NETGEAR strongly recommends that you use wireless security. This chapter includes:•“Planning Your Wireless Network•“Manually Configuring Your Wireless Settings” on page 2-4•“Using Push 'N' Connect (WPS) to Configure Your Wireless Network” on page 2-10•“Connecting Additional Wireless Client Devices After WPS Setup” on page 2-14•“Restricting Access to Your Modem Router” on page 2-16Planning Your Wireless NetworkFor compliance and compatibility between similar products in your area, the operating channel and region must be set correctly. To configure the wireless network, you can either specify the wireless settings, or you can use Wi-Fi Protected Setup (WPS) to automatically set the SSID and implement WPA/WPA2 security.• To manually configure the wireless settings, you must know the following:– SSID. The default 11N SSID for the modem router is NETGEAR-DualBand-N. The default 11G SSID is NETGEAR-2.4-G.– The wireless mode (802.11g, or 802.11b) that each wireless adapter supports.– Wireless security option. To successfully implement wireless security, check each wireless adapter to determine which wireless security option it supports. Warning: Computers can connect wirelessly at a range of several hundred feet. This can allow others outside of your immediate area to access your network.
RangeMax Dual Band Wireless-N Modem Router DGND3300 User Manual2-2 Safeguarding Your Networkv1.0, December 2008See “Manually Configuring Your Wireless Settings” on page 2-4.• Push 'N' Connect (WPS) automatically implements wireless security on the modem router while, at the same time, allowing you to automatically implement wireless security on any WPS-enabled devices (such as wireless computers and wireless adapter cards).

This generates a new SSID and implements WPA/WPA2 security.To set up your wireless network using the WPS feature:– Use the WPS button on the side of the modem router (there is also an onscreen WPS button), or enter the PIN of the wireless device. – Make sure that all wireless computers and wireless adapters on the network are Wi-Fi certified and WPA or WPA 2 capable, and that they support WPS configuration.See “Using Push 'N' Connect (WPS) to Configure Your Wireless Network” on page 2-10.Wireless Placement and Range GuidelinesThe range of your wireless connection can vary significantly based on the physical placement of the modem router. The latency, data throughput performance, and notebook power consumption of wireless adapters also vary depending on your configuration choices.For best results, place your modem router according to the following guidelines:• Near the center of the area in which your PCs will operate.• In an elevated location such as a high shelf where the wirelessly connected PCs have line-of-sight access (even if through walls).• Away from sources of interference, such as PCs, microwave ovens, and 2.4 GHz cordless phones.• Away from large metal surfaces.• Put the antenna in a vertical position to provide the best side-to-side coverage. Put the antenna in a horizontal position to provide the best up-and-down coverage. Note: NETGEAR’s Push 'N' Connect feature is based on the Wi-Fi Protected Setup (WPS) standard (for more information, see http://www.wi-fi.org). All other Wi-Fi-certified and WPS-capable products should be compatible with NETGEAR products that implement Push 'N' Connect.
RangeMax Dual Band Wireless-N Modem Router DGND3300 User ManualSafeguarding Your Network 2-3v1.0, December 2008• If using multiple access points, it is better if adjacent access points use different radio frequency channels to reduce interference. The recommended channel spacing between adjacent access points is 5 channels (for example, use Channels 1 and 6, or 6 and 11).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.Wireless Security OptionsIndoors, computers can connect over 802.11g wireless networks at a maximum range of up to 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 Dual Band Wireless-N Modem Router provides highly effective security features which are covered in detail in this chapter. Deploy the security features appropriate to your needs.There are several ways you can enhance the security of your wireless network:•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.•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. Figure 2-1Wireless datasecurity optionsRange: up to 300 foot radius1) Open system: easy but no security.2) WEP: security, but some performance impact.3) WPA-PSK: strong security.4) WPA2-PSK: very strong security.

