2-1v1.0, September 2009Chapter 2Safeguarding Your NetworkThe Wireless-N 300 Router Model WNR2000v2 provides highly effective security features, which are covered in detail in this chapter. This chapter includes the following sections:•“Choosing Appropriate Wireless Security”•“Recording Basic Wireless Settings Setup Information” on page 2-5•“Changing Wireless Security Settings” on page 2-6•“Viewing Advanced Wireless Settings” on page 2-12•“Using Push 'N' Connect (Wi-Fi Protected Setup)” on page 2-13•“Restricting Wireless Access by MAC Address” on page 2-19•“Changing the Administrator Password” on page 2-21•“Backing Up Your Configuration” on page 2-22•“Understanding Your Firewall” on page 2-23Choosing Appropriate Wireless Security Unlike wired networks, wireless networks allow anyone with a compatible adapter to receive your wireless data transmissions well beyond your walls. Operating an unsecured wireless network creates an opportunity for outsiders to eavesdrop on your network traffic or to enter your network to access your computers and files. Indoors, computers can connect over 802.11g/n wireless networks at ranges of up to 300 feet. Such distances can allow for others outside your immediate area to access your network. Use the security features of your wireless equipment that are appropriate to your needs.The time it takes to establish a wireless connection can vary depending on both your security settings and router placement. Stronger security methods can entail a cost in terms of throughput, latency, battery consumption, and equipment compatibility. In choosing an appropriate security level, you can also consider the effort compared to the reward for a hacker to break into your network. As a minimum, however, NETGEAR recommends using WEP with Shared Key authentication. Do not run an unsecured wireless network unless it is your intention to provide free Internet access for the public.
NETGEAR Wireless-N 300 Router WNR2000v2 User Manual 2-2 Safeguarding Your Networkv1.0, September 2009WEP connections can take slightly longer to establish. Also, WEP, WPA-PSK, and WPA2-PSK encryption can consume more battery power on a notebook computer, and can cause significant performance degradation with a slow computer.To configure the wireless network, you can:•Manually specify your SSID and your wireless security settings. The WNR2000v2 router provides two screens for configuring the wireless settings: –Wireless Settings. You access these under Setup in the main menu (see “Viewing Basic Wireless Settings” on page 2-6).–Advanced Wireless Settings. You access these under Advanced in the main menu (see “Viewing Advanced Wireless Settings” on page 2-12).Note: NETGEAR recommends that you change the administration password of your router. Default passwords are well known, and an intruder can use your administrator access to read or disable your security settings. For information about how to change the administrator password, see “Changing the Administrator Password” on page 2-21.Figure 2-1WNR20001) Open system: easy but no security2) MAC access list: no data security3) WEP: security but some performance impact4) WPA-PSK: strong security5) WPA2-PSK: very strong securityWireless datasecurity optionsRange: up to 300 foot radiusNote: Use these with other features that enhance security (Table 2-2 on page 2-4).
NETGEAR Wireless-N 300 Router WNR2000v2 User Manual Safeguarding Your Network 2-3v1.0, September 2009•Use Wi-Fi Protected Setup (WPS) to automatically set the SSID and implement WPA/WPA2 security on both the router and the client device. If the clients in your network are WPS capable, you can use Wi-Fi Protected Setup (WPS) to automatically set the SSID and implement WPA/WPA2 security on both the router and the client device (see “Using Push 'N' Connect (Wi-Fi Protected Setup)” on page 2-13).Basic security options are listed in order of increasing effectiveness in Table 2-1. Other features that affect security are listed in Table 2-2 on page 2-4. For more details on wireless security methods, click the link to the online document “Wireless Networking Basics” in Appendix B.Table 2-1. Wireless Security OptionsSecurity Type DescriptionNone. No wireless security. Recommended only for troubleshooting wireless connectivity. Do not run an unsecured wireless network unless it is your intention to provide free Internet access for the public.WEP. Wired Equivalent Privacy. Wired Equivalent Privacy (WEP) data encryption provides moderate data security. WEP Shared Key authentication and WEP data encryption can be defeated by a determined eavesdropper using publicly available tools.For more information, see “Configuring WEP Wireless Security” on page 2-9.WPA-PSK (TKIP). WPA-PSK standard encryption with TKIP encryption type.WPA2-PSK (AES). Wi-Fi Protected Access version 2 with Pre-Shared Key; WPA2-PSK standard encryption with the AES encryption type.WPA-PSK (TKIP) + WPA2-PSK (AES). Mixed mode.Wi-Fi Protected Access with Pre-Shared Key (WPA-PSK and WPA2-PSK) data encryption provides extremely strong data security, very effectively blocking eavesdropping. Because WPA and WPA2 are relatively new standards, older wireless adapters and devices might not support them.For more information, see “Configuring WPA-PSK and WPA2-PSK Wireless Security” on page 2-10.
NETGEAR Wireless-N 300 Router WNR2000v2 User Manual 2-4 Safeguarding Your Networkv1.0, September 2009Table 2-2. Other Features That Enhance SecuritySecurity Type DescriptionDisable the wireless router radio. If you disable the wireless router radio, wireless devices cannot communicate with the router at all. You might disable this when you are away or when other users of your network all use wired connections.For more information, see “Viewing Advanced Wireless Settings” on page 2-12.Turn off the broadcast of the wireless network name SSID. If you disable the broadcast of the SSID, only devices that know the correct SSID can connect. This nullifies the wireless network discovery feature of some products such as Windows XP, but your data is still fully exposed to an intruder using available wireless eavesdropping tools.For more information, see “Viewing Advanced Wireless Settings” on page 2-12.Restrict access based on MAC address. You can restrict access to only trusted computers so that unknown computers cannot wirelessly connect to the WNR2000v2 router. MAC address filtering adds an obstacle against unwanted access to your network by the general public, but the data broadcast over the wireless link is fully exposed. This data includes your trusted MAC addresses, which can be read and impersonated by a hacker.For more information, see “Restricting Wireless Access by MAC Address” on page 2-19.Modify your firewall’s rules. By default, the firewall allows any outbound traffic and prohibits any inbound traffic except for responses to your outbound traffic. However, you can modify the firewall’s rules.For more information, see “Understanding Your Firewall” on page 2-23.Use the Push 'N' Connect feature (Wi-Fi Protected Setup). Wi-Fi Protected Setup provides easy setup by means of a push button. Older wireless adapters and devices might not support this. Check whether devices are WPS enabled.For more information, see “Using Push 'N' Connect (Wi-Fi Protected Setup)” on page 2-13.

