Having weak WiFi signal in parts of your home can be frustrating. While you can buy commercial WiFi extenders, making your own is inexpensive and can be a fun weekend project. With just a few common materials, you can build a simple DIY WiFi extender to boost your wireless network's range and strength.

Why Build Your Own WiFi Extender

There are several advantages to building your own DIY WiFi extender rather than buying a commercial one:

As long as you have some basic electronics skills and tools, building your own WiFi booster is totally doable. Let's look at what's involved.

How a WiFi Range Extender Works

A WiFi extender is sometimes referred to as a wireless repeater. It works by receiving an existing WiFi signal, amplifying it, and then rebroadcasting it on the same wireless network. It's most helpful for extending a network into dead zones or fringe areas.

Key components of a DIY WiFi repeater:

With a strong understanding of what a WiFi repeater aims to achieve, let's look at how to build a simple one ourselves using common hardware.

Hardware Needed for Constructing a DIY Extender

You likely have most of what you need already or can easily and cheaply get the rest. Required components include:

Long-Range WiFi Antennas

WiFi Access Point

Amplifier Circuit (Optional)

Tools Needed

That covers the key components and tools you'll need. You likely have many of those already. Now let's look at how to assemble them into a high-performance DIY WiFi repeater.

Constructing Your Own WiFi Range Extender

With your hardware assembled, constructing your own WiFi signal booster only takes a few hours. Follow these steps:

1. Install OpenWRT Firmware on Router

The first step is to install OpenWRT on your wireless router. This replaces the manufacturer's default firmware with open-source firmware that easily enables repeater capabilities.

2. Configure Router as Repeater

Once OpenWRT is installed, you can easily configure your router as a wireless repeater.

3. Connect Antennas and Amplifier

Next, set up the external antennas and optional signal amplifier circuit.

4. Connect Repeater to Main Router

To complete the project, connect your DIY repeater back to your main WiFi router.

Once connected your extended wireless network is ready to use! Any WiFi device should now be able to connect to the repeater SSID and get boosted range.
