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.
• 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).

Chapter 1: Overview 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 802.11g Wireless. These 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.
This installation guide takes you through all the necessary steps for easy installation. Please refer
to the troubleshooting section for any improper behavior.
Even if you consider to use the gateway in a wireless mode only, it is highly recommended to
perform all the settings through a wired connection: USB or Ethernet first.
• If you intend to connect the Gateway though USB, please go to Chapter 2, USB Connection,
page XX.
• If you intend to connect the Gateway though Enternet, please go to Chapter 2, Ethernet
Connection, page XX.
• If you already have a network card, follow the next section.
Your PC: Installing a PC Network Card
If your PC does not already support Ethernet or USB, you must install a network interface card.
Following is an example setup procedure:
1. Install an Ethernet card on your motherboard, following the card’s directions.
2. Power up your PC and follow the Add New Hardware Wizard’s instructions to install the
driver. When asked to restart your computer at the end of the installation, click Yes.
3. After restarting the system, right-click My Computer on the desktop, select Properties, click
the Device Manager tab, and then double-click Network adapters to confirm that the
Ethernet driver is properly installed.

hole” on the back panel. It performs two functions:
• Basic Reset – Press and release the switch to make
it perform the same function as disconnecting the
power from the modem. It will start up again in
Initialization Mode, see page 24.
• Factory Default Reset – Unplug the modem from the AC power. Press and hold the reset
switch while plugging the modem into AC power. Continue holding the switch. Release the
switch when all lights come on (about 6 seconds). This will return the modem to a factory
“out of box” condition. This should only be done if the cable modem has been taken out of
service in one location and is being reconnected to a different service, or if instructed to
do so by your cable company.

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).
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
Fig. 10

Name field empty, and enter admin in lowercase letters in
the Password field (admin is the default password). Then,
click the OK button.
3. If you are in CM or CH mode, the Basic webpage group
hyperlink is visible. In this case, select the Basic Setup web
page by using the hyperlinks in the sidebar at the left of the
screen. Otherwise, skip to step 4. Based on the setup
instructions from your cable company, you may need to
enter the following information.
LAN IP Address: The value for the gateway’s local IP address
is shown on the Setup screen. The default value is
192.168.0.1. We recommend you keep this setting.
Host Name and Domain Name: These fields allow you to
provide a host name and domain name for the gateway.
These fields are usually left blank. If requested by your cable
company, complete these two fields.

Static IP Address and IP Mask: If your cable company says that you are connected through a
static or fixed IP address, you should enter the field 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 conflict, causing
your connection to the network to be rejected.
4. The gateway provides a Status Security webpage where you
can change the web page’s access password and restore
factory default of the gateway. Also, you can enable/disable
the DHCP Server function and change the default “admin”
password to the desired password.
IMPORTANT: If you have previously enabled any InternetSharing Proxy server software on any of your PCs, disable it.
Fig. 12
Some examples of Internet-sharing software are Internet LanBridge, Wingate, ICS, and Sygate. To
disable your Internet-sharing software:
• If you are running Netscape Navigator: Click Edit >> Preference >> Advanced >> Proxies >,
and click Direct Connection to the Internet.
• If you are running Internet Explorer v5 or better, click Start >> Settings >> Control Panel >>
Internet Options >> Connections >> LAN Settings. Remove the checks from all three boxes.
Click OK to continue.
5. Click the Apply button to save your settings. Close the web browser.
6. Restart your computers so that they can obtain the gateway’s new settings.
Your PC should now be able to access the Internet. The next steps are now:
1. Configure your Gateway such that it is able to support additonal PCs through a wired or
wireless connection.
2. Define the Firewall settings (optional).

Three Networking Modes
Your gateway can be configured to provide connectivity between your cable company and your
home LAN in any one of three Networking Modes: CM, RG, and CH. This mode setting is under the
control of your cable company, who can select the mode to match the level of home networking
support for which you have subscribed. All units ship from the factory set for the RG mode, but a
configuration file which the cable company sends the cable modem section during its
initialization can change it. This instruction book describes the RG mode as available out of the
factory.
The Wireless Cable Gateway offers local management capability through a built in HTTP server
and a number of diagnostic and configuration web pages. These pages are available from http://
192.168.0.1 in Residential Gateway (RG) and Cable Home (CH) modes, and http://192.168.100.1 in
Cable Modem (CM) mode. Not all pages are available in some modes.
Some information on two of the following web pages MUST BE configured, as explained in
Mandatory User Configuration: Status…Security web page and Basic...Setup web page.
In addition, more configuration and diagnostics are possible through the following additional web
pages, most of which are aimed at controlling the advanced networking functions of the gateway.
To navigate between pages, use the hyperlinks on the sidebar which appear on the left side of all
pages.
Your cable company may not support the reporting of some items of information listed on your
gateway’s internal web pages. In such cases, the information field appears blank. This is normal.
In the CM Mode, the simplest configuration mode of the gateway, or in the CH Mode, where you
have subscribed to an outside service (your cable company or another party) to remotely manage
your home network configuration, you will see only the Status and Wireless web page hyperlinks
in the sidebar, indicating only these page groups are available.
In the RG Mode, the mode where you manage your home network configuration, you will see web
page hyperlinks to all five page groups: Status, Basic, Advanced, Firewall, and Wireless. The
following section explains all of the available pages for all of the modes.

