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.
CAUTION:
1) To comply with FCC RF exposure compliance requirements, a separation
distance of at least 20 cm must be maintained between the antenna of this
device and all persons.
2) This transmitter must not be co-located or operating in conjunction with
any other antenna or transmitter.

— 802.11b+g modes
— 802.11g-only
— 802.11b-only
• 64-bit and 128-bit WEP encryption security.
• WEP keys can be generated manually or by passphrase.
• Wireless access can be restricted by MAC address.
• Wireless network name broadcast can be turned off so that only devices that have the network
name (SSID) can connect.
A Powerful, True Firewall
Unlike simple Internet sharing NAT routers, the DG834PN is a true firewall, using stateful packet
inspection to defend against hacker attacks. Its firewall features include:
• 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.
• Blocks unwanted traffic from the Internet to your LAN.
• Blocks access from your LAN to Internet locations or services that you specify as off-limits.
• Logs security incidents
The DG834PN will log security events such as blocked incoming traffic, port scans, attacks,
and administrator logins. You can configure the wireless ADSL modem router to email the log
to you at specified intervals. You can also configure the wireless ADSL modem router to send
immediate alert messages to your email address or email pager whenever a significant event
occurs.
Easy Installation and Management
You can install, configure, and operate the DG834PN within minutes after connecting it to the
network. The following features simplify installation and management tasks:
• Browser-based management
Browser-based configuration allows you to easily configure your wireless ADSL modem
router from almost any type of personal computer, such as Windows, Macintosh, or Linux. A
user-friendly Setup Wizard is provided and online help documentation is built into the
browser-based Web Management Interface.
Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router
2-4 Introduction
August 2005
• Smart Wizard
The wireless ADSL modem router automatically senses the type of Internet connection, asking
you only for the information required for your type of ISP account.
• Remote management
The wireless ADSL modem router allows you to log in to the Web management interface from
a remote location via the Internet. For security, you can limit remote management access to a
specified remote IP address or range of addresses, and you can choose a nonstandard port
number.
• Diagnostic functions
The wireless ADSL modem router incorporates built-in diagnostic functions such as Ping,
DNS lookup, and remote reboot. These functions allow you to test Internet connectivity and
reboot the wireless ADSL modem router. You can use these diagnostic functions directly from
the DG834PN when you are connected on the LAN or when you are connected over the
Internet via the remote management function.
• Visual monitoring
The wireless ADSL modem router’s front panel LEDs provide an easy way to monitor its
status and activity.
• Flash erasable programmable read-only memory (EPROM) for firmware upgrades.
Protocol Support
The DG834PN supports Transmission Control Protocol/Internet Protocol (TCP/IP) and Routing
Information Protocol (RIP). Appendix B, “Network and Routing Basics” provides further
information on TCP/IP.
• The Ability to Enable or Disable IP Address Sharing by NAT
The DG834PN allows several networked PCs to share an Internet account using only a single
IP address, which may be statically or dynamically assigned by your Internet service provider
(ISP). This technique, known as Network Address Translation (NAT), allows the use of an
inexpensive single-user ISP account. This feature can also be turned off completely while
using the DG834PN if you want to manage the IP address scheme yourself.
• Automatic Configuration of Attached PCs by DHCP
The DG834PN dynamically assigns network configuration information, including IP, wireless
ADSL modem router, and domain name server (DNS) addresses, to attached PCs on the LAN
using the Dynamic Host Configuration Protocol (DHCP). This feature greatly simplifies
configuration of PCs on your local network.
Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router
Introduction 2-5
August 2005
• DNS Proxy
When DHCP is enabled and no DNS addresses are specified, the wireless ADSL modem
router provides its own address as a DNS server to the attached PCs. The wireless ADSL
modem router obtains actual DNS addresses from the ISP during connection setup and
forwards DNS requests from the LAN.
• Classical IP (RFC 1577)
Some Internet service providers, in Europe for example, use Classical IP in their ADSL
services. In such cases, the wireless ADSL modem router is able to use the Classical IP
address from the ISP.
• PPP over Ethernet (PPPoE)
PPP over Ethernet is a protocol for connecting remote hosts to the Internet over an ADSL
connection by simulating a dial-up connection. This feature eliminates the need to run a login
program such as EnterNet or WinPOET on your computer.
• PPP over ATM (PPPoA)
PPP over ATM is a protocol for connecting remote hosts to the Internet over an ADSL
connection by simulating an ATM connection.
• Dynamic DNS
Dynamic DNS services allow remote users to find your network using a domain name when
your IP address is not permanently assigned. The wireless ADSL modem router contains a
client that can connect to many popular Dynamic DNS services to register your dynamic IP
address.
• Universal Plug and Play (UPnP)
UPnP is a networking architecture that provides compatibility between networking
technologies. UPnP compliant routers provide broadband users at home and small businesses
with a seamless way to participate in online games, videoconferencing and other peer-to-peer
services.
Content Filtering
With its content filtering feature, the DG834PN prevents objectionable content from reaching your
PCs. The wireless ADSL modem router allows you to control access to Internet content by
screening for keywords within Web addresses. You can configure the wireless ADSL modem
router to log and report attempts to access objectionable Internet sites.
Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router
2-6 Introduction
August 2005
Auto Sensing and Auto Uplink™ LAN Ethernet Connections
With its internal 4-port 10/100 switch, the DG834PN can connect to either a 10 Mbps standard
Ethernet network or a 100 Mbps Fast Ethernet network. The local LAN ports are autosensing and
capable of full-duplex or half-duplex operation.
The wireless ADSL modem router incorporates Auto UplinkTM technology. Each local Ethernet
port will automatically sense whether the Ethernet cable plugged into the port should have a
‘normal’ connection such as to a computer or an ‘uplink’ connection such as to a switch or hub.
That port will then configure itself to the correct configuration. This feature also eliminates the
need to worry about crossover cables, as Auto Uplink will accommodate either type of cable to
make the right connection.

