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.
Note: For help with DHCP configuration, see the link to the online document “ITCP/IP
Networking Basics” in Appendix B.

Connecting the Gateway
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.
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.
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.
c. Connect the gateway to your computer with either an Ethernet or USB cable.
Note: The USB connection option is only available for Windows PCs. Also,

Note: The CGD24G 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.
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.

NETGEAR strongly recommends that you use wireless security. This chapter includes:

• “Manually Configuring Your Wireless Settings and Security” on page 2-3
• “Using Push 'N' Connect (WPS) to Configure Your Wireless Network and Security” on
page 2-10

Planning Your Wireless Network
For compliance and compatibility between similar products in your area, the operating channel
and region must be set correctly.
To configure the wireless network, you can either specify the wireless settings, or you can use WiFi Protected Setup (WPS) to automatically set the SSID and implement WPA/WPA2 security.
• To manually configure the wireless settings, you must know the following:
– SSID. The default SSID for the gateway is Wireless.
– The wireless mode (802.11g, or 802.11b) that each wireless adapter supports.
– Wireless security option. T o successfully implement wireless security , check each wireless
adapter to determine which wireless security option it supports.
See “Manually Configuring Your Wireless Settings and Security” on page 2-3.

Wireless Cable Modem Gateway CGD24G User Manual
• Push 'N' Connect (WPS) automatically implements wireless security on the gateway while, at
the same time, allowing you to automatically implement wireless security on any WPSenabled devices (such as wireless computers and wireless adapter cards). You activate WPS by
pressing a WPS button on the gateway, clicking an onscreen WPS button, or entering a PIN
number. This generates a new SSID and implements WPA/WPA2 security.
Note: NETGEAR’s Push 'N' Connect feature is based on the Wi-Fi Protected Setup
(WPS) standard (for more information, see http://www.wi-fi.org). All other W i-
Fi-certified and WPS-capable products should be compatible with NETGEAR
products that implement Push 'N' Connect.
To set up your wireless network using the WPS feature:
– Use the WPS button on the side of the gateway (there is also an onscreen WPS button), or
enter the PIN of the wireless device.
– Make sure that all wireless computers and wireless adapters on the network are
Wi-Fi
certified and WPA or WPA 2 capable, and that they support WPS configuration.
See “Using Push 'N' Connect (WPS) to Configure Your Wireless Network and Security” on
page 2-10.
Wireless Placement and Range Guidelines
The range of your wireless connection can vary significantly based on the physical placement of
the gateway. The latency, data throughput performance, and notebook power consumption of
wireless adapters also vary depending on your configuration choices.
For best results, place your gateway according to the following guidelines:
• Near the center of the area in which your PCs will operate.
• In an elevated location such as a high shelf where the wirelessly connected PCs have line-ofsight access (even if through walls).
• Away from sources of interference, such as PCs, microwave ovens, and 2.4 GHz cordless
phones.
• Away from large metal surfaces.
• Put the antenna in a vertical position to provide the best side-to-side coverage. Put the antenna
in a horizontal position to provide the best up-and-down coverage.

• If using multiple access points, it is better if adjacent access points use different radio
frequency channels to reduce interference. The recommended channel spacing between
adjacent access points is 5 channels (for example, use Channels 1 and 6, or 6 and 11).
The time it takes to establish a wireless connection can vary depending on both your security
settings and placement. WEP connections can take slightly longer to establish. Also, WEP
encryption can consume more battery power on a notebook computer.
Wireless Security Options
Indoors, computers can connect over 802.1 1g wireless networks at a maximum range of up to 30 0
feet. Such distances can allow for others outside your immediate area to access your network.
Unlike wired network data, your wireless data transmissions can extend beyond your walls and
can be received by anyone with a compatible adapter. For this reason, use the security features of
your wireless equipment. The CGD24G gateway provides highly effective security features which
are covered in detail in this chapter. Deploy the security features appropriate to your needs.
There are several ways you can enhance the security of your wireless network:
• WEP. Wired Equivalent Privacy (WEP) data encryption provides data security. WEP Shared
Key authentication and WEP data encryption block all but the most determined eavesdropper.
This data encryption mode has been superseded by WPA-PSK and WPA2-PSK.
• WPA-PSK (TKIP), WPA2-PSK (AES). Wi-Fi Protected Access (WPA) using a pre-shared
key to perform authentication and generate the initial data encryption keys. The very strong
authentication along with dynamic per frame re-keying of WPA makes it virtually impossible
to compromise.
• Restrict access to your router.
For more information about wireless technology, see the link to the online document in “Wireless
Networking Basics” in Appendix B.
Manually Configuring Your Wireless Settings and Security
You can view or manually configure the wireless settings for the gateway in the Wireless Settings
screen. If you want to make changes, make sure to note the current settings first.
Note: If you use a wireless computer to change the wireless network name (SSID) or
wireless security settings, you will be disconnected when you click Apply. To
avoid this problem, use a computer with a wired connection to access the gateway.
