Federal Communications Commission (FCC) Radiation Exposure Statement This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. In order to avoid the possibility of exceeding the FCC radio frequency exposure limits, human proximity to the antenna shall not be less than 20 cm (8 inches) during normal operation. ii Regulatory Approvals FCC Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communica-
tions. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures:

Consult the dealer or an experienced radio/TV technician for help. To assure continued compliance, any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment.
(Example - use only shielded interface cables when connecting to computer or peripheral devices). FCC Radiation Exposure Statement This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20 centimeters between the radiator and your body. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and
(2) This device must accept any interference received, including interference that may cause undesired operation. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. The antennas used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter. Channel The Wireless Channel sets the radio frequency used for communication. Access Points use a fixed Channel. You can select the Channel used. This allows you to choose a Channel which provides the least interference and best performance. In the USA and Canada, 11 channel are available. If using multiple Access Points, it is better if adjacent Access Points use different Channels to reduce interference. In "Infrastructure" mode, Wireless Stations normally scan all Channels, looking for an Access Point. If more than one Access Point can be used, the one with the strongest signal is used. (This can only happen within an ESS.) If using "Ad-hoc" mode (no Access Point), all Wireless stations should be set to use the same Channel. However, most Wireless stations will still scan all Channels to see if there is an existing "Ad-hoc" group they can join. Note:This equipment marketed in USA is restricted by firmware to only operate on 2.4G channel 1-11

1-4 Introduction v1.0, May 2005 Chapter 2 Wireless Configuration This chapter describes how to configure the wireless features of your DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router. Considerations for a Wireless Network In planning your wireless network, you should consider the level of security required. You should also select the physical placement of your wireless modem router in order to maximize the network speed. For further information, refer to Internet Networking and TCP/IP Addressing: in Appendix B. To ensure proper compliance and compatibility between similar products in your area, the operating channel and region must be set correctly. Observe Performance, Placement, and Range Guidelines The operating distance or range of your wireless connection can vary significantly based on the physical placement of the wireless firewall. The latency, data throughput performance, and notebook power consumption also vary depending on your configuration choices. Note: Failure to follow these guidelines can result in significant performance degradation or inability to wirelessly connect to the router. For complete range/performance specifications, please see Appendix A, Technical Specifications. For best results, place your firewall:
Near the center of the area in which your computers will operate In an elevated location such as a high shelf where the wirelessly connected computers have line-of-sight access (even if through walls) Away from sources of interference, such as computers, microwaves, and cordless phones Away from large metal surfaces Wireless Configuration 2-1 v1.0, May 2005 DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual The time it takes to establish a wireless connection can vary depending on both your security settings and placement. WEP connections can take slightly longer to establish. Also, WEP encryption can consume more battery power on a notebook computer. Implement Appropriate Wireless Security Note: Indoors, computers can connect over 802.11g wireless networks at a maximum range of up to 300 feet. Such distances can allow for others outside of your immediate area to access your network. Unlike wired network data, your wireless data transmissions can extend beyond your walls and can be received by anyone with a compatible adapter. For this reason, use the security features of your wireless equipment. The RangeMax NEXT Wireless ADSL2+ Modem Router provides highly effective security features which are covered in detail in this chapter. Deploy the security features appropriate to your needs.
