Figure 1. Package contents

The modem router has status LEDs and buttons on the front.

You can use the LEDs to verify the status and connections. The following table lists and describes each LED and button on the front panel of the modem router.

The rear panel has the connections and button shown in the following figure.

The modem router lets you access your network anywhere within the operating range of your wireless network. However, the operating distance or range of your wireless connection can vary significantly depending on the physical placement of your modem router. For example, the thickness and number of walls the wireless signal passes through can limit the range.

Additionally, other wireless access points in and around your home might affect your modem router’s signal. Wireless access points are modem routers, repeaters, WiFi range extenders, or any other device that emits a wireless signal for network access.

Position your modem router according to the following guidelines:

• • • Place your modem router near the center of the area where your computers and other devices operate, and within line of sight to your wireless devices.
    • Make sure that the modem router is within reach of an AC power outlet and near Ethernet cables for wired computers.
    • Place the modem router in an elevated location, minimizing the number walls and ceilings between the modem router and your other devices.
    • Place the modem router away from electrical devices such as these:
      – Ceiling fans
      – Home security systems
      – Microwaves
      – Computers
      – Base of a cordless phone
      – 2.4 GHz cordless phone
    • Place the modem router away from large metal surfaces, large glass surfaces, and insulated walls such as these:
      – Solid metal doors
      – Aluminum studs
      – Fish tanks
      – Mirrors
      – Brick
      – Concrete

The most common way to cable your modem router is the simplest, without any other routers or gateways on the same network. You can also cable the modem router to another router or gateway and log in to the modem router to specify this setting.

The modem router comes configured to work as both a modem and a router. You can share your Internet connection without connecting the modem router to a router or gateway.

To cable your modem router:

1. 1. 1. Connect a coaxial cable.
         Use the coaxial cable that your cable company provides to connect the cable port on the modem router to a cable wall outlet or a line splitter.
         For XFINITY cable Internet service, Comcast XFINITY recommends connecting your modem router to a cable wall outlet.
      2. Connect the power adapter provided in the package to the modem router and plug the power adapter in to an electrical outlet.
      3. Press the Power On/Off button on the rear panel of the modem router.
         The Power LED lights green.
         You can log in to the modem router to view or change its settings.

If you want to cable the modem router to a router, then you must log in to the modem router and change its Router Mode setting. Changing this setting prevents certain network conflicts that can occur when two devices on the same network perform routing functions such as network address translation (NAT) and DHCP (assigning IP addresses to devices on the network). This turns the modem router into a bridged modem

To cable your modem router to a gateway or router:

1. 1. 1. Connect a coaxial cable.
         Use the coaxial cable that your cable company provides to connect the cable port on the modem router to a cable wall outlet or a line splitter.
         For XFINITY cable Internet service, Comcast XFINITY recommends connecting your modem router to a cable wall outlet.
      2. Connect the power adapter to the modem router and plug the power adapter into an electrical outlet.
         The Power LED lights green.
      3. On your computer or wireless device, find and select the WiFi network.
         The WiFi network name is on the product label.
      4. Join the WiFi network and enter the WiFi password.

The 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 a 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 device with the smallest MTU.

The best MTU setting for NETGEAR equipment is often the default value. In some situations, changing the value fixes one problem but causes another. Leave the MTU unchanged unless one of these situations occurs:

• • • You experience problems connecting to your ISP or other Internet services, and the technical support of either the ISP or NETGEAR recommends changing the MTU setting.
      These web-based applications might require an MTU change:
      – A secure website that does not open, or displays only part of a web page
      – Yahoo email
      – MSN portal
      – 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. For example, you might not be able to access certain websites, frames within websites, secure login pages, or FTP or POP servers.

  To change the MTU size:

1. 1. 1. Launch an Internet browser from a computer or wireless device that is connected to the network.
      2. Type http://www.routerlogin.net or http://www.routerlogin.com.
         A login window opens.
      3. Enter the modem router user name and password.
         The user name is admin. The default password is password. The user name and password are case-sensitive.
         The BASIC Home page displays.
      4. Select ADVANCED > Setup > WAN Setup.
         
      5. In the MTU Size field, enter a value from 64 to 1500.
      6. Click the Apply button.
         Your change is saved.
         If 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. The following table describes common MTU sizes and applications.

