• A computer with an active Ethernet port with DHCP enabled.

• An active account with your Internet Service Provider (ISP) for data services.

• Depending on how your ISP set up the Internet account, you need one or more of these
configuration settings to connect the gateway to the Internet:

– Host and Domain Names

– ISP Domain Name Server (DNS) Addresses

– Fixed or Static IP Address

• Each computer that will connect to the gateway must have an Ethernet Network
Interface Card (NIC), USB host port, or 802.11b or 802.11g wireless adapter.

Connecting the Gateway

1. For optimal wireless performance, attach the two brackets to the gateway and place it in
a vertical orientation as shown:

2. Turn off your computer. Use the coaxial cable provided by your cable company to
connect the gateway cable port (A) to your cable line splitter or outlet.

3. Connect the Ethernet cable (B) from your gateway’s LAN port to the Ethernet adapter in
your computer.

Connecting to the Internet

To configure the gateway and connect to the Internet:

1. 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.

2. For security reasons, the gateway has its own user name and password. When prompted,

enter admin for the user name and password for the password.

After you log in, the Basic Settings screen
displays.

3. Make sure that the Cable Network Settings field
is set correctly.

• DHCP (default setting). Your ISB will

automatically download the network
configuration settings. Go to Step 5.

• Stat ic IP. If your ISP assigned you a

permanent, fixed (static) IP address, select

Stat ic IP.

4. Enter the following settings provided by your

ISP:

• Static IP address

• Static IP mask (also known as the netmask) address

• Default gateway address

• Primary Domain Name Server (DNS) address

• Secondary DNS address

The Network Configuration settings automatically match the Cable Network Settings.

5. Click Apply to accept these settings.

6. Verify your Internet connection.

Note: Some cable Internet companies require you to notify them when you replace the

original cable modem so that they can register the MAC addresses.

If you had difficulty connecting to the gateway or to the Internet, see the DOCSIS 2.0
Advanced Cable Gateway CGD24N User Manual.

Configuring Wireless Connectivity

To connect to the gateway, your wireless devices must be configured to use the same wireless
network name (SSID) and wireless security settings as the gateway. This can be done with
Wi-Fi Protected Setup (WPS) or manually. NETGEAR strongly suggests that you implement
security to protect your network.

Note: There is a Wireless On/Off button located on the rear panel of the gateway. Before
attempting to connect wirelessly to the gateway, make sure that the Wireless LED is lit,
indicating that the wireless feature is turned on.

Using Push 'N' Connect (WPS) to
Configure Your Wireless Network

If the wireless clients in your network support Wi-Fi Protected Setup (WPS), you can use this
feature to automatically connect the wireless client securely and easily to the gateway. If you
do use WPS to configure your wireless network, the method of security will be Wi-Fi
Protected Access with Pre-Shared Key (WPA-PSK+WPA2-PSK) data encryption, and your
SSID will be a randomly selected name.

To initiate WPS using the push button on the gateway:

1. Press the WPS button on the rear panel of the gateway for over 5 seconds.

The green wireless status LED on the front of the Advanced Cable Gateway begins to
blink in a fast pattern. While the light is blinking in a fast pattern, you have 2 minutes to
enable WPS on the client that you are trying to connect to the gateway.

2. On the wireless client, follow its specific networking instructions to enable WPS, to
allow it to connect to the gateway.

The gateway’s green wireless status LED ceases blinking in a fast pattern and starts to
blink in a regular pattern when one of these conditions occurs:

• The gateway and the client establish a wireless connection.

• The 2-minute window period expires for establishing a WPS connection. If the

connection is not established, no WPS security settings will be specified in the
gateway.

Note: If your network contains wireless clients that are not WPS-capable, then set up your
wireless network and wireless security manually as described in the DOCSIS 2.0 Advanced
Cable Gateway CGD24N User Manual.
