Wireless Configuration
This chapter describes how to configure the wireless features of your DG834N RangeMaxTM
NEXT Wireless ADSL2+ Modem Router.This chapter includes:
•“Considerations for a Wireless Network”
•“Understanding Wireless Settings”
•“Understanding Wireless Security”
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 to maximize the network speed. For
further information, see the online documentation that you can access from “TCP/IP Networking
Basics” 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 based on the
physical placement of the wireless firewall. The latency, data throughput performance, and
notebook power consumption also vary depending on your configuration choices.
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)
Note: Failure to follow these guidelines can result in significant performance degradation
or inability to wirelessly connect to the router. For complete range and
performance specifications, see Appendix A, “Technical Specifications.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
2-2 Wireless Configuration
v1.0, April 2008
• Away from sources of interference, such as computers, microwaves, and cordless phones
• Away from large metal surfaces
The time it takes to establish a wireless connection can vary depending on both your security
settings and placement. Wired Equivalent Privacy (WEP) connections can take slightly longer to
establish. Also, WEP encryption can consume more battery power on a notebook computer.
Implement Appropriate Wireless Security
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 modem router provides highly effective security features, which are
covered in detail in this chapter. Deploy the security features appropriate to your needs.
Note: Indoors, computers can connect over wireless networks at a range of several
hundred feet. Such distances can allow for others outside of your immediate area to
access your network.

Wireless Configuration 2-3
v1.0, April 2008
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 modem router. 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 block all but the most determined eavesdropper.
This data encryption mode has been superseded by WPA-PSK and WPA2-PSK, and is
available as an option only if the wireless mode is restricted to 802.11b and 802.11g wireless
stations.
•WPA-802.1x, WPA2-802.1x. Wi-Fi Protected Access (WPA) with user authentication
implemented using IEE 802.1x and RADIUS servers. This option is available only if the
wireless mode is restricted to 802.11b and 802.11g wireless stations.
•WPA-PSK (TKIP) + WPA2-PSK (AES). Wi-Fi Protected Access (WPA) using a pre-shared
key to perform authentication and generate the initial data encryption keys. The very strong
authentication along with dynamic per frame re-keying of WPA makes it virtually impossible
to compromise.

Wireless Net-
work
Name (SSID) The SSID is also known as the wireless network name.
Enter a 32-character (maximum) name in this field. This
field is case-sensitive. The default SSID is NETGEAR, but
NETGEAR strongly recommends that you change your net-
work name to a different value.
In a setting in which there is more than one wireless net-
work, different wireless network names provide a means for
separating the traffic. Any device you that want to let partici-
pate in a wireless network must use the SSID.
Region The location where the firewall is used. Select your region
from the drop-down list. It might not be legal to operate the
modem router in a region other than the region shown here.
Channel The wireless channel used by the gateway. If you select the
AUTO setting, the modem router will periodically survey the
wireless environment to ensure that it is using the clearest
channel. If a clearer channel is available, it might automati-
cally switch channels.
Do not change the wireless channel unless you experience
interference (shown by lost connections or slow data trans-
fers). If this happens, you might need to experiment with dif-
ferent channels to see which is the best.
Mode • Up to 270Mbps means that all 802.11g, 802.11b, and
faster Draft-N 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 is compatible with older wireless stations.
•Up to 130Mbps allows wireless stations that support
speeds up to 130 Mbps. In this case, the router transmits
two streams with different data concurrently on the same
channel. This mode restricts channel bandwidth to
minimize interference with the data transmissions of other
access points and wireless stations. It is the default
setting.
•g & b allows older 802.11g and 802.11b wireless stations
to access this device. You might 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.

Enable Wireless Access
Point
Selected by default, this setting enables the wireless radio,
which allows the modem router to work as a wireless
access point.
Turning off the wireless radio can be helpful for configura-
tion, network tuning, or troubleshooting.
The Wireless LED on the front of the modem router displays
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 Name
(SSID).Selected by default, the modem router 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.
Wireless Isolation This feature is disabled by default. If it is enabled, wireless
stations cannot communicate with each other or with sta-
tions on the wired network.
Wireless Sta-
tion Access List
Turn Access Control On Access control is disabled by default so that any computer
configured with the correct wireless network name or SSID
can access to your wireless network. For increased secu-
rity, you can restrict access to the wireless network to only
specific computers based on their MAC addresses. See
“Restricting Wireless Access Based on the Wireless Station
Access List.”

How to Set Up and Test Basic Wireless Connectivity
Follow these instructions to set up and test basic wireless connectivity. Once you have established
basic wireless connectivity, you can enable security settings appropriate to your needs.
1. Log in to the modem router firewall at its default LAN address of http://192.168.0.1 with its
default user name of admin and default password of password, or using whatever LAN
address and password you have set up.
2. Select the Wireless Settings in the main menu.
3. Choose a suitable descriptive name for the wireless network name (SSID). In the SSID field,
enter a value of up to 32 alphanumeric characters. The default SSID is NETGEAR.
4. Select the region in which the wireless interface will operate.
Security Options None Wireless security is not used.
WPA-PSK (TKIP) +
WPA2-PSK (AES)
WPA Pre-Shared-Key (Wi-Fi Protected Access Pre-Shared
Key) uses a pre-shared key to perform the authentication
and generate the initial data encryption keys. Then, it
dynamically varies the encryption key. WPA-PSK (TKIP)
implements most of the IEEE 802.11i standard and is
designed to work with all wireless network interface cards,
but not all wireless access points. WPA2 implements the full
standard, but does not work with some older network cards.
See “How to Configure WPA-PSK and WPA2-PSK
Security.”
WEP This mode is available only if the g and b wireless mode is
selected. This mode has been superseded by WPA-PSK
and WPA2-PSK, which should be selected if possible. See
“How to Configure WEP.”
WPA-802.1x This mode is available only if the g and b wireless mode is
selected. User authentication is implemented using 802.1x
and RADIUS servers. See “How to Configure WPA-802.1x
and WPA2-802.1x.”
Note: The SSID of any wireless access adapters must match the SSID you specify in
the modem router. If they do not match, you will not get a wireless connection.

5. Set the channel if necessary. The default channel is 6.
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
wireless router or access point. Select a channel that is not being used by any other wireless
networks within several hundred feet of your modem router. If you set the channel to Auto,
the modem router will find the clearest channel for you. However, if that channel becomes
noisy, there might be a delay in wireless communications while the modem router searches for
a new channel. For more information about the wireless channel frequencies, see the online
document that you can access from “Preparing Your Network” in Appendix B.
6. For initial configuration and test, leave the Wireless Card Access List set to allow everyone
access by making sure that Turn Access Control On is not selected in the Wireless Station
Access List. In addition, leave the encryption strength set to None.
7. Click Apply to save your changes.
8. Configure and test your computers for wireless connectivity.
Program the wireless adapter of your computers to have the same SSID and channel that you
specified in the router. Check that they have a wireless link and can obtain an IP address by
DHCP from the modem router.
Once your computers have basic wireless connectivity to the modem router, you can configure the
advanced wireless security functions of the firewall.
Understanding Wireless Security
Indoors, computers can connect over 802.11n wireless networks at a range that can exceed
300 feet. Such distances can allow for others outside 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 DG834N modem router provides highly effective security features
that are covered in detail in this section. Deploy the security features appropriate to your needs.
Note: If you are configuring the firewall from a wireless computer and you change
the firewall’s SSID, channel, or security settings, you will lose your wireless
connection when you click Apply. You must then change the wireless settings
of your computer to match the firewall’s new settings.

