About This User’s Guide
This user’s guide provides instructions on how to install the DSL-G604T Wireless ADSL Router and use it to
provide Internet access for an Ethernet or 802.11g/802.11b wireless LAN.
If you are using a computer with a functioning Ethernet port, the quickest and easiest way to set up the
DSL-G604T is to insert the Installation CD into the CD-ROM drive of your computer and follow the instructions
provided in the Quick Installation Guide.
Before You Start
Please read and make sure you understand all the prerequisites for proper installation of your new Router. Have
all the necessary information and equipment on hand before beginning the installation.
Installation Overview
The procedure to install the Router can be described in general terms in the following steps:
1. Gather information and equipment needed to install the device. Before you begin the actual installation
make sure you have all the necessary information and equipment.
2. Install the hardware, connect the cables to the device and connect the power adapter.
3. Check the IP settings on your computer and change them if necessary so the computer can access the
web-based software built into the Router.
4. Use the web-based management software to configure the device to suit the requirements of your ADSL
service and wireless LAN.
The Setup Wizard
Many users will be able to configure all the settings necessary to use the DSL-G604T with the Setup Wizard. For
ADSL connections that use PPPoE or PPPoA connections, the simplest way to setup the DSL-G604T is to use
the Setup Wizard to configure the Internet connection. Once you access the web interface used to configure the

Installation Requirements
In order to establish a connection to the Internet it will be necessary to provide information to the Router that
will be stored in its memory. For some users, only their account information (Username and Password) is
required. For others, various parameters that control and define the Internet connection will be required. You can
print out the two pages below and use the tables to list this information. This way you have a hard copy of all the
information needed to setup the Router. If it is necessary to reconfigure the device, all the necessary information
can be easily accessed. Be sure to keep this information safe and private.
Low Pass Filters
Since ADSL and telephone services share the same copper wiring to carry their respective signals, a filtering
mechanism may be necessary to avoid mutual interference. A low pass filter device can be installed for each
telephone that shares the line with the ADSL line. These filters are easy to install passive devices that connect to
the ADSL device and/or telephone using standard telephone cable. Ask your service provider for more
information about the use of low pass filters with your installation.
Operating Systems
The DSL-G604T uses an HTML-based web interface for setup and management. The web configuration
manager may be accessed using any operating system capable of running web browser software, including
Windows 98 SE, Windows ME, Windows 2000, and Windows XP.
Web Browser
Any common web browser can be used to configure the Router using the web configuration management
software. The program is designed to work best with more recently released browsers such as Opera, Microsoft
Internet Explorer® version 5.0, Netscape Navigator® version 4.7, or later versions. The web browser must have
JavaScript enabled. JavaScript is enabled by default on many browsers. Make sure JavaScript has not been
disabled by other software (such as virus protection or web user security packages) that may be running on your
computer.
Ethernet Port (NIC Adapter)
Any computer that uses the Router must be able to connect to it through the Ethernet port on the Router. This
connection is an Ethernet connection and therefore requires that your computer be equipped with an Ethernet
port as well. Most notebook computers are now sold with an Ethernet port already installed. Likewise, most fully
assembled desktop computers come with an Ethernet NIC adapter as standard equipment. If your computer does
not have an Ethernet port, you must install an Ethernet NIC adapter before you can use the Router. If you must
install an adapter, follow the installation instructions that come with the Ethernet NIC adapter.
Wireless LAN Configuration
Wireless LAN settings for 802.11g and 802.11b wireless operation must be enabled using the Setup Wizard
before it can be configured. Basic wireless settings including the Channel and SSID can be configured through
the Setup Wizard. Advanced wireless security settings can also be configured with the Setup Wizard.
Security for wireless communication can be accomplished in a number of ways. The DSL-G604T supports WEP,
WPA and WPA -PSK.
Additional Software
It may be necessary to install software on your computer that enables the computer to access the Internet.
Additional software must be installed if you are using the device a simple bridge. For a bridged connection, the
information needed to make and maintain the Internet connection is stored on another computer or gateway
device, not in the Router itself.
If your ADSL service is delivered through a PPPoE, PPPoA or Static IP connection, the information needed to
establish and maintain the Internet connection can be stored in the Router. In this case, it is not necessary to

Introduction
This section provides a brief description of the Router, its associated technologies and a list of Router features.
Router Description and Operation
The DSL-G604T Router is designed to provide a simple and cost-effective ADSL Internet connection for a
private Ethernet or 802.11g/802.11b wireless network. The Router combines high-speed ADSL Internet
connection, IP routing for the LAN and wireless connectivity in one package.
The Router is easy to install and use. The DSL-G604T connects to an Ethernet LAN or computers via standard
Ethernet ports. The ADSL connection is made using ordinary telephone line with standard connectors. Multiple
workstations can be networked and connected to the Internet using a single Wide Area Network (WAN)
interface and single global IP address. The advanced security enhancements, packet filtering and port redirection,
can help protect your network from potentially devastating intrusions by malicious agents from outside your
network.
ADSL
Asymmetric Digital Subscriber Line (ADSL) is a broadband network technology that utilizes standard twisted-
pair copper wire telephone lines to enable broadband high-speed digital data transmission and bandwidth hungry
applications for business and residential customers.
ADSL routers and modems provide faster downloads and more reliable connectivity to the user without loss of
quality or disruption of voice/fax telephone capabilities.
ADSL service operates at speeds of up to 8 Mbps downstream and up to 640 Kbps upstream. A secure dedicated
point-to-point connection is established between the user and the central office of the service provider.
802.11g Wireless
The embedded 802.11g wireless access point provides Internet access and connectivity to the Ethernet for
802.11g and 802.11b wireless workstations. IEEE 802.11g is fully compatible with IEEE 802.11b wireless
devices. The 802.11g standard supports data transfer rates of up to 54 Mbps. The Router’s wireless access point
supports common security protocols used for wireless LAN including WEP encryption, 802.1x and WPA.

