(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. 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.

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. Introduction 2-3 August 2005 Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router 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 routers 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. 2-4 Introduction August 2005 Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router 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. Introduction 2-5 August 2005 Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router 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. Whats in the Box?

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. ADSL Microfilter Phone Figure 3-1: ADSL microfilter Connecting the Router to the Internet 3-1 August 2005 Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router 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.

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. Note: Failure to follow these guidelines can result in significant performance degradation or inability to wirelessly connect to the router. For complete range/
performance specifications, please see Appendix A, Technical Specifications. For best results, place your firewall:
Near the center of the area in which your computers will operate In an elevated location such as a high shelf where the wirelessly connected computers have line-of-sight access (even if through walls) Away from sources of interference, such as computers, microwaves, and cordless phones With the Antenna tight and in the upright position Away from large metal surfaces Wireless Configuration 4-1 August 2005 Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router 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 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.

It should not be necessary to change the wireless channel unless you notice interference problems with another nearby wireless router or access point. Select a channel that is not being used by any other wireless networks within several hundred feet of your firewall. For more information on the wireless channel frequencies please refer to Wireless Channels on page D-7. 6. For initial configuration and test, leave the Wireless Card Access List set to allow everyone access by making sure that Turn Access Control On is not selected in the Wireless Station Access List. In addition, leave the Encryption Strength set to Disabled. 7. Click Apply to save your changes. Note: If you are configuring the firewall from a wireless computer and you change the firewalls 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 firewalls new settings. 8. Configure and test your computers for wireless connectivity. Program the wireless adapter of your computers to have the same SSID and channel that you configured in the router. Check that they have a wireless link and are able to obtain an IP address by DHCP from the firewall. 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:
Restrict access based on the Wireless Network Name (SSID) Restrict access based on the Wireless Card Access List Turn off wireless connectivity completely These options are discussed below. 4-8 Wireless Configuration August 2005 Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router 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 List button to display the list, shown below:

If the wireless station is currently connected to the network, you can select it from the Available Wireless Stations list. Click Add to add the station to the Trusted Wireless Stations list. If the wireless station is not currently connected, you can enter its address manually. Enter the MAC address of the authorized computer. The MAC address is usually printed on the wireless card, or it may appear in the wireless ADSL modem routers DHCP table. The MAC address will be 12 hexadecimal digits. Click Add to add your entry. You can add several stations to the list, but the entries will be discarded if you do not click Apply. Note: You can copy and paste the MAC addresses from the wireless ADSL modem routers Attached Devices menu into the MAC Address box of this menu. To do this, configure each wireless computer to obtain a wireless link to the wireless ADSL modem router. The computer should then appear in the Attached Devices menu. 4-10 Wireless Configuration August 2005 Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router 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 Apply. You must then access the wireless ADSL modem router from a wired computer to make any further changes. 6. Make sure the Turn Access Control On check box is selected, then click Apply. Now, only devices on this list will be allowed to wirelessly connect to the DG834PN. This prevents unauthorized access to your network. 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. Wireless Configuration 4-11 August 2005 Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router Automatic Open System Shared key Note: The authentication scheme is separate from the data encryption. You can choose an authentication scheme which requires a shared key but still leave the data transmissions unencrypted. If you require strong security, use both the Shared Key and WEP encryption settings. Set your wireless adapter according to the authentication scheme you choose for the DG834PN RangeMax Wireless ADSL Modem Router. Please refer to Authentication and WEP Data Encryption on page D-2 for a full explanation of each of these options, as defined by the IEEE 802.11g wireless communication standard.

1. In the Set Password menu, type a number in Administrator login times out field. The suggested default value is 5 minutes. 2. Click Apply to save your changes or click Cancel to keep the current period. Configuring Basic Firewall Services Basic firewall services you can configure include access blocking and scheduling of firewall security. These topics are presented below. 5-2 Protecting Your Network August 2005 Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router 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. 2.

To delete a keyword or domain, select it from the list, click Delete Keyword, then click Apply. 6. To specify a trusted user, enter that computers IP address in the Trusted IP Address box and click Apply. You can specify one trusted user, which is a computer that will be exempt from blocking and logging. Since the trusted user will be identified by an IP address, you should configure that computer with a fixed IP address. 5-4 Protecting Your Network August 2005 Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router 7. Click Apply to save your settings. Firewall Rules Inbound: Block all access from outside except responses to requests from the LAN side. 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:
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. Figure 5-4: Rules menu Protecting Your Network 5-5 August 2005 Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router 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. 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 5-5:
5-6 Protecting Your Network August 2005 Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router Figure 5-5: Rule example: A Local Public Web Server The parameters are:
Service From this list, select the application or service to be allowed or blocked. The list already displays many common services, but you are not limited to these choices. Use the Services menu to add any additional services or applications that do not already appear. Action Choose how you want this type of traffic to be handled. You can block or allow always, or you can choose to block or allow according to the schedule you have defined in the Schedule menu. Send to LAN Server Enter the IP address of the computer or server on your LAN which will receive the inbound traffic covered by this rule. Protecting Your Network 5-7 August 2005 Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router WAN Users 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. 5-8 Protecting Your Network August 2005 Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router 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 computers IP address constant. Local computers must access the local server using the computers 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) Protecting Your Network 5-9 August 2005 Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router 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. Figure 5-7: Rule example: Blocking Instant Messenger The parameters are:
Service From this list, select the application or service to be allowed or blocked. The list already displays many common services, but you are not limited to these choices. Use the Add Custom Service feature to add any additional services or applications that do not already appear. Action Choose how you want this type of traffic to be handled. You can block or allow always, or you can choose to block or allow according to the schedule you have defined in the Schedule menu. 5-10 Protecting Your Network August 2005 Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router LAN Users These settings determine which packets are covered by the rule, based on their source LAN 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. WAN Users These settings determine which packets are covered by the rule, based on their destination 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 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 logged. Order of Precedence for Rules As you define new rules, they are added to the tables in the Rules menu, as shown in Figure 5-8:
Protecting Your Network 5-11 August 2005 Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router 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 Force (IETF) and published in RFC1700, Assigned Numbers. Service numbers for other applications are typically chosen from the range 1024 to 65535 by the authors of the application. Although the DG834PN already holds a list of many service port numbers, you are not limited to these choices. Use the procedure below to create your own service definitions. 5-12 Protecting Your Network August 2005 Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router How to Define Services 1.

