How to Build a DIY WiFi Range Extender for Your Home Network

Having reliable WiFi coverage throughout your home is extremely convenient. But WiFi signals can weaken over distance and be blocked by walls and other obstacles. If you have areas in your home with poor WiFi reception, a simple solution is to build your own DIY WiFi range extender.

A WiFi range extender works by picking up your existing WiFi signal, amplifying it, and re-broadcasting the boosted signal. This effectively increases the overall reach and strength of your home's WiFi network. The great news is that with the right hardware, you can build an effective WiFi range extender yourself for under $50.

How to Assemble the Extender

Follow these steps to assemble your DIY WiFi extender:

1. Update Router Firmware

First, make sure the firmware is updated on both the main router and the second router you'll use for extending. Refer to the user manual or contact the manufacturer for details on checking for and installing the latest firmware version.

2. Configure Main Router as Access Point

Log into your main wireless router's admin interface and navigate to the wireless settings. Enable bridging, repeating, or wireless client mode. This allows your main router to function strictly as an access point.

3. Connect Routers and Power On

Connect an Ethernet cable between your main router and second router. Make sure both routers are powered on. The second router should automatically connect to the main router as a wireless client and obtain an IP address.

4. Configure Extender Router

Log into the admin interface of the second router using its default LAN IP address. Navigate to the wireless settings and configure it for wireless bridging, repeating, or AP mode. Enable the same SSID, encryption type, and WiFi password as your main router.

5. Optional: Connect External Antenna

For a stronger signal, you can connect a high-gain antenna to the port on the back of the second router. Position the antenna for optimal reception.

6. Place Extender and Test

Place the extender router in the area with poor WiFi coverage and connect it to power. On your devices, connect to the same WiFi network name as your main router. Walk around and test to confirm the extended coverage!