Chapter 3
Connecting the Router to the Internet
This chapter describes how to set up the router on your Local Area Network (LAN) and connect to
the Internet. It describes how to configure your DG834PN 108 Mbps RangeMaxTM Wireless
ADSL Modem Router for Internet access using the Setup Wizard, or how to manually configure
your Internet connection.
What You Need Before You Begin
You need to prepare the following before you can establish an Internet connection through your
router:
1. The router connected to an ADSL line and a computer properly connected to the router as
explained below.
2. Active Internet service such as that provided by an ADSL account.
3. The Internet Service Provider (ISP) configuration information for your DSL account.
Note: If you purchased the DG834PN in a country where a microfilter is not included, you must
acquire one.
ADSL Microfilter Requirements
ADSL technology uses the same wires as your telephone service. However, ADSL adds signals to
the telephone lines which create noise in the telephone service. You must use ADSL microfilters to
filter out these signals before they reach your telephone.

Each device such as a telephone, fax machine, answering machine, or caller ID display will require
an ADSL microfilter.
Note: Do not connect the DG834PN to the ADSL line through a microfilter unless the microfilter
is a combination microfilter/splitter specifically designed for this purpose. Doing so will prevent
the built-in ADSL modem in the DG834PN from establishing a connection to the Internet. If you
have any doubts about this, connect the DG834PN directly to the ADSL line.
ADSL Microfilter with Built-In Splitter
Figure 3-2: ADSL microfilter with built-in splitter
Use an ADSL microfilter with built-in splitter when there is a single wall outlet which must
provide connectivity for both the DG834PN and telephone equipment.
Ethernet Cabling Requirements
The DG834PN RangeMax Wireless ADSL Modem Router connects to your Ethernet LAN via
twisted-pair cables. If the computer will connect to your network at 100 Mbps, you must use a
Category 5 (CAT5) cable such as the one provided with your wireless ADSL modem router.
Computer Hardware Requirements
To use the DG834PN RangeMax Wireless ADSL Modem Router on your network, each computer
must have an installed Ethernet adapter and an Ethernet cable, or a 802.11g wireless adapter.
LAN Configuration Requirements
For the initial connection to the Internet and configuration of your router, you need to connect a
computer to the router which is set to automatically get its TCP/IP configuration from the router
via DHCP.
Note: Please refer to Appendix C, “Preparing Your Network” for assistance with DHCP
configuration.