RangeMax Dual Band Wireless-N Modem Router DGND3300 User Manual2-10 Safeguarding Your Networkv1.0, December 2008Using Push 'N' Connect (WPS) to Configure Your Wireless NetworkIf your wireless clients support Wi-Fi Protected Setup (WPS), you can use this feature to configure the modem router’s SSID and security settings and, at the same time, connect the wireless client securely and easily to the modem router. Look for the symbol on your client device (computers that will connect wirelessly to the modem router are clients). WPS automatically configures the network name (SSID) and wireless security settings for the modem router (if the modem router is in its default state) and broadcasts these settings to the wireless client.Some considerations regarding WPS are:• WPS supports only WPA-PSK and WPA2-PSK wireless security. WEP security is not supported by WPS.• If your wireless network will include a combination of WPS capable devices and non-WPS capable devices, NETGEAR suggests that you set up your wireless network and security settings manually first, and use WPS only for adding additional WPS capable devices. See “Adding Both WPS and Non-WPS Clients” on page 2-14.A WPS client can be added using the Push Button method or the PIN method.•Using the Push Button. This is the preferred method. See the following section, “Using a WPS Button to Add a WPS Client.•Entering a PIN. For information about using the PIN method, see “Using PIN Entry to Add a WPS Client” on page 2-12.Using a WPS Button to Add a WPS ClientAny wireless computer or wireless adapter that will connect to the modem router wirelessly is a client. The client must support a WPS button, and must have a WPS configuration utility, such as the NETGEAR Smart Wizard or Atheros Jumpstart.To use the modem router WPS button to add a WPS client: Note: NETGEAR’s Push 'N' Connect feature is based on the Wi-Fi Protected Setup (WPS) standard (for more information, see http://www.wi-fi.org).

RangeMax Dual Band Wireless-N Modem Router DGND3300 User Manual3-8 Protecting Your Networkv1.0, December 2008Blocking Access to Internet ServicesThe 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. 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 your network sends a request for service to a server computer on the Internet, 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.LAN users (Outbound Services only)These settings determine which computers on your network are affected by this rule, based on their source (LAN) IP address. Select the desired option: •Any. All local 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 fields. Send to LAN Server (Inbound Services only)Enter the IP address of the PC or Server on your LAN that will receive the inbound traffic covered by this rule. WAN Servers These settings determine which Internet locations are covered by the rule, based on their destination (WAN) IP address. Select the desired option: •Any. All local 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 fields. Log This determines whether packets covered by this rule are logged. Select the desired action: •Always. Always log traffic considered by this rule, whether it matches or not. This is useful when debugging your rules. •Never. Never log traffic considered by this rule, whether it matches or not. •Match. Log traffic only it matches this rule. (The action is determined by this rule.) •Not Match. Log traffic that is considered by this rule, but does not match (The action is NOT determined by this rule.) Table 3-1.

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.RIP Direction RIP (Router Information Protocol) allows a modem router to exchange routing information with other routers. This setting controls how the modem router sends and receives RIP packets. Both is the default. •Both or Out Only. The modem router broadcasts its routing table periodically. •Both or In Only. The modem router incorporates the RIP information that it receives. •None. The modem router 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 modem router sends. It recognizes both formats when receiving. By default, this is RIP-1. • RIP-1 is universally supported. It is adequate for most networks, unless you have an unusual network setup. • RIP-2 carries more information. Both RIP-2B and RIP-2M send the routing data in RIP-2 format. RIP-2B uses subnet broadcasting. RIP-2M uses multicasting.DHCP ServerFor more informationUse Router as a DHCP ServerThis check box is usually selected so that the modem router functions as a Dynamic Host Configuration Protocol (DHCP) server.

RangeMax Dual Band Wireless-N Modem Router DGND3300 User Manual5-4 Customizing Your Network Settingsv1.0, December 2008Using the Modem Router as a DHCP ServerBy default, the modem router functions as a 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 modem router. The modem router assigns IP addresses to the attached computers 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 modem router are satisfactory. Click the link to the online document “TCP/IP Networking Basics” in Appendix B for an explanation of DHCP and information about how to assign IP addresses for your network. 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 modem router’s LAN IP address. Using the default addressing scheme, you should define a range between 192.168.1.2 and 192.168.1.254, although you might wish to save part of the range for devices with fixed addresses.The modem router delivers the following parameters to any LAN device that requests DHCP:• An IP Address from the range you have defined• Subnet Mask• Gateway IP Address (the modem router’s LAN IP address)• Primary DNS Server (if you entered a primary DNS address in the Basic Settings screen; otherwise, the modem router’s LAN IP address)• Secondary DNS Server (if you entered a secondary DNS address in the Basic Settings screen)To use another device on your network as the DHCP server, or to manually configure the network settings of all of your computers, clear the Use Router as DHCP Server check box. Otherwise, leave it selected. If this service is not selected and no other DHCP server is available on your network, you will need to set your computers’ IP addresses manually or they will not be able to access the modem router.Address ReservationWhen you specify a reserved IP address for a computer on the LAN, that computer always receives the same IP address each time it accesses the modem router’s DHCP server. Reserved IP addresses should be assigned to computers or servers that require permanent IP settings. To reserve an IP address: 1. Click Add.
