Technology Introduction
Introduction to Broadband Router Technology
A router is a device that forwards data packets from a source to a destination. Routers forward data packets using IP addresses and
not a MAC 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 page, 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 connected to 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 information should be forwarded to and sends
it. If the information is not intended for any 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 specifically to act as a firewall. In most
circumstances, a firewall is used to prevent unauthorized Internet users from accessing private networks or 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
checked against a set of criteria that the administrator configures. If any 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 server. 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.

Section 1 - Product Overview
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 large areas. 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 computers together.
The most common media is CAT5 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 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 ways to configure your network. You may want
to take some time to determine the best network set-up for your needs.
Reset
To reset the system settings to factory defaults, please follow these steps:
1. Leave the device powered on, do not disconnect the power
2. Press the reset button and hold (use a paper-clip)
3. Keep the button pressed about 10 seconds
4. Release the button
The DIR-100 will then automatically reboot itself.

Section 2 - Installation
Installation
Getting Started
Installation Location
The DIR-100 functions as an Ethernet LAN for your home or office use. The Router can be placed on a shelf or desktop and ideally
you should be able to see the LED indicators on the front if you need to view them for troubleshooting. No special wiring or cooling
requirements are needed but when you are ready to place the Router, you must take into account the following guidelines:
• Place the DIR-100 on a flat horizontal plane.
• Keep away from any heating devices.
• Do not place in a dusty or wet environment.
The recommended operational specifications of the DIR-100 are:
Temperature 32o F ~ 131o F
Humidity 5 % ~ 90 %
In addition, remember to turn off the power, remove the power cord from the outlet, and keep your hands dry when you install the
hardware.
Network Settings
To use the DIR-100 correctly, you have to properly configure the network settings of your computers. The default IP address of the DIR-100
is 192.168.0.1, and the default subnet mask is 255.255.255.0. These addresses can be changed as needed, but the default values are
used in this manual. If the TCP/IP environment of your computer has not yet been configured, you can refer to Conguring Your PCs
to Connect to the DIR-100 to configure it.
For example:
1. Configure your computer IP as 192.168.0.3, subnet mask as 255.255.255.0 and gateway as 192.168.0.1
Or more conveniently
2. Configure your computers to obtain TCP/IP settings automatically from the DHCP server feature of the DIR-100
Since the IP address of the DIR-100 is 192.168.0.1, the IP address of your computer must be 192.168.0.X (where “X” is a number between
2 and 254.) Each computer on your network must have a different IP address within that range. The default gateway must be 192.168.0.1

(the IP address of the DIR-100).
Configuration
The DIR-100 provides an embedded Web-based management utility making it operating system independent. You can configure
your DIR-100 through the Netscape Communicator or Internet Explorer browser in MS Windows®, Macintosh, Linux or UNIX based
platforms. All that is needed is a web browser such as Internet Explorer or Netscape Navigator with Java Script enabled.
Log in
Open your web browser and type in the IP address of the DIR-100 into the Location (for Netscape) or Address (for IE) field and
press “Enter.” The default IP address of the DIR-100 is 192.168.0.1