Wireless Configuration 2-9
v1.0, April 2008
Restricting Wireless Access to Your Network
By default, any wireless PC that is configured with the correct SSID can access your wireless
network. For increased security, the modem router provides several ways to restrict wireless access
to your network. You can do the following:
• Turn off wireless connectivity completely.
• Restrict access based on the wireless network name (SSID).
• Restrict access based on the Wireless Card Access List.
These options are discussed in the following sections.
Restricting Access to Your Network by Turning Off Wireless Connectivity
You can completely turn off the wireless portion of the modem router. For example, if you use
your notebook computer to wirelessly connect to your router and you take a business trip, you can
turn off the wireless portion of the router while you are traveling. Other members of your
household who use computers connected to the router through Ethernet cables can still use the
router.
Restricting Wireless Access Based on the Wireless Network Name (SSID)
The modem router can restrict wireless access to your network by not broadcasting the wireless
network name (SSID). However, by default, this feature is turned off. If you turn this feature on,
wireless devices do not “see” your modem router. You must configure your wireless devices to
match the wireless network name (SSID) you specify in the modem router.
Restricting Wireless Access Based on the Wireless Station Access List
This list determines which wireless hardware devices will be allowed to connect to the modem
router.
To restrict access based on MAC addresses:
1. Log in to the modem router at its default LAN address of http://192.168.0.1 with its default
user name of admin and default password of password, or using whatever LAN address and
password you have set up.
Warning: The SSID of any wireless access adapters must match the SSID you specify in
the modem router. If they do not match, you will not get a wireless
connection.

3. Select the Turn Access Control On check box to enable the restricting of wireless computers
by their MAC addresses.
4. If the wireless station is currently connected to the network, you can select it from the
Available Wireless Stations list. Click Add to add the station to the Trusted Wireless Stations
list.
5. If the wireless station is not currently connected, you can enter its address manually. Enter the
MAC address of the authorized computer. The MAC address is usually printed on the wireless
card, or it might appear in the modem router’s DHCP table. The MAC address is
12 hexadecimal digits.
Click Add to add your entry. You can add several stations to the list. When you are finished
adding stations, click Apply.

6. Make sure the Turn Access Control On check box is selected, and then click Apply.
Now, only devices on this list will be allowed to wirelessly connect to the modem router. This
prevents unauthorized access to your network.
How to Configure WPA-PSK and WPA2-PSK Security
A high-performance client such as the NETGEAR WN511B must connect to the modem router
using WPA2-PSK to achieve maximum performance. Wireless clients that connect to the modem
router using WPA-PSK run at no more than 802.11g speed. This option allows wireless clients to
use either encryption method.
To configure WPA-PSK + WPA2-PSK:
1. Log in at the default LAN address of http://192.168.0.1, with the default user name of admin
and default password of password, or using whatever LAN address and password you have
set up.
2. Select Wireless Settings below Setup in the main menu of the modem router.
3. Select the WPA-PSK [TKIP] + WPA2-PSK [AES] radio button. The Wireless Settings
screen expands to include the WPA-PSK.
4. Enter the pre-shared key in the Passphrase field using between 8 and 63 characters.
5. Click Apply to save your settings.
If the wireless network mode is set to g and b, you have the option of selecting WPA-PSK only,
WPA2-PSK only, WPA-802.1x, and WPA2-802.1x. For details about the 802.1x authentication
options, see “How to Configure WPA-802.1x and WPA2-802.1x” on page 2-14.
Note: If you are configuring the modem router from a wireless computer whose
MAC address is not in the Trusted Wireless Stations list, and you select trusted
wireless stations only, you will lose your wireless connection when you click
Apply. You must then access the modem router from a wired computer to
make any further changes.
Note: Not all wireless adapters support WPA or WPA2. Furthermore, client software is
required on the client. Windows XP and Windows 2000 with Service Pack 3 do
include the client software that supports WPA. Nevertheless, the wireless adapter
hardware and driver must also support WPA. Consult the product document for
your wireless adapter and WPA client software for instructions on configuring
WPA settings.

Choosing Alternative Authentication and Encryption Methods
Alternative authentication and encryption methods are available only if you select g and b as the
wireless network mode in the Wireless Settings screen. These options will result in a performance
impact since wireless communications will be limited to the 802.11g data rate.
Restricting wireless access prevents intruders from connecting to your network. However, the
wireless data transmissions are still vulnerable to snooping. Using the data encryption settings
described in this section will prevent a determined intruder from eavesdropping on your wireless
data communications. Also, if you are using the Internet for such activities as purchases or
banking, those Internet sites use another level of highly secure encryption called SSL. You can tell
if a web site is using SSL because the Web address begins with HTTPS rather than HTTP.
How to Configure WEP
Wired Equivalent Privacy (WEP) security is the most basic and simplest form of wireless security.
It is the most often used, but least secure of the available options. WEP Shared Key authentication
and WEP data encryption block all but the most determined eavesdropper. This data encryption
mode has been superseded by WPA-PSK and WPA2-PSK.
To configure WEP data encryption:
1. Log in to the modem router at its default LAN address of http://192.168.0.1 with its default
user name of admin and default password of password, or using whatever LAN address and
password you have set up.
2. Select Wireless Settings in the main menu.
3. In the Security Options section of the screen, select WEP. The WEP Security Encryption
section displays.
Note: The WEP security option is available only if the wireless network mode is set

encryption keys. These values must be identical on all computers and access points in your
network.
• Automatic. Enter a word or group of printable characters in the Passphrase field and click
Generate. The four key boxes are automatically populated with key values.
• Manual. The number of hexadecimal digits that you must enter depends on the encryption
strength setting:
– For 64-bit WEP, enter 10 hexadecimal digits (any combination of 0–9, a–f, or A–F).
– For 128-bit WEP, enter 26 hexadecimal digits (any combination of 0–9, a–f, or A–F).
7. Select the radio button for the key you want to make active.
Be sure that you clearly understand how the WEP key settings are configured in your wireless
adapter. Wireless adapter configuration utilities such as the one included in Windows XP
allow entry of only one key, which must match the default key you set in the modem router.

How to Configure WPA-802.1x and WPA2-802.1x
This version of WPA requires the use of a RADIUS server for authentication. Each user (wireless
client) must have a user login on the RADIUS server, and the modem router must have a client
login on the RADIUS server. Data transmissions are encrypted using a key that is automatically
generated.
1. Log in to the modem router at its default LAN address of http://192.168.0.1 with its default
user name of admin and default password of password, or using whatever LAN address and
password you have set up.
2. Select the wireless settings link in the main menu of the modem router.
3. In the Security Options section of the screen, select WPA-802.1x or WPA2-802.1x.
4. In the Radius Server Name/IP Address field, enter the name or IP address of the RADIUS
server on your LAN. This is a required field.
5. In the Radius Port field, enter the port number used for connections to the RADIUS server.
6. In the Radius Shared Key field, enter the value that you want to use for the RADIUS shared
key. This key enables the modem router to log in to the RADIUS server and must match the
client login value used on the RADIUS server.
Note: When configuring the modem router from a wireless computer, if you specify WEP
settings, you will lose your wireless connection when you click Apply. You must
then either configure your wireless adapter to match the modem router WEP
settings or access the modem router from a wired computer to make any further
changes.
Note: The WPA-802.1x and WPA2-802.1x security options are available only if the
wireless network mode is set to g and b.