Internet Configuration Requirements
Depending on how your ISP set up your Internet account, you need one or more of these
configuration parameters to connect your router to the Internet:
• Virtual Path Identifier (VPI)/Virtual Channel Indentifier (VCI) parameters
• Multiplexing Method
• Host and Domain Names
• ISP Login Name and Password
• ISP Domain Name Server (DNS) Addresses
• Fixed or Static IP Address
Where Do I Get the Internet Configuration Parameters?
There are several ways you can gather the required Internet connection information.
• Your ISP should have provided you with all the information needed to connect to the Internet.
If you cannot locate this information, you can ask your ISP to provide it or you can try one of
the options below.
• If you have a computer already connected using the active Internet access account, you can
gather the configuration information from that computer.
• For Windows 95/98/ME, open the Network control panel, select the TCP/IP entry for the
Ethernet adapter, and click Properties.
• For Windows 2000/XP, open the Local Area Network Connection, select the TCP/IP entry
for the Ethernet adapter, and click Properties.
• For Macintosh computers, open the TCP/IP or Network control panel.
• You can also refer to the DG834PN Resource CD for the NETGEAR Router ISP Guide which
provides Internet connection information for many ISPs.

Set up the Router
1. CONNECT THE DG834PN TO THE ADSL LINE
ADSL signals degrade phone sound quality. Microfilters block such problems and are required
for each phone or fax. There are two types: one-line microfilters; and two-line microfilters,
which include a built-in splitter. Sharing a phone outlet with two devices requires a splitter.
The procedure below illustrates using a two-line combo microfilter/splitter.
You can accomplish the same result using a one-line microfilter with a separate phone line
splitter.
a. Insert the filter into the phone outlet and connect the phone to the phone connector (A).
b. Turn off your computer.

6. Usually the default ADSL Settings work fine for most ISPs and you can skip this step. If you
have any problems with your connection, check the ADSL Settings. See “ADSL Settings” on
page 3-14 for more details.
Internet Connection Requires Login and Uses PPPoE
1. If your Internet connection does require login, select Yes and fill in the settings according to
the instructions below.
Note: You will no longer need to launch the ISP’s login program on your computer in order to
access the Internet. When you start an Internet application, your wireless ADSL modem router
automatically logs you in.
2. Choose PPPoE for the encapsulation method.
3. Enter the login name (frequently the email address your ISP provided), password, and service
name (if required).
4. If you want to change the login timeout, enter a new value in minutes. This determines how
long the wireless ADSL modem router keeps the Internet connection active after there is no
Internet activity from the LAN. Entering an Idle Timeout value of zero means never log out.
5. When a connection uses PPPoE, the IP address is normally assigned automatically. However,
the DG834PN allows this address to be set manually.
• Select “Get Automatically from ISP” if your ISP assigns your IP address.

Your ISP will automatically assign these addresses.
• Select “Use Static IP Address” if your ISP has assigned you a permanent, fixed (static) IP
address. Enter the IP address that your ISP assigned. Also enter the IP Subnet Mask and
the Gateway IP Address. The gateway is the ISP’s wireless ADSL modem router to which
your wireless ADSL modem router will connect.
• Select “IP Over ATM (IPoA)” if your ISP uses Classical IP Addresses (RFC1577). Enter
the IP address, IP Subnet Mask, and Gateway IP Addresses that your ISP assigned.
4. Domain Name Server (DNS) Address:
• Select “Get Dynamically from ISP” if your ISP uses DHCP to assign your IP address.
Your ISP will automatically assign this address.
• If you know that your ISP does not automatically transmit DNS addresses to the wireless
ADSL modem router during login, select “Use these DNS servers” and enter the IP
address of your ISP’s Primary DNS Server. If a Secondary DNS Server address is
available, enter it also.
A DNS server is a host on the Internet that translates Internet names (such as
www.netgear.com) to numeric IP addresses. Typically your ISP transfers the IP address of one
or two DNS servers to your wireless ADSL modem router during login. If the ISP does not
transfer an address, you must obtain it from the ISP and enter it manually here.

you will be manually administering the IP address space on the LAN side of the router
6. Wireless ADSL Modem Router MAC Address:
This section determines the Ethernet MAC address that will be used by the wireless ADSL
modem router on the Internet port. Some ISPs will register the Ethernet MAC address of the
network interface card in your computer when your account is first opened. They will then
only accept traffic from the MAC address of that computer. This feature allows your wireless
ADSL modem router to masquerade as that computer by “cloning” its MAC address.
To change the MAC address, select “Use this Computer’s MAC address”. The wireless ADSL
modem router will then capture and use the MAC address of the computer that you are now
using. You must be using the one computer that is allowed by the ISP. Alternatively, select
“Use this MAC address” and enter it.
7. Click Apply to save your settings.
8. Click the Test button to test your Internet connection.
If the NETGEAR Web site does not appear within one minute, refer to Chapter 8,
“Troubleshooting”.
ADSL Settings
The default settings of your DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router
will work fine for most ISPs. However, some ISPs use a specific Multiplexing Method and Virtual
Circuit Number for the Virtual Path Identifier (VPI) and Virtual Channel Identifier (VCI).
Note: The correct country must be selected from the Setup Wizard’s first page for the default
ADSL Settings to work.
If your ISP provided you with a specific Multiplexing Method or VPI/VCI number, then fill in the
following:
1. Select the ADSL Settings link from the main menu.