DG834N
Figure 2-1 There are several ways you can enhance the security of your wireless network:
Restrict Access Based on MAC Address. You can allow only trusted PCs to connect so that unknown PCs cannot wirelessly connect to the DG834N. Restricting access by MAC address adds an obstacle against unwanted access to your network, but the data broadcast over the wireless link is fully exposed. 2-2 Wireless Configuration v1.0, May 2005 DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual Turn Off the Broadcast of the Wireless Network Name SSID. If you disable broadcast of the SSID, only devices that have the correct SSID can connect. This nullifies wireless network discovery feature of some products, such as Windows XP, but the data is still exposed. WEP. Wired Equivalent Privacy (WEP) data encryption provides data security. WEP Shared Key authentication and WEP data encryption will block all but the most determined eavesdropper. This data encryption mode has been superseded by WPA-PSK and WPA2-PSK, and is only available as an option if the Wireless Mode is restricted to 801.11b and 802.11g wireless stations. WPA-PSK (TKIP) + WPA2-PSK (AES). Wi-Fi Protected Access (WPA) data encryption provides data security. The very strong authentication along with dynamic per frame re-keying of WPA make it virtually impossible to compromise. Because this is a relatively new standard, wireless device driver and software availability may be limited. Wireless Configuration 2-3 v1.0, May 2005 DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual Understanding Wireless Settings To configure the Wireless interface of your wireless modem router, click the Wireless link in the main menu of the browser interface. The following Wireless Settings menu will appear after WEP
(Wired Equivalent Privacy) under Security Options is subsequently selected:
Figure 2-2 2-4 v1.0, May 2005 Wireless Configuration DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual The following parameters are in the Wireless Settings menu:
Wireless Network. Name (SSID). The Service Set ID, also known as the wireless network name. Enter a value of up to 32 alphanumeric characters. The same Name (SSID) must be assigned to all wireless devices in your network. The default SSID is NETGEAR, but NETGEAR strongly recommends that you change your network Name to a different value. This value is case sensitive. For example, Wireless is not the same as wireless. Region. Select your region from the drop-down list. This field displays the region of operation for which the wireless interface is intended. It may not be legal to operate the wireless modem router in a region other than the region shown here. Channel. This field determines which operating frequency will be used. If you select the AUTO setting, the RangeMax NEXT Wireless ADSL2+ Modem Router will periodically survey the wireless environment to ensure that it is using the clearest channel. If a clearer channel is available, it may automatically switch channels. Note: After the router switches channels, there may be a slight delay while your wireless computers reconnect to the router. If you want to avoid this possibility, leave channel selection on a fixed channel setting. Mode.
"g & b" allows older 802.11g" and 802.11b wireless stations to access this device. You may want to select this mode if you have a wireless station that is using WEP security and does not support WPA-PSK or WPA2-PSK. Up to 130Mbps allows wireless stations that support speeds up to 130 Mbps. In this case, the router will transmit two streams with different data concurrently on the same channel. You may want to select this mode to restrict channel bandwidth in order to minimize interference with the data transmissions of other access points and wireless stations. Up to 270Mbps means all 802.11g, 802.11b, and faster Pre-N and 802.11N wireless stations can be used. This mode expands the channel bandwidth from 20 MHz to 40 MHz to achieve the 270 Mbps rate. The router selects channel expansion on a frame-by-frame basis to avoid interference with the data transmissions of other access points or wireless stations. This mode is the fastest mode and, since it is compatible with older wireless stations, it is recommended and is the default.

Wireless Configuration 2-15 v1.0, May 2005 DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual 2-16 Wireless Configuration v1.0, May 2005 Chapter 3 Protecting Your Network This chapter describes how to use the basic firewall features of the DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router to protect your network. Protecting Access to Your Wireless Modem Router For security reasons, the wireless modem router has its own user name and password. Also, after a period of inactivity for a set length of time, the administrator login will automatically disconnect. When prompted, enter admin for the wireless modem router user name and password for the wireless modem router password. You can use procedures below to change the wireless modem router's password and the amount of time for the administrators login timeout. Note: The user name and password are not the same as any user name or password your may use to log in to your Internet connection. NETGEAR recommends that you change this password to a more secure password. The ideal password should contain no dictionary words from any language, and should be a mixture of both upper and lower case letters, numbers, and symbols. Your password can be up to 30 characters. How to Change the Built-In Password 1. Log in to the wireless modem router at its default LAN address of http://192.168.0.1 with its default User Name of admin, default password of password, or using whatever Password and LAN address you have chosen for the wireless modem router.

