2-1v1.0, April 2008Chapter 2 Wireless ConfigurationThis chapter describes how to configure the wireless features of your DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router.This chapter includes:•“Considerations for a Wireless Network”•“Understanding Wireless Settings”•“Understanding Wireless Security”Considerations for a Wireless NetworkIn planning your wireless network, you should consider the level of security required. You should also select the physical placement of your modem router to maximize the network speed. For further information, see the online documentation that you can access from “TCP/IP Networking Basics” in Appendix B.To ensure proper compliance and compatibility between similar products in your area, the operating channel and region must be set correctly.Observe Performance, Placement, and Range GuidelinesThe operating distance or range of your wireless connection can vary significantly based on the physical placement of the wireless firewall. The latency, data throughput performance, and notebook power consumption also vary depending on your configuration choices.For best results, place your firewall:• Near the center of the area in which your computers will operate• In an elevated location such as a high shelf where the wirelessly connected computers have line-of-sight access (even if through walls)Note: Failure to follow these guidelines can result in significant performance degradation or inability to wirelessly connect to the router. For complete range and performance specifications, see Appendix A, “Technical Specifications.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual2-2 Wireless Configurationv1.0, April 2008• Away from sources of interference, such as computers, microwaves, and cordless phones• Away from large metal surfacesThe time it takes to establish a wireless connection can vary depending on both your security settings and placement. Wired Equivalent Privacy (WEP) connections can take slightly longer to establish. Also, WEP encryption can consume more battery power on a notebook computer.Implement Appropriate Wireless Security Unlike wired network data, your wireless data transmissions can extend beyond your walls and can be received by anyone with a compatible adapter. For this reason, use the security features of your wireless equipment. The modem router provides highly effective security features, which are covered in detail in this chapter. Deploy the security features appropriate to your needs.Note: Indoors, computers can connect over wireless networks at a range of several hundred feet. Such distances can allow for others outside of your immediate area to access your network.Figure 2-1DG834N
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference ManualWireless Configuration 2-3v1.0, April 2008There are several ways you can enhance the security of your wireless network:•Restrict access based on MAC address. You can allow only trusted PCs to connect so that unknown PCs cannot wirelessly connect to the modem router. Restricting access by MAC address adds an obstacle against unwanted access to your network, but the data broadcast over the wireless link is fully exposed. •Turn off the broadcast of the wireless network name SSID. If you disable broadcast of the SSID, only devices that have the correct SSID can connect. This nullifies wireless network discovery feature of some products, such as Windows XP, but the data is still exposed.•WEP. Wired Equivalent Privacy (WEP) data encryption provides data security. WEP Shared Key authentication and WEP data encryption block all but the most determined eavesdropper. This data encryption mode has been superseded by WPA-PSK and WPA2-PSK, and is available as an option only if the wireless mode is restricted to 802.11b and 802.11g wireless stations.•WPA-802.1x, WPA2-802.1x. Wi-Fi Protected Access (WPA) with user authentication implemented using IEE 802.1x and RADIUS servers. This option is available only if the wireless mode is restricted to 802.11b and 802.11g wireless stations.•WPA-PSK (TKIP) + WPA2-PSK (AES). Wi-Fi Protected Access (WPA) using a pre-shared key to perform authentication and generate the initial data encryption keys. The very strong authentication along with dynamic per frame re-keying of WPA makes it virtually impossible to compromise.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual2-4 Wireless Configurationv1.0, April 2008Understanding Wireless SettingsTo configure the wireless interface of your modem router, select Wireless Settings in the main menu of the browser interface. The following Wireless Settings screen displays.Table 2-1 describes the information that is displayed in the Wireless Settings screen.Figure 2-2
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference ManualWireless Configuration 2-5v1.0, April 2008Table 2-1. Wireless Settings Settings DescriptionWireless Net-workName (SSID) The SSID is also known as the wireless network name. Enter a 32-character (maximum) name in this field. This field is case-sensitive. The default SSID is NETGEAR, but NETGEAR strongly recommends that you change your net-work name to a different value.In a setting in which there is more than one wireless net-work, different wireless network names provide a means for separating the traffic. Any device you that want to let partici-pate in a wireless network must use the SSID.Region The location where the firewall is used. Select your region from the drop-down list. It might not be legal to operate the modem router in a region other than the region shown here.Channel The wireless channel used by the gateway. If you select the AUTO setting, the modem router will periodically survey the wireless environment to ensure that it is using the clearest channel. If a clearer channel is available, it might automati-cally switch channels.Do not change the wireless channel unless you experience interference (shown by lost connections or slow data trans-fers). If this happens, you might need to experiment with dif-ferent channels to see which is the best. Mode • Up to 270Mbps means that all 802.11g, 802.11b, and faster Draft-N wireless stations can be used. This mode expands the channel bandwidth from 20 MHz to 40 MHz to achieve the 270 Mbps rate. The router selects channel expansion on a frame-by-frame basis to avoid interference with the data transmissions of other access points or wireless stations. This mode is the fastest mode and is compatible with older wireless stations.•Up to 130Mbps allows wireless stations that support speeds up to 130 Mbps. In this case, the router transmits two streams with different data concurrently on the same channel. This mode restricts channel bandwidth to minimize interference with the data transmissions of other access points and wireless stations. It is the default setting.•g & b allows older 802.11g and 802.11b wireless stations to access this device. You might want to select this mode if you have a wireless station that is using WEP security and does not support WPA-PSK or WPA2-PSK.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual2-6 Wireless Configurationv1.0, April 2008Wireless Access PointEnable Wireless Access PointSelected by default, this setting enables the wireless radio, which allows the modem router to work as a wireless access point.Turning off the wireless radio can be helpful for configura-tion, network tuning, or troubleshooting. The Wireless LED on the front of the modem router displays the current status of the wireless access point to let you know if it is disabled or enabled. The wireless access point must be enabled to allow wireless stations to access the Internet.Allow Broadcast Name (SSID).Selected by default, the modem router broadcasts its SSID, allowing wireless stations that have a null (blank) SSID to adopt the correct SSID. If you disable broadcast of the SSID, only devices with the correct SSID can connect. This nullifies the wireless network discovery feature of some products such as Windows XP, but the data is still fully exposed to a determined snoop using specialized test equipment like wireless sniffers. For this reason NETGEAR recommends that you also enable wireless security.Wireless Isolation This feature is disabled by default. If it is enabled, wireless stations cannot communicate with each other or with sta-tions on the wired network. Wireless Sta-tion Access ListTurn Access Control On Access control is disabled by default so that any computer configured with the correct wireless network name or SSID can access to your wireless network. For increased secu-rity, you can restrict access to the wireless network to only specific computers based on their MAC addresses. See “Restricting Wireless Access Based on the Wireless Station Access List.”Table 2-1. Wireless Settings (continued)Settings Description

