About This User’s Guide
This user’s guide provides instructions on how to install the DSL-G804V Wireless ADSL Router and use it to
connect a computer or Ethernet LAN to the Internet.
If you are using a computer with a functioning Ethernet port, the quickest and easiest way to set up the DSLG804V 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 beg in the actual installation
make sure you have all the necessary information and equipment.
2. Install the hardware, that is, connect the cables (Ethernet and telephone) 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
account.
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. Yo u 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-G804V 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, Windows NT, Windows 2000, Windows XP and Me.
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 4.5, 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.
v
DSL-G804V Wireless ADSL Router User’s Guide
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 equ ipment. 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 ad apter.
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 CLIP (IPoA) 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
install software on your computer. It may however be necessary to change some settings in the device, including
account information used to identify and verify the connection.
All connections to the Internet require a unique global IP address. For bridged co nnections, th e global IP settings
must reside in a TCP/IP enabled device on the LAN side of the bridge, such as a PC, a server, a gateway device
such as a router or similar firewall hardware. The IP address can be assigned in a number of ways. Your network
service provider will give you instructions about any additional connection software or NIC configuration that
may be required.
About CLIP Connections (RFC 1577)
Classical IP over ATM (CLIP) connections may require global IP settings for the device. Your service provider
will give you IP settings information if needed. Some CLIP connections function like peer-to-peer connections
and therefore do not require IP settings on the WAN interface.

Your Modem supports the following connection protocols:
PPPoE, PPPoA, PPPoA with DHCP, Bridge, and CLIP
(IPoA).
ADSL uses various standardized modulation techniques to
transmit data over the allotted signal frequencies. Some
users may need to change the type of modulation used for
their service. The default DSL modulation (MMODE) used for
the Router automatically detects all types of ADSL
modulation. However, if you are instructed to specify the
modulation type used for the Router, you have three
alternatives: G.LITE, G.DMT and T1.413
This is the method your ADSL service provider will use to
verify your Username and Password when you log on to their
network. Your Modem supports the PAP and CHAP

security features including multiple VPN tunnels
What is ADSL?
Asymmetric Digital Subscriber Line (ADSL) is an access technology that utilizes ordinary copper telephone
lines to enable broadband high-speed digital data transmission and interactive multimedia applications for
business and residential customers.
ADSL greatly increases the signal carrying capacity of copper telephone lines witho ut interfering with regular
telephone services. For the ADSL user, this means faster downloads and more reliable connectivity. ADSL
devices make it possible to enjoy benefits such as high-speed Internet access without experiencing any loss of
quality or disruption of voice/fax telephone capabilities.
ADSL provides a dedicated service over a single telephone line operating at speeds of up to 8 Mbps downstream
and up to 640 Kbps upstream, depending on local telephone line conditions. A secure point-to-point co nnection
is established between the user and the central office of the service provider.
D-Link ADSL devices incorporate the recommendations of the ADSL Forum regarding framing, data format,
and upper layer protocols.

Hardware Installation
The DSL-G804V maintains five separate interfaces, four Ethernet and one ADSL interface. Place the Router in a
location where it can be safely 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 precautions.
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.
Power on Router
CAUTION: The Router must be used with the power adapter included with the device.
To power on the Router:
1. Insert the DC Power Adapter cord into the power receptacle located on the rear panel of the Router and plug
the adapter into a suitable nearby power source.
2. You should see the Power LED indicator light up and remain lit. The Status LED should light solid green
and begin to blink after a few seconds.
3. If the Ethernet port is connected to a working device, check the Ethernet Link/Act LED indicators to make
sure the connection is valid. The Router will attempt to establish the ADSL connection, if the ADSL line is
connected and the Router is properly configured this should light up after several seconds. If this is the first
time installing the device, some settings may need to be changed before the Router can establish a
connection.
Factory Reset Button
The Router may be reset to the original factory default settings by depressing the reset button for a few seconds
while the device is powered on. Use a ballpoint or paperclip to gently push down the reset button. Remember
that this will wipe out any settings stored in flash memory including user account information and LAN IP
settings. The factory default IP address of the Router is 192.168.1.1 and the subnet mask is 255.255.255.0, the
default management Username is admin and the default Password is admin.

