Federal Communications Commission (FCC) Compliance Notice: Radio Frequency Notice
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 or more 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.
Federal Communications Commission (FCC) Radiation Exposure Statement

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

Introduction
v1.0, May 2005
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 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.
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

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 security
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.

How to Configure WPA-PSK/WPA2-PSK Security
A high performance client like the NETGEAR WN511B must connect using WPA2-PSK in order
to achieve maximum performance. Wireless clients that connect to this router using WPA-PSK
will run at no more than 802.11g speed. This option allows wireless clients to use either encryption
method.
Note: Not all wireless adapters support WPA. 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.
To configure WPA-PSK + WPA2-PSK, follow these steps:
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.

Figure 2-5
Restricting wireless access prevents intruders from connecting to your network. However, the
wireless data transmissions are still vulnerable to snooping. Using the WEP data encryption
settings described below 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.

Protecting Your Network
This chapter describes how to use the basic firewall features of the DG834N RangeMaxTM NEXT
Wireless ADSL2+ Modem Router to protect your network.
Protecting Access to Your Wireless Modem Router
For security reasons, the wireless modem router has its own user name and password. Also, after a
period of inactivity for a set length of time, the administrator login will automatically disconnect.
When prompted, enter admin for the wireless modem router user name and password for the
wireless modem router password. You can use procedures below to change the wireless modem
router's password and the amount of time for the administrator’s login timeout.
Note: The user name and password are not the same as any user name or password your
may use to log in to your Internet connection.
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 and lower case letters, numbers, and symbols. Your password can be up to 30 characters.
How to Change the Built-In Password
1. Log in to the wireless modem router at its default LAN address of http://192.168.0.1 with its
default User Name of admin, default password of password, or using whatever Password and
LAN address you have chosen for the wireless modem router.

Blocking Keywords, Sites, and Services
The wireless 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 wireless
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 section below explains how to configure your wireless modem router to perform these
functions.
How to Block Keywords and Sites
The RangeMax NEXT Wireless ADSL2+ 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 wireless modem router at its default LAN address of http://192.168.0.1 with its

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 are used to 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 DG834N 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 will take
effect first. See “Order of Precedence for Rules” on page 3-11 for more details.

•
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 script prompt, enter the number of the desired new position
and click OK.
Inbound Rules (Port Forwarding)
Because the wireless 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 wireless
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.
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 may
periodically check for servers and may 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.

Remember that allowing inbound services opens holes in your firewall. Only enable 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 Figure 3-5:

– Match: Traffic of this type that matches the parameters and action will be logged.
– Not match: Traffic of this type that does not match the parameters and action will be

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 Figure 3-6, 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 parameters.
Figure 3-6
Considerations for Inbound Rules
•
If your external IP address is assigned dynamically by your ISP, the IP address may change
periodically as the DHCP lease expires. Consider using the Dynamic DNS feature in the
Advanced menu so that external users can always find your network.
•
If the IP address of the local server computer is assigned by DHCP, it may change when the
computer is rebooted. To avoid this, use the Reserved IP address feature in the LAN IP menu
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 Figure 3-6 above). Attempts by local computers to access the
server using the external WAN IP address will fail.
Outbound Rules (Service Blocking)
The wireless 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
• 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 have created in the Schedule menu. You can also have the
wireless modem router log any attempt to use Instant Messenger during that blocked period.

Order of Precedence for Rules
As you define new rules, they are added to the tables in the Rules menu, as shown in Figure 3-8:
Figure 3-8
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 may 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.
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.