Chapter 4
Wireless Configuration
This chapter describes how to configure the wireless features of your DG834PN 108 Mbps
RangeMaxTM Wireless ADSL 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 ADSL modem router in order to maximize the
network speed. For further information, refer to Appendix D, “Wireless Networking Basics”.
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)
• Away from sources of interference, such as computers, microwaves, and cordless phones
• With the Antenna tight and in the upright position
• Away from large metal surfaces
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”.

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
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 DG834PN RangeMax Wireless ADSL Modem Router provides
highly effective security features which are covered in detail in this chapter. Deploy the security
features appropriate to your needs.
Figure 4-1: DG834PN wireless data security options
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 DG834PN. 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.
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.
1) Open System: Easy but no security
2) MAC Access List: No data security
3) WEP: Security but some performance impact
4) WPA-PSK

•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.
•WPA-PSK. Wi-Fi Protected Access (WPA) data encryption provides data security. The very
strong authentication along with dynamic per frame re-keying of WPA make it virtually
impossible to compromise. Because this is a new standard, wireless device driver and software
availability may be limited.
Understanding Wireless Settings
To configure the Wireless interface of your wireless ADSL modem router, click the Wireless link
in the main menu of the browser interface. The following Wireless Settings menu will appear after
WEP (Wired Equivalent Privacy) under Security Options is subsequently selected:

WPA 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. For a full
explanation of WPA, see “WPA Wireless Security” on page D-8.
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.
WPA-802.1x User authentication is implemented using 802.1x and RADIUS servers. For a full
explanation of WPA, see “WPA Wireless Security” on page D-8.
Fill in the following:
• Radius Server Name/IP Address
This field is required. Enter the name or IP address of the Radius Server on your LAN.
• Radius Port

Once your computers have basic wireless connectivity to the firewall, you can configure the
advanced wireless security functions of the firewall.
How to Restricting Wireless Access to Your Network
By default, any wireless PC that is configured with the correct SSID will be allowed access to your
wireless network. For increased security, the DG834PN 108 Mbps RangeMaxTM Wireless ADSL
Modem Router provides several ways to restrict wireless access to your network:
• 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 below.
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.

Figure 4-4: Wireless Access Point settings
Restricting Access to Your Network by Turning Off Wireless Connectivity
You can completely turn off the wireless portion of the DG834PN. For example, if your notebook
computer is used 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 via Ethernet cables will still be able to use the router.
Restricting Wireless Access Based on the Wireless Network Name (SSID)
The DG834PN 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 will not ‘see’ your DG834PN. You must configure your wireless devices to match
the wireless network name (SSID) you configure in the DG834PN RangeMax Wireless ADSL
Modem Router.
Note: The SSID of any wireless access adapters must match the SSID you configure in the
DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router. If they do not match, you will
not get a wireless connection to the DG834PN.
Restricting Wireless Access Based on the Wireless Station Access List
This list determines which wireless hardware devices will be allowed to connect to the firewall.
To restrict access based on MAC addresses, follow these steps:
1. Log in to the DG834PN 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. From the Wireless Settings menu, Wireless Station Access List section, click the Setup Access

Choosing WEP Authentication and Security Encryption Methods
Figure 4-6. Security Encryption section
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.
Authentication Type Selection
The DG834PN lets you select the following wireless authentication schemes.
Note: If you are configuring the wireless ADSL 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

Protecting Your Network
This chapter describes how to use the basic firewall features of the DG834PN 108 Mbps
RangeMaxTM Wireless ADSL Modem Router to protect your network.
Protecting Access to Your DG834PN 108 Mbps RangeMaxTM
Wireless ADSL Modem Router
For security reasons, the wireless ADSL 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 ADSL modem router User Name and
password for the wireless ADSL modem router Password. You can use procedures below to
change the wireless ADSL 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 ADSL 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

Blocking Keywords, Sites, and Services
The wireless ADSL modem router provides a variety of options for blocking Internet based
content and communications services. With its content filtering feature, the DG834PN RangeMax
Wireless ADSL Modem Router prevents objectionable content from reaching your PCs. The
wireless ADSL 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 ADSL modem router to perform
these functions.
How to Block Keywords and Sites
The DG834PN RangeMax Wireless ADSL 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 ADSL 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 ADSL modem router.