NETGEAR Wireless-N 300 Router WNR2000v2 User Manual 2-8 Safeguarding Your Networkv1.0, September 2009•Channel. This field determines which operating frequency is used. It should not be necessary to change the wireless channel unless you notice interference problems with another nearby wireless network. The wireless router uses channel bonding technology to extend the bandwidth for data transmission. For more information about the wireless channel frequencies, see the online document that you can access from “Wireless Networking Basics” in Appendix B.•Mode. This field determines which data communications protocol is used. You can choose from:–Up To 54 Mbps. Legacy mode, for compatibility with the slower 802.11b and 802.11g wireless devices.–Up To 145 Mbps. Neighbor Friendly mode, for reduced interference with neighboring wireless networks. Provides two transmission streams with different data on the same channel at the same time, but also allows 802.11b and 802.11g wireless devices. This is the default mode.–Up To 300 Mbps. Performance mode, using channel expansion to achieve the 300 Mbps data rate. The WNR2000v2 router will use the channel you selected as the primary channel and expand to the secondary channel (primary channel +4 or –4) to achieve a 40 MHz frame-by-frame bandwidth. The WNR2000v2 router will detect channel usage and will disable frame-by-frame expansion if the expansion would result in interference with the data transmission of other access points or clients.•Security Options. The selection of wireless security options can significantly affect your network performance. The time it takes to establish a wireless connection can vary depending on both your security settings and router placement. WEP connections can take slightly longer to establish. Also, WEP, WPA-PSK, and WPA2-PSK encryption can consume more battery power on a notebook computer, and can cause significant performance degradation with a slow computer. Instructions for configuring the security options can be found in “Choosing Appropriate Wireless Security” on page 2-1. A full explanation of wireless security standards is available in the online document that you can access from “Wireless Networking Basics” in Appendix B.3. Click Apply to save your settings.Note: The maximum wireless signal rate is derived from the IEEE Standard 802.11 specifications. Actual data throughput will vary. Network conditions and environmental factors, including volume of network traffic, building materials and construction, and network overhead, lower actual data throughput rate.
NETGEAR Wireless-N 300 Router WNR2000v2 User Manual Safeguarding Your Network 2-9v1.0, September 2009Configuring WEP Wireless SecurityWEP Shared Key authentication and WEP data encryption can be defeated by a determined eavesdropper using publicly available tools.WEP offers the following options:•Automatic. With the Automatic option, the router will try both Open System and Shared Key authentication. Normally this setting is suitable. If it fails, select Open System or Shared Key. You can also refer to your wireless adapter’s documentation to see what method to use. •Open System. With Open System authentication and 64 or 128 bit WEP data encryption, the WNR2000v2 router does perform data encryption but does not perform any authentication. Anyone can join the network. This setting provides very little practical wireless security.•Shared Key. With Shared Key authentication, a wireless device must know the WEP key to join the network. Select the encryption strength (64 or 128 bit data encryption). Manually enter the key values, or enter a word or group of printable characters in the Passphrase field. Manually entered keys are not case-sensitive, but passphrase characters are case-sensitive.To configure WEP data encryption:1. Select Wireless Settings under Setup in the main menu.2.

Click Apply to save your settings.Configuring WPA-PSK and WPA2-PSK Wireless SecurityWi-Fi Protected Access with Pre-Shared Key (WPA-PSK and WPA2-PSK) data encryption provides extremely strong data security, very effectively blocking eavesdropping. Because WPA and WPA2 are relatively new standards, older wireless adapters and devices might not support them. Check whether newer drivers are available from the manufacturer. Also, you might be able to use the Push 'N' Connect feature to configure this type of security if it is supported by your wireless clients. See “Using Push 'N' Connect (Wi-Fi Protected Setup)” on page 2-13.Figure 2-3
NETGEAR Wireless-N 300 Router WNR2000v2 User Manual Safeguarding Your Network 2-11v1.0, September 2009WPA–Pre-Shared Key does perform authentication. WPA-PSK uses TKIP (Temporal Key Integrity Protocol) data encryption, and WPA2-PSK uses AES (Advanced Encryption Standard) data encryption. Both methods dynamically change the encryption keys making them nearly impossible to circumvent.Mixed mode allows clients using either WPA-PSK (TKIP) or WPA2-PSK (AES). This provides the most reliable security, and is easiest to implement, but it might not be compatible with older adapters.To configure WPA-PSK, WPA2-PSK, or WPA-PSK+WPA2-PSK:1. Select Wireless Settings under Setup in the main menu. The Wireless Settings screen displays.2. Select one of the WPA-PSK or WPA2-PSK options for the security type. The third option (WPA-PSK [TKIP] + WP2-PSK [AES]) is the most flexible, since it allows clients using either WPA-PSK or WPA2-PSK. 3. In the Passphrase field, enter a word or group of 8–63 printable characters. The passphrase is case-sensitive.Note: Not all wireless adapters support WPA. Furthermore, client software is also required. Windows XP with Service Pack 2 does include WPA support. Nevertheless, the wireless adapter hardware and driver must also support WPA. For instructions on configuring wireless computers or PDAs (personal digital assistants) for WPA-PSK security, consult the documentation for the product you are using.Figure 2-4

Log in to the router as described in “Logging In To Your Wireless Router” on page 1-2.2. Select Wireless Settings under Advanced in the main menu.These options are available under WPS Settings:•Router’s PIN. The PIN is displayed so that you can use it to configure the router through WPS (Wi-Fi Protected Setup). It is also displayed on the router’s label.•Disable Router’s PIN. If the router’s PIN is disabled, you cannot configure the router’s wireless settings with WPS. However, if your settings are already configured, you can still add WPS-enabled wireless clients. The router might disable the PIN if it detects suspicious attempts to break into your wireless settings; this can happen if the check box is selected. You can enable the PIN by clearing the check box and clicking Apply. •Keep Existing Wireless Settings. This check box is automatically selected after WPS is enabled to prevent unwanted settings changes, and is also selected if you have already specified wireless security settings or your SSID without using WPS. When this check box is not selected, adding a new wireless client using the push button or the Add WPS Client screen (see “Push Button Configuration” on page 2-14) changes the router’s SSID and security passphrase. You might need to clear it if you are using certain registrars, such as for a Windows Vista PC, to configure the router through WPS.Figure 2-10