Configuring Advanced Security Setting up a Demilitarized Zone (DMZ) Server The DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router provides a variety of advanced features, such as:
Connecting Automatically, as Required Disabling Port Scan and DOS Protection Responding to a Ping on the Internet WAN Port MTU Size Using the Router as a DHCP Server Configuring Dynamic DNS Configuring Static Routes Flexibility on configuring your LAN TCP/IP settings 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 computers IP address is entered as the Default DMZ Server. Advanced Configuration 7-1 August 2005 Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router 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 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. 7-2 Advanced Configuration August 2005 Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router 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 routers default LAN IP configuration is:
Advanced Configuration 7-3 August 2005 Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router LAN IP addresses192.168.0.1 Subnet mask255.255.255.0 These addresses are part of the Internet Engineering Task Force (IETF)-designated private address range for use in private networks, and should be suitable in most applications. If your network has a requirement to use a different IP addressing scheme, you can make those changes 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. 7-4 Advanced Configuration August 2005 Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router 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. 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. 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 DHCPon 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. Advanced Configuration 7-5 August 2005 Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router 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 routers 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. Subnet Mask The router will deliver the following parameters to any LAN device that requests DHCP:
An IP Address from the range you have defined Gateway IP Address is the routers LAN IP address Primary DNS Server, if you entered a Primary DNS address in the Basic Settings menu;
otherwise, the routers 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 servers 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 routers 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 routers 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. 7-6 Advanced Configuration August 2005 Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router 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. How to Configure LAN TCP/IP Settings 1. Log in to the router at its default LAN address of http://192.168.0.1 with its default User Name of admin, default password of password, or using whatever User Name, Password and LAN address you have chosen for the router. 2. From the Main Menu, under Advanced, click the LAN IP Setup link to view the menu, shown in Figure 7-3:

Advanced Configuration 7-7 August 2005 Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router 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 7-8 Advanced Configuration August 2005 Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router 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. 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 routers address on your LAN is 192.168.0.100. Advanced Configuration 7-9 August 2005 Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router Your companys 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 companys 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. 7-10 Advanced Configuration August 2005 Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router Figure 7-5: Static Routes Table Advanced Configuration 7-11 August 2005 Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router 3. To add or edit a Static Route:
a. Click the Edit button to open the Edit Menu, shown in Figure 7-6. Figure 7-6: Static Route Entry and Edit Menu b. Type a route name for this static route in the Route Name box under the table.

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. 4. Click Apply to have the static route entered into the table. 7-12 Advanced Configuration August 2005 Chapter 8 Troubleshooting This chapter gives information about troubleshooting your DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router. After each problem description, instructions are provided to help you diagnose and solve the problem. For the common problems listed, go to the section indicated. Have I connected the router correctly?
Is the router on?
Go to Basic Functioning on page 8-1. I cant access the routers configuration with my browser. Go to Troubleshooting the Web Configuration Interface on page 8-3. Ive configured the router but I cant access the Internet. Go to Troubleshooting the ISP Connection on page 8-4. I cant remember the routers 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 Routers 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. Troubleshooting 8-1 August 2005 Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router If a ports 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 ports 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 routers configuration to factory defaults. This will set the routers 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. 8-2 Troubleshooting August 2005 Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router Make sure that power is turned on to the connected hub or workstation. Be sure you are using the correct cable:
When connecting the routers WAN ADSL port, use the cable that was supplied with the DG834PN. Troubleshooting the Web Configuration Interface If you are unable to access the routers 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 computers IP address is on the same subnet as the router. If you are using the recommended addressing scheme, your computers 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 computers IP address. Follow the instructions in Appendix C to configure your computer. Note: If your computers 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 routers IP address was changed and you do not know the current IP address, clear the routers configuration to factory defaults. This will set the routers 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. Troubleshooting 8-3 August 2005 Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router 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. 8-4 Troubleshooting August 2005 Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router 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 routers 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 routers 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. Troubleshooting 8-5 August 2005 Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router 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 computers MAC address. In this case:
Inform your ISP that you have bought a new network device, and ask them to use the routers MAC address. OR Configure your router to spoof your computers 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. 5. If all of the steps indicate OK then your PPPoE or PPPoA connection is up and working. 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. Note: Unless you connect manually, the wireless ADSL modem router will not authenticate using PPPoE or PPPoA until data is transmitted to the network. 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. 8-6 Troubleshooting August 2005 Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router 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 routers 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 Troubleshooting 8-7 August 2005 Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router 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 ISPs 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 PCs 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. 8-8 Troubleshooting August 2005 Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router 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 routers 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. Troubleshooting 8-9 August 2005 Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router 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. 8-10 Troubleshooting August 2005 Appendix A Technical Specifications This appendix provides technical specifications for the DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router.
