Chapter 1 Introduction
DHN-120 Installation Guide and Networking Basics
The D-Link DHN-120 is ideal for the small office or home office
environment. The DHN-120 enables you to add your computer to a network.
After completing the steps in this manual, you will have the ability to share
information and resources -such as files and printers -and take full advantage
of a "connected" environment for work and play!
The DHN-120 comes with drivers for the most popular operating systems and
can be integrated into a larger network. This Quick Starter Guide is designed
to help you install the DHN-120 and connect the computer to a network
running Windows 98 or Windows 2000.
The HomePNA standard allows you to connect computers and devices at
speeds up to 10 Mbps. The DHN-120 is based on the newest HomePNA 2.0
standard. Older Network Cards, based on HomePNA 1.0, support speeds up
to 1 Mbps. The DHN-120 is backwards compatible with HomePNA 1.0
products as well.
This Quick Starter Guide will take you through the steps of planning your
network, installing the network hardware and software, and setting up
Windows properly to use basic networking functions like printer and file
sharing and playing network games. Take a moment to read through this
manual and familiarize yourself with the steps necessary to complete the
installation process. The entire process should take from one to two hours of
your time. But, you should also give yourself some time to play with your
new network!

Chapter 2 Installing Adapters and Cables
If you plan to set up two computers in the same room, you can use a single
phone jack. Keep in mind that at all times at least one of the cards on your
phoneline network must be plugged into a phone jack. Also keep in mind that
the phone jack must be for an active phone line. The phoneline network cards
depend on the small voltage that it is on your phone lines to function properly.
Installing USB Adapters
USB is the simplest way to install a network adapter. It is a simple matter of
using the included USB cable to connect the DHN-120 to an open USB port
on any PC or laptop you wish to connect. Please make sure that each
computer is off before plugging the unit in. Once you have created your
network, you will be able to hot-plug the DHN-120 at will, but for the
purposes of this manual it is best if you initially install the adapters with your
computers powered off.
Installing Cables
The cable included in the box is 15 feet in length. If you need a longer cable,
they are sold at most electronics stores. If you want to use a phone on the
same phone jack, we recommend that you purchase a splitter for the jack.
If you plan to use 2 or more phone jacks, make sure that they are (1) active
and (2) on the same line (the same phone number). The Home Phoneline
adapters will NOT interfere with your normal phone, analog modem, or DSL
modem but they do require an active phone line to work.
With the power off on your computers, run the first cable from your DHN-
120 USB HPNA 2.0 Network Adapter directly to the phone jack. If you have
two available phone jacks on the same line (telephone number) then simply
repeat this step for any other machines you would like to add to your home
phoneline network like the picture below, Figure 1:

Figure 1: Connecting Cables
If you plan to have two computers in the same room and only have one phone
jack, you can "daisy chain" the computers together. Simply run your first
phoneline cable from one of ports on the first DHN-120 to an available, active
phone line. Then run the second cable from the second port of the first DHN-
120 to one of the ports on the second DHN-120.
If you have a free port available on the DHN-120, it can be used to plug in a
phone or modem. The DHN-120 won't interfere with your phone, DSL, or
modem signal.
Congratulations: The hardware is ready to be configured into a network.

Chapter 3 Installing Software
You have completed the hardware installation necessary to start operating
your network. But, before you start sending those print jobs to the printer in
the other room or start playing fast paced network games with your family,
you need to tell your computers that they are connected to a network – that is,
you need to install the Networking System Software. This will consist
primarily of installing device drivers for your Network Adapters. Device
drivers help the operating system on your computer to identify and operate
devices such as printers and Network Adapters.
Installing Software under Windows 98
Since the DHN-120 is Plug-and-Play, Windows 98 recognizes that you have
added a Network Adapter and requests that you provide the necessary device
driver. The Windows 98 installation CD will be needed to complete this
installation.
A. Power ON your computer.

B. Windows 98 will detect the new hardware, and will launch the
Add New Hardware Wizard. The wizard will find your new "D-
Link DHN-120", as shown in Figure 2.
Figure 2: Add New Hardware Wizard
C. Insert the DHN-120 Drivers CD provided with your kit into your
CD-ROM drive and click "Next >" to continue.

Chapter 4 Networking Basics
You may have had some ideas about how to use your new network prior to
installing the DHN-120 – sharing files, printing from any computer on the
network, or accessing the Internet on multiple computers with one
connection. This section will help you get started on those ideas or even give
you some new ones. However, this section is not intended to be a
comprehensive guide to networking, it is just an outline of a few networking
basics.
If you are interested in learning more about networking, we have identified
some Internet resources that may be of interest:
D-Link Systems, Inc.
www.dlink.com
D-Link is one of the largest manufacturers of Ethernet products in the world.
D-Link’s technological expertise and dedication to providing quality products
at a low price makes D-Link a good place to watch for the newest in
networking innovations. Or, you may want to get the newest drivers available
for your Network Adapters.
TCP/IP Protocol
Before you start sharing files and printers, you need to set the IP address for
each of your computers. An IP address is just that, an address. It tells other
computers on the network where your computer is so that they can
communicate. For your first computer you will add a fixed IP address. For
each computer you add to the network, you will need to follow these same
steps, but add a different address.
O. From the Start menu, go to Settings-Control Panel, as shown in
Figure 12.

14
Figure 12: Start > Settings > Control Panel
P. Double Click the Network icon in the Control Panel, as shown in
Figure 13.
Figure 13: Control Panel

15
This Window will appear, as shown in Figure 14.
Figure 14: Network
Q. Highlight the line that says "TCP/IP >D-Link DHN-120 10Mb
Home Phoneline USB Adapter" and press the "Properties" button.

16
R. This will open the TCP/IP properties window. Make sure the "IP
Address" tab is selected and then press the circle next to "Specify
an IP Address". Enter 192.168.0.1 for the IP address, and
255.255.255.0 for the Subnet Mask. After you have done this your
screen should look like this, as shown in Figure 15:
Figure 15: TCP/IP Properties
S. Now press OK, and press OK again. Your system will probably
prompt you to reboot at this point, just answer "Yes". That's it!

17
For each computer on your network you will need to follow these same steps,
with the exception that you will give each computer its own unique IP
address. So for your second computer enter 192.168.0.2 for the IP address
and 255.255.255.0 for the Subnet Mask. For your third computer set the
address as 192.168.0.3 and so on (192.168.0.4 for the 4th, 192.168.0.5, for the
5th....etc.). It does not matter which computer is which number, just that each
computer has its own unique number starting with 192.168.0.??? and the
same subnet mask of 255.255.255.0, as shown in Figure 16.
Figure 16: Specify an IP Address
Computer Identification
You may need to verify that each computer has a unique name and common
workgroup name.

18
T. On your Desktop, right-click the icon "Network Neighborhood"
and select "Properties" from the context menu, as shown in Figure
17.
Figure 17: Network Neighborhood
U. Click the "Identification" tab on the top of the dialog box.
V. Type a unique, identifying name for this particular computer in the
"Computer name:" box. This will be the name that other
computers on your network will use to communicate with this
computer. Each computer’s name must be unique on a particular
network or confusion will result. (The computer’s name should be
15 or fewer characters with no spaces.)
W. Type the workgroup name this computer will be a part of in the
"Workgroup:" box. All of the computers on your network should
have an identical Workgroup name.
X. The "Computer Description:" box is optional. You may enter a
description that will help you identify this computer on your
network. Then click "OK".
