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 ofce/home ofce (SOHO), or high-speed residential Internet access. The cable modem provides a downstream
speed of up to 38Mbps from the cable network to your computer and 30Mbps 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

Before You Begin
Local Cable Network Service
Before installing the modem:
• Remove any previous installations of wireless adapters
• Find the Serial Number, RF and Ethernet address located on a sticker on the cable modem and write them
here:
Serial Number S/N: ____________________
RF and ETH MAC: ____________________
• Contact your local cable service operator for Internet/cable network access. Your local cable operator will check
for cable access availability in your area, install a cable line (if necessary), provide you with an access account,
set up conguration and verify other technical details.
• Ask your local cable service provider about adding additional IP addresses to your account. See “ Which Installation
to Use?” for more information.
Prepare Your Workspace
To prepare your workspace:
• 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.
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. Remove the backing paper and
attach a foot to each of the corners on the cable modem; be sure to attach the feet on the surface that contains
the model information stickers, as shown.
• Do not restrict the airow around the cable modem.
• To enhance the best performance and proper function of the cable modem, place it on a horizontal surface or
workplace and make sure that the cable modem does not move when it is operating.

Section 2 - Installation
Installation
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.
To install the cable modem using the Ethernet port:
• Any PC running Windows®, Macintosh®, or Linux with an Ethernet adapter.
• TCP/IP protocol installed.
To install the cable modem using the USB port:
• Any PC running Microsoft Windows Vista™, XP, or 2000 operating systems.
• Original Windows Vista, XP, or 2000 installation CD or diskettes.
• An active USB port on your computer.

Section 2 - Installation
Using the Ethernet Port
This section 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 router 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.
When using the Ethernet connection, do NOT install the modem drivers. They are only for the USB connection.
