Introduction
This chapter describes the features of the NETGEAR Integrated ADSL Modem and Wireless
Router with Voice, Model DG834GV. The Integrated ADSL Modem Wireless Router with Voice
is a combination of a built-in ADSL modem, modem router, 4-port switch, and firewall which
enables your entire network to safely share an Internet connection that otherwise would be used by
a single computer.
Note: If you are unfamiliar with networking and routing, refer to “Internet Networking
and TCP/IP Addressing” in Appendix B to become more familiar with the terms
and procedures used in this manual.
About the Modem Router
The Integrated ADSL Modem and Wireless Router with Voice, Model DG834GV provides
continuous, high-speed 10/100 Ethernet access between your Ethernet devices. With minimum
setup, you can install and use the modem router within minutes.
The Integrated ADSL Modem Wireless Router with Voice provides multiple Web content filtering
options, reporting, and instant alerts. Parents and network administrators can establish restricted
access policies based on time of day, Web site addresses, and address keywords. They can also
share high-speed ADSL Internet access for up to 253 personal computers. The included firewall
and Network Address Translation (NAT) features protect you from hackers.
Introduction 2-1
v1.0, September 2006
Reference Manual for the Integrated ADSL Modem and Wireless Router with Voice, Model

and administrator logins. You can configure the modem rout er to ema il the log to you at
specified intervals. You can also configure the modem router to send immediate alert
messages to your email address or email pager whenever a significant event occurs.
2-2 Introduction
v1.0, September 2006
Reference Manual for the Integrated ADSL Modem and Wireless Router with Voice, Mode l
802.11 Standards-based Wireless Networking
The Integrated ADSL Modem Wireless Router with Voice includes an 802.11g-compliant
wireless access point, providing continuous, high-speed 10/100 Mbps access between your
wireless and Ethernet devices. The access point provides:
• 802.11g Standards-based wireless networking at up to 54 Mbps
• Works with both 802.11g and 802.11b wireless devices
• 64-bit and 128-bit WEP encryption security
• WEP keys can be entered manually or generated by passphrase
• Support for Wi-Fi Protected Access Pre-Shared Key (WPA-PSK) encryption and 802.1x
authentication
• Wireless access can be restricted by MAC address
Easy Installation and Management
You can install, configure, and operate the DG834GV within minutes after connecting it to the
network. The following features simplify installation and management tasks:
• Browser-based management
Browser-based configuration allows you to easily configure your modem router from almost
any type of personal computer, such as Windows, Macintosh, or Linux. A user-friendly Setup
Wizard is provided and online help documentation is built into the browser-based Web
Management Interface.
• Smart Wizard
The firmware in the modem router automatically senses the type of Internet connection, asking
you only for the information required for your type of ISP account.
• Remote management
The modem router allows you to log in to the Web management interface from a remote
location via the Internet. For security, you can limit remote management access to a specified
remote IP address or range of addresses, or you can choose a nonstandard port number.
• Diagnostic functions
The modem router incorporates built-in diagnostic functions such as Ping, DNS lookup, and
remote reboot. These functions allow you to test Internet connectivity and reboot the modem
router. You can use these diagnostic functions directly from the DG834GV when you are
connected on the LAN or when you are connected over the Internet via the remote
management function.
Introduction 2-3
v1.0, September 2006
Reference Manual for the Integrated ADSL Modem and Wireless Router with Voice, Model
• Visual monitoring
The modem router’s front panel LEDs provide an easy way to monitor its status and activity.
• Flash erasable programmable read-only memory (EPROM) for firmware upgrades.
Protocol Support
The DG834GV supports Transmission Control Protocol/Internet Protocol (TCP/IP) and Routing
Information Protocol (RIP). “Internet Networking and TCP/IP Addressing” in Appendix B
provides further information on TCP/IP.
• The Ability to Enable or Disable IP Address Sharing by NAT
The DG834GV allows several networked PCs to share an Internet account using only a single
IP address, which may be statically or dynamically assigned by your Internet service provider
(ISP). This technique, known as Network Address Translation (NAT), allows the use of an
inexpensive single-user ISP account. This feature can also be turned off comp let ely while
using the DG834GV if you want to manage the IP address scheme yourself.
• Automatic Configuration of Attached PCs by DHCP
The DG834GV dynamically assigns network configuration information, including IP, modem
router, and domain name server (DNS) addresses, to attached PCs on the LAN using the
Dynamic Host Configuration Protocol (DHCP). This feature greatly simplifies configuration
of PCs on your local network.
• DNS Proxy
When DHCP is enabled and no DNS addresses are specified, the modem router provides its
own address as a DNS server to the attached PCs. The modem router obtains actual DNS
addresses from the ISP during connection setup and forwards DNS requests from the LAN.
• Classical IP (RFC 1577)
Some Internet service providers, in Europe for example, use Classical IP in their ADSL
services. In such cases, the modem router is able to use the Classical IP address from the ISP.
• PPP over Ethernet (PPPoE)
PPP over Ethernet is a protocol for connecting remote hosts to the Internet over an ADSL
connection by simulating a dial-up connection. This feature eliminates the need to run a login
program such as EnterNet or WinPOET on your computer.
• PPP over ATM (PPPoA)
PPP over ATM is a protocol for connecting remote hosts to the Internet over an ADSL
connection by simulating an ATM connection.