NETGEAR Wireless-N 300 Router WNR2000v2 User Manual 2-18 Safeguarding Your Networkv1.0, September 2009Connecting Additional Wireless Client Devices after WPS SetupYou can add WPS-enabled and non-WPS-enabled client devices.Adding Additional WPS-Enabled ClientsTo add an additional wireless client device that is WPS enabled:1. Follow the procedures in “Push Button Configuration” on page 2-14 or “Security PIN Entry” on page 2-15.2. For information about how to view a list of all devices connected to your router (including wireless and Ethernet-connected), see “Viewing a List of Attached Devices” on page 6-7.Adding Additional Non-WPS-Enabled ClientsIf you are connecting a combination of WPS-enabled clients and clients that are not WPS enabled, you cannot use the WPS setup procedures to add clients that are not WPS enabled.To connect both non-WPS-enabled and WPS-enabled clients to the WNR2000v2 router:1. Configure the settings of the WNR2000v2 router (shown in the Wireless Settings screen) for WPA-PSK or WPA2-PSK security, and record that information. See “Configuring WPA-PSK and WPA2-PSK Wireless Security” on page 2-10.When you change security settings, all existing connected wireless clients that do not share those settings are disassociated and disconnected from the router.2. For the non-WPS-enabled devices that you wish to connect, open the networking utility, and follow the utility’s instructions to enter security settings.3. For the WPS-enabled devices that you wish to connect, follow the procedures in “Using Push 'N' Connect (Wi-Fi Protected Setup)” on page 2-13. The WNR2000v2 router automatically preserves the settings you configured in step 1 so all clients share the same security settings (for more information, see “Configuring the WPS Settings” on page 2-17).Note: Your wireless settings do not change when you add an additional WPS-enabled client unless you have cleared the Keep Existing Wireless Settings check box (in the Wireless Settings screen). If you do clear the check box, a new SSID and a passphrase are generated, and all existing connected wireless clients are disassociated and disconnected from the router.

For information about how to view a list of all devices connected to your router (including wireless and Ethernet connected), see “Viewing a List of Attached Devices” on page 6-7.Restricting Wireless Access by MAC AddressWhen a Wireless Card Access List is configured and enabled, the router checks the MAC address of any wireless device attempting a connection and allows only connections to computers identified on the trusted computers list. The Wireless Card Access List displays a list of wireless computers that you allow to connect to the router based on their MAC addresses. These wireless computers must also have the correct SSID and wireless security settings to access the wireless router.The MAC address is a network device’s unique 12-character physical address, containing the hexadecimal characters 0–9, a–f, or A–F only, and separated by colons (for example, 00:09:AB:CD:EF:01). It can usually be found on the bottom of the wireless card or network interface device. If you do not have access to the physical label, you can display the MAC address using the network configuration utilities of the computer. In WindowsXP, for example, typing the ipconfig/all command in an MSDOS command prompt window displays the MAC address as Physical Address. You might also find the MAC addresses in the router’s Attached Devices screen.To restrict access based on MAC addresses:1. Select Wireless Settings under Advanced in the main menu.2. In the Advanced Wireless Settings screen, click Setup Access List to display the Wireless Card Access List.Figure 2-11

Click Apply to save your Wireless Card Access List settings.Now, only devices on this list can wirelessly connect to the WNR2000v2 router.Changing the Administrator PasswordThe default password for the router’s Web Configuration Manager is password. NETGEAR recommends that you change this password to a more secure password. Note: When configuring the router from a wireless computer whose MAC address is not in the Trusted PC list, if you select Turn Access Control On, you lose your wireless connection when you click Apply. You must then access the wireless router from a wired computer or from a wireless computer that is on the access control list to make any further changes.Warning: MAC address filtering adds an obstacle against unwanted access to your network by the general public. However, because your trusted MAC addresses appear in your wireless transmissions, an intruder can read them and impersonate them. Do not rely on MAC address filtering alone to secure your network.Tip: Before changing the router password, back up your configuration settings with the default password of password. If you save the settings with a new password, and then you later forget the new password, you will have to reset the router back to the factory defaults, and log in using the default password of password. This means you will have to re-enter all the router configuration settings. For information about how to back up your settings, see “Backing Up and Restoring the Configuration” on page 6-8.
NETGEAR Wireless-N 300 Router WNR2000v2 User Manual 2-22 Safeguarding Your Networkv1.0, September 2009To change the administrator password:1. On the main menu, under Maintenance, select Set Password to display the Set Password screen.2. To change the password, first enter the old password, then enter the new password twice. 3. Click Apply.Backing Up Your ConfigurationThe configuration settings of the WNR2000v2 router are stored within the router in a configuration file. You can back up (save) this file and retrieve it later. NETGEAR recommends that you save your configuration file after you complete the configuration. If the router fails or becomes corrupted, or an administrator password is lost, you can easily re-create your configuration by restoring the configuration file.For instructions on saving and restoring your configuration file, see “Managing the Configuration File” on page 6-7.Figure 2-13Tip: Before saving your configuration file, change the administrator password to the default, password. Then change it again after you have saved the configuration file. If you save the file with a new password, and then you later forget the new password, you will have to reset the router back to the factory defaults and log in using the default password of password. This means you will have to re-enter all the router configuration settings.