Then, it dynamically varies the encryption key. WPA-PSK (TKIP) implements most of the IEEE 802.11i standard and is designed to work with all wireless network interface cards, but not all wireless access points. WPA2 implements the full standard, but does not work with some older network cards. See “How to Configure WPA-PSK and WPA2-PSK Security.”WEP This mode is available only if the g and b wireless mode is selected. This mode has been superseded by WPA-PSK and WPA2-PSK, which should be selected if possible. See “How to Configure WEP.”WPA-802.1x This mode is available only if the g and b wireless mode is selected. User authentication is implemented using 802.1x and RADIUS servers. See “How to Configure WPA-802.1x and WPA2-802.1x.”Note: The SSID of any wireless access adapters must match the SSID you specify in the modem router. If they do not match, you will not get a wireless connection.Table 2-1. Wireless Settings (continued)Settings Description

The default channel is 6.This field determines which operating frequency will be used. It should not be necessary to change the wireless channel unless you notice interference problems with another nearby wireless router or access point. Select a channel that is not being used by any other wireless networks within several hundred feet of your modem router. If you set the channel to Auto, the modem router will find the clearest channel for you. However, if that channel becomes noisy, there might be a delay in wireless communications while the modem router searches for a new channel. For more information about the wireless channel frequencies, see the online document that you can access from “Preparing Your Network” in Appendix B. 6. For initial configuration and test, leave the Wireless Card Access List set to allow everyone access by making sure that Turn Access Control On is not selected in the Wireless Station Access List. In addition, leave the encryption strength set to None. 7. Click Apply to save your changes.8. Configure and test your computers for wireless connectivity.Program the wireless adapter of your computers to have the same SSID and channel that you specified in the router. Check that they have a wireless link and can obtain an IP address by DHCP from the modem router.Once your computers have basic wireless connectivity to the modem router, you can configure the advanced wireless security functions of the firewall.Understanding Wireless SecurityIndoors, computers can connect over 802.11n wireless networks at a range that can exceed 300 feet. Such distances can allow for others outside your immediate area to access your network.Unlike wired network data, your wireless data transmissions can extend beyond your walls and can be received by anyone with a compatible adapter. For this reason, use the security features of your wireless equipment. The DG834N modem router provides highly effective security features that are covered in detail in this section. Deploy the security features appropriate to your needs.Note: If you are configuring the firewall from a wireless computer and you change the firewall’s SSID, channel, or security settings, you will lose your wireless connection when you click Apply. You must then change the wireless settings of your computer to match the firewall’s new settings.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference ManualWireless Configuration 2-9v1.0, April 2008Restricting Wireless Access to Your NetworkBy default, any wireless PC that is configured with the correct SSID can access your wireless network. For increased security, the modem router provides several ways to restrict wireless access to your network. You can do the following:• Turn off wireless connectivity completely.• Restrict access based on the wireless network name (SSID).• Restrict access based on the Wireless Card Access List.These options are discussed in the following sections.Restricting Access to Your Network by Turning Off Wireless ConnectivityYou can completely turn off the wireless portion of the modem router. For example, if you use your notebook computer to wirelessly connect to your router and you take a business trip, you can turn off the wireless portion of the router while you are traveling. Other members of your household who use computers connected to the router through Ethernet cables can still use the router.Restricting Wireless Access Based on the Wireless Network Name (SSID)The modem router can restrict wireless access to your network by not broadcasting the wireless network name (SSID). However, by default, this feature is turned off. If you turn this feature on, wireless devices do not “see” your modem router. You must configure your wireless devices to match the wireless network name (SSID) you specify in the modem router.Restricting Wireless Access Based on the Wireless Station Access ListThis list determines which wireless hardware devices will be allowed to connect to the modem router.To restrict access based on MAC addresses:1. Log in to the modem router at its default LAN address of http://192.168.0.1 with its default user name of admin and default password of password, or using whatever LAN address and password you have set up.Warning: The SSID of any wireless access adapters must match the SSID you specify in the modem router. If they do not match, you will not get a wireless connection.

Make sure the Turn Access Control On check box is selected, and then click Apply.Now, only devices on this list will be allowed to wirelessly connect to the modem router. This prevents unauthorized access to your network. How to Configure WPA-PSK and WPA2-PSK SecurityA high-performance client such as the NETGEAR WN511B must connect to the modem router using WPA2-PSK to achieve maximum performance. Wireless clients that connect to the modem router using WPA-PSK run at no more than 802.11g speed. This option allows wireless clients to use either encryption method.To configure WPA-PSK + WPA2-PSK:1. Log in at the default LAN address of http://192.168.0.1, with the default user name of admin and default password of password, or using whatever LAN address and password you have set up.2. Select Wireless Settings below Setup in the main menu of the modem router. 3. Select the WPA-PSK [TKIP] + WPA2-PSK [AES] radio button. The Wireless Settings screen expands to include the WPA-PSK.4.

Click Apply to save your settings.If the wireless network mode is set to g and b, you have the option of selecting WPA-PSK only, WPA2-PSK only, WPA-802.1x, and WPA2-802.1x. For details about the 802.1x authentication options, see “How to Configure WPA-802.1x and WPA2-802.1x” on page 2-14.Note: If you are configuring the modem router from a wireless computer whose MAC address is not in the Trusted Wireless Stations list, and you select trusted wireless stations only, you will lose your wireless connection when you click Apply. You must then access the modem router from a wired computer to make any further changes.Note: Not all wireless adapters support WPA or WPA2. Furthermore, client software is required on the client. Windows XP and Windows 2000 with Service Pack 3 do include the client software that supports WPA. Nevertheless, the wireless adapter hardware and driver must also support WPA. Consult the product document for your wireless adapter and WPA client software for instructions on configuring WPA settings.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual2-12 Wireless Configurationv1.0, April 2008Choosing Alternative Authentication and Encryption MethodsAlternative authentication and encryption methods are available only if you select g and b as the wireless network mode in the Wireless Settings screen. These options will result in a performance impact since wireless communications will be limited to the 802.11g data rate.Restricting wireless access prevents intruders from connecting to your network. However, the wireless data transmissions are still vulnerable to snooping. Using the data encryption settings described in this section will prevent a determined intruder from eavesdropping on your wireless data communications. Also, if you are using the Internet for such activities as purchases or banking, those Internet sites use another level of highly secure encryption called SSL. You can tell if a web site is using SSL because the Web address begins with HTTPS rather than HTTP.How to Configure WEPWired Equivalent Privacy (WEP) security is the most basic and simplest form of wireless security. It is the most often used, but least secure of the available options. WEP Shared Key authentication and WEP data encryption block all but the most determined eavesdropper. This data encryption mode has been superseded by WPA-PSK and WPA2-PSK.To configure WEP data encryption:1. Log in to the modem router at its default LAN address of http://192.168.0.1 with its default user name of admin and default password of password, or using whatever LAN address and password you have set up.2.