RangeMax Dual Band Wireless-N Modem Router DGND3300 User ManualCustomizing Your Network Settings 5-5v1.0, December 20082. In the IP Address field, type the IP address to assign to the computer or server. (Choose an IP address from the modem router’s LAN subnet, such as 192.168.1.x.) 3. 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. Select the radio button next to the reserved address you want to edit or delete. 2. Click Edit or Delete.Using a Dynamic DNS ServiceIf your Internet Service Provider (ISP) gave you 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 do 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, which allows you to register your domain to their IP address, and forwards traffic directed at your domain to your frequently changing IP address.Your modem router contains a client that can connect to the Dynamic DNS service provided by DynDNS.org. You must first visit their website at www.dyndns.org and obtain an account and host name, which you configure in the modem router. Then, whenever your ISP-assigned IP address 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 is not assigned until the next time the computer contacts the modem router’s DHCP server. Reboot the computer or access its IP configuration and force a DHCP release and renew.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 are not routed on the Internet.
RangeMax Dual Band Wireless-N Modem Router DGND3300 User Manual5-6 Customizing Your Network Settingsv1.0, December 2008changes, your modem router automatically contacts the Dynamic DNS service provider, logs in to your account, and registers your new IP address. If your host name is hostname, for example, you can reach your modem router at hostname.dyndns.org.From the main menu, under Advanced, select Dynamic DNS to display the Dynamic DNS screen.To configure Dynamic DNS:1. Register for an account with one of the Dynamic DNS service providers whose names appear in the Service Provider list. For example, for DynDNS.org, select www.dyndns.org.2. Select the Use a Dynamic DNS Service check box. 3. Select the name of your Dynamic DNS service provider. 4. Type the host name (or domain name) that your Dynamic DNS service provider gave you.5. Type the user name for your Dynamic DNS account. This is the name that you use to log in to your account, not your host name.6. Type the password (or key) for your Dynamic DNS account. 7. 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.8. Click Apply to save your configuration.Figure 5-2

From the main menu, under Advanced, click WAN Setup to view the WAN Setup screen. The WAN Setup fields are described in the following table:Figure 5-3Table 5-2. WAN Setup SettingsSetting DescriptionDisable SPI Firewall The Stateful Packet Inspection (SPI) firewall protects your network and computers against attacks and intrusions. A stateful packet firewall carefully inspects incoming traffic packets, looking for known exploits such as malformed, oversized, or out-of-sequence packets. The firewall should be disabled only in special circumstances, such as when you are troubleshooting application issues. Default DMZ Server This feature is sometimes helpful when you are using some online games and videoconferencing. Be careful when using this feature because it makes the firewall security less effective. See the following section, Configuring Static Routes.Respond to Ping on Internet WAN PortIf you want the modem router to respond to a ping from the Internet, select this 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.
RangeMax Dual Band Wireless-N Modem Router DGND3300 User Manual5-8 Customizing Your Network Settingsv1.0, December 2008Setting Up a Default DMZ ServerThe default DMZ server feature is helpful when you are using some online games and videoconferencing applications that are incompatible with Network Address Translation (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.Incoming 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 Port Forwarding/Port Triggering 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.The WAN Setup screen lets you configure a default DMZ server.To assign a computer or server to be a default DMZ server: 1. In the last Default DMZ Server field, type the last digit of the IP address for that computer. To remove the default DMZ server, enter 0 (zero).2. Select the Default DMZ Server check box, and click Apply.MTU Size (in bytes) The 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. This is rarely required, and should not be done unless you are sure it is necessary for your ISP connection. See “Changing the MTU Size” on page 6-6.NAT Filtering Network Address Translation (NAT) determines how the modem router processes inbound traffic. Secured NAT provides a secured firewall to protect the computers on the LAN from attacks from the Internet, but might prevent some Internet games, point-to-point applications, or multimedia applications from functioning. Open NAT provides a much less secured firewall, but allows almost all Internet applications to function. Warning: DMZ servers pose a security risk. A computer designated as the default DMZ server loses much of the protection of the firewall and is exposed to exploits from the Internet. If compromised, the DMZ server computer can be used to attack other computers on your network.Table 5-2. WAN Setup SettingsSetting Description
RangeMax Dual Band Wireless-N Modem Router DGND3300 User ManualCustomizing Your Network Settings 5-9v1.0, December 2008Configuring Static RoutesStatic routes provide additional routing information to your modem router. Under usual circumstances, the modem 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.As an example of when a static route is needed, consider the following case:• Your primary Internet access is through a cable modem to an ISP.• You have an ISDN router on your home network for connecting to the company where you are employed. This router’s address on your LAN is 192.168.1.100.• Your company’s network address is 134.177.0.0.When you first configured your modem router, two implicit static routes were created. A default route was created with your ISP as the gateway, and a second static route was created to your local network for all 192.168.1.x addresses. With this configuration, if you attempt to access a device on the 134.177.0.0 network, your modem 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 modem router that 134.177.0.0 should be accessed through the ISDN router at 192.168.1.100. 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 192.168.1.100. •A Metric value of 1 will work since the ISDN router is on the LAN. •Private is selected only as a precautionary security measure in case RIP is activated.