NETGEAR Wireless-N 300 Router WNR2000v2 User Manual Safeguarding Your Network 2-23v1.0, September 2009Understanding Your FirewallYour Wireless-N 300 Router Model WNR2000v2 contains a true firewall to protect your network from attacks and intrusions. A firewall is a device that protects one network from another while allowing communication between the two. Using a process called Stateful Packet Inspection, the firewall analyzes all inbound and outbound traffic to determine whether or not it will be allowed to pass through.By default, the firewall allows any outbound traffic and prohibits any inbound traffic except for responses to your outbound traffic. However, you can modify the firewall’s rules to achieve the following behavior:•Blocking sites. Block access from your network to certain Web locations based on Web addresses and Web address keywords. This feature is described in “Blocking Access to Internet Sites” on page 3-1.•Blocking services. Block the use of certain Internet services by specific computers on your network. This feature is described in “Blocking Access to Internet Services” on page 3-3.•Scheduled blocking. Block sites and services according to a daily schedule. This feature is described in “Scheduling Blocking” on page 3-5.•Allow inbound access to your server. To allow inbound access to resources on your local network (for example, a Web server or remote desktop program), you can open the needed services by configuring port forwarding as described in “Allowing Inbound Connections to Your Network” on page 5-1.•Allow certain games and applications to function correctly. Some games and applications need to allow additional inbound traffic in order to function. Port triggering can dynamically allow additional service connections, as described in “Configuring Port Triggering” on page 5-10. Another feature to solve application conflicts with the firewall is Universal Plug and Play (UPnP), described in “Using Universal Plug and Play” on page 5-14.

NETGEAR Wireless-N 300 Router WNR2000v2 User Manual Restricting Access From Your Network 3-3v1.0, September 2009Since the trusted user is identified by IP address, you should configure that computer with a fixed IP address.5. Click Apply to save all your settings in the Block Sites screen.Blocking Access to Internet ServicesThe WNR2000v2 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.To block access to Internet services:1. Select Block Services under Content Filtering in the main menu. The Block Services screen displays.2. Enable service blocking by selecting either Per Schedule or Always, and then click Apply. To block by schedule, be sure to specify a time period in the Schedule screen. For information about scheduling, see “Scheduling Blocking” on page 3-5.Figure 3-2

NETGEAR Wireless-N 300 Router WNR2000v2 User Manual Customizing Your Network Settings 4-3v1.0, September 2009Configuring LAN TCP/IP Setup ParametersThese are advanced settings that you might configure if you are a network administrator and your network contains multiple routers. The router is shipped preconfigured to use private IP addresses on the LAN side and to act as a DHCP server (see “Using the Router as a DHCP Server” on page 4-4).The router’s default LAN IP configuration is:• LAN IP address. 192.168.1.1• Subnet mask. 255.255.255.0These addresses are part of the designated private address range for use in private networks and should be suitable for most applications. If your network has a requirement to use a different IP addressing scheme, you can make those changes in this screen.The LAN IP settings are:•IP Address. The LAN IP address of the router.•IP Subnet Mask. The LAN subnet mask of the 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 router.•RIP Direction. RIP allows a router to exchange routing information with other routers. The RIP Direction selection controls how the router sends and receives RIP packets. Both is the default. – When set to Both or In Only, the router incorporates the RIP information that it receives. – When set to Both or Out Only, the router broadcasts its routing table periodically. •RIP Version. This controls the format and the broadcasting method of the RIP packets sent by the router. (It recognizes both formats when receiving.) The default setting is Disabled. –RIP-1 is universally supported. RIP-1 is usually adequate unless you have an unusual network setup. –RIP-2B carries more information than RIP-1 and uses subnet broadcasting.–RIP-2M carries more information than RIP-1 and uses multicasting.Note: If you change the LAN IP address of the 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.
NETGEAR Wireless-N 300 Router WNR2000v2 User Manual 4-4 Customizing Your Network Settingsv1.0, September 2009Using the Router as a DHCP ServerBy default, the router functions as a DHCP server, allowing it to assign IP, DNS server, and default gateway addresses to all computers connected to the router’s LAN. The assigned default gateway address is the LAN address of the router. The 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.To specify a pool of IP addresses to be assigned, set the starting IP address and ending IP address. These addresses should be part of the same IP address subnet as the router’s LAN IP address. Using the default addressing scheme, you should define a range between 192.168.1.2 and 192.168.1.254, although you might wish to save part of the range for devices with fixed addresses.The 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 router’s LAN IP address)• Primary DNS server (if you entered a primary DNS address in the Basic Settings screen; otherwise, the router’s LAN IP address)• Secondary DNS server (if you entered a secondary DNS address in the Basic Settings screen)To use another device on your network as the DHCP server, or to manually specify 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 need to set your computers’ IP addresses manually or they will not be able to access the router.Note: For most applications, the default DHCP and TCP/IP settings of the 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.
NETGEAR Wireless-N 300 Router WNR2000v2 User Manual Customizing Your Network Settings 4-5v1.0, September 2009Using 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 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. 2. In the IP Address field, enter the IP address to assign to the computer or server. (Choose an IP address from the router’s LAN subnet, such as 192.168.1.x.) 3. Enter the MAC address of the computer or server.4. Click Apply to enter the reserved address into the table. To edit or delete a reserved address entry: 1. Click the button next to the reserved address you want to edit or delete. 2. Click Edit or Delete.Figure 4-2Tip: 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 router’s DHCP server. Reboot the computer or access its IP configuration and force a DHCP release and renew.
NETGEAR Wireless-N 300 Router WNR2000v2 User Manual 4-6 Customizing Your Network Settingsv1.0, September 2009Using 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 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 specify in the router. Then, whenever your ISP-assigned IP address changes, your 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 router at hostname.dyndns.org.Select Dynamic DNS under Advanced in the main menu. The Dynamic DNS screen displays.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.Figure 4-3
NETGEAR Wireless-N 300 Router WNR2000v2 User Manual Customizing Your Network Settings 4-7v1.0, September 2009To configure for a Dynamic DNS service: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. Enter the host name (or domain name) that your Dynamic DNS service provider gave you.5. Enter 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. Enter 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.
NETGEAR Wireless-N 300 Router WNR2000v2 User Manual 4-8 Customizing Your Network Settingsv1.0, September 2009Configuring the WAN Setup OptionsThe WAN Setup options let you configure a DMZ (demilitarized zone) server, change the Maximum Transmit Unit (MTU) size, and enable the wireless router to respond to a ping on the WAN (Internet) port. Select WAN Setup under Advanced in the main menu. The WAN Setup screen displays. Disabling the 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.Setting 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 router is programmed to recognize some of these applications and to work correctly with Figure 4-4
NETGEAR Wireless-N 300 Router WNR2000v2 User Manual Customizing Your Network Settings 4-9v1.0, September 2009them, 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 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. Select the Default DMZ Server check box.2. In the Default DMZ Server fields, enter the IP address for that computer or server.3. Click Apply.Responding to a Ping on the Internet (WAN) PortIf you want the router to respond to a ping from the Internet, select the Respond to Ping on Internet Port check box. This should be used only as a diagnostic tool, since it allows your router to be discovered by Internet scanners. Do not select this check box unless you have a specific reason to do so, such as when troubleshooting your connection.Setting the MTU SizeThe normal MTU value for most Ethernet networks is 1500 bytes, 1492 bytes for PPPoE connections, or 1450 for PPTP connections. For some ISPs, you might need to reduce the MTU size, but this is rarely required and should not be done unless you are sure it is necessary for your ISP connection. For more information, see “Changing the MTU Size” on page 5-16.To change the MTU size:1. In the MTU Size field, enter a new size between 64 and 1500.2. Click Apply to save the new configuration.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.