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 DG834PN 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 5-11 for more details.
To access the rules configuration of the DG834PN, click the Firewall Rules link on the main menu,
then click Add for either an Outbound or Inbound Service.

• 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 script prompt, enter the number of the desired new
position and click OK.
Inbound Rules (Port Forwarding)
Because the DG834PN 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 ADSL 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.
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 5-5:
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.

These settings determine which packets are covered by the rule, based on their source
(WAN) IP address. Select the desired option:
• Any — all IP addresses are covered by this rule.
• Address range — if this option is selected, you must enter 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 which matches the parameters and action will be logged.
• Not match — traffic of this type which does not match the parameters and action will
be logged.
Inbound Rule Example: Allowing Videoconferencing
If you want to allow incoming videoconferencing 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 5-6, 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.

Protecting Your Network 5-9
August 2005
Figure 5-6: Rule example: Videoconference from Restricted Addresses
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 5-6 above). Attempts by local computers to access the
server using the external WAN IP address will fail.
Outbound Rules (Service Blocking)
The DG834PN 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 ADSL modem router log any attempt to use Instant Messenger during that blocked
period.

Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router
5-12 Protecting Your Network
August 2005
Figure 5-8: Rules table with examples
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

Chapter 7
Advanced Configuration
This chapter describes how to configure the advanced features of your DG834PN 108 Mbps
RangeMaxTM Wireless ADSL Modem Router.
Configuring Advanced Security
The DG834PN 108 Mbps RangeMaxTM Wireless ADSL 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 ADSL 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.
Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router
7-2 Advanced Configuration
August 2005
Incoming traffic from the Internet is normally discarded by the wireless ADSL 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 ADSL 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 ADSL modem router.
2. From the Main Menu, under Advanced, click the WAN Setup link to view the page shown in
Figure 7-1:
Figure 7-1: WAN Setup Page
3. Select the Default DMZ Server check box.
4. Type the IP address for that server.
5. Click Apply to save your changes.
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.
Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router
Advanced Configuration 7-3
August 2005
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 ADSL 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 ADSL 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 ADSL modem router is shipped preconfigured to use private IP addresses on the
LAN side, and to act as a DHCP server. The wireless ADSL modem router’s default LAN IP
configuration is:

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 7-2: LAN IP Setup Menu
The LAN TCP/IP Setup parameters are:
• IP Address
This is the LAN IP address of the wireless ADSL modem router.
• IP Subnet Mask
This is the LAN Subnet Mask of the wireless ADSL 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 ADSL modem router.
• RIP Direction
RIP (Router Information Protocol) allows a wireless ADSL modem router to exchange routing
information with other routers. The RIP Direction selection controls how the Wireless ADSL
Modem Router sends and receives RIP packets. Both is the default.
— When set to Both or Out Only, the wireless ADSL modem router will broadcast its routing
table periodically.
— When set to Both or In Only, it will incorporate the RIP information that it receives.
Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router
Advanced Configuration 7-5
August 2005
— 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
ADSL 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.
— 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.
DHCP
By default, the wireless ADSL 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 ADSL 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 “IP
Configuration by DHCP”on page B-9 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.
Note: If you change the LAN IP address of the wireless ADSL 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.
Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router
7-6 Advanced Configuration
August 2005
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
• 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.

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 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.
Figure 7-4: Dynamic DNS menu

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.
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.
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.
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.
Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router
7-10 Advanced Configuration
August 2005
• 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 ADSL 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 would look like Figure 7-6.
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 Wireless ADSL Modem Router IP Address fields specifies that all traffic for these
addresses should be forwarded to the ISDN router at 192.168.0.100.
• A Metric value of 1 will work since the ISDN router is on the LAN.
This represents the number of routers between your network and the destination. This is a
direct connection so it is set to 1.
• 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 7-5.

d. Select Active to make this route effective.
e. Type the Destination IP Address of the final destination.
f. Type the IP Subnet Mask for this destination.
If the destination is a single host, type 255.255.255.255.
g. Type the Gateway IP Address, which must be a router on the same LAN segment as the
router.
h. Type a number between 1 and 15 as the Metric value.
This represents the number of routers between your network and the destination. Usually,
a setting of 2 or 3 works, but if this is a direct connection, set it to 1.

