Wireless Placement and Range Guidelines

The range of your wireless connection can vary significantly based on the physical placement of

the wireless voice 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 wireless voice gateway:

•

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.

SSID and Wireless Security Settings Form

For a new wireless network, print or copy this form and fill in the settings. For an existing wireless

network, the person who set up or is responsible for the network can get the settings. Be sure to set

the Regulatory Domain correctly as the first step.

•

SSID

.

The Service Set Identification (SSID) identifies the wireless local area network.

NETGEAR is the default SSID. However, you may customize it by using up to 32

alphanumeric characters. Write your customized SSID on the line below.

____________________________________________________

The SSID in the wireless voice gateway is the SSID you configure in the wireless adapter card.

All wireless nodes in the same network must be configured with the same SSID.

•

Authentication.

Circle one: Open System or Shared Key. Choose Shared Key for more security.

To use Shared Key, all devices in the network must be set to Shared Key and have the same

keys in the same positions as those in the CBVG834G.

•

WEP Encryption Keys.

For all four keys, choose the Key Size. Circle one: 64, or 128 bits.

Key 1: ______________________________________________

Key 2: ______________________________________________

Key 3: ______________________________________________

Key 4: ______________________________________________

•

WPA-PSK (Pre-Shared Key)

and

WPA2-PSK

. Record the WPA-PSK or WPA2-PSK key.

Key: _____________________________________________

(8-63 characters)

•

WPA

and

WPA2 RADIUS

Settings. For WPA and WPA2, record the following settings for

the primary and secondary RADIUS servers.

Server Name/IP Address: _____________________________________________

Shared Key: _____________________________________________

Use the procedures described in the following sections to configure the CBVG834G. Store this

information in a safe place.

Viewing or Changing Wireless Settings

To view or change the wireless settings:

1.

Connect a computer to the wireless voice gateway using an Ethernet or USB cable as

described in

“Installing the Voice Gateway” on page 1-4

.

2.

Enter

in the address field of your Internet browser. Log in to the gateway

with either of the default user names,

MSO

or

admin

.

3.

From the main menu, select Wireless Settings. The Wireless Setting screen displays:

Note:

If you use a wireless computer to change wireless settings such as the SSID, you

will be disconnected when you click

Apply

. Reconfigure your wireless computer

to match the new settings, or access the wireless voice gateway from a wired

computer to make further changes.

For initial configuration and test, leave the settings unchanged.

5.

If you make changes, you must click

Apply

to save the changes.

6.

Configure and test your computers for wireless connectivity.

Program the wireless adapter of your computers to have the same SSID and wireless security

settings as your wireless voice gateway. Check that they have a wireless link and are able to

obtain an IP address by DHCP from the wireless voice gateway. If there is interference, adjust

the channel.

The following table explains the Wireless Setting screen.

Description

Wireless

Network

Name (SSID)

The SSID is also known as the wireless network name. The

default SSID is printed on the bottom label of each unit. Any

wireless device that will connect to this wireless voice

gateway must use the same SSID.

If you want to change the SSID, you can enter a

32-character (maximum) name in this field. The characters

are case-sensitive.

Channel

The wireless channel used by the gateway. The default is

Channel 6.

Do not change the wireless channel unless you experience

interference (shown by lost connections or slow data

transfers). If this happens, you might need to experiment

with different channels to see which is the best.

Wireless Access

Point

Enable Wireless Access

Point

On by default, this setting enables the wireless radio, which

allows the wireless voice gateway to work as a wireless

access point.

Turning off the wireless radio can be helpful for

configuration, network tuning, or troubleshooting.

Allow Broadcast Name

(SSID)

On by default, the wireless voice gateway broadcasts its

SSID, allowing wireless stations that have a null (blank)

SSID to adopt the correct SSID. If you disable broadcast of

the SSID, only devices with the correct SSID can connect.

This nullifies the wireless network discovery feature of some

products such as Windows XP, but the data is still fully

exposed to a determined snoop using specialized test

equipment like wireless sniffers. For this reason NETGEAR

recommends that you also enable wireless security.

Other Security Options

•

Disable

. Wireless security is disabled. This setting can be

used to establish wireless connectivity before