NETGEAR Wireless-N 300 Router WNR2000v2 User Manual 4-10 Customizing Your Network Settingsv1.0, September 2009Configuring NAT FilteringNetwork Address Translation (NAT) determines how the 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. For more information about NAT, see “How Your Computer Accesses a Remote Computer through Your Router” on page 5-2.To change the NAT option:1. In the NAT Filtering area, select either the Secured or the Open radio button.2. Click Apply to save the new configuration.Configuring Static RoutesStatic routes provide additional routing information to your router. Under usual 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.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 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 router forwards your request to the ISP. The ISP forwards your request to the company where you are employed, and the request is likely to be denied by the company’s firewall.In this case you must define a static route, telling your router that 134.177.0.0 should be accessed through the ISDN router at 192.168.1.100. 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.
NETGEAR Wireless-N 300 Router WNR2000v2 User Manual Customizing Your Network Settings 4-11v1.0, September 2009• 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.To add or edit a static route:1. Select Static Routes under Advanced in the main menu. The Static Routes screen displays.2. Click Add to expand the Static Routes screen.3. In the Route Name field, enter a name for this static route. (This is for identification purposes only.) 4. Select the Private check box if you want to limit access to the LAN only. If Private is selected, the static route is not reported in RIP. 5. Select the Active check box to make this route effective. Figure 4-5Figure 4-6

In the IP Subnet Mask field, enter the IP subnet mask for this destination.If the destination is a single host, enter 255.255.255.255. 8. In the Gateway IP Address field, enter the gateway IP address, which must be a router on the same LAN segment as the WNR2000v2 router. 9. In the Metric field, enter a number between 1 and 15 as the metric value. This represents the number of routers between your network and the destination. Usually, a setting of 2 or 3 works, but if this is a direct connection, set it to 1. 10. Click Apply to have the static route entered into the table.
5-1v1.0, September 2009Chapter 5Fine-Tuning Your NetworkThis chapter describes how to modify the configuration of the Wireless-N 300 Router Model WNR2000v2 to allow specific applications to access the Internet or to be accessed from the Internet, and how to make adjustments to enhance your network’s performance.This chapter includes the following sections:•“Allowing Inbound Connections to Your Network”•“Configuring Port Forwarding to Local Servers” on page 5-6•“Configuring Port Triggering” on page 5-10•“Using Universal Plug and Play” on page 5-14•“Optimizing Wireless Performance” on page 5-15•“Changing the MTU Size” on page 5-16•“Quality of Service” on page 5-18•“Overview of Home and Small Office Networking Technologies” on page 5-24Allowing Inbound Connections to Your NetworkBy default, the WNR2000v2 router blocks any inbound traffic from the Internet to your computers except for replies to your outbound traffic. However, you might need to create exceptions to this rule for the following purposes:• To allow remote computers on the Internet to access a server on your local network. • To allow certain applications and games to work correctly when their replies are not recognized by your router.Your router provides two features for creating these exceptions: port forwarding and port triggering. This section explains how a normal outbound connection works, followed by two examples explaining how port forwarding and port triggering operate and how they differ.
NETGEAR Wireless-N 300 Router WNR2000v2 User Manual 5-2 Fine-Tuning Your Networkv1.0, September 2009How Your Computer Accesses a Remote Computer through Your RouterWhen a computer on your network needs to access a computer on the Internet, your computer sends your router a message containing source and destination address and process information. Before forwarding your message to the remote computer, your router must modify the source information and must create and track the communication session so that replies can be routed back to your computer. Here is an example of normal outbound traffic and the resulting inbound responses:1. You open Internet Explorer, beginning a browser session on your computer. Invisible to you, your operating system assigns a service number (port number) to every communication process running on your computer. In this example, let’s say Windows assigns port number 5678 to this browser session. 2. You ask your browser to get a Web page from the Web server at www.example.com. Your computer composes a Web page request message with the following address andport information: • The source address is your computer’s IP address.• The source port number is 5678, the browser session. • The destination address is the IP address of www.example.com, which your computer finds by asking a DNS server.• The destination port number is 80, the standard port number for a Web server process.Your computer then sends this request message to your router.3. Your router creates an entry in its internal session table describing this communication session between your computer and the Web server at www.example.com. Before sending the Web page request message to www.example.com, your router stores the original information and then modifies the source information in the request message, performing Network Address Translation (NAT):• The source address is replaced with your router’s public IP address.This is necessary because your computer uses a private IP address that is not globally unique and cannot be used on the Internet.• The source port number is changed to a number chosen by the router, such as 33333. This is necessary because two computers could independently be using the same session number.Your router then sends this request message through the Internet to the Web server at www.example.com.
