cable and connect one of the LAN ports on the primary router to one of the LAN ports on the secondary router.
- Power ON the second router.
Step 3: Configure the Secondary Router
- Log into the secondary router’s configuration page using the same approach as before.
- Disable the DHCP server on the secondary router (as the primary router will be responsible for assigning IP addresses).
- Assign a static IP address to the secondary router that is in the same subnet as the primary router but outside of the primary router’s DHCP range, such as 192.168.1.2 (assuming your primary router’s IP is 192.168.1.1).

What equipment do I need to connect two routers to one modem?
To connect two routers to a single modem, you will need several pieces of equipment. Primarily, you will need a modem that supports multiple devices. Most modern cable or DSL modems have at least one Ethernet port for connecting the primary router. You will also need two routers—a primary one that connects directly to the modem and a secondary one that will connect to the primary router. Additionally, you’ll need Ethernet cables to establish reliable connections between the devices.
If you’re planning to set up a more extensive network, you might also consider using a network switch. This device allows you to connect more than two devices to the main network. Lastly, depending on your specific requirements, you may want to have power adapters for each router, especially if they are not placed near power outlets.
Can I connect two routers wirelessly?
Connecting two routers wirelessly is possible, but it typically complicates the setup. The primary router must support bridging or repeater mode to allow for a wireless connection to the secondary router. This method can introduce latency and may lead to reduced network performance compared to a wired connection, as wireless signals are more susceptible to interference and obstacles.
If you decide to go the wireless route, be sure to configure both routers with the same SSID (Wi-Fi name) and password for seamless connectivity. However, for optimal performance and stability, a wired connection is always recommended when connecting two routers.
How do I configure the secondary router?
To configure the secondary router, start by connecting it to the primary router using an Ethernet cable. Access the configuration page of the secondary router by typing its IP address into a web browser. Common default IP addresses are typically found on the device’s label or in the manual. Once you’ve accessed the settings, disable the DHCP server on the secondary router to prevent IP address conflicts with the primary router.
Next, assign a static IP address to the secondary router within the range of the primary router’s IP address. For instance, if your primary router’s IP address is 192.168.1.1, you can set the secondary router to 192.168.1.2. This configuration helps devices connected to either router communicate effectively. Finally, save your settings and reboot the secondary router to complete the setup process.
Will connecting two routers slow down my internet speed?
Generally, connecting two routers will not inherently slow down your internet speed as long as both routers are configured correctly. The overall speed primarily depends on your internet service package and the bandwidth provided by your ISP.
