Wall Mounting
Number of screws: 2 pieces.
Direction for wall mounting: LED panel upward.
Dimension for the screw: 4.4 mm.
There are 4 slots on the underside of the gateway that can be used for wall mounting.
Note: When wall mounting the unit, ensure that it is within reach of the power outlet.
You will need 2 suitable screws which screw diameter would be 4.4 mm to wall mount the Cable
Modem..
To do this:
1. Ensure that the wall you use is smooth, flat, dry and sturdy and use the 4 screw holes which are
101.6 mm apart from each other.
2. Fix the screws into wall, leaving their heads 3 mm (0.12 inch) clear of the wall surface.
3. Remove any connections to the unit and locate it over the screw heads. When in line, gently
push the unit on to the wall and move it downwards to secure.

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 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.

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
Important Connection Information
The Wireless Gateway supports 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 A Computer to the Wireless Gateway
If you need to connect more than a computer to TCW750-4, 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
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.

This page is used to change the password that enables you to access the gateway web pages next time.
The default User ID is “ ”(EMPTY), and the password is “admin”. The password can be a maximum of 8
characters and is case sensitive. In addition, this page can be used to restore the gateway to its original
factory settings. Use this with caution, as all the settings you have made will be lost. To perform this reset,
set Restore Factory Defaults to Yes and click Apply. This has the same effect as a factory reset using the
rear panel reset switch, where you hold on the switch for 15 seconds, then release it.

4. Diagnostics
This page offers basic diagnostic tools for you to utilize when connectivity problems occur. When you
ping an Internet device, you send a packet to its TCP/IP stack, and it sends one back to yours. To use the
ping Test, enter the information needed and press Start Test; the Result will be displayed in the lower part
of the window. Press Abort Test to stop, and Clear Results to clear the result contents.
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 have no firewall, such as the PCs on your LAN side.