The following settings display:

• • • Disable IPv4 Firewall Protection. NETGEAR recommends that you leave this check box empty so that the firewall protects your modem router.
    • Disable Port Scan and DoS Protection. DoS protection protects your LAN against denial of service attacks such as Syn flood, Smurf Attack, Ping of Death, and many others. Select this check box only in special circumstances.
    • Default DMZ Server. This feature is disabled by default. It is sometimes helpful when you are playing online games or videoconferencing, but it makes the firewall security less effective. See Set Up a Default DMZ Server on page 38.
    • Respond to Ping on Internet Port. This feature allows your modem router to be discovered. Use this feature only as a diagnostic tool or if you have a specific reason.
    • MTU Size (in bytes). The normal MTU (maximum transmit unit) value for most Ethernet networks is 1500 bytes, or 1492 bytes for PPPoE connections. Change the
      MTU only if you are sure that it is necessary for your ISP connection. See Change the MTU Size on page 24.
    • Disable SIP ALG. Some VoIP applications do not work well with the SIP ALG.
      Selecting this check box to turn off the SIP ALG might help your VoIP devices to create or accept a call through the modem router.

5. Click the Apply button. Your changes are saved.

The 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 other applications might not function well. In some cases, one local computer can run the application correctly if the IP address for that computer is entered as the default DMZ server.

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.

The modem router usually detects and discards incoming traffic from the Internet that is not a response to one of your local computers or a service that you have configured in the Port Forwarding/Port Triggering page. Instead of discarding this traffic, you can have the modem router forward the traffic to one computer on your network. This computer is called the default DMZ server.

To set up a default DMZ server:

1. 1. 1. Launch an Internet browser from a computer or wireless device that is connected to the network.
      2. Type http://www.routerlogin.net or http://www.routerlogin.com.
         A login window opens.

The modem router is preconfigured to use private IP addresses on the LAN side and to act as a DHCP server. The modem router’s default LAN IP configuration is as follows:
• LAN IP address. 192.168.0.1
• Subnet mask. 255.255.255.0
These addresses are part of the designated private address range for use in private networks and are suitable for most applications. If your network requires a different IP addressing scheme, you can change these settings

You might want to change these settings if you need a specific IP subnet that one or more devices on the network uses, or if you have competing subnets with the same IP scheme.

To change the LAN TCP/IP settings:

1. 1. 1. Launch an Internet browser from a computer or wireless device that is connected to the network.
      2. Type http://www.routerlogin.net or http://www.routerlogin.com.
         A login window opens.

         Your changes are saved.
         If you changed the LAN IP address of the modem router, you are disconnected when this change takes effect.
      8. To reconnect, close your browser, relaunch it, and log in to the modem router

By default, the modem router acts as a Dynamic Host Configuration Protocol (DHCP) server. The modem router assigns IP, DNS server, and default gateway addresses to all computers connected to the LAN. The assigned default gateway address is the LAN address of the modem router.

These addresses must be part of the same IP address subnet as the modem router’s LAN IP address. Using the default addressing scheme, define a range between 192.168.0.2 and 192.168.0.254, although you can save part of the range for devices with fixed addresses.

To specify the pool of IP addresses that the modem router assigns:

1. 1. 1. Launch an Internet browser from a computer or wireless device that is connected to the network.
      2. Type http://www.routerlogin.net or http://www.routerlogin.com.
         A login window opens.
      3. Enter the user name and password.
         The user name is admin. The default password is password. The user name and password are case-sensitive.
         The BASIC Home page displays.
      4. Select ADVANCED > Setup > LAN Setup.
         
      5. Make sure that the Use Router as DHCP Server check box is selected.
      6. Specify the range of IP addresses that the modem router assigns:
         a. In the Starting IP Address field, type the lowest number in the range.
         This IP address must be in the same subnet as the modem router.
         b. In the Ending IP Address field, type the number at the end of the range of IP addresses.
         This IP address must be in the same subnet as the modem router.
      7. Click the Apply button.
         Your settings are saved.
         The modem router delivers the following parameters to any LAN device that requests DHCP:
         • An IP address from the range that you have defined
         • Subnet mask
         • Gateway IP address (the modem router’s LAN IP address)
         • DNS server IP address (the modem router’s LAN IP address)

By default, the modem router acts as a DHCP server. The modem router assigns IP, DNS server, and default gateway addresses to all computers connected to the LAN. The assigned default gateway address is the LAN address of the modem router.
You can use another device on your network as the DHCP server, or specify the network settings of all your computers.
  To disable the DHCP server feature in the modem router:

1. 1. 1. Launch an Internet browser from a computer or wireless device that is connected to the network.
      2. Type http://www.routerlogin.net or http://www.routerlogin.com.

Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers, access the network and connect to other devices as needed. UPnP devices can automatically discover the services from other registered UPnP devices on the network.

If you use applications such as multiplayer gaming, peer-to-peer connections, or real-time communications such as instant messaging or remote assistance (a feature in Windows XP), enable UPnP.

To enable Universal Plug and Play:

1. 1. 1. Launch an Internet browser from a computer or wireless device that is connected to the network.
      2. Type http://www.routerlogin.net or http://www.routerlogin.com.
         A login window opens.
      3. Enter the user name and password.