• I can’t remember the router’s configuration password.
• I want to clear the configuration and start over again.
Go to “Restoring the Default Configuration and Password” on page 8-9.
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 (see “The Router’s Front Panel”
on page 2-6 for an illustration and explanation of the LEDs).
2. Verify that the Test LED lights within a few seconds, indicating that the self-test procedure is
running.
3. After approximately 10 seconds, verify that:
a. The Test LED is not lit.
b. The LAN port LEDs are lit for any local ports that are connected.
c. The WAN port LED is lit.
Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router
8-2 Troubleshooting
August 2005
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.
Test LED Never Turns On or Test LED Stays On
When the router is turned on, the Test LED turns on for about 10 seconds and then turns off. If the
Test LED does not turn on, or if it stays on, there is a fault within the router.
If you experience problems with the Test LED:
• Cycle the power to see if the router recovers and the LED blinks for the correct amount of
time.
If all LEDs including the Test LED are still on 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 8-9.
If the error persists, you might have a hardware problem and should contact technical support.
LAN or WAN Port LEDs Not On
If either the LAN LEDs or WAN 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.
Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router
Troubleshooting 8-3
August 2005
• 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 WAN ADSL port, use the cable that was supplied with the
DG834PN.
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. Refer to “Verifying TCP/IP Properties” on page C-6 or
“Verifying TCP/IP Properties for Macintosh Computers” on page C-17 to find your
computer’s IP address. Follow the instructions in Appendix C 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 8-9.
• 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 WAN LED.
WAN LED Green or Blinking Green
If your WAN 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.
WAN LED Blinking Yellow
If your WAN LED is blinking yellow, then your wireless ADSL modem router is attempting to
make an ADSL connection with the service provider. The LED should turn green within several
minutes.
If the WAN 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 WAN 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.
WAN LED Off
If the WAN 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.
Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router
Troubleshooting 8-5
August 2005
If disconnecting telephones does not result in a green WAN 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 you ADSL signal is on pins 1 and 4 or the RJ-11 jack. The DG834PN
RangeMax Wireless ADSL Modem Router uses pins 2 and 3.
Obtaining a WAN IP Address
If your wireless ADSL modem router is unable to access the internet, and your WAN LED is green
or blinking green, you should determine whether the wireless ADSL modem router is able to
obtain a WAN IP address from the ISP. Unless you have been assigned a static IP address, your
wireless ADSL 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 WAN 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 ADSL 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 ADSL 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:
• Your ISP may require a Multiplexing Method or Virtual Path Identifier/Virtual Channel
Identifier parameter.
Verify with your ISP the Multiplexing Method and parameter value, and update the router’s
ADSL Settings accordingly.
• Your ISP may require a login program.
Ask your ISP whether they require PPP over Ethernet (PPPoE) or PPP over ATM (PPPOA)
login.
• 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.
Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router
8-6 Troubleshooting
August 2005
• Your ISP may check for your computer's host name.
Assign the computer Host Name of your ISP account to the wireless ADSL 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:
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 “Manually Configuring Your Internet Connection” on page 3-10.
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 ADSL 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.
Troubleshooting Internet Browsing
If your wireless ADSL 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.
Note: Unless you connect manually, the wireless ADSL modem router will not
authenticate using PPPoE or PPPoA until data is transmitted to the network.
Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router
Troubleshooting 8-7
August 2005
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 ADSL modem router’s
configuration, reboot your computer and verify the DNS address as described in “Verifying
TCP/IP Properties” on page C-6. Alternatively, you can configure your computer manually
with DNS addresses, as explained in your operating system documentation.
• Your computer may not have the wireless ADSL modem router configured as its TCP/IP
wireless ADSL modem router.
If your computer obtains its information from the wireless ADSL modem router by DHCP,
reboot the computer and verify the wireless ADSL modem router address as described in
“Verifying TCP/IP Properties” on page C-6.
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 <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
Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router
8-8 Troubleshooting
August 2005
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 WAN Port LEDs Not On” on page 8-2.
— 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 <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 wireless ADSL
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 ADSL modem router as described in “Verifying
TCP/IP Properties” on page C-6.
— 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 “Manually
Configuring Your Internet Connection” on page 3-10.
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 6-1).
• 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
DG834PN RangeMax Wireless ADSL 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.
