Having reliable and strong WiFi connectivity throughout your home is crucial these days. We rely on WiFi for everything from streaming movies and TV shows to video calls, online gaming, and general web browsing. However, WiFi signals can degrade over distance and be obstructed by walls and other barriers. This often leads to "dead zones" in parts of your home where the WiFi is slow or nonexistent.

The best solution is to install a mesh WiFi system, but these can be expensive. A cheaper and easier alternative is to build your own DIY WiFi range extender to boost your existing router's wireless signal into those dead zones. With the right components and a bit of technical know-how, you can build an extender that will significantly improve your home's WiFi coverage.

What You'll Need

Building a WiFi range extender requires just a few key components:

How to Set Up Your Extender

With your components ready, setting up the extender is straightforward:

1. Place the Extender

Ideally, you'll want the extender placed between your wireless router and the area with bad WiFi coverage. The closer it is to the router, the better signal it will receive. Elevated locations are best to allow wide dispersal of the boosted signal.

2. Connect Extender to Router

There are two options for linking the extender to your router:

3. Configure Extender Settings

Once connected to the router, log into the extender's software interface to complete setup:

4. Connect to the Extended Network

The extender will now be broadcasting your router's WiFi signal under the new SSID you configured. Connect your devices in the problem area to this extended network to benefit from the boosted signal. Expect significantly faster speeds and a more reliable connection.

Optimizing Your Extended Network

To get the best performance from your DIY WiFi extender, keep these tips in mind:

Troubleshooting Connectivity and Speed Issues

If your extended network develops issues, here are some steps to resolve them:


Boosting your home's WiFi coverage with a DIY range extender is fairly cheap and easy. Strategically place the extender, connect it to your router via Ethernet or wireless, configure its settings, and connect your devices to the new extended network. Adjust locations and channels to optimize performance. With this simple upgrade, you can banish WiFi dead zones for good.