v1.0, September 2006
Reference Manual for the Integrated ADSL Modem and Wireless Router with Voice, Mode l
• Dynamic DNS
Dynamic DNS services allow remote users to find your network using a domain name when
your IP address is not permanently assigned. The modem router contains a client that can
connect to many popular Dynamic DNS services to register your dynamic IP address.
• Universal Plug and Play (UPnP)
UPnP is a networking architecture that provides compatibility between networking
technologies. UPnP compliant routers provide broadband users at home and small businesses
with a seamless way to participate in online games, videoconferencing and other peer-to-peer
services.
Virtual Private Networking (VPN)
The Integrated ADSL Modem Wireless Router with Voice provides a secure encrypted connection
between your local area network (LAN) and remote networks or clients. It includes the following
VPN features:
• Supports 5 VPN connections.
• Supports industry standard VPN protocols
The Integrated ADSL Modem Wireless Router with Voice supports standard Manual or IKE
keying methods, standard MD5 and SHA-1 authentication methods, and standard DES and
3DES encryption methods. It is compatible with many other VPN products.
• Supports 3DES encryption for maximum security.
• VPN Wizard based on VPNC recommended settings.
Auto Sensing and Auto Uplink™ LAN Ethernet Connections
With its internal 4-port 10/100 switch, the DG834GV can connect to either a 10 Mbps standard
Ethernet network or a 100 Mbps Fast Ethernet network. The local LAN ports are autosensing and
capable of full-duplex or half-duplex operation.
The modem router incorporates Auto Uplink
automatically sense whether the Ethernet cable plugged into the port should have a ‘normal’
connection such as to a computer or an ‘uplink’ connection such as to a switch or hub. That port
will then configure itself to the correct configuration. This feature also eliminates the need to
worry about crossover cables, as Auto Uplink will accommodate either type of cable to make the
right connection.

Chapter 3
Wireless Configuration
This chapter describes how to configure the wireless features of your Integrated ADSL Modem
and Wireless Router with Voice, Model DG834GV.
Considerations for a Wireless Network
In planning your wireless network, you should consider the level of security required. You should
also select the physical placement of your modem router in order to maximize the network speed.
To ensure proper compliance and compatibility between similar products in your area, the
operating channel and region must be set correctly.
Observe Performance, Placement, and Range Guidelines
The operating distance or range of your wireless connection can vary significantly bas ed on the
physical placement of the wireless firewall. The latency, data throughput performance, and
notebook power consumption also vary depending on your configuration choices.
Note: Failure to follow these guidelines can result in significant performance degradation
or inability to wirelessly connect to the router. For complete range/performance
specifications, please see Appendix A, “Technical Specifications”.
For best results, place your firewall:
• Near the center of the area in which your computers will operate
• In an elevated location such as a high shelf where the wirelessly connected computers have
line-of-sight access (even if through walls)
• Away from sources of interference, such as computers, microwaves, and cordless phones
• With the Antenna tight and in the upright position
• Away from large metal surfaces
Wireless Configuration 3-1
v1.0, September 2006
Reference Manual for the Integrated ADSL Modem and Wireless Router with Voice, Model
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.
Implement Appropriate Wireless Security
Note: 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 of 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 Integrated ADSL Modem Wireless Router with Voice provides
highly effective security features which are covered in detail in this chapter. Deploy the security
features appropriate to your needs.
Figure 3-1
There are several ways you can enhance the security of your wireless network:
• Restrict Access Based on MAC Address. You can allow only trusted PCs to connect so that
unknown PCs cannot wirelessly connect to the DG834GV. Restricting access by MAC
address adds an obstacle against unwanted access to your network, but the data broadcast over
the wireless link is fully exposed.
• Turn Off the Broadcast of the Wireless Network Name SSID. If you disable broadcast of
the SSID, only devices that have the correct SSID can connect. This nullifies wireless network
‘discovery’ feature of some products, such as Windows XP, but the data is still exposed.
3-2 Wireless Configuration
v1.0, September 2006

