Description
The D-Link Xtreme N Gigabit Router (DIR-655) is a draft 802.11n compliant device that delivers up to 14x faster speeds and 6x farther range than 802.11g while staying backward compatible with 802.11g and 802.11b devices. Connect the Xtreme N Gigabit Router to a cable or DSL modem and provide high-speed Internet access to multiple computers, game consoles, and media players. Create a secure wireless network to share photos, files, music, videos, printers, and network storage. Powered by Xtreme N technology and equipped with three external antennas, this router provides superior wireless coverage for larger homes and offices, or for users running bandwidth-intensive applications. The DIR-655 also includes a 4-port 10/100/1000 Gigabit switch that connects Gigabit wired devices for enjoying lag-free network gaming and faster file transfers.
With some routers, all wired and wireless traffic, including VoIP, Video Streaming, Online Gaming, and Web browsing are mixed together into a single data stream. By handling data this way, applications like video streaming could pause or delay. With D-Link's Intelligent QoS Technology, wired and wireless traffic is 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 to stream smoothly to your TV or PC.
The Xtreme N Gigabit Router supports the latest wireless security features to help prevent unauthorized access, be it from over a wireless network or from the Internet. Support for WEP, WPA, and WPA2 standards ensure that you will be able to use the best possible encryption regardless of your client devices. In addition, this Xtreme N router utilizes Dual Active Firewalls (SPI and NAT) to prevent potential attacks from across the Internet.
Delivering best-in-class performance, network security, and coverage, the Xtreme N Gigabit Router (DIR-655) is the ideal centerpiece for your wireless network in the home or office.

Jargon
ADSL
(Asymmetric Digital Subscriber Loop). High speed Internet access using the telephone line. It uses line-adaptive modulation and provides data speeds from 384kbps to 1.5 Mbps (upstream and downstream speeds are usually different). Unlike the dial up, it doesn't block the telephone line.
Bandwidth
The capacity of any single channel of the system to transmit data.
Menu/BIOS Driven
Refers to the type of controls on some equipment. The user will be offered an on screen menu display of major categories such as Computer, Video, Audio, Display, Options. After selecting one, you will get another menu of choices with items like brightness, contrast, etc. after select one of these and you can then adjust the settings.
Data Rate
The rate or speed at which data is transmitted, usually stated in bits per second or Baud
Firewall
Computer hardware and/or software that limits access to a computer over a network or from an outside source. Used to prevent computer hackers from getting into a company's computer systems.
Hz, (KHz, MHz)
Hertz or (Kilohertz or Megahertz). Cycles per second. (Kilo = 1,000, Mega = 1 million). These terms are used to express the frequency of an electrical signal.
Computer In(put) - Out(put)
Input - Typical labeling of connector on a projector or panel where the cable from your computer plugs in.
Typical labelling of connector on a projector or panel where the cable to your computer monitor is connected. This is not available on all projectors and is not usually needed when using a laptop.
Interface
To connect normally incompatible components so that the signal from one is readable by the second.
IR communication standard
A standard for wireless communicating with peripherals (printers wireless keyboards, pointing devices) and a computer. This feature is becoming common on laptop computers.
Integrated Services Digital Network (ISDN)
Standard digital service capability that includes one or more circuit-switched communication channels capable of carrying digital voice, data, or image signals, a packet-switched channel for out-of-band signaling and control, plus a collection of standard and optional features that support information productivity for the user providing higher-speed Internet access than analogue systems.
LAN
Acronym for Local Area Network; the local area typically being an office building or technology campus.
LAN is short for Local Area Nwtwork. As its name would suggest this is a network of computers local to a room, building or small complex of buildings.
Mbps
(Millions of bits per second) It is a measure of bandwidth. A unit of information transfer rate. While an ethernet connection can run at 10 Mbps the average household modem still runs at 56.6 kbps (kilobits per second).
Network
Connecting two or more computers and/or net workable devices for data sharing or for remote control of devices.
Ethernet
Ethernet is the usual method of connecting computers together in a network or connecting a computer to a broadband internet service provider. Ethernet requires a cable for connection, unlike wireless technology.
Parallel
A method of transmitting several bits of data simultaneously through a communications channel.
PPTP / VPN
Point-to-Point Tunneling Protocol (PPTP) is a protocol (set of communication rules) that allows corporations to extend their own corporate network through private "tunnels" over the public Internet. Effectively, a corporation uses a wide-area network as a single large local area network. A company no longer needs to lease its own lines for wide-area communication but can securely use the public networks. This kind of interconnection is known as a virtual private network (VPN).
Routing Protocol
A set of rules defining the way router machines find the way that packets containing information have to follow to reach intended destination.
SCSI
Small Computer Systems Interface, pronounced "scussy". A device independent interface used for a wide range of peripherals.
TCP/IP
The Transmission Control Protocol (TCP) on top of the Internet Protocol (IP). These protocols were developed by DARPA to enable communication between different types of computers and computer networks. The Internet Protocol is a connectionless protocol which provides packet routing. TCP is connection-oriented and provides reliable communication and multiplexing.
Routing Protocol
A set of rules defining the way router machines find the way that packets containing information have to follow to reach intended destination.
USB
Acronym for Universal Serial Bus; a peripheral connection interface for low-speed devices notable for it's hot-swap ability.
WCDMA
WCDMA is Wideband CDMA. This is the technology for wideband wireless access supporting 3G cell phone services, and allows very high-speed multimedia services like wireless Internet access and videoconferencing.
Wi-Fi
Wi-fi is a wireless alternative to ethernet for networking. It provides similar data transfer speeds to ethernet without relying on cables. It does require you to be within range of a wireless access point.
