Prepare Your Workspace for the Cable Modem
Installation
Before installing the cable modem, you should prepare your workspace. You
can install the cable modem vertically with the included bracket, or install the
cable modem horizontally.
To prepare your workspace:
1 Position the cable modem so that it is located near the computer and the
wall cable outlet. There should be plenty of room to guide the cables away
from the cable modem without crimping them.
2 Prepare the cable modem:
For vertical installation: Place the cable modem securely in the
included stand.
For horizontal installation: Use the four included feet to install the
cable modem.

Introduction
Thank you for purchasing the D-Link “Broadband Cable Modem with USB &
Ethernet” DCM-201, which is an MCNS DOCSIS™ 1.1 cable modem
featuring the latest DOCSIS technology.
The cable modem enables your network cable operator to provide you with
broadband applications such as telecommunications, IP dedication for your
small office/home office (SOHO), or high-speed residential Internet access.
The cable modem provides a downstream speed of up to 38 Mbps from the
cable network to your computer and 10Mbps from your computer to the cable
network.
The DES data encryption helps ensure privacy for the transmitted
information. Another distinctive feature of the cable modem is its easy
installation, because DHCP and TFTP clients can obtain automatic access
to the IP address and configuration from their network servers via the
modem. SNMP agents permit remote configuration and monitoring from a
management station equipped with an SNMP server.

Features
Decide Which Installation Process to Use
The cable modem enables you to connect to the Internet using either your
computer’s Ethernet or USB port.
Be sure to follow the installation steps for the setup you want to use. Using
the Ethernet setup enables you to use a hub to connect multiple computers
to the cable modem. To do this, you might have to obtain additional IP
addresses from your cable operator.
Using the USB port enables you to install the cable modem more quickly and
easily than connecting to the Internet using the Ethernet port, because you do
not have to install a network interface card (NIC) into your computer. The
USB port, however, only enables you to connect one computer to the cable
modem.
See “Installing the Cable Modem Using the Ethernet Port”, or see “Installing
the Cable Modem Using the USB Port” in the following pages, for more
information.

Installing the Cable Modem Using the Ethernet
Port
CAUTION! Be sure to read this entire User’s Manual from front to back in
sequence before installing the D-Link DCM-201 USB/Ethernet Broadband
Cable Modem.
This chapter describes how to install the cable modem using the Ethernet
port. Using the Ethernet port enables you to use a single connection to the
Internet or use a hub to connect multiple computers to the cable modem. You
can also use multiple IP addresses from your cable operator when using the
Ethernet connection. See “Installing the Cable Modem Using the USB Port” in
this manual to set up the USB Connection.
You can use the Ethernet port to connect to the Internet with the following
operating systems: Windows 95, Windows 98, W indows 98SE, Windows
2000, Windows Me, Windows NT, Macintosh 7.6 (or later), and other popular
operating systems.
Verify the TCP/IP Protocol Configuration
Before installing the modem using the Ethernet setup, you must verify that
your computer has the TCP/IP protocol installed. Follow the procedure for
your operating system to verify or install the TCP/IP protocol.
Configuring TCP/IP on Windows 95, Windows 98, and
Windows Me
To configure TCP/IP on a computer with the Windows 95, Windows 98,
or Windows Me operating system:
1 Right-click the Network Neighborhood icon (Windows Me: the My Network
Places icon) on the Windows desktop and click Properties.
