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 configuration 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 airow 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
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.
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.

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.

Section 2 - Installation
Verify the TCP/IP 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.
To configure TCP/IP on your Windows®Vista™PC:
1. Right click on Start->Network and select Properties
2. On the the following pop up window, select Tasks->Manage network connections.
3. Right-click Local Area Connection and click Properties. Look for an entry named TCP/IP. If you see TCP/IP listed next to your
Ethernet hardware device, you can now go to the section “Connecting the Cable Modem.” However, if TCP/IP is not listed, you
must complete the following steps.
• Scroll to the Internet Protocol version 4 TCP/IP option.
• Click to place a check mark in the Internet Protocol check box
• Click OK.
• You can now connect the cable modem.
To configure TCP/IP on your Windows 2000/XP PC:
1. Right-click the My Network Places icon on the Windows desktop.
2. Right-click Local Area Connection and click Properties. Look for an entry named TCP/IP. If you see TCP/IP listed next
to your Ethernet hardware device, you can now go to the section “Connecting the Cable Modem.” However, if TCP/IP is
not listed, you must complete the following steps.
• Scroll to the Internet Protocol TCP/IP option.
• Click to place a check mark in the Internet Protocol check box
• Click OK.
• You can now connect the cable modem.

Section 2 - Installation
Connecting the Cable Modem
Install the cable modem according to the following procedure:
1. Power off the computer.
2. Unplug the computer from the electrical wall outlet.
3. Make these connections:
• Connect the coaxial cable to the cable modem’s CATV cable connector. If you plan to have the cable connected
to a television as well as the cable modem, you must use a cable line splitter (not included).
• Plug the cable modem’s power adapter into a wall outlet or surge protector and into the cable modem’s
power jack.
• Plug one end of the Ethernet cable into the cable modem’s Ethernet port and the other end of the cable into
the existing NIC.
4. Plug in the computer.
5. Power on the computer. When installation is complete, your setup should resemble the illustration above. The
modem is operating properly if the Power, Cable, Status and ETH light emitting diodes (LEDs) are solid green
(lit and not blinking).

Section 2 - Installation
Using the USB Port
This section describes how to install the cable modem using the USB port. First you connect the hardware (cable modem and power
adapter). You then install the software drivers and verify that the modem is operating properly. The USB port does not support the
Macintosh®operating system. Using the USB port to connect to the Internet enables you to install the cable modem more quickly
and easily than connecting to the Internet using the computer’s Ethernet port, because you do not have to remove the case from the
computer to install a network interface card (NIC). Using the USB port, however, enables you to connect only one computer to the
cable modem. See “Installing the Cable Modem Using the Ethernet Port” if you wish to install the cable modem using the Ethernet
port.
If you have or plan on purchasing a router, please refer to the “Using the Ethernet Port” section on page 11. You cannot use the USB
connection with a router.
Note: Do not plug the USB modem into an external USB hub. Plug directly to your computer.
