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
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-confi gure 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 fi nd on the
sticker on the gateway) :
• The serial number
• The model number
• The Media Access Control (MAC) address
Record your information here:
S.N.
XXXXXXXXXXXXXX
MODEL:
DCWXXX
MAC:
009064XXXXXX
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 fi rst.

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, or 802.11b Wireless, 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 confi gure your networked PCs to accept the IP addresses the
gateway assigns them (if applicable), and you will also need to confi gure the gateway with
settings provided by your cable company.

Activating the Wireless Cable Gateway
Initialization
1. Connect the power cable to the back of the gateway. For the fi rst few seconds of operation,
multiple LEDs will fl ash in unison while the gateway performs self-test diagnostics.
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)
• Confi guring - downloading and applying the cable company CM confi guration fi le
• Registering - establishing Internet access with the cable company
During this process, the LED indicators on the front of the unit indicate progress.
• DS – Flashing indicates Tuning; lit solid indicates Tuning step completed successfully.
• US – Flashing indicates Ranging; lit solid indicates Ranging step completed successfully.
• Online – Flashing indicates Connecting, Confi guring, Registering in progress; lit solid
indicates these steps completed successfully.
Chapter 1 15
Chapter 1: Connections and Setup
When the Online LED is lit solid, all gateway initialization and startup steps have been
completed successfully, and the gateway should be capable of providing connectivity
between your PCs on the gateway LAN-side and your cable operator on the gateway
WAN-side.
Mandatory User Confi guration
This feature allows you to confi gure 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 fi rewall software (such as ZoneAlarm and Watchdog) on all of your PCs.
To set up your gateway for internet access, you will use its built-in web pages feature. The
gateway includes a built-in HTTP server which can deliver many web-style pages of
information with which you can observe your current gateway settings and make changes.
1. Open your web browser. (It’s all right if you get an error
Fig. 8
message at this point. Continue following these directions).
Enter http://192.168.100.1 in the browser’s Address fi eld 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 fi eld empty, and enter admin in lowercase letters in
the Password fi eld (admin is the default password). Then,
click the OK button.
Fig. 9
16 Chapter 1
Chapter 1: Connections and Setup
3. This step is not required with most installations. However, based on setup instructions from
your cable company, you may need to enter the following information. To enter it, navigate
to the Network – WAN gateway web page by clicking Network at the top of the page, then
click WAN (on the left side of the page). Click the Apply button to save your settings.
Host Name and Domain Name: These fi elds allow you to provide a host name and domain
name for the gateway. These fi elds are usually left blank. If requested by your cable company,
complete these two fi elds.
Static IP Address and IP Mask: If your cable company says that you are connected through a
static or fi xed IP address, you should enter the fi eld of Default Gateway, Primary DNS and/or
Secondary DNS also.
Spoofed MAC Address: You can give a spoofed MAC Address to hide your gateway’s real MAC
address. However, this is NOT recommended, as this could cause an address confl ict, causing
your connection to the network to be rejected.
4. The gateway provides a Status Password webpage where you can change the web page’s
access password and restore factory default of the gateway. Also, you can change the default
“admin” password to the desired password. Click the Apply button to save your settings.
IMPORTANT: If you have previously enabled any Internet-Sharing Proxy server software on any of
your PCs, disable it.

Chapter 2: Networking
Communications
Data communication involves the fl ow of packets of data from one device to another. These
devices include personal computers, Ethernet and USB hubs, cable modems, digital routers and
switches, and highly integrated devices that combine functions, like the Wireless Cable Gateway.
The gateway integrates the functionality often found in two separate devices into one. It’s both
a cable modem and an intelligent wireless gateway networking device that can provide a host
of networking features, such as NAT and fi rewall. Figure 2 illustrates this concept, with the cable
modem (CM) functionality on the left, and networking functionality on the right. In this fi gure,
the numbered arrows represent communication based on source and destination, as follows:
Type of Communication
1. Communication between the Internet and your PCs
Example: The packets created by your request for a page stored at a web site, and the
contents of that page sent to your PC.
2. Communication between your cable company and the cable modem side
Example: When your cable modem starts up, it must initialize with the cable company,
which requires the cable company to communicate directly with the cable modem itself.
3. Communication between your PCs and the networking side

Chapter 2: Networking
Example: The Wireless Cable Gateway offers a number of built-in web pages which you can
use to confi gure its networking side; when you communicate with the networking side, your
communication is following this path.
Each packet on the Internet addressed to a PC in your home travels from the Internet downstream on the cable company’s system to the WAN side of your Wireless Cable Gateway. There it
enters the Cable Modem section, which inspects the packet, and, based on the results, proceeds
to either forward or block the packet from proceeding on to the Networking section. Similarly,
the Networking section then decides whether to forward or block the packet from proceeding on
to your PC. Communication from your home device to an Internet device works similarly, but in
reverse, with the packet traveling upstream on the cable system.
Cable Modem (CM) Section
The cable modem (or CM) section of your gateway uses DOCSIS Standard cable modem technology. DOCSIS specifi es that TCP/IP over Ethernet style data communication be used between the
WAN interface of your cable modem and your cable company.
A DOCSIS modem, when connected to a Cable System equipped to support such modems,
performs a fully automated initialization process that requires no user intervention. Part of this
initialization confi gures the cable modem with a CM IP (Cable Modem Internet Protocol) address,
as shown in Figure 3, so the cable company can communicate directly with the CM itself.
Networking Section
The Networking section of your gateway also uses TCP/IP (Transmission Control Protocol/ Internet
Protocol) for the PCs you connected on the LAN side. TCP/IP is a networking protocol that provides communication across interconnected networks, between computers with diverse hardware
architectures and various operating systems.
TCP/IP requires that each communicating device be confi gured with one or more TCP/IP stacks,
as illustrated by Figure 4. On a PC, you often use software that came with the PC or its network
interface (if you purchased a network interface card separately) to perform this confi guration. To
communicate with the Internet, the stack must also be assigned an IP (Internet Protocol) address.
192.168.100.1 is an example of an IP address. A TCP/IP stack can be confi gured to get this IP
