Connecting to the Internet and VoIP
To configure the gateway to connect to the Internet.
1. From the main menu, select Basic Settings. The Basic Settings screen appears:
:
Dynamic IP
Static IP
Figure 1-5
•The WAN Default Gateway is the ISP router to which your gateway will connect.
• A DNS server is a host on the Internet that translates Internet names (such as
http://www.netgear.com) to numeric IP addresses. Typically your ISP transfers the IP
address of one or two DNS servers to your gateway during login. If the ISP does no t
transfer an address, you must obtain it from the ISP and enter it manually here. If you enter
an address here, you should reboot your PCs after configuring the gateway.

Chapter 2
Wireless Configuration
This chapter describes how to set up the wireless features of your wireless voice gateway. In
planning your wireless network, consider the level of security required. Select the location of your
wireless equipment in order to maximize the network speed.
Set up wireless features for the wireless voice gateway in this order:
1. Install the wireless voice gateway as described in Chapter 1, “Installing the Gateway”. The
wireless voice gateway should be working on your LAN before you set up the wireless
features.
2. Plan the location for the wireless voice gateway based on considerations in “Wireless
Placement and Range Guidelines”.
3. Use the form in section “SSID and Wireless Security Settings Form” on page 2-3 to keep track
of your settings.
4. Enter the wireless settings, and verify wireless connectivity as described in “Vie wing or
Changing Wireless Settings” and “WEP (Wired Equivalent Privacy)”.
For more information about wireless technology, see the link to “Wireless Communications” in
Appendix B, “Related Documents”.

Wireless Cable Voice Gateway Model CVG834G Reference Manual
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-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.
