Router Side Panel

The side panel of the CGD24G gateway contains a WPS button. You can use the Wi-Fi Protected

Setup (WPS) feature with clients on the network that are Wi-Fi certified and WPA capable. See

“Using Push 'N' Connect (WPS) to Configure Your Wireless Network and Security” on page 2-10

.

What You Need Before You Begin

You need these three things before you can connect your gateway to the Internet:

•

A computer properly connected to the gateway as explained below.

•

Active Data Over Cable Internet service provided by cable modem account.

•

The Internet Service Provider (ISP) configuration information for your cable modem account.

Hardware Requirements

The CGD24G gateway connects to your LAN using either its twisted-pair Ethernet, USB, or

802.11b or 802.11g wireless port.

To use the CGD24G gateway on your network, each computer must have either an installed

Ethernet Network Interface Card (NIC), USB host port, or 802.11b or 802.11g wireless adapter. If

the computer will connect to your network at 100 Mbps, you must use a Category 5 (CAT5) cable

such as the one provided with your gateway.

LAN Configuration Requirements

For the initial connection to the Internet and configuration of your gateway, connect a computer to

the gateway which is set to automatically get its TCP/IP configuration from the gateway via

DHCP.

Figure 1-4

Note:

For help with DHCP configuration, see the link to the online document

“ITCP/IP

Networking Basics” in Appendix B

Connecting the Gateway

Follow these steps to install your gateway:

1.

Connect the gateway.

a.

Turn off your computer.

b.

Using the coaxial cable provided by your cable company, connect the gateway cable port

(A) to your cable line splitter or outlet.

c.

Connect the gateway to your computer with either an Ethernet or USB cable.

For an Ethernet connection, use the Ethernet cable that shipped with your gateway to

connect a LAN port (B)

to the Ethernet adapter in your computer.

Note:

First, install and set up the gateway using an Ethernet or USB connection to your

computer. Then configure the wireless settings. See

Chapter 2, “Wireless

Configuration

for instructions for wireless settings.

Figure 1-5

Warning:

The cable distribution system must be grounded in accordance with

ANSI/NFPA 70 and the National Electrical Code (NEC), in particular

section 820.93, Grounding of the Outer Conductive Shield of a

Coaxial Cable.

Note:

The USB connection option is only available for Windows PCs. Also,

Windows 95 does not support USB without special operating system

upgrades and patches.

v1.1, May 2009

For a USB connection, connect the USB cable to the USB port on your gateway and to a

USB port on your computer.

d.

Connect the power adapter to the gateway, and plug it into an outlet.

e.

Wait about 30 seconds for the lights to stop blinking, and then verify the following:

The power light is lit.

The cable link light is solid green, indicating a link has been established to the cable

network.

f.

Turn on your computer. If software usually logs you in to your Internet connection, do not

run that software or cancel it if it starts automatically.

2.

For an Ethernet connection, go to

step 3

. For a USB connection, install the USB driver.

a.

Insert the

Resource CD

that came with your gateway into the CD drive of your computer.

The Found New Hardware Wizard detects the gateway and prompts for the driver.

Figure 1-6

Note:

The CGD24G gateway uses Auto Uplink

TM

technology. Each local

Ethernet port senses whether the cable plugged into the port is attached to

a PC, or is attached to a switch or hub, which requires an uplink

connection. The port configures itself to accommodate either type of

cable. This eliminates the need for crossover cables.