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

At the prompt, enter the number of the desired new position and click OK.Inbound Rules (Port Forwarding)Because the modem router uses Network Address Translation (NAT), your network presents only one IP address to the Internet, and outside users cannot directly address any of your local computers. However, by defining an inbound rule you can make a local server (for example, a Web server or game server) visible and available to the Internet. The rule tells the modem router to direct inbound traffic for a particular service to one local server based on the destination port number. This is also known as port forwarding.Figure 3-4Note: Some residential broadband ISP accounts do not allow you to run any server processes (such as a Web or FTP server) from your location. Your ISP might periodically check for servers and might suspend your account if it discovers any active services at your location. If you are unsure, refer to the acceptable use policy of your ISP.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference ManualProtecting Your Network 3-7v1.0, April 2008Remember that allowing inbound services opens holes in your firewall. Enable only those ports that are necessary for your network. Following are two application examples of inbound rules.Inbound Rule Example: A Local Public Web ServerIf you host a public Web server on your local network, you can define a rule to allow inbound Web (HTTP) requests from any outside IP address to the IP address of your Web server at any time of day. This rule is shown in the following figure:The settings are:•Service. From this list, select the application or service to be allowed or blocked. The list already displays many common services, but you are not limited to these choices. Use the Services screen to add any additional services or applications that do not already appear. See “How to Define Services” on page 3-12.•Action. Choose how you want this type of traffic to be handled. You can block or allow always, or you can block or allow according to the schedule you have defined in the Schedule screen.•Send to LAN Server. Enter the IP address of the computer or server on your LAN that will receive the inbound traffic covered by this rule.Figure 3-5
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual3-8 Protecting Your Networkv1.0, April 2008•WAN Users. These settings determine which packets are covered by the rule, based on their source (WAN) IP address. Select the option that you want: –Any: All IP addresses are covered by this rule. –Address range: If this option is selected, you must fill in the Start and Finish fields. –Single address: Enter the required address in the Start field. •Log. You can select whether the traffic will be logged. The choices are:–Never. No log entries will be made for this service.–Always. Any traffic for this service type will be logged.–Match. Traffic of this type that matches the settings and action will be logged.–Not match. Traffic of this type that does not match the settings and action will be logged.Inbound Rule Example: Allowing Video conferencingIf you want to allow incoming video conferencing to be initiated from a restricted range of outside IP addresses, such as from a branch office, you can create an inbound rule. In the example shown in the following figure, CU-SeeMe connections are allowed only from a specified range of external IP addresses. In this case, we have also specified logging of any incoming CU-SeeMe requests that do not match the allowed settings.Figure 3-6
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference ManualProtecting Your Network 3-9v1.0, April 2008Considerations for Inbound Rules• If your external IP address is assigned dynamically by your ISP, the IP address might change periodically as the DHCP lease expires. Consider using the Dynamic DNS screen so that external users can always find your network.• If the IP address of the local server computer is assigned by DHCP, it might change when the computer is rebooted. To avoid this, use the Reserved IP address feature in the LAN IP Setup screen to keep the computer’s IP address constant.• Local computers must access the local server using the computer’s local LAN address (192.168.0.11 in the example in the previous figure). Attempts by local computers to access the server using the external WAN IP address will fail.Outbound Rules (Service Blocking)The modem router allows you to block the use of certain Internet services by computers on your network. This is called service blocking or port filtering. You can define an outbound rule to block Internet access from a local computer based on the following:• IP address of the local computer (source address)• IP address of the Internet site being contacted (destination address)•Time of day• Type of service being requested (service port number)Following is an application example of outbound rules.Outbound Rule Example: Blocking Instant MessengerIf you want to block Instant Messenger usage by employees during working hours, you can create an outbound rule to block that application from any internal IP address to any external address according to the schedule that you create in the Schedule screen.You can specify that the modem router logs any attempt to use Instant Messenger during this blocked period. You can also open or close Instant Messenger ports: see the Firewall Rules screen in the “Order of Precedence for Rules” section on page 3-11.

You can select whether the traffic will be logged. The choices are:–Never. No log entries will be made for this service.–Always. Any traffic for this service type will be logged.–Match. Traffic of this type that matches the settings and action will be logged.–Not match. Traffic of this type that does not match the settings and action will be logged.Order of Precedence for RulesAs you define new rules, they are added to the tables in the Firewall Rules screen, as shown in the following figure:For any traffic attempting to pass through the firewall, the packet information is subjected to the rules in the order shown in the Rules table, beginning at the top and proceeding to the default rules at the bottom. In some cases, the order of precedence of two or more rules might be important in determining the disposition of a packet. The Move button allows you to relocate a defined rule to a new position in the table.Figure 3-8
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual3-12 Protecting Your Networkv1.0, April 2008The Firewall Rules screen also lets you easily open or close Instant Messenger ports:1. Under Instant Messaging (IM) Ports, select a radio button:•Close IM Ports. Specifies to disable instant messaging traffic.•Open IM Ports. Specifies to enable instant messaging traffic. IM ports are open by default.2. Click Apply to save your changes.ServicesServices are functions performed by server computers at the request of client computers. For example, Web servers serve Web pages, time servers serve time and date information, and game hosts serve data about other players’ moves. When a computer on the Internet sends a request for service to a server computer, the requested service is identified by a service or port number. This number appears as the destination port number in the transmitted IP packets. For example, a packet that is sent with destination port number 80 is an HTTP (Web server) request.The service numbers for many common protocols are defined by the Internet Engineering Task Force (IETF) and published in RFC1700, “Assigned Numbers.” Service numbers for other applications are typically chosen from the range 1024 to 65535 by the authors of the application.Although the modem router already holds a list of many service port numbers, you are not limited to these choices. Use the following procedure to create your own service definitions.How to Define Services1.