Router Features
The DSL-G604T Wireless ADSL Router utilizes the latest ADSL enhancements to provide a reliable Internet
portal suitable for most small to medium sized offices. DSL-G604T advantages include:
•802.11g Wireless Access Point – The built-in 802.11g wireless access point connects 802.11g and 802.11b
wireless devices to the Internet and the Ethernet.
•PPP (Point-to-Point Protocol) Security – The DSL-G604T ADSL Router supports PAP (Password
Authentication Protocol) and CHAP (Challenge Handshake Authentication Protocol) for PPP connections.
•DHCP Support – Dynamic Host Configuration Protocol automatically and dynamically assigns al LAN IP
settings to each host on your network. This eliminates the need to reconfigure every host whenever changes
in network topology occur.
•Network Address Translation (NAT) – For small office environments, the DSL-G604T allows multiple
users on the LAN to access the Internet concurrently through a single Internet account. This provides
Internet access to everyone in the office for the price of a single user.
NAT improves network security in effect by hiding the private network behind one global and visible IP
address. NAT address mapping can also be used to link two IP domains via a LAN-to-LAN connection.
•TCP/IP (Transfer Control Protocol/Internet Protocol) – The DSL-G604T supports TCP/IP protocol, the
language used for the Internet. It is compatible with access servers manufactured by major vendors.
•RIP-1/RIP-2 – The DSL-G604T supports both RIP-1 and RIP-2 exchanges with other routers. Using both
versions lets the Router to communicate with all RIP enabled devices.
•Static Routing – This allows you to select a data path to a particular network destination that will remain in
the routing table and never “age out”. If you wish to define a specific route that will always be used for data
traffic from your LAN to a specific destination within your LAN (for example to another router or a server)
or outside your network (to a ISP defined default gateway for instance).
•Default Routing – This allows you to choose a default path for incoming data packets for which the
destination address is unknown. This is particularly useful when if the Router functions as the sole
connection to the Internet.
•ATM (Asynchronous Transfer Mode) – The DSL-G604T supports Bridged Ethernet over ATM
(RFC1483), IP over ATM (RFC1577) and PPP over ATM (RFC 2364).
•Precise ATM Traffic Shaping – Traffic shaping is a method of controlling the flow rate of ATM data cells.
This function helps to establish the Quality of Service for ATM data transfer.
•G.hs (Auto-handshake) – This allows the Router to automatically choose either the G.lite or G.dmt ADSL
connection standards.
•High Performance – Very high rates of data transfer are possible with the Router. Up to eight Mbps
downstream bit rate using the G.dmt standard.
•Full Network Management – The DSL-G604T incorporates SNMP (Simple Network Management
Protocol) support for web-based management and text-based network management via an RS-232 or Telnet
connection.
•Telnet Connection – The Telnet enables a network manager to access the Router’s management software
remotely.
•Easy Installation – The DSL-G604T uses a web-based graphical user interface program for convenient
management access and easy set up. Any common web browser software can be used to manage the Router.