Wireless repeating is a type of Wireless Distribution System (WDS).The following figure shows a wireless repeating scenario: To set up a wireless network using WDS, the following conditions must be met for both APs:• Both APs must use the same SSID, wireless channel, and encryption mode (see “Manually Configuring Your Wireless Settings” on page 2-4 or “Using Push 'N' Connect (WPS) to Configure Your Wireless Network” on page 2-10).• Both APs must be on the same LAN IP subnet. That is, all the AP LAN IP addresses are in the same network.• All LAN devices (wired and wireless computers) must be configured to operate in the same LAN network address range as the APs.Warning: If you use the wireless repeating function, your options for wireless security are limited to None or WEP. For more information about wireless security, see Chapter 2, “Safeguarding Your Network.”Figure 5-6Repeater APBase Station AP
RangeMax Dual Band Wireless-N Modem Router DGND3300 User Manual5-12 Customizing Your Network Settingsv1.0, December 2008• When the modem router is in dual band mode (the Mode field on the Wireless Settings screen is set to Up to 270 Mbps at 5 GHz and 54 Mbps at 2.4 GHz), the WDS function works only in 5GHz 11N mode. To use the 2.4GHz 11g protocol with WDS, set the Mode field in the Wireless Settings screen to Up to 130 Mbps at 2.4 GHz. If you make changes in the Wireless Settings screen, click Apply so that they take effect.Wireless Repeating FunctionYou can view or change wireless repeater settings for the modem router. From the main menu of the browser interface, under Advanced, click Wireless Repeating Function to display the Wireless Repeating Function screen.The modem router supports two modes of the wireless repeating function, and allows you to control wireless client association:•Wireless Repeater. The modem router sends all traffic from its local wireless or wired computers to a remote AP. To configure this mode, you must know the MAC address of the remote parent AP. •Wireless Base Station. The modem router acts as the parent AP, bridging traffic to and from the child repeater AP, as well as handling wireless and wired local computers. To configure this mode, you must know the MAC addresses of the child repeater AP.•Disable Wireless Client Association. Usually this check box is cleared so that the modem router is an access point for wireless computers. Figure 5-7

The modem router still communicates with wire-connected LAN devices. Setting Up the Base StationThe wireless repeating function works only in hub and spoke mode. The units cannot be daisy chained. You must know the wireless settings for both units. You must know the MAC address of the remote unit. First, set up the base station, and then set up the repeater. To set up the base station:1. Set up both units with exactly the same wireless settings (SSID, mode, channel, and security). Note that the wireless security option must be set to None or WEP.2. Log into the modem router base unit, under the Advanced heading, select Wireless Repeating Function to display the Wireless Repeating Function screen.3. Select the Enable Wireless Repeating Function check box and the Wireless Base Station radio button.4. Enter the MAC address for the repeater units.5. Click Apply to save your changes.Figure 5-8

If you are using the same model of modem router for both the base station and repeaters, you must change the LAN IP address for each repeater to a different IP address in the same subnet (see “Using the LAN Setup Options” on page 5-1). 2. Log in to the router that will be the repeater. Check the Wireless Settings screen, and verify that the wireless settings match the base unit exactly. The wireless security option must be set to WEP or None.3. In the Wireless Repeating Function screen, select the Enable Wireless Repeater Mode radio button.This IP address must be in the same subnet as the base station but different from the LAN IP of the base station.4. Fill in the Base Station MAC Address field.5. Click Apply to save your changes.6. Verify connectivity across the LANs. A computer on any wireless or wired LAN segment of the modem router should be able to connect to the Internet or share files and printers with any other wireless or wired computer or server connected to the other AP.Note: If you are using the DGND3300 base station with a non-NETGEAR modem router as the repeater, you might need to change additional configuration settings. In particular, you should disable the DHCP server function on the wireless repeater AP.Note: Failing to change the LAN IP address will cause an IP address conflict in the network because the factory default LAN IP is the same for both units.