Protecting Access to Your Wireless Modem Router
For security reasons, the modem router has its own user name and password. Also, after a period
of inactivity for a set length of time, the administrator login automatically disconnects. When
prompted, enter admin for the modem router user name and password for the modem router
password. You can use the following procedures to change the modem router’s password and the
period for the administrator’s login time-out.
NETGEAR recommends that you change this password to a more secure password. The ideal
password should contain no dictionary words from any language, and should be a mixture of both
upper case and lower case letters, numbers, and symbols. Your password can be up to 30
characters.
Note: The user name and password are not the same as any other user name or password
your might use to log in to your Internet connection.

Configuring Basic Firewall Services
Basic firewall services that you can configure include access blocking and scheduling of firewall
security. These topics are presented in the following sections.
Blocking Keywords, Sites, and Services
The modem router provides a variety of options for blocking Internet-based content and
communications services. With its content filtering feature, the RangeMax NEXT Wireless
ADSL2+ Modem Router prevents objectionable content from reaching your PCs. The modem
router allows you to control access to Internet content by screening for keywords within Web
addresses. Key content filtering options include:
• Keyword blocking of HTTP traffic.
• Outbound service blocking. Limits access from your LAN to Internet locations or services that
you specify as off-limits.
• Denial of service (DoS) protection. Automatically detects and thwarts denial of service (DoS)
attacks such as Ping of Death, SYN flood, LAND Attack, and IP spoofing.
• Blocking unwanted traffic from the Internet to your LAN.
The following section explains how to configure your modem router to perform these functions.
How to Block Keywords and Sites
The modem router allows you to restrict access to Internet content based on functions such as Web
addresses and Web address keywords.
1. Log in to the modem router at its default LAN address of http://192.168.0.1 with its default
user name of admin and default password of password, or using whatever password and LAN
address you might have previously set for the modem router.

2. In the main menu, under Security, select Block Sites to display the following screen
.
3. To enable keyword blocking, select one of the following:
•Per Schedule. Turn on keyword blocking according to the settings in the Schedule screen.
•Always. Turn on keyword blocking all the time, independent of the Schedule screen.
4. Enter a keyword or domain in the Keyword field, click Add Keyword, and then click Apply.
Some examples of keyword application follow:
• If the keyword XXX is specified, the URL http://www.badstuff.com/xxx.html is blocked.
• If the keyword .com is specified, only websites with other domain suffixes (such as .edu or
.gov) can be viewed.
• Enter a period (.) as to block all Internet browsing access.
Up to 32 entries are supported in the Keyword list.
5. To delete a keyword or domain, select it from the list, click Delete Keyword, and then click
Apply.
6. To specify a trusted user, enter that computer’s IP address in the Trusted IP Address field,
and click Apply.

Protecting Your Network 3-5
v1.0, April 2008
You can specify one trusted user, which is a computer that will be exempt from blocking and
logging. Since the trusted user will be identified by an IP address, you should configure that
computer with a fixed IP address.
7. Click Apply to save your settings.
Firewall Rules
Firewall rules block or allow specific traffic passing through from one side of the router to the
other. Inbound rules (WAN to LAN) restrict access by outsiders to private resources, selectively
allowing only specific outside users to access specific resources. Outbound rules (LAN to WAN)
determine what outside resources local users can have access to.
A firewall has two default rules, one for inbound traffic and one for outbound. The default rules of
the modem router are:
• Inbound. Block all access from outside except responses to requests from the LAN side.
• Outbound. Allow all access from the LAN side to the outside.
You can define additional rules that will specify exceptions to the default rules. By adding custom
rules, you can block or allow access based on the service or application, source or destination IP
addresses, and time of day. You can also choose to log traffic that matches or does not match the
rule you have defined.
You can change the order of precedence of rules so that the rule that applies most often takes effect
first. See “Order of Precedence for Rules” on page 3-11 for more details.
To access the rules configuration of the modem router, select Firewall Rules on the main menu,
and then click Add for either an outbound or inbound service. The Firewall Rules screen displays.

• To edit an existing rule, select its button on the left side of the table, and click Edit.
• To delete an existing rule, select its button on the left side of the table, and click Delete.
• To move an existing rule to a different position in the table, select its button on the left side of
the table, and click Move. At the prompt, enter the number of the desired new position and
click OK.
Inbound Rules (Port Forwarding)
Because the modem router uses Network Address Translation (NAT), your network presents only
one IP address to the Internet, and outside users cannot directly address any of your local
computers. However, by defining an inbound rule you can make a local server (for example, a Web
server or game server) visible and available to the Internet. The rule tells the modem router to
direct inbound traffic for a particular service to one local server based on the destination port
number. This is also known as port forwarding.
Figure 3-4
Note: Some residential broadband ISP accounts do not allow you to run any server
processes (such as a Web or FTP server) from your location. Your ISP might
periodically check for servers and might suspend your account if it discovers any
active services at your location. If you are unsure, refer to the acceptable use policy
of your ISP.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
Protecting Your Network 3-7
v1.0, April 2008
Remember that allowing inbound services opens holes in your firewall. Enable only those ports
that are necessary for your network. Following are two application examples of inbound rules.
Inbound Rule Example: A Local Public Web Server
If you host a public Web server on your local network, you can define a rule to allow inbound Web
(HTTP) requests from any outside IP address to the IP address of your Web server at any time of
day. This rule is shown in the following figure:
The settings are:
•Service. From this list, select the application or service to be allowed or blocked. The list
already displays many common services, but you are not limited to these choices. Use the
Services screen to add any additional services or applications that do not already appear. See
“How to Define Services” on page 3-12.
•Action. Choose how you want this type of traffic to be handled. You can block or allow
always, or you can block or allow according to the schedule you have defined in the Schedule
screen.
•Send to LAN Server. Enter the IP address of the computer or server on your LAN that will
receive the inbound traffic covered by this rule.
Figure 3-5
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
3-8 Protecting Your Network
v1.0, April 2008
•WAN Users. These settings determine which packets are covered by the rule, based on their
source (WAN) IP address. Select the option that you want:
–Any: All IP addresses are covered by this rule.
–Address range: If this option is selected, you must fill in the Start and Finish fields.
–Single address: Enter the required address in the Start field.
•Log. You can select whether the traffic will be logged. The choices are:
–Never. No log entries will be made for this service.
–Always. Any traffic for this service type will be logged.
–Match. Traffic of this type that matches the settings and action will be logged.
–Not match. Traffic of this type that does not match the settings and action will be logged.
Inbound Rule Example: Allowing Video conferencing
If you want to allow incoming video conferencing to be initiated from a restricted range of outside
IP addresses, such as from a branch office, you can create an inbound rule. In the example shown
in the following figure, CU-SeeMe connections are allowed only from a specified range of
external IP addresses. In this case, we have also specified logging of any incoming CU-SeeMe
requests that do not match the allowed settings.
Figure 3-6
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
Protecting Your Network 3-9
v1.0, April 2008
Considerations for Inbound Rules
• If your external IP address is assigned dynamically by your ISP, the IP address might change
periodically as the DHCP lease expires. Consider using the Dynamic DNS screen so that
external users can always find your network.
• If the IP address of the local server computer is assigned by DHCP, it might change when the
computer is rebooted. To avoid this, use the Reserved IP address feature in the LAN IP Setup
screen to keep the computer’s IP address constant.
• Local computers must access the local server using the computer’s local LAN address
(192.168.0.11 in the example in the previous figure). Attempts by local computers to access
the server using the external WAN IP address will fail.
Outbound Rules (Service Blocking)
The modem router allows you to block the use of certain Internet services by computers on your
network. This is called service blocking or port filtering. You can define an outbound rule to block
Internet access from a local computer based on the following:
• IP address of the local computer (source address)
• IP address of the Internet site being contacted (destination address)
•Time of day
• Type of service being requested (service port number)
Following is an application example of outbound rules.
Outbound Rule Example: Blocking Instant Messenger
If you want to block Instant Messenger usage by employees during working hours, you can create
an outbound rule to block that application from any internal IP address to any external address
according to the schedule that you create in the Schedule screen.You can specify that the modem
router logs any attempt to use Instant Messenger during this blocked period. You can also open or
close Instant Messenger ports: see the Firewall Rules screen in the “Order of Precedence for
Rules” section on page 3-11.