Configuring Basic Firewall Services Basic firewall services you can configure include access blocking and scheduling of firewall security. These topics are presented below. 3-2 Protecting Your Network v1.0, May 2005 DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual Blocking Keywords, Sites, and Services The wireless modem router provides a variety of options for blocking Internet based content and communications services. With its content filtering feature, the RangeMax NEXT Wireless ADSL2+ Modem Router prevents objectionable content from reaching your PCs. The wireless modem router allows you to control access to Internet content by screening for keywords within Web addresses. Key content filtering options include:
Keyword blocking of HTTP traffic. Outbound Service Blocking limits access from your LAN to Internet locations or services that you specify as off-limits. Denial of Service (DoS) protection. Automatically detects and thwarts Denial of Service
(DoS) attacks such as Ping of Death, SYN Flood, LAND Attack and IP Spoofing. Blocking unwanted traffic from the Internet to your LAN. The section below explains how to configure your wireless modem router to perform these functions. How to Block Keywords and Sites The RangeMax NEXT Wireless ADSL2+ Modem Router allows you to restrict access to Internet content based on functions such as Web addresses and Web address keywords. 1. Log in to the wireless modem router at its default LAN address of http://192.168.0.1 with its default User Name of admin, default password of password, or using whatever Password and LAN address you may have previously set for the wireless modem router.

Since the trusted user will be identified by an IP address, you should configure that computer with a fixed IP address. 7. Click Apply to save your settings. Firewall Rules 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 DG834N 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 3-11 for more details. Protecting Your Network 3-5 v1.0, May 2005 DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual To access the rules configuration of the DG834N, click the Firewall Rules link on the main menu, then click Add for either an Outbound or Inbound Service. Figure 3-4 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 wireless modem router uses Network Address Translation (NAT), your network presents only one IP address to the Internet, and outside users cannot directly address any of your local computers. However, by defining an inbound rule you can make a local server (for example, a Web server or game server) visible and available to the Internet. The rule tells the wireless modem router to direct inbound traffic for a particular service to one local server based on the destination port number. This is also known as port forwarding. Note: Some residential broadband ISP accounts do not allow you to run any server processes (such as a Web or FTP server) from your location. Your ISP may periodically check for servers and may suspend your account if it discovers any active services at your location. If you are unsure, refer to the Acceptable Use Policy of your ISP. 3-6 Protecting Your Network v1.0, May 2005 DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual Remember that allowing inbound services opens holes in your firewall. Only enable those ports that are necessary for your network. Following are two application examples of inbound rules:
Inbound Rule Example: A Local Public Web Server If you host a public Web server on your local network, you can define a rule to allow inbound Web
(HTTP) requests from any outside IP address to the IP address of your Web server at any time of day. This rule is shown in Figure 3-5:
Figure 3-5 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, see How to Define Services on page 3-12, 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. 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. Protecting Your Network 3-7 v1.0, May 2005 DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual 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. Inbound Rule Example: Allowing Video conferencing If you want to allow incoming video conferencing to be initiated from a restricted range of outside IP addresses, such as from a branch office, you can create an inbound rule. In the example shown in Figure 3-6, CU-SeeMe connections are allowed only from a specified range of external IP addresses. In this case, we have also specified logging of any incoming CU-SeeMe requests that do not match the allowed parameters. Figure 3-6 Considerations for Inbound Rules If your external IP address is assigned dynamically by your ISP, the IP address may change periodically as the DHCP lease expires. Consider using the Dynamic DNS feature in the Advanced menu so that external users can always find your network. If the IP address of the local server computer is assigned by DHCP, it may change when the computer is rebooted. To avoid this, use the Reserved IP address feature in the LAN IP menu to keep the computers IP address constant. 3-8 v1.0, May 2005 Protecting Your Network DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual Local computers must access the local server using the computers local LAN address
(192.168.0.11 in the example in Figure 3-6 above). Attempts by local computers to access the server using the external WAN IP address will fail. Outbound Rules (Service Blocking) The wireless modem router allows you to block the use of certain Internet services by computers on your network. This is called service blocking or port filtering. You can define an outbound rule to block Internet access from a local computer based on Following is an application example of outbound rules:
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) Outbound Rule Example: Blocking Instant Messenger If you want to block Instant Messenger usage by employees during working hours, you can create an outbound rule to block that application from any internal IP address to any external address according to the schedule that you have created in the Schedule menu. You can also have the wireless modem router log any attempt to use Instant Messenger during that blocked period. Figure 3-7 Protecting Your Network 3-9 v1.0, May 2005 DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual 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. 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. 3-10 Protecting Your Network v1.0, May 2005 DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual Order of Precedence for Rules As you define new rules, they are added to the tables in the Rules menu, as shown in Figure 3-8:
Figure 3-8 For any traffic attempting to pass through the firewall, the packet information is subjected to the rules in the order shown in the Rules Table, beginning at the top and proceeding to the default rules at the bottom. In some cases, the order of precedence of two or more rules may be important in determining the disposition of a packet. The Move button allows you to relocate a defined rule to a new position in the table. Services Services are functions performed by server computers at the request of client computers. For example, Web servers serve Web pages, time servers serve time and date information, and game hosts serve data about other players moves. When a computer on the Internet sends a request for service to a server computer, the requested service is identified by a service or port number. This number appears as the destination port number in the transmitted IP packets. For example, a packet that is sent with destination port number 80 is an HTTP (Web server) request. The service numbers for many common protocols are defined by the Internet Engineering Task Force (IETF) and published in RFC1700, Assigned Numbers. Service numbers for other applications are typically chosen from the range 1024 to 65535 by the authors of the application. Protecting Your Network 3-11 v1.0, May 2005 DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual Although the wireless modem router already holds a list of many service port numbers, you are not limited to these choices.