Advanced Configuration
This chapter describes how to configure the advanced features of your DG834N RangeMaxTM
NEXT Wireless ADSL2+ Modem Router.
Configuring Advanced Security
The DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router provides a variety of
advanced features, such as:
•
Setting up a Demilitarized Zone (DMZ) Server
•
Connecting Automatically, as Required
•
Disabling Port Scan and DOS Protection
•
Responding to a Ping on the Internet WAN Port
•
MTU Size
•
Flexibility on configuring your LAN TCP/IP settings
•
Using the Router as a DHCP Server
•
Configuring Dynamic DNS
•
Configuring Static Routes
These features are discussed below.
Setting Up A Default DMZ Server
The Default DMZ Server feature is helpful when using some online games and videoconferencing
applications that are incompatible with NAT. The wireless modem router is programmed to
recognize some of these applications and to work properly with them, but there are other
applications that may not function well. In some cases, one local computer can run the application
properly if that computer’s IP address is entered as the Default DMZ Server.
Advanced Configuration
5-1
v1.0, May 2005
DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual
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.
Incoming traffic from the Internet is normally discarded by the wireless modem router unless the
traffic is a response to one of your local computers or a service that you have configured in the
Ports menu. 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, follow these steps:
1. Log in to the wireless modem router at its default LAN address of http://192.168.0.1 with its
default User Name of admin, default password of password, or using whatever Password and
LAN address you have chosen for the wireless modem router.
2. From the Main Menu, under Advanced, click the WAN Setup link to view the page shown in
Figure 5-1:
Figure 5-1
3. Select the Default DMZ Server check box.
4. Type the IP address for that server.
5. Click Apply to save your changes.

Advanced Configuration
v1.0, May 2005
DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual
Connect Automatically, as Required
Normally, this option should be enabled, so that an Internet connection will be made automatically,
whenever Internet-bound traffic is detected. If this causes high connection costs, you can disable
this setting.
If disabled, you must connect manually, using the sub-screen accessed from the "Connection
Status" button on the Status screen.
If you have an "Always on" connection, this setting has no effect.
Disable Port Scan and DOS Protection
The Firewall protects your LAN against Port Scans and Denial of Service (DOS) attacks. This
should be disabled only in special circumstances.
Respond to Ping on Internet WAN Port
If you want the wireless modem router to respond to a 'ping' from the Internet, select the ‘Respond
to Ping on Internet WAN Port’ check box. This should only be used as a diagnostic tool, since it
allows your wireless modem router to be discovered. Do not select this box unless you have a
specific reason to do so.
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 may 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.
Configuring LAN IP Settings
The LAN IP Setup menu allows configuration of LAN IP services such as DHCP and RIP. These
features can be found under the Advanced heading in the Main Menu of the browser interface.
The wireless modem router is shipped preconfigured to use private IP addresses on the LAN side,
and to act as a DHCP server. The wireless modem router’s default LAN IP configuration is:
• LAN IP addresses—192.168.0.1
• Subnet mask—255.255.255.0
Advanced Configuration
5-3
v1.0, May 2005
DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual
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 in this menu.
Figure 5-2
The LAN TCP/IP Setup parameters are:
•
IP Address: This is the LAN IP address of the wireless modem router.
•
IP Subnet Mask: This is the LAN Subnet Mask of the wireless 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 wireless modem router.
•
RIP Direction: RIP (Router Information Protocol) allows a wireless modem router to
exchange routing information with other routers. The RIP Direction selection controls how the
Wireless Modem Router sends and receives RIP packets. Both is the default.
– When set to Both or Out Only, the wireless modem router will broadcast its routing table
periodically.
– When set to Both or In Only, it will incorporate the RIP information that it receives.
– When set to None, it will not send any RIP packets and will ignore any RIP packets
received.
•
RIP Version: This controls the format and the broadcasting method of the RIP packets that the
wireless modem router sends. It recognizes both formats when receiving. By default, this is set
for RIP-1.
–
RIP-1 is universally supported. RIP-1 is probably adequate for most networks, unless you
have an unusual network setup.
5-4
Advanced Configuration
v1.0, May 2005
DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual
–
RIP-2 carries more information. Both RIP-2B and RIP-2M send the routing data in RIP-2
format.
• RIP-2B uses subnet broadcasting.
• RIP-2M uses multicasting.
Note: If you change the LAN IP address of the wireless 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.
DHCP
By default, the wireless modem router will function as a DHCP (Dynamic Host Configuration
Protocol) server, allowing it to assign IP, DNS server, and default gateway addresses to all
computers connected to the wireless modem router's LAN. The assigned default gateway address
is the LAN address of the router. IP addresses will be assigned to the attached PCs from a pool of
addresses specified in this menu. 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
“Internet Networking and TCP/IP Addressing:” in Appendix B for an explanation of DHCP and
information about how to assign IP addresses for your network.
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 may want to save part of the range for devices with fixed addresses.
The router will deliver the following parameters 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 menu;
otherwise, the router’s LAN IP address
Advanced Configuration
5-5
v1.0, May 2005
DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual
•
Secondary DNS Server, if you entered a Secondary DNS address in the Basic Settings menu
•
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.
Reserved IP addresses
When you specify a reserved IP address for a computer on the LAN, that computer will always
receive 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. Click the Add button.
2. In the IP Address box, 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.
3. Type the MAC Address of the computer or server.
Tip: If the computer is already present on your network, you can copy its MAC
address from the Attached Devices menu and paste it here.
4. Click Apply to enter the reserved address into the table.
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.
To edit or delete a reserved address entry:
1. Click the button next to the reserved address you want to edit or delete.
2. Click Edit or Delete.