–Not match. Traffic of this type that does not match the settings and action will be logged.
Order of Precedence for Rules
As you define new rules, they are added to the tables in the Firewall Rules screen, as shown in the
following figure:
For any traffic attempting to pass through the firewall, the packet information is subjected to the
rules in the order shown in the Rules table, beginning at the top and proceeding to the default rules
at the bottom. In some cases, the order of precedence of two or more rules might be important in
determining the disposition of a packet. The Move button allows you to relocate a defined rule to a
new position in the table.

The Firewall Rules screen also lets you easily open or close Instant Messenger ports:
1. Under Instant Messaging (IM) Ports, select a radio button:
•Close IM Ports. Specifies to disable instant messaging traffic.
•Open IM Ports. Specifies to enable instant messaging traffic. IM ports are open by
default.
2. Click Apply to save your changes.
Services
Services are functions performed by server computers at the request of client computers. For
example, Web servers serve Web pages, time servers serve time and date information, and game
hosts serve data about other players’ moves. When a computer on the Internet sends a request for
service to a server computer, the requested service is identified by a service or port number. This
number appears as the destination port number in the transmitted IP packets. For example, a packet
that is sent with destination port number 80 is an HTTP (Web server) request.
The service numbers for many common protocols are defined by the Internet Engineering Task
Force (IETF) and published in RFC1700, “Assigned Numbers.” Service numbers for other
applications are typically chosen from the range 1024 to 65535 by the authors of the application.
Although the modem router already holds a list of many service port numbers, you are not limited
to these choices. Use the following procedure to create your own service definitions.
How to Define Services
1. Log in to the modem router at its default LAN address of http://192.168.0.1 with its default
user name of admin, and default password of password, or using whatever password and
LAN address you have chosen for the modem router.