For security, restrict access to as few external IP addresses as practical:• To allow access from any IP address on the Internet, select Everyone. • To allow access from a range of IP addresses on the Internet, select IP address Range. Enter a beginning and ending IP address to define the allowed range. • To allow access from a single IP address on the Internet, select Only this Computer. Enter the IP address that will be allowed access. 5. Specify the port number that will be used for accessing the management interface.Web browser access usually uses the standard HTTP service port 80. For greater security, you can change the remote management Web interface to a custom port by entering that number in the field provided. Choose a number between 1024 and 65535, but do not use the number of any common service port. The default is 8080, which is a common alternate for HTTP.6. Click Apply to have your changes take effect.Figure 4-10
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual4-18 Managing Your Networkv1.0, April 2008When accessing your modem router from the Internet, you will type your modem router’s WAN IP address in your browser’s Address field, followed by a colon (:) and the custom port number. For example, if your external address is 134.177.0.123 and you use port number 8080, enter the following in your browser:http://134.177.0.123:8080Note: In this case, the http:// must be included in the address.
5-1v1.0, April 2008Chapter 5 Advanced Configuration This chapter describes how to configure the advanced features of your DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router. Configuring Advanced SecurityThe modem router provides a variety of advanced features, which are described in the following sections:•“Setting Up a Default DMZ Server”•“Connecting Automatically, as Required”•“Disabling Port Scan and DOS Protection”•“Responding to a Ping on an Internet WAN Port”•“Setting the MTU Size”•“Disabling the SIP ALG”•“Configuring LAN IP Settings”•“Configuring DHCP”•“Configuring LAN TCP/IP Settings”•“Configuring Dynamic DNS”•“Using Static Routes”•“How to Configure Universal Plug and Play”•“Building Wireless Bridging and Repeating Networks”These features are discussed in the following sections.Setting Up a Default DMZ ServerThe default demilitarized zone (DMZ) server feature is helpful when you use some online games and videoconferencing applications that are incompatible with NAT. The modem router is programmed to recognize some of these applications and to work correctly with them, but there are other applications that might not function well. In some cases, one local computer can run the application correctly if that computer’s IP address is entered as the default DMZ server.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual5-2 Advanced Configurationv1.0, April 2008Incoming traffic from the Internet is usually discarded by the modem router unless the traffic is a response to one of your local computers or a service that you have configured in the Ports screen. Instead of discarding this traffic, you can have it forwarded to one computer on your network. This computer is called the default DMZ server.How to Configure a Default DMZ ServerTo assign a computer or server to be a default DMZ server: 1. Log in to the modem router at its default LAN address of http://192.168.0.1 with its default user name of admin and default password of password, or using whatever user name, password, and LAN address you have chosen for the modem router.2. In the main menu, under Advanced, click WAN Setup to display the following screen.3. Select the Default DMZ Server check box.Note: For security reasons, you should avoid using the default DMZ server feature. When a computer is designated as the default DMZ server, it loses much of the protection of the firewall, and is exposed to many exploits from the Internet. If compromised, the computer can be used to attack your network.Figure 5-1
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference ManualAdvanced Configuration 5-3v1.0, April 20084. Type the IP address for that server. 5. Click Apply to save your changes. Other WAN OptionsThe WAN Setup screen that is shown in Figure 5-1 also allows you perform the following tasks:•Connecting Automatically, as RequiredUsually, this option should be enabled, so that an Internet connection is made automatically, whenever Internet-bound traffic is detected. If this causes high connection costs, you can disable this setting. If this setting is disabled, you must connect manually, using the screen that you access by clicking the Connection Status button on the Status screen.If you have an Always on connection, this setting has no effect.•Disabling Port Scan and DOS ProtectionThe firewall protects your LAN against port scans and denial of service (DOS) attacks. This protection should be disabled only in special circumstances.•Responding to a Ping on an Internet WAN PortIf you want the modem router to respond to a ping from the Internet, select the Respond to Ping on Internet WAN Port check box. This should be used only as a diagnostic tool, since it allows your modem router to be discovered. Do not select this check box unless you have a specific reason to do so.•Setting the MTU SizeThe normal MTU (Maximum Transmit Unit) value for most Ethernet networks is 1500 bytes, or 1492 bytes for PPPoE connections. For some ISPs you might need to reduce the MTU. But this is rarely required, and should not be done unless you are sure it is necessary for your ISP connection.•Disabling the SIP ALGThe Session Initiation Protocol (SIP) Application Level Gateway (ALG) is enabled by default to optimize VoIP phone calls that use the SIP. The Disable SIP ALG check box allows you to disable the SIP ALG. Disabling the SIP ALG might be useful when running certain applications.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual5-4 Advanced Configurationv1.0, April 2008Configuring LAN IP SettingsThe LAN IP Setup screen allows configuration of LAN IP services such as DHCP and RIP. The modem router is shipped preconfigured to use private IP addresses on the LAN side, and to act as a DHCP server. The modem router’s default LAN IP configuration is as follows:• LAN IP address. 192.168.0.1• Subnet mask. 255.255.255.0These addresses are part of the Internet Engineering Task Force (IETF)–designated private address range for use in private networks, and should be suitable in most applications. If your network has a requirement to use a different IP addressing scheme, you can make those changes by opening the LAN IP Setup menu.Under Advanced in the main menu, select LAN IP Setup.The LAN TCP/IP Setup settings are:•IP Address. This is the LAN IP address of the modem router.•IP Subnet Mask. This is the LAN subnet mask of the modem router. Combined with the IP address, the IP subnet mask allows a device to know which other addresses are local to it, and which must be reached through a gateway or modem router.Figure 5-2
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference ManualAdvanced Configuration 5-5v1.0, April 2008•RIP Direction. Router Information Protocol (RIP) allows a modem router to exchange routing information with other routers. The RIP Direction selection controls how the modem router sends and receives RIP packets. Both is the default setting. – When set to Both or Out Only, the modem router broadcasts its routing table periodically. – When set to Both or In Only, the modem router incorporates the RIP information that it receives. – When set to None, the modem router does not send any RIP packets and ignores any RIP packets received. •RIP Version. This controls the format and the broadcasting method of the RIP packets that the modem router sends. It recognizes both formats when receiving. By default, this is set for RIP-1.