Network Connections
Network connections are provid ed through the ADSL por t and the four Ethernet por ts on the back of the Router .
See the Rear Panel diagram above and the illustrations below for examples.
Connect ADSL Line
Use the ADSL cable included with the Router to connect it to a telephone wall socket or receptacle. Plug one end
of the cable into the ADSL port (RJ-11 receptacle) on the rear panel of the Router and insert the other end into
the RJ-11 wall socket. If you are using a low pass filter device, follow the instructions included with the device
or given to you by your service provider. The ADSL connection represents the WAN interface, the connection to
the Internet. It is the physical link to the service provider’s network backbone and ultimately to the Internet.
Connect Router to Ethernet
The Router may be connected to a single computer or Ethernet device through the 10BASE-TX Ethernet port on
the rear panel. Any connection to an Ethernet concentrating device such as a switch or hub must operate at a
speed of 10/100 Mbps only. When connecting the Router to any Ethernet device that is capable of operating at
speeds higher than 10Mbps, be sure that the device has auto-negotiation (NWay) enabled for the connecting port.
Use standard twisted-pair cable with RJ-45 connectors. The RJ-45 port on the Router is a crossed port (MDI-X).
Follow standard Ethernet guidelines when deciding what type of cable to use to make this connection. When
connecting the Router directly to a PC or server use a normal straight-thr ough cable. You should use a crossed
cable when connecting the Router to a normal (MDI-X) port on a switch or hub. Use a normal straight-through
cable when connecting it to an uplink (MDI-II) port on a hub or switch.
The rules governing Ethernet cable lengths apply to the LAN to Router connection. Be sure that the cable
connecting the LAN to the Router does not exceed 100 meters.
Hub or Switch to Router Connection
Connect the Router to an uplink port (MDI-II) on an Ethernet hub or switch with a straight-through cable as
shown in the diagram below:
If you wish to reserve the
uplink port on the switch o
hub for another device,
connect to any on the othe
MDI-X ports (1x, 2x, etc.)
with a crossed cable.

1. Connect to the Router To configure the WAN connection used by the Router it is first necessary to
communicate with the Router through its management interface, which is HTML-based and can be
accessed using a web browser. To access the management software your computer must be able to
“see” the Router. Your computer can see the Router if it is in the same “neighborhood” or subnet as the
Router. This is accomplished by making sure your computer has IP settings that place it in the same
subnet as the Router. The easiest way to make sure your computer has the correct IP settings is to
configure it to use the DHCP server in the Router. The next section describes how to change the IP
configuration for a computer running a Windows operating system to be a DHCP client.
2. Configure the WAN Connection Once your are able to access the configuration software you can
proceed to change the settings required to establish th e ADSL connection and connect to the service
provider’s network. There are different methods used to establish the connection to the service
provider’s network and ultimately to the Internet. You shou ld know what Encapsulation and conn ection
type you are required to use for your ADSL service. It is also possible that you must chang e the PVC
settings used for the ADSL connection. Your service provider should provide all the information you
need to configure the WAN connection.
Configuring IP Settings on Your Computer
In order to configure your system to receive IP settings from the Router it must first have the TCP/IP protocol
installed. If you have an Ethernet port on your computer, it probably already has TCP/IP protocol installed. If
you are using Windows XP the TCP/IP is enabled by default for standard installations. Below is an illustrated
example of how to configure a Windows XP system to automatically obtain IP settings from the Router.
Following this example is a step-by-step description of the procedures used on the other Windows operating
systems to first check if the TCP/IP protocol has been installed; if it is not, instructions are provided for
installing it. Once the protocol has been installed you can configure the system to receive IP settings from the
Router.
For computers running non-Windows operating systems, follow the instructions for your OS that configure the
system to receive an IP address from the Router, that is, configure the system to be a DHCP client.
If you are using this Router to provide Internet access for more than one computer, you
Note
can use these instructions later to change the IP settings for the other computers.
However, you cannot use the same IP address since every computer must have its own
IP address that is unique on the local network.