Chapter 5
Advanced Configuration
This chapter describes how to configure the advanced features of your DG834N RangeMaxTM
NEXT Wireless ADSL2+ Modem Router.
Configuring Advanced Security
The modem router provides a variety of advanced features, which are described in the following
sections:
•“Setting Up a Default DMZ Server”
•“Connecting Automatically, as Required”
•“Disabling Port Scan and DOS Protection”
•“Responding to a Ping on an Internet WAN Port”
•“Setting the MTU Size”
•“Disabling the SIP ALG”
•“Configuring LAN IP Settings”
•“Configuring DHCP”
•“Configuring LAN TCP/IP Settings”
•“Configuring Dynamic DNS”
•“Using Static Routes”
•“How to Configure Universal Plug and Play”
•“Building Wireless Bridging and Repeating Networks”
These features are discussed in the following sections.
Setting Up a Default DMZ Server
The default demilitarized zone (DMZ) server feature is helpful when you use some online games
and videoconferencing applications that are incompatible with NAT. The modem router is
programmed to recognize some of these applications and to work correctly with them, but there
are other applications that might not function well. In some cases, one local computer can run the
application correctly if that computer’s IP address is entered as the default DMZ server.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
5-2 Advanced Configuration
v1.0, April 2008
Incoming traffic from the Internet is usually discarded by the modem router unless the traffic is a
response to one of your local computers or a service that you have configured in the Ports screen.
Instead of discarding this traffic, you can have it forwarded to one computer on your network. This
computer is called the default DMZ server.
How to Configure a Default DMZ Server
To assign a computer or server to be a default DMZ server:
1. Log in to the modem router at its default LAN address of http://192.168.0.1 with its default
user name of admin and default password of password, or using whatever user name,
password, and LAN address you have chosen for the modem router.
2. In the main menu, under Advanced, click WAN Setup to display the following screen.
3. Select the Default DMZ Server check box.
Note: For security reasons, you should avoid using the default DMZ server feature. When
a computer is designated as the default DMZ server, it loses much of the protection
of the firewall, and is exposed to many exploits from the Internet. If compromised,
the computer can be used to attack your network.
Figure 5-1
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
Advanced Configuration 5-3
v1.0, April 2008
4. Type the IP address for that server.
5. Click Apply to save your changes.
Other WAN Options
The WAN Setup screen that is shown in Figure 5-1 also allows you perform the following tasks:
•Connecting Automatically, as Required
Usually, this option should be enabled, so that an Internet connection is made automatically,
whenever Internet-bound traffic is detected. If this causes high connection costs, you can
disable this setting.
If this setting is disabled, you must connect manually, using the screen that you access by
clicking the Connection Status button on the Status screen.
If you have an Always on connection, this setting has no effect.
•Disabling Port Scan and DOS Protection
The firewall protects your LAN against port scans and denial of service (DOS) attacks. This
protection should be disabled only in special circumstances.
•Responding to a Ping on an Internet WAN Port
If you want the modem router to respond to a ping from the Internet, select the Respond to
Ping on Internet WAN Port check box. This should be used only as a diagnostic tool, since it
allows your modem router to be discovered. Do not select this check box unless you have a
specific reason to do so.
•Setting the MTU Size
The normal MTU (Maximum Transmit Unit) value for most Ethernet networks is 1500 bytes,
or 1492 bytes for PPPoE connections. For some ISPs you might need to reduce the MTU. But
this is rarely required, and should not be done unless you are sure it is necessary for your ISP
connection.
•Disabling the SIP ALG
The Session Initiation Protocol (SIP) Application Level Gateway (ALG) is enabled by default
to optimize VoIP phone calls that use the SIP. The Disable SIP ALG check box allows you to
disable the SIP ALG. Disabling the SIP ALG might be useful when running certain
applications.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
5-4 Advanced Configuration
v1.0, April 2008
Configuring LAN IP Settings
The LAN IP Setup screen allows configuration of LAN IP services such as DHCP and RIP.
The modem router is shipped preconfigured to use private IP addresses on the LAN side, and to act
as a DHCP server. The modem router’s default LAN IP configuration is as follows:
• LAN IP address. 192.168.0.1
• Subnet mask. 255.255.255.0
These addresses are part of the Internet Engineering Task Force (IETF)–designated private address
range for use in private networks, and should be suitable in most applications. If your network has
a requirement to use a different IP addressing scheme, you can make those changes by opening the
LAN IP Setup menu.
Under Advanced in the main menu, select LAN IP Setup.
The LAN TCP/IP Setup settings are:
•IP Address. This is the LAN IP address of the modem router.
•IP Subnet Mask. This is the LAN subnet mask of the modem router. Combined with the IP
address, the IP subnet mask allows a device to know which other addresses are local to it, and
which must be reached through a gateway or modem router.
Figure 5-2
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
Advanced Configuration 5-5
v1.0, April 2008
•RIP Direction. Router Information Protocol (RIP) allows a modem router to exchange routing
information with other routers. The RIP Direction selection controls how the modem router
sends and receives RIP packets. Both is the default setting.
– When set to Both or Out Only, the modem router broadcasts its routing table periodically.
– When set to Both or In Only, the modem router incorporates the RIP information that it
receives.
– When set to None, the modem router does not send any RIP packets and ignores any RIP
packets received.
•RIP Version. This controls the format and the broadcasting method of the RIP packets that the
modem router sends. It recognizes both formats when receiving. By default, this is set for
RIP-1.
–RIP-1. This version is universally supported. RIP-1 is probably adequate for most
networks, unless you have an unusual network setup.
–RIP-2. This version carries more information. Both RIP-2B and RIP-2M send the routing
data in RIP-2 format.
•RIP-2B. This version uses subnet broadcasting.
•RIP-2M. This version uses multicasting.
Configuring DHCP
By default, the modem router functions as a Dynamic Host Configuration Protocol (DHCP) server,
allowing it to assign IP, DNS server, and default gateway addresses to all computers connected to
the modem router’s LAN. The assigned default gateway address is the LAN address of the router.
IP addresses are assigned to the attached PCs from a pool of addresses specified in this screen.
Each pool address is tested before it is assigned to avoid duplicate addresses on the LAN.
For most applications, the default DHCP and TCP/IP settings of the router are satisfactory. See the
online document that you can access from “TCP/IP Networking Basics” in Appendix B for an
explanation of DHCP and information about how to assign IP addresses for your network.
Note: If you change the LAN IP address of the modem router while connected through
the browser, you will be disconnected. You must then open a new connection to the
new IP address and log in again.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
5-6 Advanced Configuration
v1.0, April 2008
Use Router as DHCP Server
If another device on your network will be the DHCP server, or if you will manually configure the
network settings of all of your computers, clear the Use router as DHCP server check box.
Otherwise, leave it selected.
Specify the pool of IP addresses to be assigned by setting the starting IP address and ending IP
address. These addresses should be part of the same IP address subnet as the router’s LAN IP
address. Using the default addressing scheme, you should define a range between 192.168.0.2 and
192.168.0.254, although you might want to save part of the range for devices with fixed addresses.
The router delivers the following settings to any LAN device that requests DHCP:
• An IP address from the range you have defined
• Subnet mask
• Gateway IP address is the router’s LAN IP address
• Primary DNS server, if you entered a primary DNS address in the Basic Settings screen;
otherwise, the router’s LAN IP address
• Secondary DNS server, if you entered a secondary DNS address in the Basic Settings screen
• WINS server, short for Windows Internet Naming Service Server, determines the IP address
associated with a particular Windows computer. A WINS server records and reports a list of
names and IP address of Windows PCs on its local network. If you connect to a remote
network that contains a WINS server, enter the server’s IP address here. This allows your PCs
to browse the network using the Network Neighborhood feature of Windows.
How to Configure Reserved IP Addresses
When you specify a reserved IP address for a computer on the LAN, that computer will always
receives the same IP address each time it access the router’s DHCP server. Reserved IP addresses
should be assigned to servers that require permanent IP settings.
To reserve an IP address:
1. In the LAN IP Setup screen, click the Add button.
2. In the IP Address field, type the IP address to assign to the computer or server. Choose an
IP address from the router’s LAN subnet, such as 192.168.0.x.

4. Click Apply to enter the reserved address into the table.
To edit or delete a reserved address entry:
1. Click the button next to the reserved address that you want to edit or delete.
2. Click Edit or Delete.
Configuring LAN TCP/IP Settings
1. Log in to the router at its default LAN address of http://192.168.0.1 with its default user name
of admin and default password of password, or using whatever user name, password, and
LAN address you have chosen for the router.
2. In the main menu, under Advanced, click LAN IP Setup to display the following screen.
Tip: If the computer is already present on your network, you can copy its MAC
address from the Attached Devices screen and paste it here.
Note: The reserved address will not be assigned until the next time the computer
contacts the router’s DHCP server. Reboot the computer or access its IP
configuration and force a DHCP release and renew.

