When the Netgear wireless range extender is installed with home Wi-Fi router, it receives the weak Wi-Fi signals from our existing Wi-Fi router and expand those signals by increasing their signal strength. It means, if our router is only able to send Wi-Fi signals up to midpoint inside our home then, the Netgear wireless range extender will receive hat weak signal and will boost or amplify that signal so, it could reach around every corner inside our home. http://wifirouterextendersetup.net/
