Chapter 1: Connections and Setup

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 DOCSIS compliant headend 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 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

Illustrations contained in this document are for representation only.

Chapter 1: Connections and Setup

Please verify the following with the cable company

 The cable service to your home supports 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.

Chapter 1: Connections and Setup

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.

Fig. 1: Basic Home Wiring

Chapter 1: Connections and Setup

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 DC ADAPTER 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.

Chapter 1: Connections and Setup

Connecting More Than One Computer to the Wireless Gateway

If you need to connect more than one computer to DCW775, simply connect the computers to the Ethernet ports on the rear panel. You may also use a hub with an crossover Ethernet cable to connect more than 4 computer to the Wireless Gateway.

Fig.3: Multiple-PC Connection

Note: You may need to check with your service provider in order to connect multiple computers.

Illustrations contained in this document are for representation only.

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.

Illustrations contained in this document are for representation only.

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‖.

Status

1. Software

The information section shows the hardware and software information about your gateway. The status section of this page shows how long your gateway has operated since last time being powered

up, and some key information the Cable Modem 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 not, you may not have Internet access, and should contact your cable company to resolve this.
