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.

Figure 1-6

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.

Chapter 2

Wireless Configuration

For a wireless connection, the SSID, also called the wireless network name, and the wireless security setting must be the same for the gateway and wireless computers or wireless adapters. NETGEAR strongly recommends that you use wireless security. This chapter includes:

“Planning Your Wireless Network” on this page

“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

“Connecting Additional Wireless Client Devices” on page 2-13

“Wireless Guest Networks” on page 2-14

“Configuring Wi-Fi Multimedia” on page 2-18

“Turning on Access Control to Restrict Access by MAC Address” on page 2-19

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. To 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.

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 Wi- 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-of- sight 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 802.11g wireless networks at a maximum range of up to 300 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.
