What the Wireless Cable Gateway Does
The Digital Wireless Cable Gateway serves as a two-way high-speed bridge between your personal
computer and a cable Internet Service Provider (ISP). It converts information that originates from
the Internet or your computer into electronic messages that can be transported over the same
wires your cable company uses to transport video signals.
What the Wireless Cable Gateway Needs to Do Its Job
• The Right Cable Company: Make sure your cable company provides data services that use
cable TV industry-standard DOCSIS technology.
6 Chapter 1
16096620 DCW615. 01 Connect 3/21/03, 4:58 PM6
Chapter 1: Connections and Setup
• The Internet Service Provider (ISP): Your cable company provides you access to an Internet
Service Provider (ISP). The ISP is your gateway to the Internet. It provides you with a pipeline
to access Internet content on the World Wide Web (WWW).
Check with your cable company to make sure you have everything you need to begin; they’ll
know if you need to install special software or re-configure your computer to make your
cable Internet service work for you.
Contact Your Local Cable Company
You will need to contact your cable company to establish an Internet account before you can use
your gateway. You should have the following information ready (which you will find on the
sticker on the gateway) :
• The serial number
• The model number
• The Media Access Control (MAC) address
Record your information here:
Serial Number: _________________________
S.N.
XXXXXXXXXXXXXX
MODEL:
MAC:
DCWXXX
009064XXXXXX
Model Number: _________________________
MAC Address: __________________________
Please verify the following with the cable company:
• The cable service to your home supports DOCSIS-compliant two-way modem access.
•Your Internet account has been set up.
•You have a cable outlet near your PC and it is ready for cable modem service.
Note: It is important to supply power to the modem at all times. Keeping your modem plugged in will keep it
connected to the Internet. This means that it will always be ready when you are. To disconnect your computer
from the Internet, use the ON/OFF button to put the modem in standby mode.
Important Information
Your cable company should always be consulted before installing a new cable outlet. Do not
attempt any rewiring without contacting your cable company first.

Chapter 1: Connections and Setup
System Overview
The Wireless Cable Gateway is connected between your cable company and the PCs within your
home, as pictured previously in the Wireless Cable Gateway Overview. The connection to the cable
company is made by a coaxial cable, and is referred to as the WAN (Wide Area Network) side of
your Wireless Cable Gateway. The connections to your PCs are made by your choice of several
standard home networking methods: Ethernet, USB, 802.11b Wireless, or HPNA 2.0, and are
referred to as the LAN (Local Area Network) side of your Wireless Cable Gateway. Multiple PCs can
use any or all of the LAN side connections simultaneously to share your single cable company
connection, up to a maximum of 254 PCs total.
Unlike a simple hub or switch, the gateway’s setup consists of more than simply plugging
hardware together. You’ll need to configure your networked PCs to accept the IP addresses the
gateway assigns them (if applicable), and you will also need to configure the gateway with
settings provided by your cable company.

Chapter 1: Connections and Setup
Connecting Your Devices
1. Before you begin, make sure that all of your hardware is powered off, including the gateway,
PCs, hubs, and switches.
2. Connect one end of an Ethernet cable to one of the LAN ports (labeled 1, 2, 3, or 4) on the
back of the gateway and the other end to a standard port on a network device, e.g., a PC,
print server, hub, or switch. Repeat the above step to connect more PCs or network devices to
the gateway.
3. Connect the coaxial cable from the wall to the CABLE jack on the back of the gateway.
4. Connect the power supply cable to the Power jack on the back of the gateway, then plug the
supplied power cable into an AC power outlet.
Activating the Wireless Cable Gateway
Initialization
1. Turn on the gateway’s Power switch (the Power indicator on the front of the unit comes on.)
The Test indicator comes on for a few seconds when the gateway goes through its self-diagnostic
test. The indicator turns off when the self-test is complete.
The Cable Modem section of the gateway proceeds with DOCSIS initialization. In this process, the
CM performs the following sequence of steps. For a newly-installed gateway, this can take as
much as 20 minutes to complete.
•Tuning - searching for a downstream DOCSIS CM signal
• Ranging - establishing 2-way communication with the cable company
• Connecting - obtaining the CM IP Address (for IP Stack 1)
• Configuring - downloading and applying the cable company CM configuration file
• Registering - establishing Internet access with the cable company
During this process, the LED indicators on the front of the unit indicate progress.
• Receive - If it’s flashing, the CM is Tuning - searching for a downstream CM signal.
• Cable-Link - When Receive and Cable-Link are flashing, the modem is now tuned to a
downstream cable modem channel and can receive data. Now it searches for an upstream
channel so that it can send data.
Chapter 1 15
16096620 DCW615. 01 Connect 3/21/03, 4:58 PM15
Chapter 1: Connections and Setup
• USB - When Receive, Cable-Link, and USB are flashing, the modem is now communicating
start-up data both downstream and upstream.
• WLAN - When Receive, Cable-Link, USB, and WLAN are flashing, the modem has received
its IP address and is downloading its configuration file from the Internet Service Provider
(ISP).
•Test - When Receive, Cable-Link, USB, WLAN, and Test are flashing, the modem
configuration is complete. It is registering its “as-configured” setting with your Cable
Operator. Once complete, all LEDs stop flashing and the Power indicator stays on.
Mandatory User Configuration
This feature allows you to configure the gateway to function in your network and gain access to
the Internet through your cable company. Your ISP may require the use of a Host Name and
Domain Name. You will need to get the setup information from your ISP. If you do not have this
information, please contact your ISP before proceeding.
The instructions from your ISP will tell you how to set up your PC for Internet access.
Also, you must disable any Internet log-on software (such as Ivasion Winpoet or Enternet 300)
and any firewall software (such as ZoneAlarm and Watchdog) on all of your PCs.
1. Open your web browser. (It’s all right if you get an error
message at this point. Continue following these directions).
Fig. 14
Fig. 15
Enter http://192.168.100.1 in the browser’s Address field if
your gateway is in the CM Mode, or http://192.168.0.1 if it
is in the RG or CH Mode. Press the Enter key.
2. An Enter Network Password window appears (for Windows
XP users, the screen may look different). Leave the User
Name field empty, and enter admin in lowercase letters in
the Password field (admin is the default password). Then,
click the OK button.
