A Wi-Fi extender is a device that helps improve the coverage of a wireless network. It works by receiving the existing Wi-Fi signal from a router and amplifying it, allowing the signal to reach areas in your home or office that may have weak or no connectivity. 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 can enhance your internet experience by reducing dead zones and improving connection speeds in hard-to-reach areas.