Configuring Advanced Security Setting up a Demilitarized Zone (DMZ) Server The DG834N RangeMaxTM NEXT Wireless ADSL2+ 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 These features are discussed below. Flexibility on configuring your LAN TCP/IP settings Setting Up A Default DMZ Server The Default DMZ Server feature is helpful when using some online games and videoconferencing applications that are incompatible with NAT. The wireless modem router is programmed to recognize some of these applications and to work properly with them, but there are other applications that may not function well. In some cases, one local computer can run the application properly if that computers IP address is entered as the Default DMZ Server. Advanced Configuration 5-1 v1.0, May 2005 DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual Note: For security reasons, you should avoid using the Default DMZ Server feature. When a computer is designated as the Default DMZ Server, it loses much of the protection of the firewall, and is exposed to many exploits from the Internet. If compromised, the computer can be used to attack your network. Incoming traffic from the Internet is normally discarded by the wireless modem router unless the traffic is a response to one of your local computers or a service that you have configured in the Ports menu. Instead of discarding this traffic, you can have it forwarded to one computer on your network. This computer is called the Default DMZ Server. How to Configure a Default DMZ Server To assign a computer or server to be a Default DMZ server, follow these steps:
1. Log in to the wireless modem router at its default LAN address of http://192.168.0.1 with its default User Name of admin, default password of password, or using whatever Password and LAN address you have chosen for the wireless modem router. 2. From the Main Menu, under Advanced, click the WAN Setup link to view the page shown in Figure 5-1:
Figure 5-1 3. Select the Default DMZ Server check box. 4. Type the IP address for that server. 5. Click Apply to save your changes. 5-2 Advanced Configuration v1.0, May 2005 DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual Connect Automatically, as Required Normally, this option should be enabled, so that an Internet connection will be made automatically, whenever Internet-bound traffic is detected. If this causes high connection costs, you can disable this setting. If disabled, you must connect manually, using the sub-screen accessed from the "Connection Status" button on the Status screen. If you have an "Always on" connection, this setting has no effect. Disable Port Scan and DOS Protection The Firewall protects your LAN against Port Scans and Denial of Service (DOS) attacks. This should be disabled only in special circumstances. Respond to Ping on Internet WAN Port If you want the wireless modem router to respond to a 'ping' from the Internet, select the Respond to Ping on Internet WAN Port check box. This should only be used as a diagnostic tool, since it allows your wireless modem router to be discovered. Do not select this box unless you have a specific reason to do so. MTU Size The normal MTU (Maximum Transmit Unit) value for most Ethernet networks is 1500 Bytes, or 1492 Bytes for PPPoE connections. For some ISPs you may need to reduce the MTU. But this is rarely required, and should not be done unless you are sure it is necessary for your ISP connection. Configuring LAN IP Settings The LAN IP Setup menu allows configuration of LAN IP services such as DHCP and RIP. These features can be found under the Advanced heading in the Main Menu of the browser interface. The wireless modem router is shipped preconfigured to use private IP addresses on the LAN side, and to act as a DHCP server. The wireless modem routers default LAN IP configuration is:
LAN IP addresses192.168.0.1 Subnet mask255.255.255.0 Advanced Configuration 5-3 v1.0, May 2005 DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual These addresses are part of the Internet Engineering Task Force (IETF)-designated private address range for use in private networks, and should be suitable in most applications. If your network has a requirement to use a different IP addressing scheme, you can make those changes in this menu. Figure 5-2 The LAN TCP/IP Setup parameters are:
IP Address: This is the LAN IP address of the wireless modem router. IP Subnet Mask: This is the LAN Subnet Mask of the wireless modem router. Combined with the IP address, the IP Subnet Mask allows a device to know which other addresses are local to it, and which must be reached through a gateway or wireless modem router. RIP Direction: RIP (Router Information Protocol) allows a wireless modem router to exchange routing information with other routers. The RIP Direction selection controls how the Wireless Modem Router sends and receives RIP packets. Both is the default. When set to Both or Out Only, the wireless modem router will broadcast its routing table periodically. When set to Both or In Only, it will incorporate the RIP information that it receives. When set to None, it will not send any RIP packets and will ignore any RIP packets received. RIP Version: This controls the format and the broadcasting method of the RIP packets that the wireless modem router sends. It recognizes both formats when receiving. By default, this is set for RIP-1. RIP-1 is universally supported. RIP-1 is probably adequate for most networks, unless you have an unusual network setup. 