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: _____________________________________________
Port: _____________________________________________
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.

Access List
Turn Access Control On
Access control is disabled by default so that any computer
configured with the correct SSID can connect. See
“Configuring Your Wireless Card Access List”
.
Security Option
WEP (Wired Equivalent Privacy) 128-bit
encryption is the default setting
WEP security uses encryption keys and data encryption for
data security. See

Other Security Options
•
Disable
. Wireless security is disabled. This setting can be
used to establish wireless connectivity before
implementing wireless security. NETGEAR strongly
recommends that you use wireless security.
•

. WEP security
uses encryption keys and data encryption for data
security. You can select 64-bit. See
“WEP (Wired
Equivalent Privacy)”
.
•
WPA options:
The wireless voice gateway supports
WPA-PSK, WPA, WPA2-PSK, and WPA2 security. See
“WPA-PSK (WiFi Protected Access Pre-Shared Key)”
, or
“WPA2-PSK (WiFi Protected Access 2 Pre-Shared
Keys)”
.
