Mainly it boosts the range of existing WiFi and creates a stronger signal in the poor coverage areas. Once it is set up and connected then we can move it as per our requirement where ever we want a better WiFi signal. It helps in extending the home/office network to cover more area. But nowadays newer WiFi Extenders don’t require these. WiFi Extender connects to Wired network through a wired connection may be Ethernet or coaxial cable to connect to the router. That’s why it is also called a WiFi Signal Repeater. This helps to boost the wireless signal strength where the signal strength is weak. It is often referred to as a network repeater. WiFi repeaters are easier to set up and configure because it can be placed anywhere at home, even if there is no wired network port. It is just like a relay system that connects to our WiFi network and rebroadcasts the signal to a larger area of our home/office where we have a poor connection or weak signal. WiFi Repeater connects to the WiFi network wirelessly and re-broadcasts the signal.
