Regulatory Approvals
FCC Statement
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation.
This equipment generates, uses and can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver
is connected.
Consult the dealer or an experienced radio/TV technician for help.
To assure continued compliance, any changes or modifications not expressly approved by the
party responsible for compliance could void the user's authority to operate this equipment.
(Example - use only shielded interface cables when connecting to computer or peripheral
devices).
FCC Radiation Exposure Statement
This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with a minimum distance of 20
centimeters between the radiator and your body.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions:
(1) This device may not cause harmful interference, and
(2) This device must accept any interference received, including interference that may cause
undesired operation.
This transmitter must not be co-located or operating in conjunction with any other antenna or
transmitter.
The antennas used for this transmitter must be installed to provide a separation distance of at
least 20 cm from all persons and must not be co-located or operating in conjunction with any
other antenna or transmitter.
Channel
The Wireless Channel sets the radio frequency used for communication.
•Access Points use a fixed Channel. You can select the Channel used. This allows you to
choose a Channel which provides the least interference and best performance. In the USA
and Canada, 11 channel are available. If using multiple Access Points, it is better if adjacent
Access Points use different Channels to reduce interference.
• In "Infrastructure" mode, Wireless Stations normally scan all Channels, looking for an
Access Point. If more than one Access Point can be used, the one with the strongest
signal is used. (This can only happen within an ESS.)
• If using "Ad-hoc" mode (no Access Point), all Wireless stations should be set to use the
same Channel. However, most Wireless stations will still scan all Channels to see if there
is an existing "Ad-hoc" group they can join.
Note:This equipment marketed in USA is restricted by firmware to only operate on 2.4G channel 1-11

Chapter 2
Wireless Configuration
This chapter describes how to configure the wireless features of your DG834N RangeMaxTM
NEXT Wireless ADSL2+ Modem Router.
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 wireless modem router in order to maximize the
network speed. For further information, refer to “Internet Networking and TCP/IP Addressing:” in
Appendix B.
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
• Away from large metal surfaces
Wireless Configuration 2-1
v1.0, May 2005
DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual
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 RangeMax NEXT Wireless ADSL2+ Modem Router provides
highly effective security features which are covered in detail in this chapter. Deploy the sec urity
features appropriate to your needs.

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 DG834N. 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.
• 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. This data encryption mode has been superseded by WPA-PSK and WPA2-PSK,
and is only available as an option if the Wireless Mode is restricted to 801.11b and 802.11g
wireless stations.
• WPA-PSK (TKIP) + WPA2-PSK (AES). 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 relatively new standard,
wireless device driver and software availability may be limited.

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.
This value is case sensitive. For example, Wireless is not the same as wireless.
• Region. Select your region from the drop-down list. This field displays the region of operation
for which the wireless interface is intended. It may not be legal to operate the wireless modem
router in a region other than the region shown here.
• Channel. This field determines which operating frequency will be used. If you select the
AUTO setting, the RangeMax NEXT Wireless ADSL2+ Modem Router will periodically
survey the wireless environment to ensure that it is using the clearest channel. If a clearer
channel is available, it may automatically switch channels.
Note: After the router switches channels, there may be a slight delay while your
wireless computers reconnect to the router. If you want to avoid this
possibility, leave channel selection on a fixed channel setting.
• Mode.
— "g & b" allows older 802.11g" and 802.11b wireless stations to access this device. You
may want to select this mode if you have a wireless station that is using WEP security and
does not support WPA-PSK or WPA2-PSK.
— “Up to 130Mbps” allows wireless stations that support speeds up to 130 Mbps. In this
case, the router will transmit two streams with different data concurrently on the same
channel. You may want to select this mode to restrict channel bandwidth in order to
minimize interference with the data transmissions of other access points and wireless
stations.
— “Up to 270Mbps” means all 802.11g, 802.11b, and faster Pre-N and 802.11N wireless
stations can be used. This mode expands the channel bandwidth from 20 MHz to 40 MHz
to achieve the 270 Mbps rate. The router selects channel expansion on a frame-by-frame
basis to avoid interference with the data transmissions of other access points or wireless
stations. This mode is the fastest mode and, since it is compatible with older wireless
stations, it is recommended and is the default.

Wireless Access Point.
• Enable Wireless Access Point. This field lets you turn off or turn on the wireless access point
built in to the wireless modem router. The wireless icon on the front of the wireless 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 have no SSID (or a "null" value) can then adopt the correct SSID for
connections to this Access Point.
• Wireless Isolation. If enabled, Wireless Stations 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.
