Rear Panel

The rear panel of the CG814WG v3 contains the connections identified below:

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 CG814WG v3 Gateway connects to your LAN using either its twisted-pair Ethernet, USB or

802.11b or 802.11g wireless port.

To use the CG814WG v3 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.

Internet Configuration Requirements

Depending on how your ISP set up your Internet account, you will need one or more of these

configuration settings to connect your gateway to the Internet:

• Host and Domain Names

• ISP Domain Name Server (DNS) Addresses

• Fixed or Static IP Address

Connecting the CG814WG v3 Gateway

Installation

Follow these steps to install your gateway:

1. Connect the gateway.

a. Turn off your computer.

Note: For help with DHCP configuration, see the link to the online document “Internet

Networking and TCP/IP Addressing” in Appendix B.

Note: Install and set up the CG814WG v3 Gateway using an Ethernet or USB

connection to your computer first. Then configure the wireless settings. See

Chapter 2, “Wireless Configuration” for instructions for wireless settings.

b. Using the coaxial cable provided by your cable company, connect the CG814WG v3 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.

Figure 1-3

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.

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

USB port on your computer.

d. Connect the power adapter to the CG814WG v3, and plug it into an outlet.

e. 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.

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

The power light is lit after turning on the gateway.

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

network.

The LAN lights are lit for any connected computers.

2. For an Ethernet connection, go to Step 3. For a USB connection, install the USB driver.

a. For a USB connection you must install the USB driver. Insert the NETGEAR 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.

Note: The CG814WG v3 Gateway uses Auto UplinkTM 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.

b. Browse to the Resource CD and install the USB driver by clicking through the Windows

wizard prompts.

3. Log in to the Gateway

a. Using the computer that you first used to access your cable modem Internet service,

connect to the gateway by typing http://192.168.0.1 in the address field of your Internet

browser. A login window opens.

b. Log in to the gateway.

• To log in as the parent, enter superuser for the user name and password for the

password, both in lower case letters.

• To log in as the child, enter admin for the user name and password for the password,

both in lower case letters.

Note: To connect to the gateway, your computer must be configured to obtain an IP

address automatically via DHCP. For instructions on how to do this, see the

link to “Preparing a Computer for Network Access” in Appendix B.

Figure 1-6

Note: For security reasons, the gateway has two sets of user names and passwords:

one for a parent and one for children. Only the parent’s login can be used to set

up Parental Control and MAC Filtering. The child’s login can configure all

other features of the gateway.

v1.0, June 2007

When you connect to the gateway the Gateway status screen opens.

4. Enter your Network Configuration.

• WAN IP Address: The IP Address that you would for your gateway in dotted decimal

notation.

• WAN Subnet Mask: The network number portion of an IP address. Unless you are

implementing subnetting, use 255.255.0.0 as the subnet mask.

•WAN Default Gateway: This is the ISP’s router to which your gateway will connect.

•WAN Primary and Secondary DNS: A DNS server is a host on the Internet that

translates Internet names (such as www.netgear.com) to numeric IP addresses. Typically

your ISP transfers the IP address of one or two DNS servers to your gateway during login.

If the ISP does not transfer an address, you must obtain it from the ISP and enter it

manually here. If you enter an address here, you should reboot your PCs after configuring

the gateway.

5. Click Apply to save your settings.

For more information about the Gateway Status screen see“Gateway Status” in Chapter 4.

Note: If you cannot connect to the gateway, see “Basic Functions” in Chapter 5.