Status Web Page Group
Software Web Page (Fig. 12)
The Information section of this page provides hardware and
software information about your gateway that may be useful to
your cable company. You can view your operating software
version but not change it. This is because your gateway adheres
to the DOCSIS Cable Modem standard, which requires that your
cable company perform any software upgrade of the gateway
Fig. 12
from the gateway WAN side.
The Status section of this page shows how long your gateway has
operated since last being powered up, and some key information
the Cable Modem section received during the initialization
process with your cable company. If Network Access shows
“Allowed,” then your cable company has configured your gateway
to have Internet connectivity. If Network Access shows otherwise,
you may not have Internet access, and should contact your cable
company to resolve this.
Connection Web Page (Fig. 13)
This page reports diagnostic information about the initialization

Diagnostics Web Page (Fig. 15)
This page verifies you have IP connectivity from your gateway
to other IP addresses on the WAN or LAN side, such as when
you want to confirm you have successfully configured one of
your PCs for TCP/IP operation.
When you ping an Internet device, you send a packet to its TCP/
IP stack, and it sends one back to yours. Enter the IP address
you want to ping, then click Start Test. Wait a few seconds,
then click your web browser’s refresh button. Success reported
in the Results box means IP connectivity is working from your
CM TCP/IP stack to the target’s stack.
Note: Firewalls may cause pings to fail but still provide you TCP/IP
access to selected devices behind them. Keep this in mind when pinging
a device that may be behind a firewall. Ping is most useful to verify
connectivity with PCs you know have no firewall, such as your own PCs
on your LAN side.

This page gives you the ability to enter some data your cable
company may require, as explained before in Mandatory User
Configuration. In addition, it enables you to change your
default LAN side IP address from 192.168.0.1, and to view your
WAN side IP address and lease information.
Your gateway can provide NAT/PAT (Network and Port Address
Fig. 16
Translation) as an element of security to prevent others from
reaching your PCs when not authorized. To accomplish this, the
gateway watches packets you send from your PC to Internet
sites. Each time you send to a site (destination IP address) and
application at that site (port), it translates your PC’s original IP
and source port to new ones, and adds a row to its Connection
Table maintained internally. (Note the different meaning of
‘connection’ here to describe an IP connection versus a physical
cabling connection). If and when that site/application replies, it
looks up the connection and reverses the IP/port process to
direct the response to your PC.
The Connection Table manages itself, but you can also force
this table to be cleared manually. To do this, click the Renew
NAT Lease button.
You can enter a spoofed MAC address that causes your gateway
networking stack to use that MAC address when
communicating instead of the usual WAN MAC address (CM
label + 2, as explained in Chapter 1). Enter the desired MAC
address and press Apply.
Caution: If you enter a MAC address in use by another party, it
can cause an address conflict on the network that could affect
both you and that party.

DHCP Web Page (Fig. 17)
This page gives you the ability to activate and deactivate the
DHCP server function of your gateway, and, if the DHCP server
is activated, to see DHCP leases it has provided.
With this function activated, your cable company’s DHCP server
provides one IP address for your gateway, and your gateway’s
Fig. 17
DHCP server provides IP addresses, starting at the address you
set in Starting Local Address, to your PCs. A DHCP server leases
an IP address with an expiration time.
To change the lowest IP address that your gateway will issue to
your PCs, enter it into the Starting Local Address box and then
click Apply.
To set the maximum number of PCs to which the gateway will
issue IP addresses, enter it in the Number of CPEs box and then
click Apply. (CPE is another term sometimes used for PC.) The
DHCP Client Lease Info section shows leases the gateway DHCP
server has made, including the IP and MAC addresses of each
PC’s TCP/IP stack. Since MAC addresses are unique and
permanently fixed into hardware, you can identify any PC listed
by its MAC address. The gateway provides leases for 1 hour, and
has an automatic renewal mechanism that will keep extending
a lease as long as the associated PC remains active. If your PC is
set to “obtain an IP address automatically,” it is set to perform
DHCP each time it is rebooted.
You can cancel an IP address lease by selecting it in the DHCP
Client Lease Info list and then clicking the Force Available
button. If you do this, you may have to perform a DHCP Renew
on that PC, so it can obtain a new lease.

