A Range Extender is a device that boosts the coverage area of a wireless network, allowing users to connect to the internet from farther away. It works by receiving the existing Wi-Fi signal and amplifying it, effectively extending the range of the network. This is particularly useful in larger homes or offices where the original signal may not reach all areas. These devices are often used in conjunction with routers, such as those made by Netgear or TP-Link. By placing a range extender in a location where the Wi-Fi signal is still strong, users can enjoy a more reliable connection in previously hard-to-reach spots.