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.
Advanced Configuration
5-7
v1.0, May 2005
DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual
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 will automatically contact your dynamic DNS service provider, log in to your
account, and register your new IP address.
How to Configure Dynamic DNS
1. Log in to the router at its default LAN address of http://192.168.0.1 with its default User Name
of admin, default password of password, or using whatever User Name, Password and LAN
address you have chosen for the router.
2. From the Main Menu of the browser interface, under Advanced, select Dynamic DNS to
display the page below.

3. Access the Web site of one of the dynamic DNS service providers whose names appear in the
‘Service Provider’ box, 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 may 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.

v1.0, May 2005
DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual
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
will cause *.yourhost.dyndns.org to be aliased to the same IP address as yourhost.dyndns.org
10. Click Apply to save your configuration.
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
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 is 134.177.0.0.
When you first configured your router, two implicit static routes were created. A default route was
created with your ISP as the wireless 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 will forward your request to the ISP. The ISP
forwards your request to the company where you are employed, and the request will likely 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.
Advanced Configuration
5-9
v1.0, May 2005
DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual
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 Wireless Modem Router IP Address fields specifies that all traffic for these addresses
should be forwarded to the ISDN router at 192.168.0.100.
•
The metric value 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.
•
Private is selected only as a precautionary security measure in case RIP is activated.
How to Configure Static Routes
1. Log in to the router at its default LAN address of http://192.168.0.1 with its default User Name
of admin, default password of password, or using whatever User Name, Password and LAN
address you have chosen for the router.
2. From the Main Menu of the browser interface, under Advanced, click Static Routes to view
the Static Routes menu, shown in Figure 5-5.

