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.

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.
