A Wi-Fi extender is a device that boosts the range of your wireless internet connection. It works by receiving the existing Wi-Fi signal from your router and amplifying it, allowing you to access the internet in areas of your home or office that may have weak or no signal. This is especially useful in larger spaces or buildings with thick walls. Setting up a Wi-Fi extender is usually straightforward. You simply plug it into a power outlet within the range of your router, connect it to your network, and it will start broadcasting a stronger signal. This helps eliminate dead zones and improves overall connectivity.
