How Do WiFi Extenders Work?
WiFi extenders work by acting as a relay between your router and the devices that are out of range of your main WiFi network. They receive the signal from your router, amplify it, and then rebroadcast the signal. This allows devices that are too far from the router to connect to the internet through the extender, effectively extending the coverage area of your WiFi network. WiFi extenders can be wired or wireless, with wireless extenders being the most common type. They are easy to set up and can be placed in areas where the WiFi signal from the router is weak, thus improving overall network performance.
The process of setting up a WiFi extender typically involves connecting it to your router, either wirelessly or through an Ethernet cable, and then configuring it to match your network’s settings. Once set up, the extender will rebroadcast your WiFi signal, creating a second network that mirrors your original one. Devices can then connect to either the original network or the extended network, depending on which signal is stronger. WiFi extenders are particularly useful in large homes, offices, or areas with many obstacles that can weaken WiFi signals, such as thick walls or floors.