NETGEAR Wireless-N 300 Router WNR2000v2 User Manual Fine-Tuning Your Network 5-3v1.0, September 20094. The Web server at www.example.com composes a return message with the requested Web page data. The return message contains the following address and port information:• The source address is the IP address of www.example.com.• The source port number is 80, the standard port number for a Web server process.• The destination address is the public IP address of your router.• The destination port number is 33333.The Web server then sends this reply message to your router.5. Upon receiving the incoming message, your router checks its session table to determine whether there is an active session for port number 33333. Finding an active session, the router then modifies the message, restoring the original address information replaced by NAT. The message now contains the following address and port information: • The source address is the IP address of www.example.com.• The source port number is 80, the standard port number for a Web server process.• The destination address is your computer’s IP address.• The destination port number is 5678, the browser session that made the initial request.Your router then sends this reply message to your computer, which displays the Web page from www.example.com.6. When you finish your browser session, your router eventually senses a period of inactivity in the communications. Your router then removes the session information from its session table, and incoming traffic is no longer accepted on port number 33333.How Port Triggering Changes the Communication ProcessIn the preceding example, requests are sent to a remote computer by your router from a particular service port number, and replies from the remote computer to your router are directed to that port number. If the remote server sends a reply back to a different port number, your router will not recognize it and will discard it. However, some application servers (such as FTP and IRC servers) send replies back to multiple port numbers. Using the port triggering function of your router, you can tell the router to open additional incoming ports when a particular outgoing port originatesa session.An example is Internet Relay Chat (IRC). Your computer connects to an IRC server at destination port 6667. The IRC server not only responds to your originating source port, but also sends an “identify” message to your computer on port 113. Using port triggering, you can tell the router,
NETGEAR Wireless-N 300 Router WNR2000v2 User Manual 5-4 Fine-Tuning Your Networkv1.0, September 2009“When you initiate a session with destination port 6667, you must also allow incoming traffic on port 113 to reach the originating computer.” Using steps similar to the preceding example, the following sequence shows the effects of the port triggering rule you have defined:1. You open an IRC client program, beginning a chat session on your computer. 2. Your IRC client composes a request message to an IRC server using a destination port number of 6667, the standard port number for an IRC server process. Your computer then sends this request message to your router.3. Your router creates an entry in its internal session table describing this communication session between your computer and the IRC server. Your router stores the original information, performs Network Address Translation (NAT) on the source address and port, and sends this request message through the Internet to the IRC server. 4. Noting your port triggering rule, and having observed the destination port number of 6667, your router creates an additional session entry to send any incoming port 113 traffic to your computer. 5. The IRC server sends a return message to your router using the NAT-assigned source port (as in the previous example, let’s say port 33333) as the destination port. The IRC server also sends an “identify” message to your router with destination port 113.6. Upon receiving the incoming message to destination port 33333, your router checks its session table to determine whether there is an active session for port number 33333. Finding an active session, the router restores the original address information replaced by NAT and sends this reply message to your computer.7. Upon receiving the incoming message to destination port 113, your router checks its session table and learns that there is an active session for port 113, associated with your computer. The router replaces the message’s destination IP address with your computer’s IP address and forwards the message to your computer.8. When you finish your chat session, your router eventually senses a period of inactivity in the communications. The router then removes the session information from its session table, and incoming traffic is no longer accepted on port numbers 33333 or 113.To configure port triggering, you need to know which inbound ports the application needs. Also, you need to know the number of the outbound port that will trigger the opening of the inbound ports. You can usually determine this information by contacting the publisher of the application, or user groups or newsgroups.Note: Only one computer at a time can use the triggered application.
NETGEAR Wireless-N 300 Router WNR2000v2 User Manual Fine-Tuning Your Network 5-5v1.0, September 2009How Port Forwarding Changes the Communication ProcessIn both of the preceding examples, your computer initiates an application session with a server computer on the Internet. However, you might need to allow a client computer on the Internet to initiate a connection to a server computer on your network. Normally, your router ignores any inbound traffic that is not a response to your own outbound traffic. You can configure exceptions to this default rule by using the port forwarding feature. A typical application of port forwarding can be shown by reversing the client-server relationship from our previous Web server example. In this case, a remote computer’s browser needs to access a Web server running on a computer in your local network. Using port forwarding, you can tell the router, “When you receive incoming traffic on port 80 (the standard port number for a Web server process), forward it to the local computer at 192.168.1.123.” The following sequence shows the effects of the port forwarding rule you have defined:1. The user of a remote computer opens Internet Explorer and requests a Web page from www.example.com, which resolves to the public IP address of your router. The remote computer composes a Web page request message with the following destination information: • The destination address is the IP address of www.example.com, which is the address of your router.• The destination port number is 80, the standard port number for a Web server process.The remote computer then sends this request message through the Internet to your router.2. Your router receives the request message and looks in its rules table for any rules covering the disposition of incoming port 80 traffic. Your port forwarding rule specifies that incoming port 80 traffic should be forwarded to local IP address 192.168.1.123. Therefore, your router modifies the destination information in the request message:The destination address is replaced with 192.168.1.123.Your router then sends this request message to your local network.3. Your Web server at 192.168.1.123 receives the request and composes a return message with the requested Web page data. Your Web server then sends this reply message to your router.4. Your router performs Network Address Translation (NAT) on the source IP address, and sends this request message through the Internet to the remote computer, which displays the Web page from www.example.com.To configure port forwarding, you need to know which inbound ports the application needs. You usually can determine this information by contacting the publisher of the application or user groups or newsgroups.
NETGEAR Wireless-N 300 Router WNR2000v2 User Manual 5-6 Fine-Tuning Your Networkv1.0, September 2009How Port Forwarding Differs from Port TriggeringThe following points summarize the differences between port forwarding and port triggering:• Port triggering can be used by any computer on your network, although only one computer can use it at a time.• Port forwarding is configured for a single computer on your network.• Port triggering does not need to know the computer’s IP address in advance. The IP address is captured automatically.• Port forwarding requires that you specify the computer’s IP address during configuration, and the IP address must never change.• Port triggering requires specific outbound traffic to open the inbound ports, and the triggered ports are closed after a period of no activity.• Port forwarding is always active and does not need to be triggered.Configuring Port Forwarding to Local ServersUsing the port forwarding feature, you can allow certain types of incoming traffic to reach servers on your local network. For example, you might make a local Web server, FTP server, or game server visible and available to the Internet. Use the Port Forwarding screen to configure the router to forward specific incoming protocols to computers on your local network. In addition to servers for specific applications, you can also specify a default DMZ server to which all other incoming protocols are forwarded. The DMZ server is configured in the WAN Setup screen, as discussed in “Setting Up a Default DMZ Server” on page 4-8.Before starting, you need to determine which type of service, application, or game you will provide, and the local IP address of the computer that will provide the service. Be sure the computer’s IP address never changes.Tip: To ensure that your server computer always has the same IP address, use the reserved IP address feature of your WNR2000v2 router. See “Using Address Reservation” on page 4-5 for instructions on how to use reserved IP addresses.
NETGEAR Wireless-N 300 Router WNR2000v2 User Manual Fine-Tuning Your Network 5-7v1.0, September 2009To configure port forwarding to a local server:1. Select Port Forwarding/Port Triggering under Advanced in the main menu. The Port Forwarding/Port Triggering screen displays.2.

