Introduction
Congratulations on your purchase of the D-Link Wireless Broadband Router. Your Wireless Broadband Router enables you to share your DSL or Cable Internet connection with computers on your network. This guide will explain the features and functions of the Wireless Broadband Router to help you get the most out of your Internet experience.
D-Link’s DI-714 allows LAN users to share a single Internet Connection while providing the safety and security of port blocking, packet filtering, and a natural firewall. Static address support, integrated DHCP, PPPoE, and device name support will allow it to connect to nearly any broadband provider whether Cable or DSL based, and at the same time simplify local area network settings.
The DI-714 provides two levels of security support. First, it masks local users’ IP addresses from others on the Internet making it much more difficult for a hacker to target a machine on your network. Secondly, it can block and redirect certain ports to limit the services that outside users can access. Specific ports can be opened to ensure that games and other Internet applications will run properly.
The Wireless Broadband Router provides special pass-through support for common VPN implementations. The Virtual Server feature allows you to expose HTTP, FTP, Game Servers and other local services to be accessible to Internet users located outside of the LAN. The User­Definable Application Sensing Tunnel feature allows you to define the attributes to support special applications requiring multiple connections, such as Internet gaming, video conferencing, and Internet telephony. A DMZ setting can be applied to a single client behind the Wireless

Broadband Router to expose it to the Internet and ensure complete Internet application compatibility even if specific ports are not known.
Unlike proxy server or NAT software that requires the software server to remain visible on the Internet, local networked computers are not directly externally visible when using the DI-714. Also the Wireless Broadband Router, like broadband, is always on, removing the need to constantly boot a software server when access is desired from a client.
Integrated DHCP services allow up to 253 users to get their IP address automatically on boot up from the DI-714. Client machines require no software (only the installed NIC card in a wireless network), simply set the Ethernet or wireless adapters to accept a dynamically assigned IP address and reboot. Each time they are powered up the DI-714 will recognize them and set their IP address to instantly connect them to the LAN.

Introduction to Broadband Router Technology
A router is a device that forwards data packets from a source to a destination. Routers work on the OSI (Open System Interconnection) Layer 3, which forwards data packets using IP addresses and not a MAC (Media Access Control) address. A router will forward data from the Internet to a particular computer on your LAN.
The information that makes up the Internet gets moved around using routers. When you click on a link on a web p age, you send a request to a server to show you the next page. The information that is sent and received from your computer is moved from your computer to the server using routers. A router also determines the best route that your information should follow to ensure that the information is delivered properly.
A router controls the amount of data that is sent through your network by eliminating information that should not be there. This provides security for the computers behind your router because computers from the outside cannot access or send information directly to any computer on your network. The router determines which computer the in formation should be forwarded to and sends it. If the information is not intended for an y computer on your network, the data is discarded. This keeps any unwanted or harmful information from accessing or damaging your network.
Introduction to Firewalls
A firewall is a device that sits between your computer and the Internet that prevents unauthorized access to or from your network. A firewall can be a computer using firewall software or a special piece of hardware built
7
specifically to act as a firew all. In most circumstances, a firewall is used to prevent unauthorized Internet users from accessing private networks such as corporate LAN’s and Intranets.
A firewall watches all of the information moving to and from your network and analyzes each piece of data. Each piece of data is check ed against a set of criteria that the admini strator confi gures. If an y data does not meet the criteria, that data is blocked and discarded. If the data meets the criteria, the data is passed through. This method is called packet filtering.
A firewall can also run specific security functions based on the type of application or type of port that is being used. For example, a firewall can be configured to work with an FTP or Telnet serv er. Or a firewall can be configured to work with specific UDP or TCP ports to allow certain applications or games to work properly over the Internet.
Introduction to Local Area Networking
Local Area Networking (LAN) is the term used when connecting several computers together over a small area such as a building or group of buildings. LAN’s can be connected over a large area. A collection of LAN’s connected over a large area is called a Wide Area Network (WAN).
