What is a WiFi extender and how does it work?
A WiFi extender is a device designed to boost the coverage area of your wireless network. It works by receiving the existing WiFi signal from your router and then rebroadcasting it to areas where the signal is weak or non-existent. This helps to eliminate dead zones in your house or office, providing a more reliable connection for your devices.
Installing a WiFi extender is typically straightforward; you plug it into an outlet halfway between your router and the area with poor coverage. Once configured correctly, the extender will enhance the range of your WiFi network, allowing devices in far corners of your home to connect seamlessly to the internet.