3. Enter the TCP/IP, DHCP, or reserved IP settings.
4. Click Apply to save your changes.
Configuring Dynamic DNS
If your network has a permanently assigned IP address, you can register a domain name and have
that name linked with your IP address by public Domain Name Servers (DNS). However, if your
Internet account uses a dynamically assigned IP address, you will not know in advance what your
IP address will be, and the address can change frequently. In this case, you can use a commercial
Dynamic DNS service that will allow you to register your domain to their IP address, and will
forward traffic directed at your domain to your frequently changing IP address.
The router contains a client that can connect to a Dynamic DNS service provider. To use this
feature, you must select a service provider and obtain an account with them. After you have
configured your account information in the router, whenever your ISP-assigned IP address
changes, your router automatically contacts your Dynamic DNS service provider, logs in to your
account, and registers your new IP address.
How to Configure Dynamic DNS
1. Log in to the modem router at its default LAN address of http://192.168.0.1 with its default
user name of admin and default password of password, or using whatever user name,
password, and LAN address you have chosen for the modem router.
2. In the main menu, under Advanced, select Dynamic DNS to display the following screen.
Figure 5-4
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
Advanced Configuration 5-9
v1.0, April 2008
3. Access the website of one of the Dynamic DNS service providers whose names appear in the
Service Provider drop-down list, and register for an account. For example, for dyndns.org, go
to www.dyndns.org.
4. Select the Use a dynamic DNS Service check box.
5. Select the name of your Dynamic DNS service provider.
6. Type the host name that your Dynamic DNS service provider gave you. The Dynamic DNS
service provider might call this the domain name. If your URL is myName.dyndns.org, then
your host name is myName.
7. Type the user name for your Dynamic DNS account.
8. Type the password (or key) for your Dynamic DNS account.
9. If your Dynamic DNS provider allows the use of wildcards in resolving your URL, you can
select the Use Wildcards check box to activate this feature. For example, the wildcard feature
causes *.yourhost.dyndns.org to be aliased to the same IP address as yourhost.dyndns.org.
10. Click Apply to save your configuration.
Using Static Routes
Static routes provide additional routing information to your router. Under normal circumstances,
the router has adequate routing information after it has been configured for Internet access, and
you do not need to configure additional static routes. You must configure static routes only for
unusual cases such as multiple routers or multiple IP subnets located on your network.
Static Route Example
As an example of when a static route is needed, consider the following case:
• Your primary Internet access is through a cable modem to an ISP.
• You have an ISDN router on your home network for connecting to the company where you are
employed. This router’s address on your LAN is 192.168.0.100.
• Your company’s network address is 134.177.0.0.
Note: If your ISP assigns a private WAN IP address such as 192.168.x.x or 10.x.x.x, the
Dynamic DNS service will not work because private addresses will not be routed
on the Internet.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
5-10 Advanced Configuration
v1.0, April 2008
When you first configured your router, two implicit static routes were created. A default route was
created with your ISP as the modem router, and a second static route was created to your local
network for all 192.168.0.x addresses. With this configuration, if you attempt to access a device on
the 134.177.0.0 network, your router forwards your request to the ISP. The ISP forwards your
request to the company where you are employed, and the request is likely to be denied by the
company’s firewall.
In this case you must define a static route, telling your router that 134.177.0.0 should be accessed
through the ISDN router at 192.168.0.100. The static route setup would look like Figure 5-6.
In this example:
•The Destination IP Address and IP Subnet Mask fields specify that this static route applies
to all 134.177.x.x addresses.
•The Gateway IP Address field specifies that all traffic for these addresses should be
forwarded to the ISDN router at 192.168.0.100.
• The value in the Metric field represents the number of routers between your network and the
destination. This is a direct connection, so it can be set to the minimum value of 2.
•The Private check box is selected only as a precautionary security measure in case RIP is
activated.
How to Configure Static Routes
1. Log in to the modem router at its default LAN address of http://192.168.0.1 with its default
user name of admin and default password of password, or using whatever user name,
password, and LAN address you have chosen for the modem router.
2. In the main menu, under Advanced, select Static Routes to display the Static Routes table.
Figure 5-5

Advanced Configuration 5-11
v1.0, April 2008
3. To add a static route:
a. Click Add to open the following Static Routes screen.
b. Enter a route name for this static route in the Route Name field. This name is for
identification purpose only.
c. Select Private if you want to limit access to the LAN only. The static route will not be
reported in RIP.
d. Select Active to make this route effective.
e. Enter the destination IP address of the final destination.
f. Enter the IP subnet mask for this destination. If the destination is a single host, type
255.255.255.255.
g. Enter the gateway IP address, which must be a router on the same LAN segment as the
router.
h. Enter a number between 2 and 15 as the metric value in the Metric field. This represents
the number of routers between your network and the destination. Usually, a setting of 2 or
3 works.

How to Configure Universal Plug and Play
Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers, access
the network and connect to other devices as needed. UPnP devices can automatically discover the
services from other registered UPnP devices on the network.
1. Select UPnP on the main menu to display the UPnP screen:
2. Fill in the settings on the UPnP screen:
•Turn UPnP On. UPnP can be enabled or disabled for automatic device configuration. The
default setting for UPnP is enabled. If UPnp is disabled, the modem router does not allow
any device to automatically control the resources, such as port forwarding (mapping), of
the modem router.
Figure 5-7
Figure 5-8
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
Advanced Configuration 5-13
v1.0, April 2008
•Advertisement Period. The advertisement period is how often the modem router
advertises (broadcasts) its UPnP information. This value can range from 1 to 1440
minutes. The default period is 30 minutes. Shorter durations ensure that control points
have current device status at the expense of additional network traffic. Longer durations
might compromise the freshness of the device status but can significantly reduce network
traffic.
•Advertisement Time To Live. The time to live for the advertisement is measured in hops
(steps) for each UPnP packet sent. A hop is the number of steps allowed to propagate for
each UPnP advertisement before it disappears. The number of hops can range from 1 to
255. The default value for the advertisement time to live is 4 hops, which should be fine
for most home networks. If you notice that some devices are not being updated or reached
correctly, then it might be necessary to increase this value a little.
•UPnP Portmap Table. The UPnP Portmap Table displays the IP address of each UPnP

Building Wireless Bridging and Repeating Networks
With the DG834N modem router, you can build large bridged wireless networks that form an
IEEE 802.11n wireless distribution system (WDS). Using the modem router with other access
points (APs) and wireless devices, you can connect clients by using their MAC addresses rather
than by specifying IP addresses.
Here are some examples of wireless bridged configurations:
•Point-to-point bridge. The modem router communicates with another bridge-mode wireless
station. See “How to Configure a Point-to-Point Bridge Configuration.”
•Multi-point bridge. The modem router is the “master” for a group of bridge-mode wireless
stations. Then all traffic is sent to this master, rather than to other access points. See “How to
Configure a Multi-Point Bridge.”

•Repeater with wireless client association. Sends all traffic to the remote access point. See
“How to Configure a Repeater with Wireless Client Association.”
To view or change these configurations, select Advanced Wireless Settings from the main menu:
How to Configure a Point-to-Point Bridge Configuration
In point-to-point bridge mode, the DG834N modem router communicates as an access point with
another bridge-mode wireless station. As a bridge, wireless client associations are disabled—only
wired clients can be connected. You must enter the MAC address of the other bridge-mode
wireless station in the field provided. Use wireless security to protect this communication.
The following figure shows an example of point-to-point bridge mode.
Note: The wireless bridging and repeating feature uses the default security profile to send
and receive traffic.

To set up a point-to-point bridge configuration (shown in Figure 5-10):
1. Configure the DG834N modem router (AP 1) on LAN Segment 1 in point-to-point bridge
mode.
2. Configure the other access point (AP 2) on LAN Segment 2 in point-to-point bridge mode.
The DG834N modem router must have AP 2’s MAC address in its Remote MAC Address
field, and AP 2 must have the DG834N’s MAC address in its Remote MAC Address field.
3. Configure both APs and verify that both APs are using he same SSID, channel, authentication
mode, if any, and security settings if security is in use.
4. Disable the DHCP server on AP2. AP1 will then be the DHCP server.
5. Verify connectivity across LAN Segment 1 and LAN Segment 2.
A computer on either LAN segment should be able to connect to the Internet or share files and
printers of any other PCs or servers connected to LAN Segment 1 or LAN Segment 2.

