The Belkin N300 extends Wi-Fi range by approximately 5,000 square feet. It works with virtually any router and doesn't require you to reconfigure any of the devices on your wireless networks.
To set up your Belkin N300, first plug it to a socket within the range of your router's Wi-Fi signal, and check for the list of available wireless networks on a Wi-Fi-capable device. Select Belkin.setup from the list, open your web browser, and type "Belkin.range" to enter the setup page. Click Get Started, select your wireless network, and click Next. Enter the password for your wireless network, click Next, and then click Create Extended Network. The extended network should be functional.