RangeMax Dual Band Wireless-N Modem Router DGND3300 User ManualFine-Tuning Your Network 6-1v1.0, December 2008Chapter 6Fine-Tuning Your NetworkThis chapter describes features to help you manage your RangeMax Dual Band Wireless-N Modem Router.This chapter includes the following sections:•“Assessing Your Speed Requirements” on page 6-2•“Optimizing Your Network Bandwidth” on page 6-3•“Optimizing Wireless Performance” on page 6-5•“Changing the MTU Size” on page 6-6Common connection types and their speed and security considerations are:•Broadband Internet. Your Internet connection speed is determined by your modem type, (ADSL), as well as the connection speed of the sites to which you connect, and general Internet traffic. ADSL modem connections are asymmetrical, meaning they have a lower data rate to the Internet (upstream) than from the Internet (downstream). Keep in mind that when you connect to another site that also has an asymmetrical connection, the data rate between your sites is limited by each side’s upstream data rate. A typical residential ADSL connection provides a downstream throughput of about 1 to 3 megabits per second (Mbps). Newer technologies such as ADSL2+ and Fiber to the Home (FTTH) will increase the connection speed to tens of Mbps.•Wireless. Your modem router provides a wireless data throughput of up to 300 Mbps using technology called multiple input, multiple output (MIMO), in which multiple antennas transmit multiple streams of data. The use of multiple antennas also provides excellent range and coverage. With the introduction of the newer WPA and WPA2 encryption and authentication protocols, wireless security is extremely strong.To get the best performance, use RangeMax NEXT adapters for your computers. Although your modem router is compatible with older 802.11b and 802.11g adapters, the use of these older wireless technologies in your network can result in lower throughput overall (typically less than 10 Mbps for 802.11b and less than 40 Mbps for 802.11g). In addition, many older wireless products do not support the latest security protocols, WPA and WPA2.
RangeMax Dual Band Wireless-N Modem Router DGND3300 User Manual6-2 Fine-Tuning Your Networkv1.0, December 2008•Powerline. For connecting rooms or floors that are blocked by obstructions or are distant vertically, consider networking over your building’s AC wiring. NETGEAR’s Powerline HD family of products delivers up to 200 Mbps to any outlet, while the older-generation XE family of products delivers 14 Mbps or 85 Mbps. Data transmissions are encrypted for security, and you can configure an individual network password to prevent neighbors from connecting.The Powerline HD family of products can coexist on the same network with older-generation XE family products or HomePlug 1.0 products, but they are not interoperable with these older products.•Wired Ethernet. As gigabit-speed Ethernet ports (10/100/1000 Mbps) become common on newer computers, wired Ethernet remains a good choice for speed, economy, and security. Gigabit Ethernet can extend up to 100 meters with twisted-pair wiring of CAT-5e or better. A wired connection is not susceptible to interference, and eavesdropping would require a physical connection to your network.Assessing Your Speed RequirementsBecause your Internet connection is likely to operate at a much lower speed than your local network, faster local networking technologies might not improve your Internet experience. However, many emerging home applications require high data rates. For example:• Streaming HD video requires 10 to 30 Mbps per stream. Because latency and packet loss can disrupt your video, plan to provide at least twice the capacity you need.• Streaming MP3 audio requires less than 1 Mbps per stream and does not strain most modern networks. Like video, however, streaming audio is also sensitive to latency and packet loss, so a congested network or a noisy link can cause problems.Note: Actual data throughput will vary. Network conditions and environmental factors, including volume of network traffic, building materials and construction, and network overhead, can lower actual data throughput rate.
RangeMax Dual Band Wireless-N Modem Router DGND3300 User ManualFine-Tuning Your Network 6-3v1.0, December 2008• Backing up computers over the network has become popular due to the availability of inexpensive mass storage. Table 6-1 shows the time to transfer 1 gigabyte (GB) of data using various networking technologies.Optimizing Your Network BandwidthAs your network grows, it might consist of several segments of different networking technologies, each providing different throughput. In planning your network, you should first consider which devices will have the heaviest traffic flow between them. Examples are:• A media center in one room streaming high-definition video from a server in another room• A storage device that is used for backing up your computersTable 6-1.