–RIP-1. This version is universally supported. RIP-1 is probably adequate for most networks, unless you have an unusual network setup. –RIP-2. This version carries more information. Both RIP-2B and RIP-2M send the routing data in RIP-2 format. •RIP-2B. This version uses subnet broadcasting. •RIP-2M. This version uses multicasting.Configuring DHCPBy default, the modem router functions as a Dynamic Host Configuration Protocol (DHCP) server, allowing it to assign IP, DNS server, and default gateway addresses to all computers connected to the modem router’s LAN. The assigned default gateway address is the LAN address of the router. IP addresses are assigned to the attached PCs from a pool of addresses specified in this screen. Each pool address is tested before it is assigned to avoid duplicate addresses on the LAN.For most applications, the default DHCP and TCP/IP settings of the router are satisfactory. See the online document that you can access from “TCP/IP Networking Basics” in Appendix B for an explanation of DHCP and information about how to assign IP addresses for your network. Note: If you change the LAN IP address of the modem router while connected through the browser, you will be disconnected. You must then open a new connection to the new IP address and log in again.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual5-6 Advanced Configurationv1.0, April 2008Use Router as DHCP ServerIf another device on your network will be the DHCP server, or if you will manually configure the network settings of all of your computers, clear the Use router as DHCP server check box. Otherwise, leave it selected. Specify the pool of IP addresses to be assigned by setting the starting IP address and ending IP address. These addresses should be part of the same IP address subnet as the router’s LAN IP address. Using the default addressing scheme, you should define a range between 192.168.0.2 and 192.168.0.254, although you might want to save part of the range for devices with fixed addresses.The router delivers the following settings to any LAN device that requests DHCP:• An IP address from the range you have defined• Subnet mask• Gateway IP address is the router’s LAN IP address• Primary DNS server, if you entered a primary DNS address in the Basic Settings screen; otherwise, the router’s LAN IP address• Secondary DNS server, if you entered a secondary DNS address in the Basic Settings screen• WINS server, short for Windows Internet Naming Service Server, determines the IP address associated with a particular Windows computer. A WINS server records and reports a list of names and IP address of Windows PCs on its local network. If you connect to a remote network that contains a WINS server, enter the server’s IP address here. This allows your PCs to browse the network using the Network Neighborhood feature of Windows.How to Configure Reserved IP AddressesWhen you specify a reserved IP address for a computer on the LAN, that computer will always receives the same IP address each time it access the router’s DHCP server. Reserved IP addresses should be assigned to servers that require permanent IP settings. To reserve an IP address: 1. In the LAN IP Setup screen, click the Add button. 2. In the IP Address field, type the IP address to assign to the computer or server. Choose an IP address from the router’s LAN subnet, such as 192.168.0.x.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference ManualAdvanced Configuration 5-7v1.0, April 20083. Type the MAC address of the computer or server. 4. Click Apply to enter the reserved address into the table. To edit or delete a reserved address entry: 1. Click the button next to the reserved address that you want to edit or delete. 2. Click Edit or Delete. Configuring LAN TCP/IP Settings1. Log in to the router at its default LAN address of http://192.168.0.1 with its default user name of admin and default password of password, or using whatever user name, password, and LAN address you have chosen for the router.2. In the main menu, under Advanced, click LAN IP Setup to display the following screen.Tip: If the computer is already present on your network, you can copy its MAC address from the Attached Devices screen and paste it here.Note: The reserved address will not be assigned until the next time the computer contacts the router’s DHCP server. Reboot the computer or access its IP configuration and force a DHCP release and renew.Figure 5-3
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual5-8 Advanced Configurationv1.0, April 20083. Enter the TCP/IP, DHCP, or reserved IP settings.4. Click Apply to save your changes.Configuring Dynamic DNSIf your network has a permanently assigned IP address, you can register a domain name and have that name linked with your IP address by public Domain Name Servers (DNS). However, if your Internet account uses a dynamically assigned IP address, you will not know in advance what your IP address will be, and the address can change frequently. In this case, you can use a commercial Dynamic DNS service that will allow you to register your domain to their IP address, and will forward traffic directed at your domain to your frequently changing IP address. The router contains a client that can connect to a Dynamic DNS service provider. To use this feature, you must select a service provider and obtain an account with them. After you have configured your account information in the router, whenever your ISP-assigned IP address changes, your router automatically contacts your Dynamic DNS service provider, logs in to your account, and registers your new IP address.How to Configure Dynamic DNS1. Log in to the modem router at its default LAN address of http://192.168.0.1 with its default user name of admin and default password of password, or using whatever user name, password, and LAN address you have chosen for the modem router.2. In the main menu, under Advanced, select Dynamic DNS to display the following screen.Figure 5-4
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference ManualAdvanced Configuration 5-9v1.0, April 20083. Access the website of one of the Dynamic DNS service providers whose names appear in the Service Provider drop-down list, and register for an account. For example, for dyndns.org, go to www.dyndns.org.4. Select the Use a dynamic DNS Service check box. 5. Select the name of your Dynamic DNS service provider. 6. Type the host name that your Dynamic DNS service provider gave you. The Dynamic DNS service provider might call this the domain name. If your URL is myName.dyndns.org, then your host name is myName.7. Type the user name for your Dynamic DNS account. 8. Type the password (or key) for your Dynamic DNS account. 9. If your Dynamic DNS provider allows the use of wildcards in resolving your URL, you can select the Use Wildcards check box to activate this feature. For example, the wildcard feature causes *.yourhost.dyndns.org to be aliased to the same IP address as yourhost.dyndns.org.10. Click Apply to save your configuration. Using Static RoutesStatic 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 ExampleAs an example of when a static route is needed, consider the following case:• Your primary Internet access is through a cable modem to an ISP.• You have an ISDN router on your home network for connecting to the company where you are employed. This router’s address on your LAN is 192.168.0.100.• Your company’s network address is 134.177.0.0.Note: If your ISP assigns a private WAN IP address such as 192.168.x.x or 10.x.x.x, the Dynamic DNS service will not work because private addresses will not be routed on the Internet.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual5-10 Advanced Configurationv1.0, April 2008When you first configured your router, two implicit static routes were created. A default route was created with your ISP as the modem router, and a second static route was created to your local network for all 192.168.0.x addresses. With this configuration, if you attempt to access a device on the 134.177.0.0 network, your router forwards your request to the ISP. The ISP forwards your request to the company where you are employed, and the request is likely to be denied by the company’s firewall.In this case you must define a static route, telling your router that 134.177.0.0 should be accessed through the ISDN router at 192.168.0.100. The static route setup would look like Figure 5-6.In this example:•The Destination IP Address and IP Subnet Mask fields specify that this static route applies to all 134.177.x.x addresses. •The Gateway IP Address field specifies that all traffic for these addresses should be forwarded to the ISDN router at 192.168.0.100. • The value in the Metric field represents the number of routers between your network and the destination. This is a direct connection, so it can be set to the minimum value of 2.•The Private check box is selected only as a precautionary security measure in case RIP is activated.How to Configure Static Routes1. Log in to the modem router at its default LAN address of http://192.168.0.1 with its default user name of admin and default password of password, or using whatever user name, password, and LAN address you have chosen for the modem router.2. In the main menu, under Advanced, select Static Routes to display the Static Routes table.Figure 5-5