In the table, select the button next to the service name.2. Click Edit Service or Delete Service to make changes.3. Click Apply.Application Example: Making a Local Web Server PublicIf you host a Web server on your local network, you can use port forwarding to allow Web requests from anyone on the Internet to reach your Web server. To make a local Web server public:1. Assign your Web server either a fixed IP address or a dynamic IP address using DHCP address reservation, as explained in “Using Address Reservation” on page 4-5. In this example, your router will always give your Web server an IP address of 192.168.1.33. 2. In the Port Forwarding screen, configure the router to forward the HTTP service to the local address of your Web server at 192.168.1.33. HTTP (port 80) is the standard protocol for Web servers.3. (Optional) Register a host name with a Dynamic DNS service, and configure your router to use the name as described in “Using a Dynamic DNS Service” on page 4-6. To access your Web server from the Internet, a remote user must know the IP address that has been assigned by your ISP. However, if you use a Dynamic DNS service, the remote user can reach your server by a user-friendly Internet name, such as mynetgear.dyndns.org.Figure 5-3
NETGEAR Wireless-N 300 Router WNR2000v2 User Manual 5-10 Fine-Tuning Your Networkv1.0, September 2009Configuring Port TriggeringPort triggering is a dynamic extension of port forwarding that is useful in these cases:• More than one local computer needs port forwarding for the same application (but not simultaneously).• An application needs to open incoming ports that are different from the outgoing port.When port triggering is enabled, the router monitors outbound traffic looking for a specified outbound “trigger” port. When the router detects outbound traffic on that port, it remembers the IP address of the local computer that sent the data. The router then temporarily opens the specified incoming port or ports, and forwards incoming traffic on the triggered ports to the triggering computer. While port forwarding creates a static mapping of a port number or range to a single local computer, port triggering can dynamically open ports to any computer that needs them and can close the ports when they are no longer needed.To configure port triggering, you need to know which inbound ports the application needs. Also, you need to know the number of the outbound port that will trigger the opening of the inbound ports. You can usually determine this information by contacting the publisher of the application or user groups or newsgroups.To set up port triggering: 1. Select Port Forwarding/Port Triggering under Advanced in the main menu. The Forwarding/Port Triggering screen displays (see Figure 5-1 on page 5-7).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 also enable Universal Plug and Play (UPnP) according to the instructions in “Using Universal Plug and Play” on page 5-14.

The UPnP screen displays.2. The available settings and information displayed 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.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.Figure 5-7
NETGEAR Wireless-N 300 Router WNR2000v2 User Manual Fine-Tuning Your Network 5-15v1.0, September 2009•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.Optimizing 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. 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.
NETGEAR Wireless-N 300 Router WNR2000v2 User Manual 5-16 Fine-Tuning Your Networkv1.0, September 2009•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)• 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.
NETGEAR Wireless-N 300 Router WNR2000v2 User Manual Fine-Tuning Your Network 5-17v1.0, September 2009The 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 either the technical support of the ISP or of NETGEAR recommends changing the MTU size. These might require an MTU change:– A secure Web site that will not 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.If you suspect an MTU problem, a common solution is to change the MTU size to 1400. If you are willing to experiment, you can gradually reduce the MTU size from the maximum value of 1500 until the problem goes away. Table 5-1 describes common MTU sizes and applications.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.Table 5-1. 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.

In the MTU Size field, enter a new size between 64 and 1500.3. Click Apply to save the new configuration.Quality of ServiceQuality of Service (QoS) is an advanced feature that can be used to prioritize some types of traffic ahead of others. The WNR2000v2 router can provide QoS prioritization over the wireless link and on the Internet connection. Using WMM QoS for Wireless Multimedia ApplicationsThe WNR2000v2 router supports Wi-Fi Multimedia Quality of Service (WMM QoS) to prioritize wireless voice and video traffic over the wireless link. WMM QoS provides prioritization of wireless data packets from different applications based on four access categories: voice, video, best effort, and background. For an application to receive the benefits of WMM QoS, both it and the client running that application must be WMM enabled. Legacy applications that do not support WMM, and applications that do not require QoS, are assigned to the best effort category, which receives a lower priority than voice and video. You can give prioritized Internet access to the following types of traffic:• For specific applications• For specific online games• On individual Ethernet LAN ports of the router• From a specific device by MAC addressConfiguring QoS for Internet AccessTo specify prioritization of traffic, you must create a policy for the type of traffic and add the policy to the QoS Policy table in the QoS Setup screen. To create a QoS policy:

Your Internet connection speed is determined by your modem type, such as ADSL or cable modem, as well as the connection speed of the sites to which you connect, and general Internet traffic. ADSL and cable 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 or cable modem 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 Wireless-N 300 Router Model WNR2000v2 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 such as the WN511B for your computers. Although the RangeMax NEXT 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.
NETGEAR Wireless-N 300 Router WNR2000v2 User Manual Fine-Tuning Your Network 5-25v1.0, September 2009•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.