Wireless LAN Basics
Some basic understanding of 802.11b/g wireless technology and terminology is useful when you are setting up
the Router or any wireless access point. If you are not familiar with wireless networks please take a few minutes
to learn the basics.
Radio Transmission
Wireless LAN or WLAN devices use electromagnetic waves within a broad, unlicensed range of the radio
spectrum to transmit and receive radio signals. When a wireless access point is present, it becomes a base station
for the WLAN nodes in its broadcast range. WLAN nodes transmit digital data using FM (frequency
modulation) radio signals. WLAN devices generate a carrier wave and modulate this signal using various
techniques. Digital data is superimposed onto the carrier signal. This radio signal carries data to WLAN devices
within range of the transmitting device. The antennae of WLAN devices listen for and receive the signal. The
signal is demodulated and the transmitted data extracted. The transmission method used by the access point is
called Direct Sequence Spread Spectrum (DSSS) and operates in a range of the radio spectrum between 2.4GHz
and 2.5GHz for transmission. See the technical specifications for more details on wireless operation.
Range
Range should not be a problem in most homes or small offices. If you experience low or no signal strength in
some areas, consider positioning the Router in a location between the WLAN devices that maintains a roughly
equal straight-line distance to all devices that need to access the Router through the wireless interface. Adding
more 802.11g access points to rooms where the signal is weak can improve signal strength. Read the section
about placement of the Router titled Location in the next chapter, Hardware Installation, for more information.
SSID
Wireless networks use an SSID (Service Set Identifier) to allow wireless devices to roam within the range of the
network. Wireless devices that wish to communicate with each other must use the same SSID. Several access
points can be set up using the same SSID so that wireless stations can move from one location to another without
losing connection to the wireless network.
The DSL-G604T operates in Infrastructure mode. It controls network access on the wireless interface in its
broadcast area. It will allow access to the wireless network to devices using the correct SSID after a negotiation
process takes place. By default he DSL-G604T broadcasts its SSID so that any wireless station in range can learn
the SSID and ask permission to associate with it. Many wireless adapters are able to survey or scan the wireless
environment for access points. An access point in Infrastructure mode allows wireless devices to survey that
network and select an access point with which to associate. You may disable SSID broadcasting in the web
manager’s wireless menu.
Wireless Security
Various security options are available on the DSL-G604T including open or WEP, WPA, and WPA-PSK.
Authentication may use an open system or a shared key. For details on these methods and how to use them,
please read the wireless LAN configuration information in chapters 3 (Basic Router Configuration) and 4
(Advanced Router Configuration) below.

About 802.11g Wireless
Today's 11-megabits-per-second 802.11b wireless networks are fine for broadband Internet access (which
typically tops out at about 1 mbps) but rather slow for large internal file transfers or streaming video. However,
54-mbps, corporate-oriented 802.11a is expensive--and because its radio uses the 5-GHz band and 802.11b uses
the 2.4-GHz band, upgrading to an 802.11a network means either scrapping 802.11b gear or buying even-pricier
hardware that can support both standards.
But 802.11g promises the same speed as 802.11a and the ability to coexist with 802.11b equipment on one
network, since it too uses the 2.4-GHz band.
802.11g is an extension to 802.11b, the basis of many wireless LANs in existence today. 802.11g will broaden
802.11b's data rates to 54 Mbps within the 2.4 GHz band using OFDM (orthogonal frequency division
multiplexing) technology. Because of backward compatibility, an 802.11b radio card will interface directly with
an 802.11g access point (and vice versa) at 11 Mbps or lower depending on range. You should be able to
upgrade the newer 802.11b access points to be 802.11g compliant via relatively easy firmware upgrades.
Similar to 802.11b, 802.11g operates in the 2.4GHz band, and the transmitted signal uses approximately 30MHz,
which is one third of the band. This limits the number of non-overlapping 802.11g access points to three, which
is the same as 802.11b.

Hardware Installation
The DSL-G604T maintains three separate interfaces, an Ethernet LAN, a wireless LAN and an ADSL (WAN)
interface. Place the Router in a location where it can be connected to the various devices as well as to a power
source. The Router should not be located where it will be exposed to moisture or excessive heat. Make sure the
cables and power cord are placed safely out of the way so they do not create a tripping hazard. As with any
electrical appliance, observe common sense safety procedures.
The Router can be placed on a shelf or desktop, ideally you should be able to see the LED indicators on the front
if you need to view them for troubleshooting.
Choosing the Best Location for Wireless Operation
Many environmental factors can affect the effective wireless function of the DSL-G604T. If this is your first
time setting up a wireless network device, read and consider the points listed below.
The access point can be placed on a shelf or desktop, ideally you should be able to see the LED indicators on the
front if you need to view them for troubleshooting.
Designed to go up to 100 meters indoors and up to 300 meters outdoors, Wireless LAN lets you access your
network from anywhere you want. However, the number of walls, ceilings, or other objects that the wireless
signals must pass through can limit signal range. Typical ranges vary depending on the types of materials and
background RF noise in your home or business. For optimum range and signal strength, use these basic
guidelines:
1. Keep the number of walls and ceilings to a minimum:
The signal emitted from Wireless LAN devices can penetrate through ceilings and walls. However, each
wall or ceiling can reduce the range of Wireless LAN devices from 1 to 30M. Position your wireless
devices so that the number of walls or ceilings obstructing the signal path is minimized.
2. Consider the direct line between access points and workstations: A wall that is 0.5 meters thick, at a
45-degree angle appears to be almost 1 meter thick. At a 2-degree angle, it is over 14 meters thick. Be
careful to position access points and client adapters so the signal can travel straight through (90º angle)
a wall or ceiling for better reception.
3. Building Materials make a difference: Buildings constructed using metal framing or doors can reduce
effective range of the device. If possible, position wireless devices so that their signal can pass through
drywall or open doorways, avoid positioning them so that their signal must pass through metallic
materials. Poured concrete walls are reinforced with steel while cinderblock walls generally have little
or no structural steel.
4. Position the antennas for best reception. Play around with the antenna position to see if signal
strength improves. Some adapters or access points allow the user to judge the strength of the signal.
5. Keep your product away (at least 1-2 meters) from electrical devices:
Position wireless devices away from electrical devices that generate RF noise such as microwave ovens,
monitors, electric motors, etc.
