Introduction: Extend Your WiFi Range with a Spare Router

Poor WiFi signal strength is a common frustration. Dead zones in your home can disrupt streaming, video calls, and online gaming. But before investing in a dedicated WiFi extender, consider this: you might already own the perfect solution! This guide shows you how to repurpose an old WiFi router as a powerful WiFi extender, expanding your network's reach and eliminating those annoying dead spots. Using a spare router as an extender is often a cost-effective and surprisingly simple solution.

What You'll Need

Before we begin, gather the following:

An old WiFi router: This will become your extender. Make sure it's compatible with your main router's WiFi standard (e.g., 802.11n, 802.11ac, or 802.11ax/Wi-Fi 6).
An Ethernet cable: This is ideal for a wired connection between your main router and the extender, offering the most stable and reliable performance. If you're going wireless, ensure both routers support WDS (Wireless Distribution System) or similar bridging technology.
Your main router's details: You'll need its WiFi network name (SSID) and password.
A computer or smartphone: To configure your new extender.

Method 1: Wired Connection (Recommended)

This method provides the most stable and fastest extension.

Step 1: Connect Your Extender to Your Main Router

Using the Ethernet cable, connect one end to a LAN port on your main router and the other to a LAN port on your spare router. Do not connect to the WAN (internet) port on the extender.

Step 2: Access Your Extender's Configuration

Find the extender's IP address (usually 192.168.1.1 or 192.168.0.1, but check your router's manual). Open a web browser on your computer, enter the IP address in the address bar, and press Enter. You'll be prompted for a username and password (consult your router's manual if needed).

Step 3: Configure the Extender as an Access Point (AP) Mode

Most routers have an "Access Point" or "AP Mode" setting. This mode disables the extender's DHCP server and allows it to act as an extension of your main network. The exact location of this setting varies depending on the router's firmware. Look for options like "Wireless Mode," "Operation Mode," or "Work Mode."

Step 4: Connect to Your Main Network's SSID and Password

In your extender's configuration, you'll need to provide the SSID (network name) and password of your main WiFi network. This allows the extender to broadcast the same network name and use the same password as your primary router.

Step 5: Save and Reboot

Save the settings and reboot both your main router and the extender. Once they've restarted, you should have an extended WiFi network.

Method 2: Wireless Connection (WDS Bridging)

This method is more convenient, but may be less stable than a wired connection.

Step 1: Enable WDS on Both Routers

Both your main router and extender must support WDS (Wireless Distribution System). Check their respective manuals to learn how to enable this feature. This is often found under settings related to "Wireless," "Security," or "Advanced Settings."

Step 2: Select Your Main Router's SSID

On the extender, select your main router's SSID from the available networks. You'll need to enter your main network's password.

Step 3: Configure the Extender's SSID and Security

In most cases, you'll want the extender to use the same SSID and password as your main router for seamless roaming. However, you can change the SSID and password if you prefer a separate network name for your extended area.

Step 4: Save and Reboot

Save the settings and reboot both routers.

Troubleshooting Tips

Weak Signal: If the extended network is still weak, reposition the extender closer to your main router and in a location with less interference.
Connection Issues: Check all cable connections and ensure both routers are properly configured.
Conflicting SSIDs: Ensure both routers are not using the same SSID and channel.
Firmware Updates: Updating the firmware on both routers can resolve compatibility issues and improve performance.

Conclusion: Expanding Your WiFi Coverage is Easy!

Turning an old WiFi router into an extender is a fantastic way to improve your home's WiFi coverage. While the wired method is recommended for better reliability, the wireless approach offers convenience. By following these steps and troubleshooting tips, you can significantly improve your home's internet access and enjoy a seamless connection throughout your house.