RangeMax Dual Band Wireless-N Modem Router DGND3300 User Manual6-4 Fine-Tuning Your Networkv1.0, December 2008Next, consider the throughput of your network devices. Where possible, make the heaviest-traffic connections using higher-speed technologies, with no lower-speed bottlenecks in the path. Figure 6-1 shows a sample network using multiple networking technologies. In this network, the two PCs with Gigabit (1000 Mbps) Ethernet adapters have a gigabit connection through the GS605 switch to the storage server. This connection should allow for extremely fast backups or quick access to large files on the server. The PC connected through a pair of Powerline HD adapters is limited to the 200 Mbps speed of the Powerline HD connection. Although any of the links in this example would be sufficient for high-traffic applications such as streaming HD video, the use of older devices such as 10 Mbps Ethernet or 802.11b wireless would create a significant bottleneck.Figure 6-1RangeMax Dual Band Wireless-N Modem Router
RangeMax Dual Band Wireless-N Modem Router DGND3300 User ManualFine-Tuning Your Network 6-5v1.0, December 2008Optimizing Wireless PerformanceThe speed and operating distance or range of your wireless connection can vary significantly based on the physical placement of the wireless router. You should choose a location for your router that will maximize the network speed.The following list describes how to optimize wireless router performance.•Identify critical wireless links.If your network has several wireless devices, decide which wireless devices need the highest data rate, and locate the router near them. Many wireless products have automatic data-rate fallback, which allows increased distances without loss of connectivity. This also means that devices that are farther away might be slower. Therefore, the most critical links in your network are those where the traffic is high and the distances are great. Optimize those first. •Choose placement carefully.For best results, place your router:– 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).– Avoid obstacles to wireless signals.– Keep wireless devices at least 2 feet from large metal fixtures such as file cabinets, refrigerators, pipes, metal ceilings, reinforced concrete, and metal partitions.– Keep away from large amounts of water such as fish tanks and water coolers.• Reduce interference.– Avoid windows unless communicating between buildings.– Place wireless devices away from various electromagnetic noise sources, especially those in the 2400–2500 MHz frequency band. Common noise-creating sources are:• Computers and fax machines (no closer than 1 foot)• Copying machines, elevators, and cell phones (no closer than 6 feet)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, click the link to the online document “Wireless Networking Basics” in Appendix B.
RangeMax Dual Band Wireless-N Modem Router DGND3300 User Manual6-6 Fine-Tuning Your Networkv1.0, December 2008• Microwave ovens (no closer than 10 feet)• Choose your settings.– Use a scanning utility to determine what other wireless networks are operating nearby, and choose an unused channel.– Turn off SSID broadcast, and change the default SSID. Other nearby devices might automatically try to connect to your network several times a second, which can cause significant performance reduction. • Use WMM to improve the performance of voice and video traffic over the wireless link.Changing the MTU SizeThe Maximum Transmission Unit (MTU) is the largest data packet a network device transmits. When one network device communicates across the Internet with another, the data packets travel through many devices along the way. If any device in the data path has a lower MTU setting than the other devices, the data packets must be split or “fragmented” to accommodate the one with the smallest MTU. The best MTU setting for NETGEAR equipment is often just the default value, and changing the value might fix one problem but cause another. Leave MTU unchanged unless one of these situations occurs:• You have problems connecting to your ISP or other Internet service, and the technical support of either the ISP or NETGEAR recommends changing the MTU setting. These might require an MTU change:– A secure website that won’t open, or displays only part of a Web page–Yahoo e-mail–MSN– America Online’s DSL service• You use VPN and have severe performance problems.• You used a program to optimize MTU for performance reasons, and now you have connectivity or performance problems.Note: An incorrect MTU setting can cause Internet communication problems such as the inability to access certain Web sites, frames within Web sites, secure login pages, or FTP or POP servers.
RangeMax Dual Band Wireless-N Modem Router DGND3300 User ManualFine-Tuning Your Network 6-7v1.0, December 2008If you suspect an MTU problem, a common solution is to change the MTU to 1400. If you are willing to experiment, you can gradually reduce the MTU from the maximum value of 1500 until the problem goes away. Table 6-2 describes common MTU sizes and applications. To change the MTU size:1. In the main menu, under Advanced, select WAN Setup. 2. In the MTU Size field, enter a new size between 64 and 1500.3. Click Apply to save the new configuration.Universal Plug and PlayUniversal Plug and Play (UPnP) helps devices, such as Internet appliances and computers, to 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.Table 6-2. Common MTU SizesMTU Application1500 The largest Ethernet packet size and the default value. This is the typical setting for non-PPPoE, non-VPN connections, and is the default value for NETGEAR routers, adapters, and switches.1492 Used in PPPoE environments.1472 Maximum size to use for pinging. (Larger packets are fragmented.)1468 Used in some DHCP environments.1460 Usable by AOL if you don't have large e-mail attachments, for example.1436 Used in PPTP environments or with VPN.1400 Maximum size for AOL DSL.576 Typical value to connect to dial-up ISPs.Note: If you use applications such as multiplayer gaming, peer-to-peer connections, real-time communications such as instant messaging, or remote assistance (a feature in Windows XP), you should enable UPnP.
