The Wireless N Range Expander is the easiest way to expand wireless coverage in your home or small office. Just put it in between your wireless router and the dead spot in your area that you want to cover. It is designed to "repeat" signals into the far, hard-to-reach areas of your home or office. Eliminating the need to run cables lets you build a wireless network in a most cost effective way. The Wireless-N Range Expander works with most Wireless access points and wireless routers, and is compatible with Wireless-B, G, and N devices. Installation is a snap with push-button setup. Just plug it in and press the button. There is also an easy to use installation wizard for more complicated setups.
