BENEFITS OF DUO
The D-Link® Xtreme N Duo™ Media Router (DIR-855) is the latest addition to the Award-winning Xtreme N product family. The Duo technology in the DIR-855 supports dualband (2.4GHz & 5GHz) wireless signals at the same time. This allows you to check e-mail and browse the Internet using the 2.4GHz band while simultaneously streaming High-Definition (HD) movies and other media on the 5GHz band. The DIR-855 is designed for users looking to get a true HD wireless connection that can handle multiple HD video streams throughout the house, while being backward compatible with your existing 802.11g and 802.11a products.

5GHz TECHNOLOGY
The DIR-855 utilizes the 5GHz band, which is the best technology available for wirelessly streaming multiple HD videos across your network. It achieves this by operating in a clear wireless band to avoid interference that may slow down and limit the range of current wireless technologies like 802.11g**.

SHAREPORT
With SharePort™ technology you can connect a USB printer or storage device to your router and allow users to access them from anywhere on the network. Conveniently turn your existing USB printers and storage devices into network devices for everyone to share.

WHY INTELLIGENT QoS IS BETTER!
With some routers, all wired and wireless traffic, including Voice over IP (VoIP), Video Streaming, Online Gaming, and Web browsing are mixed together into a single data stream. By handling data this way, applications like Streaming Video could pause or delay. With the D-Link Intelligent QoS Prioritization Technology, wired and wireless traffic are analyzed and separated into multiple data streams. These streams are then categorized by sensitivity to delay, so applications like VoIP, Video Streaming, and Online Gaming are given priority over Web browsing. This enables multiple applications like Streaming Video and Gaming to stream smoothly to your TV or PC.

Delivering best-in-class performance, network security, and coverage, the Xtreme N Duo Media Router (DIR-855) is the ideal centerpiece for your wireless network in the home or office.