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference ManualAdvanced Configuration 5-11v1.0, April 20083. To add a static route:a. Click Add to open the following Static Routes screen.b. Enter a route name for this static route in the Route Name field. This name is for identification purpose only. c. Select Private if you want to limit access to the LAN only. The static route will not be reported in RIP. d. Select Active to make this route effective. e. Enter the destination IP address of the final destination. f. Enter the IP subnet mask for this destination. If the destination is a single host, type 255.255.255.255. g. Enter the gateway IP address, which must be a router on the same LAN segment as the router. h. Enter a number between 2 and 15 as the metric value in the Metric field. This represents the number of routers between your network and the destination. Usually, a setting of 2 or 3 works. Figure 5-6
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual5-12 Advanced Configurationv1.0, April 20084. Click Apply. The Static Routes table is updated to show the new entry.How to Configure Universal Plug and PlayUniversal Plug and Play (UPnP) helps devices, such as Internet appliances and computers, access the network and connect to other devices as needed. UPnP devices can automatically discover the services from other registered UPnP devices on the network.1. Select UPnP on the main menu to display the UPnP screen:2. Fill in the settings on the UPnP screen:•Turn UPnP On. UPnP can be enabled or disabled for automatic device configuration. The default setting for UPnP is enabled. If UPnp is disabled, the modem router does not allow any device to automatically control the resources, such as port forwarding (mapping), of the modem router. Figure 5-7Figure 5-8
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference ManualAdvanced Configuration 5-13v1.0, April 2008•Advertisement Period. The advertisement period is how often the modem router advertises (broadcasts) its UPnP information. This value can range from 1 to 1440 minutes. The default period is 30 minutes. Shorter durations ensure that control points have current device status at the expense of additional network traffic. Longer durations might compromise the freshness of the device status but can significantly reduce network traffic.•Advertisement Time To Live. The time to live for the advertisement is measured in hops (steps) for each UPnP packet sent. A hop is the number of steps allowed to propagate for each UPnP advertisement before it disappears. The number of hops can range from 1 to 255. The default value for the advertisement time to live is 4 hops, which should be fine for most home networks. If you notice that some devices are not being updated or reached correctly, then it might be necessary to increase this value a little.•UPnP Portmap Table. The UPnP Portmap Table displays the IP address of each UPnP device that is currently accessing the modem router and which ports (internal and external) that device has opened. The UPnP Portmap Table also displays what type of port is opened and if that port is still active for each IP address. 3. To save, cancel your changes, or refresh the table:• Click Apply to save the new settings to the modem router. • Click Cancel to disregard any unsaved changes. • Click Refresh to update the portmap table and to show the active ports that are currently opened by UPnP devices.Building Wireless Bridging and Repeating NetworksWith the DG834N modem router, you can build large bridged wireless networks that form an IEEE 802.11n wireless distribution system (WDS). Using the modem router with other access points (APs) and wireless devices, you can connect clients by using their MAC addresses rather than by specifying IP addresses.Here are some examples of wireless bridged configurations:•Point-to-point bridge. The modem router communicates with another bridge-mode wireless station. See “How to Configure a Point-to-Point Bridge Configuration.”•Multi-point bridge. The modem router is the “master” for a group of bridge-mode wireless stations. Then all traffic is sent to this master, rather than to other access points. See “How to Configure a Multi-Point Bridge.”
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual5-14 Advanced Configurationv1.0, April 2008•Repeater with wireless client association. Sends all traffic to the remote access point. See “How to Configure a Repeater with Wireless Client Association.”To view or change these configurations, select Advanced Wireless Settings from the main menu:How to Configure a Point-to-Point Bridge ConfigurationIn point-to-point bridge mode, the DG834N modem router communicates as an access point with another bridge-mode wireless station. As a bridge, wireless client associations are disabled—only wired clients can be connected. You must enter the MAC address of the other bridge-mode wireless station in the field provided. Use wireless security to protect this communication. The following figure shows an example of point-to-point bridge mode.Note: The wireless bridging and repeating feature uses the default security profile to send and receive traffic.Figure 5-9

Disable the DHCP server on AP2 and AP3. AP1 will then be the DHCP server.3. Verify the following for all access points:• The LAN network configuration of the modem router and other access points are configured to operate in the same LAN network address range as the LAN devices.• Only one AP, the DG834N modem router in Figure 5-11, is configured in point-to-multi-point bridge mode; all the others are in point-to-point bridge mode.• All APs, including the DG834N modem router, must be on the same LAN. That is, all the AP LAN IP addresses must be in the same network.• If you are using DHCP, all access points should be set to Obtain an IP address automatically (DHCP Client) in the IP Address Source section of the Basic IP Settings screen.• All APs, including the DG834N modem router, must use the same SSID, channel, authentication mode, if any, and security settings if security is in use.• All point-to-point APs must have the MAC address of AP 1 (the DG834N modem router in the previous figure) in the Remote AP MAC address field.4. Verify connectivity across the LANs. • A computer on any LAN segment should be able to connect to the Internet or share files and printers with any other PCs or servers connected to any of the three LAN segments.Note: Wireless stations configured as they are in Figure 5-11 will not be able to connect to the modem router or access points. If you require wireless stations to access any LAN segment, you can use additional access points configured in wireless access point mode in any LAN segment.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual5-18 Advanced Configurationv1.0, April 2008How to Configure a Repeater with Wireless Client AssociationIn the repeater mode with wireless client association, the DG834N modem router sends all traffic to a remote AP. For the repeater mode, you must enter the MAC address of the remote “parent” access point. Alternatively, you can configure the DG834N modem router as the parent by entering the address of a “child” access point. Note that the following restrictions apply:•You do not have the option of disabling client associations with this DG834N modem router. • You cannot configure a sequence of parent/child APs. You are limited to only one parent AP, although if the DG834N modem router is the parent AP, it can connect with up to four child APs. The following figure shows an example of a Repeater mode configuration. To set up a repeater with wireless client association:1. Configure the operating mode of the devices.• Configure AP 1 (the DG834N modem router in Figure 5-12) on with the MAC address of AP 2 and AP 3 in the first two Remote MAC Address fields.• Configure AP 2 with the MAC address of AP 1 in the Remote MAC Address field.• Configure AP 3 with the MAC address of AP 1 in the Remote MAC Address field.Figure 5-12InternetPCsWireless PC 192.168.0.1AP 1 (parent AP in repeater mode)AP 3 in repeater mode Wireless PCassociatedwith AP 3AP 2 in repeater modeassociatedwith AP2Wireless PCwith AP 1associatedDG834N

