Relationship among the Devices
What the Modem Does
The Wireless Gateway provides high-speed Internet access as well as cost-effective fax/modem services
over residential, commercial, and education subscribers on public and private networks via an existing
CATV infrastructure. The IP traffic can transfer between the Wireless Gateway and EURO-DOCSIS
compliant head-end equipment. The data security secures upstream and downstream communications.
What the Modem Needs to Do Its Job
The Right Cable Company: Make sure your local cable company provides data services that
use cable TV industry-standard EURO-DOCSIS compliant technology.
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 Cable Modem (CM) Media Access Control (MAC) address
SSID, WEP/WPA-PSK information

Chapter 1: Connections and Setup

Please verify the following with the cable company
The cable service to your home supports EURO-DOCSIS compliant two-way modem access.
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 whenever you need.
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.
Please verify the following on the Wireless Gateway
The on/off button on the rear panel must be in the ON mode = on “1”

Connecting the Wireless Gateway to a Single Computer
This section of the manual explains how to connect your Wireless Gateway to the Ethernet port on your
computer and install the necessary software. Please refer to Figure 1 to help you connect your Digital
Cable Modem for the best possible connection.
Attaching the Cable TV Wire to the Wireless Gateway
1. Locate the Cable TV wire. You may find it one of three ways:
a. Connected directly to a TV, a Cable TV converter box, or VCR. The line will be connected to
the jack which should be labeled either IN, CABLE IN, CATV, CATV IN, etc.
b. Connected to a wall-mounted cable outlet.
c. Coming out from under a baseboard heater or other location. See Figure 1 for the wiring
example.
Notes: For optimum performance, be sure to
connect your Wireless Gateway to the first point
the cable enters your home. The splitter must be
rated for at least 1GHz.

Chapter 1: Connections and Setup

11
Important Connection Information
The Wireless Gateway supports 4 Ethernet connections simultaneously.
Below are important points to remember before you connect the Wireless Gateway.
Ethernet Connection to a Computer
Make the connection to the modem in the following sequence:
1. Connect one end of the coaxial cable to the cable connection on the wall, and the other end to the
CABLE jack on the Wireless Gateway.
2. Connect the plug from the DC power supply into the POWER DCADAPTER jack on the Cable
Wireless Gateway, and plug the power supply into a DC outlet.
Note: Use only the power supply that accompanied this unit. Using other adapters may damage the unit.
3. Connect one end of the Ethernet cable (straight-wired, see below) to the Ethernet port on the back of
your computer, and the other end to the ETHERNET port on the Wireless Gateway.
Make sure that the Ethernet cable is straight-wired (not “null” or crossover-wired). However, you
will need a crossover-type cable if you are connecting the modem to a hub, or a hub within a port
switch that provides the same function.

Connecting More Than One Computer to the Wireless Gateway
If you need to connect more than one computer to TCW770, simply connect the computers to the
Ethernet ports on the rear panel.
Fig.3: Multiple-PC Connection
Note: You may need to check with your service provider in order to connect multiple computers.

Chapter 1: Connections and Setup

Turning on the Wireless Gateway
After installing the Wireless Gateway and turn it on for the first time (and each time the modem is
reconnected to the power), it goes through several steps before it can be used. Each of these steps is
represented by a different pattern of flashing lights on the front of the modem.
Note: All indicators flash once before the initialization sequence.
If all of the lights are flashing sequentially, it means the Wireless Gateway is automatically updating its
system software. Please wait for the lights to stop flashing. You cannot use your modem during this time.
Do not remove the power supply or reset the Wireless Gateway during this process.

Chapter 2: WEB Configuration
To make sure that you can access the Internet successfully, please check the following first.
1. Make sure the Ethernet connection between the Wireless Gateway and your computer is OK.
2. Make sure the TCP/IP protocol is set properly.
3. Subscribe to a Cable Company.
Accessing the Web Configuration
The Wireless Gateway offers local management capability through a built in HTTP server and a number
of diagnostic and configuration web pages. You can configure the settings on the web page and apply
them to the device.
Once your host PC is properly configured; please proceed as follows:
1. Start your web browser and type the private IP address of the Wireless Gateway on the URL
field: 192.168.0.1.
2. After connecting to the device, you will be prompted to enter username and password. By
default, the username is ―‖ and the password is ―admin‖.
3. We strongly recommend to change the default password ―admin‖on the first connection :
Please define a username and password for administration .