NETGEAR Wireless-N 300 Router WNR2000v2 User Manual 7-6 Troubleshootingv1.0, September 2009• If you are attempting to set up your NETGEAR router as an additional router behind an existing router in your network, consider replacing the existing router instead. NETGEAR does not support such a configuration.• If you are attempting to set up your NETGEAR router as a replacement for an ADSL gateway in your network, the router cannot perform many gateway services, for example, converting ADSL or Cable data into Ethernet networking information. NETGEAR does not support such a configuration. Checking the Internet Service ConnectionIf you can access your router, but your router is unable to access the Internet, review the topics in this section: •“Obtaining an Internet IP Address”•“Troubleshooting PPPoE”•“Troubleshooting Internet Browsing”Obtaining an Internet IP AddressIf your wireless router is unable to access the Internet, and your Internet light is amber, check the wireless router to see if it is able to get an Internet IP address from your service provider. Unless you have a static IP address, your wireless router automatically requests an IP address from your service provider. To check your wireless router’s Internet IP address: 1. Log in to the wireless router.2. Select Router Status, under Maintenance in the main menu, to check that an IP address is shown for the Internet Port. If 0.0.0.0 is shown, your wireless router has not obtained an IP address from your service provider.If your router is unable to obtain an IP address from the your service provider, the problem might be one of the following:
NETGEAR Wireless-N 300 Router WNR2000v2 User Manual Troubleshooting 7-7v1.0, September 2009• You might need to force your cable or DSL modem to recognize your new router by restarting your network, in the sequence described in the NETGEAR Wireless Router Setup Manual.• Your service provider might require a login. Ask your service provider whether they require a PPP over Ethernet (PPPoE) login (see “Troubleshooting PPPoE” on page 7-7).• You might have incorrectly set the service name, user name or password. Review your router’s Basic Settings screen.• Your service provider might check for your computer's host name. Assign the computer Host Name of your ISP account to the wireless router on the Basic Settings screen.• Your service provider might only allow one Ethernet MAC address to connect to the Internet, and check for your computer’s MAC address. If this is the case:– Inform your service provider that you have bought a new network device, and ask them to use the wireless router’s MAC address, or – Configure your router to spoof your computer’s MAC address. On the Basic Settings screen in the Router MAC Address section, select “Use this Computer’s MAC Address” and click Apply. Then restart your network in the correct sequence (see the NETGEAR Wireless Router Setup Manual for instructions).Troubleshooting PPPoEIf you are using PPPoE, try troubleshooting your Internet connection.To troubleshoot a PPPoE connection:1. Log in to the wireless router.2. Select Router Status under Maintenance on the main menu.3. Click Connection Status. If all of the steps indicate “OK,” then your PPPoE connection is up and working.If any of the steps indicate “Failed,” you can attempt to reconnect by clicking Connect. The wireless router will continue to attempt to connect indefinitely.If you cannot connect after several minutes, you might be using an incorrect service name, user name, or password. There also might be a provisioning problem with your ISP.Note: Unless you connect manually, the wireless router will not authenticate using PPPoE until data is transmitted to the network.
NETGEAR Wireless-N 300 Router WNR2000v2 User Manual 7-8 Troubleshootingv1.0, September 2009Troubleshooting Internet BrowsingIf your wireless router can obtain an IP address but your computer is unable to load any web pages from the Internet, check the following:•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 will provide the addresses of one or two DNS servers for your use. If you entered a DNS address during the wireless router’s configuration, restart your computer. Alternatively, you can configure your computer manually with a DNS address, as explained in the documentation for your computer.•Your computer might not have the wireless router configured as its default gateway. Reboot the computer and verify that the wireless router address (www.routerlogin.net) is listed by your computer as the default gateway address.•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 router. You might need to go to Internet Explorer and select Tools > Internet Options, click the Connections tab, and select Never dial a connection.If the wireless router does not save changes you have made in the browser interface, check the following:• When entering configuration settings, be sure to click Apply before moving to another screen or tab, or your changes could be lost. • Click Refresh or Reload in the Web browser. The changes might have occurred, but the Web browser might be caching the old configuration.Troubleshooting Your 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. Troubleshooting a network is made very easy by using the ping utility in your computer or workstation. This section includes:•“Testing the LAN Path to Your Router”•“Testing the Path from Your Computer to a Remote Device”
NETGEAR Wireless-N 300 Router WNR2000v2 User Manual Troubleshooting 7-9v1.0, September 2009Testing 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 Start, 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 that the numbered LAN port light is on for the port to which you are connected. If the light is off, follow the instructions in “Troubleshooting Basic Functions” on page 7-2.– Check that the appropriate LEDs are on for your network devices. If your router and computer are connected to a separate Ethernet switch, make sure that the link lights 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.
NETGEAR Wireless-N 300 Router WNR2000v2 User Manual 7-10 Troubleshootingv1.0, September 2009Testing 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 be 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. For more information, see “Using the Setup Manual” on page 1-1.Problems with Date and TimeSelect E-mail under Content Filtering in the main menu to display a screen that shows the current date and time of day. The WNR2000v2 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 the following:
NETGEAR Wireless-N 300 Router WNR2000v2 User Manual Troubleshooting 7-11v1.0, September 2009• Date shown is January 1, 2000.Cause: The router has not yet successfully reached a network time server.

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.•Windows basic setup utility. If you have no specific wireless card setup program installed, you can use the basic setup utility in Windows:– Open the Windows Control Panel, and double-click Network Connections.– In the LAN section, double-click Wireless Network Connection.2. Use the adapter’s setup program to scan for available wireless networks, looking for the network name (SSID) of NETGEAR, or your custom SSID if you have changed it. 3. If your wireless network appears and has good signal strength, configure and test with the simplest wireless connection possible.If your wireless network does not appear, check these conditions:• Is your router’s wireless radio enabled? See “Viewing Advanced Wireless Settings” on page 2-12.• Is your router’s SSID broadcast enabled? See “Viewing Advanced Wireless Settings” on page 2-12.• Is your router set to a wireless standard that is not supported by your wireless adapter? Check the Mode setting as described in “Viewing and Configuring Basic ISP Settings” on page 1-7.
NETGEAR Wireless-N 300 Router WNR2000v2 User Manual 7-12 Troubleshootingv1.0, September 2009If your wireless network appears, but the signal strength is weak, check these conditions:• Is your router too far from your adapter, or too close? Place the computer that has the adapter near the router, but at least 6 feet away, and see whether the signal strength improves.• Is your wireless signal obstructed by objects between the router and your adapter? See “Optimizing Wireless Performance” on page 5-15.Restoring the Default Configuration and PasswordThis section explains how to restore the factory default configuration settings that reset the router’s user name to admin, the password to password, and the IP address to 192.168.1.1.You can erase the current configuration and restore factory defaults in two ways:• Use the Erase function of the router. To use the Erase function, see “Erasing the Configuration” on page 6-9.• Use the restore factory settings button on the rear panel of the router. Use this method for cases when the administration password or IP address is not known.To use the restore settings button:1. Locate the restore factory settings button on the rear panel of the router.2. Use a sharp object such as a pen or a paper clip to press and hold the restore factory settings button for about 5 seconds, until the Power light begins to blink.3. Release the restore factory settings button, and wait for the router to restart, and for the Power light to stop blinking and become solid green.The factory default settings will be restored so that you can access the router from your Web browser using the factory defaults.If the wireless router fails to restart, or the Power light continues to blink or turns solid amber, the unit might be defective.