RangeMax Dual Band Wireless-N Modem Router DGND3300 User Manual6-8 Fine-Tuning Your Networkv1.0, December 2008To turn on Universal Plug and Play:1. From the main menu, under Advanced, click UPnP. The UPnP screen displays. 2. The available settings and information in this screen are:•Turn UPnP On. UPnP can be enabled or disabled for automatic device configuration. The default setting for UPnP is disabled. If this check box is not selected, the router does not allow any device to automatically control the resources, such as port forwarding (mapping) of the router. •Advertisement Period. The advertisement period is how often the router 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. The time to live hop count is the number of steps a broadcast packet is 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.•UPnP Portmap Table. The UPnP Portmap Table displays the IP address of each UPnP device that is currently accessing the router and which ports (Internal and External) that device has opened. The UPnP Portmap Table also displays what type of port is open and whether that port is still active for each IP address. 3. Click Apply to save your settings.Figure 6-2

RangeMax Dual Band Wireless-N Modem Router DGND3300 User Manual7-4 Troubleshootingv1.0, December 2008Cannot Access the Router MenuIf you are unable to access the router’s menu 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 modem router.• Make sure your computer’s IP address is on the same subnet as the router. If you are using the recommended addressing scheme, your computer’s address should be in the range of 192.168.0.2 to 192.168.0.254. Refer to “Preparing Your Network” in Appendix B to find your computer’s IP address. • If your computer’s IP address is shown as 169.254.x.x:, it might because recent versions of Windows and MacOS generate and assign an IP address if the computer cannot reach a DHCP server. These auto-generated addresses are in the range of 169.254.x.x. If your IP address is in this range, check the connection from the computer to the router and reboot your computer.• If your router’s IP address was changed and you do not know the current IP address, clear the router’s configuration to factory defaults. This will set the router’s IP address to 192.168.0.1. This procedure is explained in “Restoring the Factory Configuration Settings” in Appendix A.• 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 login name is admin and the default password is password. Make sure that Caps Lock is off when entering this information.The Ethernet port LEDs are off. If the Ethernet port LEDs do not light when the Ethernet connection is made, check the following:• Make sure that the Ethernet cable connections are secure at the modem router and computer.• Make sure that power is turned on to the connected modem or computer.Wireless LEDs are off. If the Wireless LEDs do not come on, verify that the Enable Wireless Router Radio check box is selected in the Advanced Wireless Settings screen. See “Advanced Wireless Settings” on page 2-15.Table 7-2. Troubleshooting with the LEDsSituation Recommended Action
RangeMax Dual Band Wireless-N Modem Router DGND3300 User ManualTroubleshooting 7-5v1.0, December 2008If the modem router does not save changes you have made in the modem router menu, check the following:• When entering configuration settings, be sure to click the Apply button before moving to another screen, 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.Cannot Access the InternetIf your Internet connection was working previously, it is possible that this is due to a problem at your ISP. If you can access your router but you are unable to access the Internet, you can check its configuration, and you can determine whether the router can obtain an IP address from your Internet Service Provider (ISP). Checking the ConfigurationTo check the router configuration to make sure that it is correct:1. Start your browser, and select an external site such as http://www.netgear.com.2. Access the main menu of the router at http://www.routerlogin.net.• Select Basic Settings to view the Basic Settings screen.• Select ADSL to view the settings for Multiplexing method, VPI, and VCI settings.• You can select Setup Wizard and allow the modem router to automatically detect your Internet connection. Checking the WAN IP AddressUnless your ISP provides a fixed IP address, your router must request an IP address from the ISP. You can determine whether the request was successful using the Router Status screen.To check the WAN IP address: 1. Start your browser, and select an external site such as http://www.netgear.com.Note: If you are installing the modem router and have not yet configured the Internet connection, see Chapter 1, “Configuring Your Internet Connection” or the Modem Router Setup Manual.
