Wireless Configuration
For a wireless connection, the SSID, also called the wireless network name, and the wireless
security setting must be the same for
NETGEAR strongly recommends that you use wireless security. This chapter includes:
• “Planning Your Wireless Network”
• “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 2-9
• “Connecting Additional Wireless Client Devices” on page 2-13
Planning Your Wireless Network
For compliance and compatibility between similar products in your area, the operating channel
and region must be set correctly.
the gateway and wireless computers or wireless adapters.
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 WiFi-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 2-9.
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.
2-2 Wireless Configuration
v1.0, September 2009
Wireless Cable Gateway CG3000D/CG3100D User Manual
Wireless Security Options
Indoors, computers can connect over 802.11n 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 Voice 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.
To view or manually configure the wireless settings:
1. Log in to the gateway as described in “Logging In to Your Gateway” on page 1-4.