• WEP. Wired Equivalent Privacy (WEP) data encryption provides data security. WEP Shared
Key authentication and WEP data encryption will block all but the most determined
eavesdropper.
• WPA. Wi-Fi Protected Access (WPA) data encryption provides data security. The very strong
authentication along with dynamic per frame re-keying of WPA make it virtually impossible to
compromise. Because this is a new standard, wireless device driver and software availability
may be limited.
Understanding Wireless Settings
To configure the Wireless interface of your modem router, click the Wireless Settings link in the
Setup section of the main menu. The Wireless Settings menu will appear, similar to that shown
below:
Figure 3-2
Wireless Configuration 3-3
v1.0, September 2006
Reference Manual for the Integrated ADSL Modem and Wireless Router with Voice, Model
The following parameters are in the Wireless Settings menu:
• Wireless Network.
— Name (SSID). The Service Set ID, also known as the wireless network name. Enter a
value of up to 32 alphanumeric characters. The same Name (SSID) must be assigned to all
wireless devices in your network. The default SSID is NETGEAR, but NETGEAR
strongly recommends that you change your network Name to a different value.
Note: This value is case sensitive. For example, Wireless is not the same as
wireless.
— Region. Select your country/region from the drop-down list. This field displays the region
of operation for which the wireless interface is intended.
Note: In the USA, the Region is preset according to regulatory requirements and
cannot be changed. In other areas, you can and must set the Region. It may
not be legal to operate the wireless access point in a region other than one
of those identified in this field.
— Channel. This field determines which operating frequency will be used. It should not be
necessary to change the wireless channel unless you notice interference problems with
another nearby access point.
— Mode. The default is "g & b", which allows both "g" and "b" wireless stations to access
this device. “g only” allows only 802.11g wireless stations to be used. “b only” allows
802.11b wireless stations; 802.1 1g wireless stations can still be used if they can operate in
802.11b mode.
• Wireless Access Point.
— Enable Wireless Access Point. This field lets you turn off or turn on the wireless access
point built in to the modem router. The wireless icon on the front of the modem router will
also display the current status of the Wireless Access Point to let you know if it is disabled
or enabled. The wireless access point must be enabled to allow wireless stations to access
the Internet.
— Allow Broadcast of Name (SSID). If enabled, the SSID is broadcast to all Wireless
Stations. Stations which hav e no SSID (o r a "n ull" value) can then adopt the correct SSID
for connections to this Access Point.
3-4 Wireless Configuration
v1.0, September 2006
Reference Manual for the Integrated ADSL Modem and Wireless Router with Voice, Mode l
— Wireless Isolation. If enabled, Wireless S tations will not be able to communicate with
each other or with Stations on the wired network. This feature should normally be
disabled.
• Wireless Station Access List.
— By default, any wireless computer that is configured with the correct wireless network
name or SSID will be allowed access to your wireless network. For increased security , you
can restrict access to the wireless network to only specific computers based on their MAC
addresses. Click Setup Access List to display the Wireless Station Access List menu.

You can select the following WEP options:
Authentication Type
• Open: the DG834GV does not perform any authentication.
• Shared: WEP shared key authentication. For a full explanation of WEP shared key,
see “Wireless Communications” in Appendix B.
Encryption Strength
• If Shared or Open Network Authentication is enabled, you can choose 64- or 128-bit
WEP data encryption.
Note: With Open Network Authentication and 64- or 128-bit WEP Data Encryption, the
DG834GV does perform 64- or 128-bit data encryption but does not perform any
authentication.
Security Encryption (WEP) Key
These key values must be identical on all wireless devices in your network (key 1 must
be the same for all, key 2 must be the same for all, and so on).
The DG834GV provides two methods for creating WEP encryption keys:
• Passphrase. These characters are case sensitive. Enter a word or group of printable
characters in the Passphrase box and click the Generate button.
Note: Not all wireless adapters support passphrase key generation.
• Manual. These values are not case sensitive.
64-bit WEP: enter 10 hexadecimal digits (any combination of 0-9, a-f, or A-F).
128-bit WEP: enter 26 hexadecimal digits (any combination of 0-9, a-f, or A-F).
