What is a WiFi Extender

A WiFi extender, or wireless range extender, is a device that repeats the wireless signal from a router to expand its coverage. It works as a bridge, capturing the WiFi signal from the router and rebroadcasting it to areas where the WiFi is weak or nonexistent, improving the performance of the home WiFi. A WiFi extender can be an easy way to get the wireless coverage needed to eliminate dead zones in a home or office. There are different types of WiFi extenders available, including wireless repeaters, WiFi boosters, and wired-wireless network extenders. A wireless repeater catches a wireless signal and rebroadcasts it, giving a stronger signal at the far end. However, using a wireless repeater cuts in half the potential speed of a device’s network connection. A WiFi extender uses both wired and wireless technologies to bring a wireless signal to an area of the home where network coverage has been weak or non-existent. The WiFi extender first uses a wired connection, or wired backhaul, to travel throughout the home, which means that it benefits from the reliability and high speed of cables, instead of relying solely on wireless signals. WiFi extenders are generally easy to set up, and they can be configured to communicate with the main wireless router with little more than the push of a button.