5-4 Advanced Configuration v1.0, May 2005 DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual RIP-2 carries more information. Both RIP-2B and RIP-2M send the routing data in RIP-2 format. RIP-2B uses subnet broadcasting. RIP-2M uses multicasting. Note: If you change the LAN IP address of the wireless modem router while connected through the browser, you will be disconnected. You must then open a new connection to the new IP address and log in again. DHCP By default, the wireless modem router will function as a DHCP (Dynamic Host Configuration Protocol) server, allowing it to assign IP, DNS server, and default gateway addresses to all computers connected to the wireless modem router's LAN. The assigned default gateway address is the LAN address of the router. IP addresses will be assigned to the attached PCs from a pool of addresses specified in this menu. Each pool address is tested before it is assigned to avoid duplicate addresses on the LAN. For most applications, the default DHCP and TCP/IP settings of the router are satisfactory. See Internet Networking and TCP/IP Addressing: in Appendix B for an explanation of DHCP and information about how to assign IP addresses for your network. Use Router as DHCP server If another device on your network will be the DHCP server, or if you will manually configure the network settings of all of your computers, clear the Use router as DHCP server check box. Otherwise, leave it selected. Specify the pool of IP addresses to be assigned by setting the Starting IP Address and Ending IP Address. These addresses should be part of the same IP address subnet as the 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. 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 Subnet Mask Advanced Configuration 5-5 v1.0, May 2005 DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual Secondary DNS Server, if you entered a Secondary DNS address in the Basic Settings menu WINS Server, short for Windows Internet Naming Service Server, determines the IP address associated with a particular Windows computer. A WINS server records and reports a list of names and IP address of Windows PCs on its local network. If you connect to a remote network that contains a WINS server, enter the 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. To edit or delete a reserved address entry:

Configuring Dynamic DNS If your network has a permanently assigned IP address, you can register a domain name and have that name linked with your IP address by public Domain Name Servers (DNS). However, if your Internet account uses a dynamically assigned IP address, you will not know in advance what your IP address will be, and the address can change frequently. In this case, you can use a commercial dynamic DNS service that will allow you to register your domain to their IP address, and will forward traffic directed at your domain to your frequently-changing IP address. Advanced Configuration 5-7 v1.0, May 2005 DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual The router contains a client that can connect to a dynamic DNS service provider. To use this feature, you must select a service provider and obtain an account with them. After you have configured your account information in the router, whenever your ISP-assigned IP address changes, your router will automatically contact your dynamic DNS service provider, log in to your account, and register your new IP address. How to Configure Dynamic DNS 1. Log in to the router at its default LAN address of http://192.168.0.1 with its default User Name of admin, default password of password, or using whatever User Name, Password and LAN address you have chosen for the router. 2. From the Main Menu of the browser interface, under Advanced, select Dynamic DNS to display the page below. Figure 5-4 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. 5-8 Advanced Configuration v1.0, May 2005 DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual 9. If your dynamic DNS provider allows the use of wildcards in resolving your URL, you can select the Use wildcards check box to activate this feature. For example, the wildcard feature will cause *.yourhost.dyndns.org to be aliased to the same IP address as yourhost.dyndns.org 10. Click Apply to save your configuration. Note: If your ISP assigns a private WAN IP address such as 192.168.x.x or 10.x.x.x, the dynamic DNS service will not work because private addresses will not be routed on the Internet Using Static Routes Static Routes provide additional routing information to your router. Under normal circumstances, the router has adequate routing information after it has been configured for Internet access, and you do not need to configure additional static routes. You must configure static routes only for unusual cases such as multiple routers or multiple IP subnets located on your network. Static Route Example As an example of when a static route is needed, consider the following case:
Your primary Internet access is through a cable modem to an ISP. You have an ISDN router on your home network for connecting to the company where you are employed. This routers address on your LAN is 192.168.0.100. 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 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 setup would look like Figure 5-6. Advanced Configuration 5-9 v1.0, May 2005 DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual In this example:
The Destination IP Address and IP Subnet Mask fields specify that this static route applies to all 134.177.x.x addresses. The Wireless Modem Router IP Address fields specifies that all traffic for these addresses should be forwarded to the ISDN router at 192.168.0.100. The metric value represents the number of routers between your network and the destination. This is a direct connection so it can be set to the minimum value of 2. Private is selected only as a precautionary security measure in case RIP is activated. How to Configure Static Routes 1. Log in to the router at its default LAN address of http://192.168.0.1 with its default User Name of admin, default password of password, or using whatever User Name, Password and LAN address you have chosen for the router. 2. From the Main Menu of the browser interface, under Advanced, click Static Routes to view the Static Routes menu, shown in Figure 5-5. Figure 5-5 3. To add a Static Route:
5-10 Advanced Configuration v1.0, May 2005 DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual a. Click the Add button to open the Edit Menu, shown in Figure 5-6. Figure 5-6 b. Type a route name for this static route in the Route Name box under the table. This 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. 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 2 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. Advanced Configuration 5-11 v1.0, May 2005 DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual 4. Click Apply. The Static Routes table will update to show the new entry. Figure 5-7 5-12 Advanced Configuration v1.0, May 2005 Chapter 6 Troubleshooting This chapter gives information about troubleshooting your DG834N RangeMaxTM NEXT Wireless ADSL2+ 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 6-1. I cant access the routers configuration with my browser. Go to Troubleshooting the Web Configuration Interface on page 6-3. Ive configured the router but I cant access the Internet. Go to Troubleshooting the ISP Connection on page 6-4. 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 6-9. Basic Functioning After you turn on power to the router, the following sequence of events should occur:
1. When power is first applied, verify that the Power LED is on (see The Routers Front Panel on page 1-2 for an illustration and explanation of the LEDs). 2. After approximately 10 seconds, verify that:
a. The Power LED is not red. b. The LAN port LEDs are lit for any local ports that are connected. c. The WAN port LED is lit. d. The Wireless LED is lit Troubleshooting 6-1 v1.0, May 2005 DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual If a 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. Power LED is Red When the router is turned on, it performs a power-on self test. If the Power LED turns red after a few seconds or at any other time during normal operation, there is a fault within the router. The power LED also turns red when you depress the factory default reset push button, and blinks red 3 times when that button is released. However, in this case, the wireless modem router is working normally. If the power LED turns red to indicate a router fault:
Cycle the power to see if the router recovers. If the power LED is still red one minute after power up:
Cycle the power to see if the router recovers. Clear the 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 6-9. If the error persists, you might have a hardware problem and should contact technical support. LAN or Internet Port LEDs Not On If either the LAN LEDs or Internet LED do not light when the Ethernet connection is made, check the following:
Make sure that the Ethernet cable connections are secure at the router and at the hub or workstation. 6-2 Troubleshooting v1.0, May 2005 DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual Make sure that power is turned on to the connected hub or workstation. Be sure you are using the correct cable:
When connecting the routers Internet ADSL port, use the cable that was supplied with the DG834N. 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. Follow the instructions in Preparing a Computer for Network Access: in Appendix B 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 6-9. Make sure your browser has Java, JavaScript, or ActiveX enabled. If you are using Internet Explorer, click Refresh to be sure the Java applet is loaded. Try quitting the browser and launching it again. Make sure you are using the correct login information. The factory default login name is admin and the password is password. Make sure that CAPS LOCK is off when entering this information. Troubleshooting 6-3 v1.0, May 2005 DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual If the router does not save changes you have made in the Web Configuration Interface, check the following:
