See detail @ http://www.amazon.com/gp/product/B000H96IN2?&tag=cybermday-20 The Wireless-N Gigabit Router with Storage Link is really four devices in one box. First, theres the Wireless Access Point, which lets you connect to the network without wires. Theres also a built-in 4-port full-duplex 10/100/1000 Switch to connect your wired-Ethernet devices together at up to gigabit speeds. The Router function ties it all together and lets your whole network share a high-speed cable or DSL Internet connection. Weve also included a Storage Link that lets you easily add gigabytes of storage space onto your network using readily available USB 2.0 hard drives -- or plug in a USB flash disk for a convenient way to access your portable data files. The built-in Media Server streams music, video, and photos from the attached storage device to any UPnP compatible media adapter.