• Only one AP, the DG834N modem router in Figure 5-11, is configured in point-to-multi-
point bridge mode; all the others are in point-to-point bridge mode.
• All APs, including the DG834N modem router, must be on the same LAN. That is, all the
AP LAN IP addresses must be in the same network.
• If you are using DHCP, all access points should be set to Obtain an IP address
automatically (DHCP Client) in the IP Address Source section of the Basic IP Settings
screen.
• All APs, including the DG834N modem router, must use the same SSID, channel,
authentication mode, if any, and security settings if security is in use.
• All point-to-point APs must have the MAC address of AP 1 (the DG834N modem router
in the previous figure) in the Remote AP MAC address field.
4. Verify connectivity across the LANs.
• A computer on any LAN segment should be able to connect to the Internet or share files
and printers with any other PCs or servers connected to any of the three LAN segments.
Note: Wireless stations configured as they are in Figure 5-11 will not be able to connect
to the modem router or access points. If you require wireless stations to access any

How to Configure a Repeater with Wireless Client Association
In the repeater mode with wireless client association, the DG834N modem router sends all traffic
to a remote AP. For the repeater mode, you must enter the MAC address of the remote “parent”
access point. Alternatively, you can configure the DG834N modem router as the parent by entering
the address of a “child” access point. Note that the following restrictions apply:
•You do not have the option of disabling client associations with this DG834N modem router.
• You cannot configure a sequence of parent/child APs. You are limited to only one parent AP,
although if the DG834N modem router is the parent AP, it can connect with up to four child
APs.
The following figure shows an example of a Repeater mode configuration.
To set up a repeater with wireless client association:
1. Configure the operating mode of the devices.
• Configure AP 1 (the DG834N modem router in Figure 5-12) on with the MAC address of
AP 2 and AP 3 in the first two Remote MAC Address fields.

Go to “Restoring the Default Configuration and Password” on page 6-9.
• I want to clear the configuration and start over again.
Go to “Restoring the Default Configuration and Password” on page 6-9.
Basic Functioning
After you turn on power to the router, the following sequence of events should occur:
1. When power is first applied, verify that the Power LED is on.
2. After approximately 10 seconds, verify the following:
a. The Power LED is not red.
b. The LAN port LEDs are lit for any local ports that are connected.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
6-2 Troubleshooting
v1.0, April 2008
c. The WAN port LED is lit.
d. The Wireless LED is lit.
If a port’s LED is lit, a link has been established to the connected device. If a LAN port is
connected to a 100 Mbps device, verify that the port’s LED is green. If the port is 10 Mbps, the
LED is amber.
If any of these conditions does not occur, refer to the appropriate following section.
Power LED Is Not On
If the Power and other LEDs are off when your router is turned on:
• Make sure that the power cord is properly connected to your router and that the power supply
adapter is properly connected to a functioning power outlet.
• Check that you are using the 12 V DC power adapter supplied by NETGEAR for this product.
If the error persists, you have a hardware problem and should contact Technical Support.
Power LED Is Red
When the router is turned on, it performs a power-on self-test. If the Power LED turns red after a
few seconds or at any other time during normal operation, there is a fault within the router. The
Power LED also turns red when you press the default reset button, and blinks red 3 times when
you release that button. However, in this case, the modem router is working normally.
If the Power LED turns red to indicate a router fault, turn the power off and on to see if the router
recovers.
If the power LED is still red 1 minute after power up:
• Turn the power off and on to see if the router recovers.
• Clear the router’s configuration to factory defaults. This sets the router’s IP address to
192.168.0.1. This procedure is explained in “Using the Reset Button” on page 6-9.
If the error persists, you might have a hardware problem and should contact Technical Support.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
Troubleshooting 6-3
v1.0, April 2008
LAN or Internet Port LED Is Not On
If either the LAN LEDs or Internet LED does not light when the Ethernet connection is made,
check the following:
• Make sure that the Ethernet cable connections are secure at the router and at the hub or
workstation.
• Make sure that power is turned on to the connected hub or workstation.
• Make sure that you are using the correct cable when connecting the router’s Internet ADSL
port. Use the cable that was supplied with the modem router.
Troubleshooting the Web Configuration Interface
If you are unable to access the router’s Web Configuration Interface from a computer on your local
network, check the following:
• If you are using an Ethernet-connected computer, check the Ethernet connection between the
computer and the router as described in the previous section.
• Make sure that your computer’s IP address is on the same subnet as the router. If you are using
the recommended addressing scheme, your computer’s address should be in the range of
192.168.0.2 to 192.168.0.254. Follow the instructions in the online document that you can
access from “Preparing Your Network” in Appendix B for information about how to configure
your computer.
• If your router’s IP address was changed and you do not know the current IP address, clear the
router’s configuration to factory defaults. This sets the router’s IP address to 192.168.0.1. This
procedure is explained in “Using the Reset Button” on page 6-9.
• Make sure that your browser has Java, JavaScript, or ActiveX enabled. If you are using
Internet Explorer, click Refresh to be sure that the Java applet is loaded.
• Try quitting the browser and launching it again.
Note: If your computer’s IP address is shown as 169.254.x.x, recent versions of
Windows and MacOS will generate and assign an IP address if the computer
cannot reach a DHCP server. These auto-generated addresses are in the range
of 169.254.x.x. If your IP address is in this range, check the connection from
the computer to the router, and reboot your computer.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
6-4 Troubleshooting
v1.0, April 2008
• Make sure you are using the correct login information. The factory default login name is
admin, and the password is password. Make sure that Caps Lock is off when you enter this
information.
If the router does not save changes you have made in the Web Configuration Interface, check the
following:
• When entering configuration settings, be sure to click the Apply button before moving to
another screen or tab, or your changes are lost.
• Click the Refresh or Reload button in the Web browser. The changes might have occurred,
but the Web browser might be caching the old configuration.
Troubleshooting the ISP Connection
If your router is unable to access the Internet, you should check the ADSL connection, then the
WAN TCP/IP connection.
ADSL Link
If your router is unable to access the Internet, you should first determine whether you have an
ADSL link with the service provider. The state of this connection is indicated with the Internet
LED.
Internet LED Is Green or Blinking Green
If your Internet LED is green or blinking green, then you have a good ADSL connection. You can
be confident that the service provider has connected your line correctly and that your wiring is
correct.
Internet LED Is Blinking Amber
If your Internet LED is blinking amber, then your modem router is attempting to make an ADSL
connection with the service provider. The LED should turn green within several minutes.
If the Internet LED does not turn green, disconnect all telephones on the line. If this solves the
problem, reconnect the telephones one at a time, being sure to use a microfilter on each telephone.
If the microfilters are connected correctly, you should be able to connect all your telephones.
If disconnecting telephones does not result in a green Internet LED, there might be a problem with
your wiring. If the telephone company has tested the ADSL signal at your network interface
device (NID), then you might have poor-quality wiring in your house.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
Troubleshooting 6-5
v1.0, April 2008
Internet LED Is Off
If the Internet LED is off, disconnect all telephones on the line. If this solves the problem,
reconnect the telephones one at a time, being sure to use a microfilter on each telephone. If the
microfilters are connected correctly, you should be able to connect all your telephones.
If disconnecting telephones does not result in a green Internet LED, check for the following:
• Check that the telephone company has made the connection to your line and tested it.
• Verify that you are connected to the correct telephone line. If you have more than one phone
line, be sure that you are connected to the line with the ADSL service. It might be necessary to
use a swapper if your ADSL signal is on pins 1 and 4 or the RJ-11 jack. The modem router
uses pins 2 and 3.
Obtaining an Internet IP Address
If your modem router is unable to access the Internet, and your Internet LED is green or blinking
green, you should determine whether the modem router is able to obtain an Internet IP address
from the ISP. Unless you have been assigned a static IP address, your modem router must request
an IP address from the ISP. You can determine whether the request was successful using the
browser interface.
To check the Internet IP address from the browser interface:
1. Launch your browser, and select an external site such as www.netgear.com.
2. Access the main menu of the modem router’s configuration at http://192.168.0.1.
3. In the main menu, under Maintenance, check that an IP address is shown for the WAN port.
If 0.0.0.0 is shown, your modem router has not obtained an IP address from your ISP.
If your router is unable to obtain an IP address from the ISP, the problem might be one of the
following:
• If you have selected a login program, the service name, user name, or password might be
incorrectly set. See the following section, “Troubleshooting PPPoE or PPPoA.
• Your ISP might check for your computer’s host name.
Assign the computer host name of your ISP account to the modem router in the browser-based
Setup Wizard.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
6-6 Troubleshooting
v1.0, April 2008
• Your ISP allows only one Ethernet MAC address to connect to Internet, and might check for
your computer’s MAC address. In this case, do one of the following:
– Inform your ISP that you have bought a new network device, and ask them to use the
router’s MAC address.
– Configure your router to spoof your computer’s MAC address. This can be done in the
Basic Settings screen. See the ADSL Modem Wireless Router Setup Manual.
Troubleshooting PPPoE or PPPoA
The PPPoA or PPPoA connection can be debugged as follows:
1. Access the main menu of the router at http://192.168.0.1.
2. Under Maintenance, select Router Status.
3. Click the Connection Status button.
4. If all of the steps indicate OK, then your PPPoE or PPPoA connection is up and working.
5. If any of the steps indicates Failed, you can attempt to reconnect by clicking Connect. The
modem router will continue to attempt to connect indefinitely.
If you cannot connect after several minutes, you might be using an incorrect service name, user
name, or password. There also might be a provisioning problem with your ISP.
Troubleshooting Internet Browsing
If your modem router can obtain an IP address, but your computer is unable to load any Web pages
from the Internet:
• Your computer might not recognize any DNS server addresses.
A DNS server is a host on the Internet that translates Internet names (such as www addresses)
to numeric IP addresses. Typically your ISP provides the addresses of one or two DNS servers
for your use. If you entered a DNS address during the modem router’s configuration, reboot
your computer, and verify the DNS address as described in the online document that you can
access from “Preparing Your Network” in Appendix B. Alternatively, you can configure your
computer manually with DNS addresses, as explained in your operating system
documentation.
Note: Unless you connect manually, the modem router will not authenticate using PPPoE
or PPPoA until data is transmitted to the network.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
Troubleshooting 6-7
v1.0, April 2008
• Your computer might not have the modem router configured as its TCP/IP modem router.
If your computer obtains its information from the modem router by DHCP, reboot the
computer, and verify the modem router address as described in the online document that you
can access from “Preparing Your Network” in Appendix B.
Troubleshooting a TCP/IP Network Using the Ping Utility
Most TCP/IP terminal devices and routers contain a ping utility that sends an echo request packet
to the designated device. The device then responds with an echo reply. You can easily troubleshoot
a TCP/IP network by using the ping utility in your computer.
Testing the LAN Path to Your Router
You can ping the router from your computer to verify that the LAN path to your router is set up
correctly.
To ping the router from a PC running Windows 95 or later:
1. From the Windows toolbar, click the Start button, and select Run.
2. In the field provided, type Ping followed by the IP address of the router, as in this example:
ping 192.168.0.1
3. Click OK.
You should see a message like this one:
Pinging <IP address> with 32 bytes of data
If the path is working, you see this message:
Reply from < IP address >: bytes=32 time=NN ms TTL=xxx
If the path is not working, you see this message:
Request timed out
If the path is not functioning correctly, you could have one of the following problems:
• Wrong physical connections
– Make sure that the LAN port LED is on. If the LED is off, follow the instructions in
“LAN or Internet Port LED Is Not On” on page 6-3.
– Check that the corresponding Link LEDs are on for your network interface card and
for the hub ports (if any) that are connected to your workstation and router.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
6-8 Troubleshooting
v1.0, April 2008
• Wrong network configuration
– Verify that the Ethernet card driver software and TCP/IP software are both installed
and configured on your PC or workstation.
– Verify that the IP address for your router and your workstation are correct and that the
addresses are on the same subnet.
Testing the Path from Your Computer to a Remote Device
After verifying that the LAN path works correctly, test the path from your PC to a remote device.
In the Windows Run screen, type:
PING -n 10 IP address
where IP address is the IP address of a remote device such as your ISP’s DNS server.
If the path is functioning correctly, replies as in the previous section are displayed. If you do not
receive replies:
• Check that your PC has the IP address of your router listed as the default modem router. If the
IP configuration of your PC is assigned by DHCP, this information will not be visible in your
PC’s Network Control Panel. Verify that the IP address of the router is listed as the default
modem router as described in the online document that you can access from “Preparing Your
Network” in Appendix B.
• Check to see that the network address of your PC (the portion of the IP address specified by
the netmask) is different from the network address of the remote device.
• Check that your cable or DSL modem is connected and functioning.
• If your ISP assigned a host name to your PC, enter that host name as the account name in the
Basic Settings screen.
• Your ISP could be rejecting the Ethernet MAC addresses of all but one of your PCs. Many
broadband ISPs restrict access by allowing traffic only from the MAC address of your
broadband modem, but some ISPs additionally restrict access to the MAC address of a single
PC connected to that modem. If this is the case, you must configure your router to “clone” or
“spoof” the MAC address from the authorized PC. Refer to your ADSL Modem Wireless
Router Setup Manual.