When entering configuration settings, be sure to click the Apply button before moving to another menu or tab, or your changes are lost. Click the Refresh or Reload button in the Web browser. The changes may have occurred, but the Web browser may be caching the old configuration. Troubleshooting the ISP Connection If your router is unable to access the Internet, you should check the ADSL connection, then the WAN TCP/IP connection. ADSL link If your router is unable to access the Internet, you should first determine whether you have an ADSL link with the service provider. The state of this connection is indicated with the Internet LED. Internet LED Green or Blinking Green If your Internet LED is green or blinking green, then you have a good ADSL connection. You can be confident that the service provider has connected your line correctly and that your wiring is correct. Internet LED Blinking Amber If your Internet LED is blinking amber, then your wireless modem router is attempting to make an ADSL connection with the service provider. The LED should turn green within several minutes. If the Internet LED does not turn green, disconnect all telephones on the line. If this solves the problem, reconnect the telephones one at a time, being careful to use a microfilter on each telephone. If the microfilters are connected correctly, you should be able to connect all your telephones. If disconnecting telephones does not result in a green Internet LED, there may be a problem with your wiring. If the telephone company has tested the ADSL signal at your Network Interface Device (NID), then you may have poor quality wiring in your house. 6-4 Troubleshooting v1.0, May 2005 DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual Internet LED Off If the Internet LED is off, disconnect all telephones on the line. If this solves the problem, reconnect the telephones one at a time, being careful to use a microfilter on each telephone. If the microfilters are connected correctly, you should be able to connect all your telephones. If disconnecting telephones does not result in a green Internet LED the problem may be one of the following:
Check that the telephone company has made the connection to your line and tested it. Verify that you are connected to the correct telephone line. If you have more than one phone line, be sure that you are connected to the line with the ADSL service. It may be necessary to use a swapper if your ADSL signal is on pins 1 and 4 or the RJ-11 jack. The RangeMax NEXT Wireless ADSL2+ Modem Router uses pins 2 and 3. Obtaining an Internet IP Address If your wireless modem router is unable to access the internet, and your Internet LED is green or blinking green, you should determine whether the wireless modem router is able to obtain an Internet IP address from the ISP. Unless you have been assigned a static IP address, your wireless modem router must request an IP address from the ISP. You can determine whether the request was successful using the browser interface. To check the Internet IP address from the browser interface:
1. Launch your browser and select an external site such as www.netgear.com. 2. Access the Main Menu of the wireless modem 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 modem router has not obtained an IP address from your ISP. If your router is unable to obtain an IP address from the ISP, the problem may be one of the following:
If you have selected a login program, you may have incorrectly set the Service Name, User Name and Password. See Troubleshooting PPPoE or PPPoA, below. Your ISP may check for your computer's host name. Assign the computer Host Name of your ISP account to the wireless modem router in the browser-based Setup Wizard. Your ISP only allows one Ethernet MAC address to connect to Internet, and may check for your computers MAC address. In this case:
Troubleshooting 6-5 v1.0, May 2005 DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual Inform your ISP that you have bought a new network device, and ask them to use the routers MAC address. OR Configure your router to spoof your computers MAC address. This can be done in the Basic Settings menu. Refer to ADSL Modem Wireless Router Setup Manual. Troubleshooting PPPoE or PPPoA The PPPoA or PPPoA connection can be debugged as follows:
1. Access the Main Menu of the router at http://192.168.0.1. 2. Under the Maintenance heading, select the Router Status link. 3. Click the Connection Status button. 4. 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 modem router will continue to attempt to connect indefinitely. If you cannot connect after several minutes, you may be using an incorrect Service Name, User Name or Password. There also may be a provisioning problem with your ISP. Note: Unless you connect manually, the wireless modem router will not authenticate using PPPoE or PPPoA until data is transmitted to the network. Troubleshooting Internet Browsing If your wireless modem router can obtain an IP address but your computer is unable to load any Web pages from the Internet:
Your computer may not recognize any DNS server addresses. A DNS server is a host on the Internet that translates Internet names (such as www addresses) to numeric IP addresses. Typically your ISP will provide the addresses of one or two DNS servers for your use. If you entered a DNS address during the wireless modem routers configuration, reboot your computer and verify the DNS address as described in Preparing a Computer for Network Access: in Appendix B. Alternatively, you can configure your computer manually with DNS addresses, as explained in your operating system documentation. 6-6 Troubleshooting v1.0, May 2005 DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual Your computer may not have the wireless modem router configured as its TCP/IP wireless modem router. If your computer obtains its information from the wireless modem router by DHCP, reboot the computer and verify the wireless modem router address as described in Preparing a Computer for Network Access: in Appendix B. Troubleshooting a TCP/IP Network Using the Ping Utility Most TCP/IP terminal devices and routers contain a ping utility that sends an echo request packet to the designated device. The device then responds with an echo reply. Troubleshooting a TCP/IP network is made very easy by using the ping utility in your computer. Testing the LAN Path to Your Router You can ping the router from your computer to verify that the LAN path to your router is set up correctly. To ping the router from a PC running Windows 95 or later:
1. From the Windows toolbar, click the Start button and select Run. 2. In the field provided, type Ping followed by the IP address of the router, as in this example:
ping 192.168.0.1 3. Click OK. You should see a message like this one:
Pinging <IP address> with 32 bytes of data If the path is working, you see this message:
Reply from < IP address >: bytes=32 time=NN ms TTL=xxx If the path is not working, you see this message:
Request timed out If the path is not functioning correctly, you could have one of the following problems:
Wrong physical connections Make sure the LAN port LED is on. If the LED is off, follow the instructions in LAN or Internet Port LEDs Not On on page 6-2. Check that the corresponding Link LEDs are on for your network interface card and for the hub ports (if any) that are connected to your workstation and router. Troubleshooting 6-7 v1.0, May 2005 DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual 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 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 modem router as described in Preparing a Computer for Network Access: in Appendix B. Check to see that the network address of your PC (the portion of the IP address specified by the netmask) is different from the network address of the remote device. Check that your cable or DSL modem is connected and functioning. If your ISP assigned a host name to your PC, enter that host name as the Account Name in the Basic Settings menu. Your ISP could be rejecting the Ethernet MAC addresses of all but one of your PCs. Many broadband ISPs restrict access by only allowing traffic from the MAC address of your broadband modem, but some ISPs additionally restrict access to the MAC address of a single PC connected to that modem. If this is the case, you must configure your router to clone or spoof the MAC address from the authorized PC. Refer to your ADSL Modem Wireless Router Setup Manual. 6-8 Troubleshooting v1.0, May 2005 DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router Reference Manual 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 4-1). Use the Default Reset button on the rear panel of the router. Use this method for cases when the administration password or IP address is not known. Using the Reset button To restore the factory default configuration settings without knowing the administration password or IP address, you must use the Default Reset button on the rear panel of the router. 1. Press and hold the Default Reset button until the Test LED turns on (about 10 seconds). 2. Release the Default Reset button and wait for the router to reboot. Problems with Date and Time The E-mail menu in the Content Filtering section displays the current date and time of day. The RangeMax NEXT Wireless ADSL2+ Modem Router uses the Network Time Protocol (NTP) to obtain the current time from one of several Network Time Servers on the Internet. Each entry in the log is stamped with the date and time of day. Problems with the date and time function can include:
Date shown is January 1, 2000 Cause: The router has not yet successfully reached a Network Time Server. Check that your Internet access settings are configured correctly. If you have just completed configuring the router, wait at least five minutes and check the date and time again. Time is off by one hour Cause: The router does not automatically sense Daylight Savings Time. In the E-mail menu, check or uncheck the box marked Adjust for Daylight Savings Time.