RangeMax Dual Band Wireless-N Modem Router DGND3300 User Manual7-6 Troubleshootingv1.0, December 20082. Access the main menu of the router at http://www.routerlogin.net.3. Under Maintenance, select Router Status.4. Check that an IP address is shown for the Internet port. If 0.0.0.0 is shown, your router has not obtained an IP address from your ISP.If your router cannot obtain an IP address from the ISP, you might need to force your cable or DSL modem to recognize your new router by restarting your network, as described in Table 7-1 on page 7-1.If your router is still unable to obtain an IP address from the ISP, the problem might be one of the following:• Your ISP might require a login program.Ask your ISP whether they require PPP over Ethernet (PPPoE) or some other type of login.• If your ISP requires a login, the login name and password might be set incorrectly.• Your ISP might check for your computer’s host name.Assign the computer host name of your ISP account as the account name in the Basic Settings screen.• 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.If your 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 router’s configuration, reboot your computer, and verify the DNS address as described in the online document you can access from “Preparing Your Network” in Appendix B. You can also configure your computer manually with DNS addresses, as explained in your operating system documentation.• Your computer might not have the router configured as its TCP/IP gateway.If your computer obtains its information from the router by DHCP, reboot the computer, and verify the gateway address as described in the online document you can access from “Preparing Your Network” in Appendix B.
RangeMax Dual Band Wireless-N Modem Router DGND3300 User ManualTroubleshooting 7-7v1.0, December 2008• You might be running login software that is no longer needed.If your ISP provided a program to log you in to the Internet (such as WinPoET), you no longer need to run that software after installing your modem router. You might need to go to Internet Explorer and select Tools > Internet Options, click the Connections tab, and select Never dial a connection.Troubleshooting a Network Using the Ping UtilityMost network 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 network by using the ping utility in your computer or workstation.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 running Windows PC:1. From the Windows toolbar, click the Start button, and then select Run.2. In the field provided, type ping followed by the IP address of the router, as in this example:ping www.routerlogin.net3. 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– For a wired connection, make sure the numbered Ethernet port LED is on for the port to which you are connected. If the LED is off, follow the instructions in Table 7-2 on page 7-3.
RangeMax Dual Band Wireless-N Modem Router DGND3300 User Manual7-8 Troubleshootingv1.0, December 2008– Check that the corresponding Link LEDs are on for your network interface card. If your router and computer are connected to a separate Ethernet switch, make sure the Link LEDs are on for the switch ports that are connected to your computer and router.• Wrong network configuration– Verify that the Ethernet card driver software and TCP/IP software are both installed and configured on your computer.– Verify that the IP address for your router and your computer 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 computer to a remote device. 1. From the Windows toolbar, click the Start button, and then select Run.2. In the Windows Run window, type:ping -n 10 <IP address>where <IP address> is the IP address of a remote device such as your ISP’s DNS server.If the path is functioning correctly, replies like those shown in the previous section are displayed. If you do not receive replies:• Check that your computer has the IP address of your router listed as the default gateway. If the IP configuration of your computer is assigned by DHCP, this information is not visible in your computer’s Network Control Panel. Verify that the IP address of the router is listed as the default gateway as described in the online document you can access from “Preparing Your Network” in Appendix B.• Check to see that the network address of your computer (the portion of the IP address specified by the subnet mask) 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 computer, 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 computers. 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 computer connected to that modem. If this is the case, you must configure your router to “clone” or “spoof” the MAC address from the authorized computer.

Cause: The router does not adjust for daylight savings time. In the E-mail screen, select the Adjust for Daylight Savings Time check box.Wireless ConnectivityTo add a wireless computer to an existing wireless network, you must set up its wireless card to match the modem router’s settings. You can use Push 'N' Connect (WPS) (“Connecting Additional Wireless Client Devices After WPS Setup” on page 2-14) if your computer supports it. You can also manually configure the computer’s wireless settings.When you install a NETGEAR wireless card in your computer, a Smart Wizard is installed that can provide helpful information about your wireless network. You can find this program in your Windows Program menu or as an icon in your system tray. Other wireless card manufacturers might include a similar program. If you have no specific wireless card setup program installed, you can use the basic setup utility in Windows by following these steps:1. Open the Windows Control Panel, and double-click Network Connections.2. In the LAN section, double-click Wireless Network Connection.Note: If you are installing the modem router and have not yet set up a wireless connection, see Chapter 2, “Safeguarding Your Network”or the Modem Router Setup Manual.