Forwarding Web Page (Fig. 22)
For LAN <=> WAN communications, the gateway normally only
allows you to originate an IP connection with a PC on the
WAN; it will ignore attempts of the WAN PC to originate a
connection onto your PC. This protects you from malicious
attacks from outsiders. However, sometimes you may wish for
anyone outside to be able to originate a connection to a
Fig. 22
Fig. 23
particular PC on your LAN if the destination port (application)
matches one you specify.
This page allows you to specify up to 10 such rules. For
example, to specify that outsiders should have access to an FTP
server you have running at 192.168.0.5, create a rule with that
address and Start Port = 20 and End Port = 21 (FTP port ranges)
and Protocol = TCP (FTP runs over TCP vs the other transport
protocol, UDP), and click Apply. This will cause inbound packets
that match to be forwarded to that PC rather than blocked. As
these connections are not tracked, no entry is made for them in
the Connection Table. The same IP address can be entered
multiple times with different ports.
Port Triggers Web Page (Fig. 23)
Some Internet activities, such as interactive gaming, require
that a PC on the WAN side of your gateway be able to originate
connections during the game with your game playing PC on the
LAN side. You could use the Advanced...Forwarding page to
construct a forwarding rule during the game, and then remove
it afterwards (to restore full protection to your LAN PC) to
facilitate this. Port Triggering is an elegant mechanism that
does this work for you, each time you play the game.
Port Triggering works as follows. Imagine you want to play a
particular game with PCs somewhere on the Internet. You make
a one time effort to set up a Port Trigger for that game, by
entering into Trigger Range the range of destination ports your
game will be sending to, and entering into Target Range the
Chapter 3 27
16096620 DCW615/25. 03 Network 6/26/03, 10:45 AM27
Chapter 3: Networking and Advanced Settings
range of destination ports the other player (on the WAN side) will be sending to (ports your PC’s
game receives on). Application programs like games publish this information in user manuals.
Later, each time you play the game, the gateway automatically creates the forwarding rule
necessary (see Advanced...Forwarding discussion above). This rule is valid until 10 minutes after it
sees game activity stop. After 10 minutes, the rule becomes inactive until the next matched
outgoing traffic arrives.
For example, suppose you specify Trigger Range from 6660 to 6670 and Target Range from 113 to
113. An outbound packet arrives at the gateway with your game-playing PC source IP address
192.168.0.10, destination port 6666 over TCP/IP. This destination port is within the Trigger Range,
so the gateway automatically creates a forwarding rule to forward any inbound packets destined
for port 113 to your game-playing PC at 192.168.0.10.
You can specify up to 10 port ranges on which to trigger.
DMZ Host Web Page (Fig. 24)
Use this page to designate one PC on your LAN that should be
left accessible to all PCs from the WAN side, for all ports. For
example, if you put an HTTP server on this machine, anyone will
be able to access that HTTP server by using your gateway IP
address as the destination. A setting of “0” indicates NO DMZ
PC. “Host” is another Internet term for a PC connected to the

802.11 networks use two authentication methods: open-
system authentication and shared-key authentication. In
both schemes, each mobile client (called a station) must
authenticate to the access point.
• Open-system authentication might better be called “no
authentication”, because no actual authentication takes
place: the station says “please authenticate me”, and the
Access Point does so, with no credential exchange.
• Shared-key authentication is somewhat more robust (except
that it depends on WEP). The station requests

authentication, and the access point (AP) responds with a WEP-encrypted challenge. The
station can decrypt the challenge and respond only if it has the correct WEP password.
When both “Open system and Shared key” options are selected, the authentication will be
done according to the mobile client station) request : with or without encryption?? In both

Your Gateway identifies wireless PCs by their WiFi MAC Address. This address consists of a
string of 6 pairs of numbers 0 – 9 and letters A - F, such as 00 90 4B F0 FF 50. It is usually
printed on the WiFi card of the device (e.g. the PCMCIA card in a laptop). It can also be
determined from a Windows DOS prompt as explained below.
The Connected Clients list on the Access Control Web Page always shows PCs that currently
have wireless connections to your Gateway. Your Gateway default access control configuration (“Allow everyone access”) allows access within reception range by any computer that
has your same privacy (key) settings. You might want to restrict the list of PCs having access
to the network (e.g. excluding neighbors or PCs used locally only). The process is described
