300mbps wireless n wifi repeater effectively contains two wireless routers, similar to the wireless router you already have in your home or office. One of these wireless routers picks up the existing WiFi network. It then transfers the signal to the other wireless router, which transmits the boosted signal.A WiFi repeater or extender is used to extend the coverage area of your WiFi network. It works by receiving your existing WiFi signal, amplifying it and then transmitting the boosted signal. With a WiFi repeater you can effectively double the coverage area of your WiFi network - reaching far corners of your home or office, different floors, or even extend coverage to your yard. The WiFi Repeaters are very easy to install. All you have to do is place the repeater in a location that can receive your existing WiFi network, and then attach the power supply. You can then log into the WiFi repeater via your computer, and input the login details and password of your existing WiFi network, to allow the WiFi repeater to connect and extend.