A LAN consists of multiple computers connected to each other. There are many types of media that can connect comput ers together. The most common media is CAT5 (Ethernet) cable; UTP or STP twisted pair wire. On the other hand, wireless networks do not use wires; instead they communicate over radio waves. Each computer must have a Network Interface Card (NIC), which communicates the data between computers. A NIC is usually a 10Mbps network card, or 10/100Mbps network card, or
8
a wireless network card.
Most networks use hardware devices such as hubs or switches that each cable can be connected to in order to continue the connection between computers. A hub simply takes any data arriving through each port and forwards the data to all other ports. A switch is more sophisticated, in that a switch can determine the destination port for a specific piece of data. A switch minimizes network traffic overhead and speeds up the communication over a network.
Networks take some time in order to plan and implement correctly. There are many types of scenarios to consider which could affect the operability of a network.
Introduction to V irtual Private Networking
Virtual Private Networking (VPN) uses a publicl y wired network (the Internet) to securely connect two different networks as if they were the same network. For example, an employee can access the corporate network from home using VPN, allowing the employee to access files and printers. Here are several different implementations of VPN that can be used.
Point-to-Point Tunneling Protocol (PPTP)
PPTP uses proprietary means of connecting two private networks over the Internet. PP TP is a way of s ecuring the information that i s com municat ed between networks. PPTP secures information by encrypting the data inside of a data packet.
9
IP Security (IPSec)
IPSec provides a more secure network-to-network connection across the Internet or a Wide Area Network (WAN). IPSec encrypts all communication between the client and server whereas PP TP only encrypts the data packets.
Both of these VPN implementations are used because there is not a standard for VPN server software. Becaus e of this, each ISP or business can implement its own VPN network making interoperability a challenge.
Introduction to Wireless Networking
D-Link wireless products are based on industry standards to provide easy- to- use and compatible high-speed wireless connectivity within your home or business. Strictly adhering to IEEE 802.11b the D-Link Air wireless family of products will allow you to access the data you want, when and where you want it. No longer will you be tethered to a workstation or forced to run new wiring. You will be able to enjoy the freedom that wireless networking delivers.
Standards Based Technology
Based on IEEE 802.11b, D-Link Air wireless products can throughput data up to 11 Megabits per second. This means you will be able to transfer large files quickly or even watch a movie in MPEG format over your network without noticeable delays. This technology works by using multiple frequencies in the 2.4GHz range utilizing Direct Sequence Spread Spectrum (DSSS) technology. D-Link Air products will automatically sense the best possible connection speed to ensure th e greatest speed and range possible with the technology.
10
Installation Considerations
Designed to go up to 300 feet indoors and up to 900 feet outdoors, D­Link Air lets you access your network from virtually anywhere you want. Keep in mind, however, that the number of walls, ceilings or other objects that the wireless signals must pass thru will limit range. Typical ranges vary depending on the types of materials and background RF noise may be evident in your home or business. The key to maximizing range is to follow these basic principles:
1. Keep the number of walls and ceilings to a minimum - Each wall or
ceiling can reduce your D-Link Air Wireless products range from 3-90 feet. Position your Access Points(base stations in a wireless network), Routers, and Computers so that the number of walls or ceilings is minimized.
2. Be aware of the direct l ine betw een Access Points, Wireless Broadband
Routers, and Computers - A wall that is 1 foot thick, at a 45 degree angle appears to be almost 3 feet thick. At a 2 degree angle it looks over 42 feet thick! Try to make sure that the AP and Adapters are positioned so that the signal will travel straight through a wall or ceiling for better reception.
3. Building Materials make a difference - A solid metal door or aluminum
studs may have a negative effect on range. Again, try to position Access Points, Routers, and Computers so that the signal passes through drywall or open doorways and not other materials.
4. Make sure that the antenna is positioned for best reception by using the
software signal strength tools included with your product.
5. Keep your product at least 3-6 feet away from electrical devices that
generate RF noise, like microwaves, Monitors, electric motors, etc.
11
For the average American multiple bedroom home, range should not be a problem. If you experience low or no signal strength in areas of your home that you wish to access, consider positioning the Access Point in a location directly between the Routers and/or Computers that will be connected. Additional Access Points can be connected to provide better coverage in rooms where the signal does not appear as strong as desired.