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.• Is the router on?Go to “Basic Functioning” on page 6-1.• Have I connected the router correctly?Go to “Basic Functioning” on page 6-1.• I cannot access the router’s configuration with my browser.Go to “Troubleshooting the Web Configuration Interface” on page 6-3.• I have configured the router but I cannot access the Internet.Go to “Troubleshooting the ISP Connection” on page 6-4.• I cannot remember the router’s configuration password.Go to “Restoring the Default Configuration and Password” on page 6-9.• I want to clear the configuration and start over again.Go to “Restoring the Default Configuration and Password” on page 6-9.Basic FunctioningAfter you turn on power to the router, the following sequence of events should occur:1. When power is first applied, verify that the Power LED is on.2. After approximately 10 seconds, verify the following:a. The Power LED is not red.b. The LAN port LEDs are lit for any local ports that are connected.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual6-2 Troubleshootingv1.0, April 2008c. The WAN port LED is lit.d. The Wireless LED is lit.If a port’s LED is lit, a link has been established to the connected device. If a LAN port is connected to a 100 Mbps device, verify that the port’s LED is green. If the port is 10 Mbps, the LED is amber.If any of these conditions does not occur, refer to the appropriate following section.Power LED Is Not OnIf the Power and other LEDs are off when your router is turned on:• Make sure that the power cord is properly connected to your router and that the power supply adapter is properly connected to a functioning power outlet. • Check that you are using the 12 V DC power adapter supplied by NETGEAR for this product.If the error persists, you have a hardware problem and should contact Technical Support.Power LED Is RedWhen the router is turned on, it performs a power-on self-test. If the Power LED turns red after a few seconds or at any other time during normal operation, there is a fault within the router. The Power LED also turns red when you press the default reset button, and blinks red 3 times when you release that button. However, in this case, the modem router is working normally.If the Power LED turns red to indicate a router fault, turn the power off and on to see if the router recovers.If the power LED is still red 1 minute after power up:• Turn the power off and on to see if the router recovers.• Clear the router’s configuration to factory defaults. This sets the router’s IP address to 192.168.0.1. This procedure is explained in “Using the Reset Button” on page 6-9.If the error persists, you might have a hardware problem and should contact Technical Support.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference ManualTroubleshooting 6-3v1.0, April 2008LAN or Internet Port LED Is Not OnIf either the LAN LEDs or Internet LED does not light when the Ethernet connection is made, check the following:• Make sure that the Ethernet cable connections are secure at the router and at the hub or workstation.• Make sure that power is turned on to the connected hub or workstation.• Make sure that you are using the correct cable when connecting the router’s Internet ADSL port. Use the cable that was supplied with the modem router. Troubleshooting the Web Configuration InterfaceIf you are unable to access the router’s Web Configuration Interface from a computer on your local network, check the following:• If you are using an Ethernet-connected computer, check the Ethernet connection between the computer and the router as described in the previous section.• Make sure that your computer’s IP address is on the same subnet as the router. If you are using the recommended addressing scheme, your computer’s address should be in the range of 192.168.0.2 to 192.168.0.254. Follow the instructions in the online document that you can access from “Preparing Your Network” in Appendix B for information about how to configure your computer.• If your router’s IP address was changed and you do not know the current IP address, clear the router’s configuration to factory defaults. This sets the router’s IP address to 192.168.0.1. This procedure is explained in “Using the Reset Button” on page 6-9.• Make sure that your browser has Java, JavaScript, or ActiveX enabled. If you are using Internet Explorer, click Refresh to be sure that the Java applet is loaded.• Try quitting the browser and launching it again.Note: If your computer’s IP address is shown as 169.254.x.x, recent versions of Windows and MacOS will generate and assign an IP address if the computer cannot reach a DHCP server. These auto-generated addresses are in the range of 169.254.x.x. If your IP address is in this range, check the connection from the computer to the router, and reboot your computer.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual6-4 Troubleshootingv1.0, April 2008• Make sure you are using the correct login information. The factory default login name is admin, and the password is password. Make sure that Caps Lock is off when you enter this information.If the router does not save changes you have made in the Web Configuration Interface, check the following:• When entering configuration settings, be sure to click the Apply button before moving to another screen or tab, or your changes are lost. • Click the Refresh or Reload button in the Web browser. The changes might have occurred, but the Web browser might be caching the old configuration.Troubleshooting the ISP ConnectionIf your router is unable to access the Internet, you should check the ADSL connection, then the WAN TCP/IP connection. ADSL LinkIf your router is unable to access the Internet, you should first determine whether you have an ADSL link with the service provider. The state of this connection is indicated with the Internet LED.Internet LED Is Green or Blinking GreenIf your Internet LED is green or blinking green, then you have a good ADSL connection. You can be confident that the service provider has connected your line correctly and that your wiring is correct.Internet LED Is Blinking AmberIf your Internet LED is blinking amber, then your modem router is attempting to make an ADSL connection with the service provider. The LED should turn green within several minutes. If the Internet LED does not turn green, disconnect all telephones on the line. If this solves the problem, reconnect the telephones one at a time, being sure to use a microfilter on each telephone. If the microfilters are connected correctly, you should be able to connect all your telephones.If disconnecting telephones does not result in a green Internet LED, there might be a problem with your wiring. If the telephone company has tested the ADSL signal at your network interface device (NID), then you might have poor-quality wiring in your house.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference ManualTroubleshooting 6-5v1.0, April 2008Internet LED Is OffIf the Internet LED is off, disconnect all telephones on the line. If this solves the problem, reconnect the telephones one at a time, being sure to use a microfilter on each telephone. If the microfilters are connected correctly, you should be able to connect all your telephones.If disconnecting telephones does not result in a green Internet LED, check for the following:• Check that the telephone company has made the connection to your line and tested it.• Verify that you are connected to the correct telephone line. If you have more than one phone line, be sure that you are connected to the line with the ADSL service. It might be necessary to use a swapper if your ADSL signal is on pins 1 and 4 or the RJ-11 jack. The modem router uses pins 2 and 3.Obtaining an Internet IP AddressIf your modem router is unable to access the Internet, and your Internet LED is green or blinking green, you should determine whether the modem router is able to obtain an Internet IP address from the ISP. Unless you have been assigned a static IP address, your modem router must request an IP address from the ISP. You can determine whether the request was successful using the browser interface.To check the Internet IP address from the browser interface: 1. Launch your browser, and select an external site such as www.netgear.com.2. Access the main menu of the modem router’s configuration at http://192.168.0.1. 