c. The WAN port LED is lit.
d. The Wireless LED is lit
Troubleshooting
6-1
v1.0, May 2005
DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual
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 will be amber.
If any of these conditions does not occur, refer to the appropriate following section.
Power LED 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 depress the factory default reset push button, and blinks red 3
times when that button is released. However, in this case, the wireless modem router is working
normally.
If the power LED turns red to indicate a router fault:
•
Cycle the power to see if the router recovers.
If the power LED is still red one minute after power up:
•
Cycle the power to see if the router recovers.
•
Clear the router’s configuration to factory defaults. This will set 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.
LAN or Internet Port LEDs Not On
If either the LAN LEDs or Internet LED do 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.
6-2
Troubleshooting
v1.0, May 2005
DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual
•
Make sure that power is turned on to the connected hub or workstation.
•
Be sure you are using the correct cable:
— When connecting the router’s Internet ADSL port, use the cable that was supplied with the
DG834N.
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 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 “Preparing a Computer for Network
Access:” in Appendix B to configure your computer.
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.
•
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 will set 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 your browser has Java, JavaScript, or ActiveX enabled. If you are using Internet
Explorer, click Refresh to be sure the Java applet is loaded.
•
Try quitting the browser and launching it again.
•
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 entering 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 menu or tab, or your changes are lost.
•
Click the Refresh or Reload button in the Web browser. The changes may have occurred, but
the Web browser may 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 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 Blinking Amber
If your Internet LED is blinking amber, then your wireless 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 careful 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 may be a problem with
your wiring. If the telephone company has tested the ADSL signal at your Network Interface
Device (NID), then you may have poor quality wiring in your house.
6-4
Troubleshooting
v1.0, May 2005
DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual
Internet LED 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 careful 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 the problem may be one of 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 may be necessary to
use a swapper if your ADSL signal is on pins 1 and 4 or the RJ-11 jack. The RangeMax NEXT
Wireless ADSL2+ Modem Router uses pins 2 and 3.
Obtaining an Internet IP Address
If your wireless modem router is unable to access the internet, and your Internet LED is green or
blinking green, you should determine whether the wireless modem router is able to obtain an
Internet IP address from the ISP. Unless you have been assigned a static IP address, your wireless
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 wireless modem router’s configuration at http://192.168.0.1.
3. Under the Maintenance heading check that an IP address is shown for the WAN Port.
If 0.0.0.0 is shown, your wireless 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 may be one of the
following:
•
If you have selected a login program, you may have incorrectly set the Service Name, User
Name and Password. See “Troubleshooting PPPoE or PPPoA”, below.
•
Your ISP may check for your computer's host name.
Assign the computer Host Name of your ISP account to the wireless modem router in the
browser-based Setup Wizard.
•
Your ISP only allows one Ethernet MAC address to connect to Internet, and may check for
your computer’s MAC address. In this case:
Troubleshooting
6-5
v1.0, May 2005
DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual
Inform your ISP that you have bought a new network device, and ask them to use the router’s
MAC address.
OR
Configure your router to spoof your computer’s MAC address. This can be done in the Basic
Settings menu. Refer to 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 the Maintenance heading, select the Router Status link.
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
wireless modem router will continue to attempt to connect indefinitely.
If you cannot connect after several minutes, you may be using an incorrect Service Name, User
Name or Password. There also may be a provisioning problem with your ISP.
Note: Unless you connect manually, the wireless modem router will not authenticate
using PPPoE or PPPoA until data is transmitted to the network.
Troubleshooting Internet Browsing
If your wireless modem router can obtain an IP address but your computer is unable to load any
Web pages from the Internet:
•
Your computer may 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 will provide the addresses of one or two DNS
servers for your use. If you entered a DNS address during the wireless modem router’s
configuration, reboot your computer and verify the DNS address as described in “Preparing a
Computer for Network Access:” in Appendix B. Alternatively, you can configure your
computer manually with DNS addresses, as explained in your operating system
documentation.

•
Your computer may not have the wireless modem router configured as its TCP/IP wireless
modem router.
If your computer obtains its information from the wireless modem router by DHCP, reboot the
computer and verify the wireless modem router address as described in “Preparing a Computer
for Network Access:” 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. Troubleshooting a TCP/IP
network is made very easy 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  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 the LAN port LED is on. If the LED is off, follow the instructions in “LAN
or Internet Port LEDs Not On” on page 6-2.
–
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.

•
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.
From the Windows run menu, type:
PING -n 10 
where  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 wireless 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 wireless modem router as described in “Preparing a Computer for Network
Access:” 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 menu.
•
Your ISP could be rejecting the Ethernet MAC addresses of all but one of your PCs. Many
broadband ISPs restrict access by only allowing traffic 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, or
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 without knowing 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 Test LED turns on (about 10 seconds).
2. Release the Default Reset button and wait for the router to reboot.
Problems with Date and Time
The E-mail menu in the Content Filtering section displays the current date and time of day. The
RangeMax NEXT Wireless ADSL2+ 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 settings are configured correctly. If you have just completed configuring the
router, wait at least five 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 E-mail menu,
check or uncheck the box marked “Adjust for Daylight Savings Time”.