Restoring the Default Configuration and Password
This section explains how to restore the factory default configuration settings, changing the
router’s administration password to password and the IP address to 192.168.0.1. You can erase the
current configuration and restore factory defaults in two ways:
• Use the Erase function of the Web Configuration Manager (see “Backing Up, Restoring, and
Erasing Your Settings” on page 4-1).
• Use the default reset button on the rear panel of the router. Use this method for cases when the
administration password or IP address is not known.
Using the Reset Button
To restore the factory default configuration settings when you do not know the administration
password or IP address, you must use the default reset button on the rear panel of the router.
1. Press and hold the default reset button until the Power LED turns red (about 5 seconds).
2. Release the default reset button. The LED blinks red three times and then turn green when the
router has reset to the factory default state. Wait for the router to reboot.
Problems with Date and Time
In the main menu, under Security, select Schedule to display the current date and time of day. The
modem router uses the Network Time Protocol (NTP) to obtain the current time from one of
several network time servers on the Internet. Each entry in the log is stamped with the date and
time of day. Problems with the date and time function can include:
• Date shown is January 1, 2000.
Cause. The router has not yet successfully reached a network time server. Check that your
Internet access is configured correctly. If you have just completed configuring the router, wait
at least 5 minutes, and check the date and time again.
• Time is off by one hour.
Cause. The router does not automatically sense daylight savings time. In the Schedule screen,
select the Adjust for Daylight Savings Time check box.