3. In the main menu, under Maintenance, check that an IP address is shown for the WAN port. If 0.0.0.0 is shown, your modem router has not obtained an IP address from your ISP.If your router is unable to obtain an IP address from the ISP, the problem might be one of the following:• If you have selected a login program, the service name, user name, or password might be incorrectly set. See the following section, “Troubleshooting PPPoE or PPPoA.• Your ISP might check for your computer’s host name. Assign the computer host name of your ISP account to the modem router in the browser-based Setup Wizard.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual6-6 Troubleshootingv1.0, April 2008• Your ISP allows only one Ethernet MAC address to connect to Internet, and might check for your computer’s MAC address. In this case, do one of the following:– Inform your ISP that you have bought a new network device, and ask them to use the router’s MAC address.– Configure your router to spoof your computer’s MAC address. This can be done in the Basic Settings screen. See the ADSL Modem Wireless Router Setup Manual.Troubleshooting PPPoE or PPPoAThe PPPoA or PPPoA connection can be debugged as follows:1. Access the main menu of the router at http://192.168.0.1.2. Under Maintenance, select Router Status.3. Click the Connection Status button.4. If all of the steps indicate OK, then your PPPoE or PPPoA connection is up and working.5. If any of the steps indicates Failed, you can attempt to reconnect by clicking Connect. The modem router will continue to attempt to connect indefinitely.If you cannot connect after several minutes, you might be using an incorrect service name, user name, or password. There also might be a provisioning problem with your ISP.Troubleshooting Internet BrowsingIf your modem router can obtain an IP address, but your computer is unable to load any Web pages from the Internet:• Your computer might not recognize any DNS server addresses. A DNS server is a host on the Internet that translates Internet names (such as www addresses) to numeric IP addresses. Typically your ISP provides the addresses of one or two DNS servers for your use. If you entered a DNS address during the modem router’s configuration, reboot your computer, and verify the DNS address as described in the online document that you can access from “Preparing Your Network” in Appendix B. Alternatively, you can configure your computer manually with DNS addresses, as explained in your operating system documentation.Note: Unless you connect manually, the modem router will not authenticate using PPPoE or PPPoA until data is transmitted to the network.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference ManualTroubleshooting 6-7v1.0, April 2008• Your computer might not have the modem router configured as its TCP/IP modem router.If your computer obtains its information from the modem router by DHCP, reboot the computer, and verify the modem router address as described in the online document that you can access from “Preparing Your Network” in Appendix B.Troubleshooting a TCP/IP Network Using the Ping UtilityMost TCP/IP terminal devices and routers contain a ping utility that sends an echo request packet to the designated device. The device then responds with an echo reply. You can easily troubleshoot a TCP/IP network by using the ping utility in your computer.Testing the LAN Path to Your RouterYou 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 192.168.0.13. Click OK.You should see a message like this one:Pinging <IP address> with 32 bytes of dataIf the path is working, you see this message:Reply from < IP address >: bytes=32 time=NN ms TTL=xxxIf the path is not working, you see this message:Request timed outIf the path is not functioning correctly, you could have one of the following problems:• Wrong physical connections– Make sure that the LAN port LED is on. If the LED is off, follow the instructions in “LAN or Internet Port LED Is Not On” on page 6-3.– Check that the corresponding Link LEDs are on for your network interface card and for the hub ports (if any) that are connected to your workstation and router.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual6-8 Troubleshootingv1.0, April 2008• Wrong network configuration– Verify that the Ethernet card driver software and TCP/IP software are both installed and configured on your PC or workstation.– Verify that the IP address for your router and your workstation are correct and that the addresses are on the same subnet.Testing the Path from Your Computer to a Remote DeviceAfter verifying that the LAN path works correctly, test the path from your PC to a remote device. In the Windows Run screen, type:PING -n 10 IP addresswhere IP address is the IP address of a remote device such as your ISP’s DNS server.If the path is functioning correctly, replies as in the previous section are displayed. If you do not receive replies:• Check that your PC has the IP address of your router listed as the default modem router. If the IP configuration of your PC is assigned by DHCP, this information will not be visible in your PC’s Network Control Panel. Verify that the IP address of the router is listed as the default modem router as described in the online document that you can access from “Preparing Your Network” in Appendix B.• Check to see that the network address of your PC (the portion of the IP address specified by the netmask) is different from the network address of the remote device.• Check that your cable or DSL modem is connected and functioning.• If your ISP assigned a host name to your PC, enter that host name as the account name in the Basic Settings screen.• Your ISP could be rejecting the Ethernet MAC addresses of all but one of your PCs. Many broadband ISPs restrict access by allowing traffic only from the MAC address of your broadband modem, but some ISPs additionally restrict access to the MAC address of a single PC connected to that modem. If this is the case, you must configure your router to “clone” or “spoof” the MAC address from the authorized PC. Refer to your ADSL Modem Wireless Router Setup Manual.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference ManualTroubleshooting 6-9v1.0, April 2008Restoring the Default Configuration and PasswordThis section explains how to restore the factory default configuration settings, changing the router’s administration password to password and the IP address to 192.168.0.1. You can erase the current configuration and restore factory defaults in two ways:• Use the Erase function of the Web Configuration Manager (see “Backing Up, Restoring, and Erasing Your Settings” on page 4-1).• Use the default reset button on the rear panel of the router. Use this method for cases when the administration password or IP address is not known.Using the Reset ButtonTo restore the factory default configuration settings when you do not know the administration password or IP address, you must use the default reset button on the rear panel of the router.1. Press and hold the default reset button until the Power LED turns red (about 5 seconds).2. Release the default reset button. The LED blinks red three times and then turn green when the router has reset to the factory default state. Wait for the router to reboot.Problems with Date and TimeIn the main menu, under Security, select Schedule to display the current date and time of day. The modem router uses the Network Time Protocol (NTP) to obtain the current time from one of several network time servers on the Internet. Each entry in the log is stamped with the date and time of day. Problems with the date and time function can include:• Date shown is January 1, 2000. Cause. The router has not yet successfully reached a network time server. Check that your Internet access is configured correctly. If you have just completed configuring the router, wait at least 5 minutes, and check the date and time again.• Time is off by one hour. Cause. The router does not automatically sense daylight savings time. In the Schedule screen, select the Adjust for Daylight Savings Time check box.
