How to Build a Low Cost WiFi Repeater and Extend Your Wireless Network Range

Having a strong WiFi signal throughout your home is important for seamless Internet connectivity. However, WiFi routers often have limited range, resulting in slow speeds or dropped connections in parts of your home. The good news is that you can build your own WiFi repeater to boost your wireless network's range for a fraction of the cost of commercial repeaters.

What is a WiFi Repeater and How it Works

A WiFi repeater (also known as range extender) is a device that receives an existing WiFi signal, amplifies it and rebroadcasts the boosted signal.

The repeater extends the network coverage area by relaying signals between the router and your devices. It works by receiving wireless signals from your router, amplifying them and transmitting the boosted signals.