      4. Select ADVANCED > Advanced Setup > UPnP.
         The UPnP page displays.
      5. Select the Turn UPnP On check box.
         By default, this check box is selected. UPnP for automatic device configuration can be enabled or disabled. If the Turn UPnP On check box is cleared, the modem router does not allow any device to automatically control modem router resources, such as port forwarding.
      6. Type the advertisement period in minutes.
         The advertisement period specifies how often the modem 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 more network traffic. Longer durations can compromise the freshness of the device status, but can significantly reduce network traffic.
      7. Type the advertisement time to live in hops.
         The time to live for the advertisement is measured in hops (steps) for each UPnP packet sent. Hops are the steps a packet takes between routers. 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, it might be necessary to increase this value.
      8. Click the Apply button.
         The UPnP Portmap Table displays the IP address of each UPnP device that is accessing the modem router and which ports (internal and external) that device has opened. The UPnP Portmap Table also displays what type of port is open and whether that port is still active for each IP address.
         To refresh the information in the UPnP Portmap table, click the Refresh button.

      8. To change the wireless channel, select a number in the Channel list.
         In some regions, not all channels are available. Do not change the channel unless you experience interference (shown by lost connections or slow data transfers). If this happens, experiment with different channels to see which is the best.When you use multiple access points, it is better if adjacent access points use different channels to reduce interference. The recommended channel spacing between adjacent access points is four channels (for example, use Channels 1 and 5, or 6 and 10).
      9. To change the mode, select it from the Mode list.
         For 2.4 GHz, Up to 600 Mbps is the default setting. The other settings are Up to 289 Mbps and Up to 54 Mbps.At 5 GHz, Up to 1300 Mbps is the default setting, which allows 802.11ac and 802.11a wireless devices to join the network. The other settings are Up to 600 Mbps and Up to 289 Mbps.
      10. Click the Apply button.

Internet service providers (ISPs) assign numbers called IP addresses to identify each Internet account. Most ISPs use dynamically assigned IP addresses. This means that the IP address can change at any time. You can use the IP address to access your network remotely, but most people don’t know what their IP addresses are or when this number changes.

To make it easier to connect, you can get a free account with a Dynamic DNS service that lets you use a domain name to access your home network. To use this account, you must set up the modem router to use Dynamic DNS. Then the modem router notifies the Dynamic DNS service provider whenever its IP address changes. When you access your Dynamic DNS account, the service finds the current IP address of your home network and automatically connects you.

If your ISP assigns a private WAN IP address (such as 192.168.x.x or 10.x.x.x), the Dynamic DNS service does not work because private addresses are not routed on the Internet.

To set up Dynamic DNS in the modem router:

1. 1. 1. Launch an Internet browser from a computer or wireless device that is connected to the network.
      2. Type http://www.routerlogin.net or http://www.routerlogin.com.

You can use port forwarding and port triggering to set up rules for Internet traffic. You need networking knowledge to set up these features.
This chapter includes the following sections:

• • • Set Up Port Forwarding to a Local Server
    • Set Up Port Triggering

If you have a server in your home network, you can allow certain types of incoming traffic to reach the server. For example, you might want to make a local web server, FTP server, or game server visible and available to the Internet.

The modem router can forward incoming traffic with specific protocols to computers on your local network. You can specify the servers for applications and you can also specify a default DMZ server to which the modem router forwards all other incoming protocols.

To forward specific incoming protocols:

1. 1. 1. Decide which type of service, application, or game you want to provide.
      2. Find the local IP address of the computer on your network that will provide the service.
         The server computer must always have the same IP address. To specify this setting, use the reserved IP address feature. See Reserve LAN IP Addresses on page 42.
      3. Launch an Internet browser from a computer or wireless device that is connected to the network.
      4. Type http://www.routerlogin.net or http://www.routerlogin.com.
         A login window opens.
      5. Enter the user name and password.
         The user name is admin. The default password is password. The user name and password are case-sensitive.

If 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. 1. 1. Assign your web server either a fixed IP address or a dynamic IP address using DHCP address reservation.
         In this example, your modem router always gives your web server an IP address of 192.168.0.33.
      2. In the Port Forwarding/Port Triggering page, configure the modem router to forward the
         HTTP service to the local address of your web server at 192.168.0.33.
         HTTP (port 80) is the standard protocol for web servers.
      3. (Optional) Register a host name with a Dynamic DNS service, and specify that name in the
         Dynamic DNS page of the modem router.
         Dynamic DNS makes it much easier to access a server from the Internet because you can type the name in the Internet browser. Otherwise, you must know the IP address that the ISP assigned, which typically changes.

The following sequence shows the effects of a port forwarding rule:

1. 1. 1. When you type the URL www.example.com in your browser, the browser sends a web page request message with the following destination information:
         • Destination address. The IP address of www.example.com, which is the address of your modem router.
         • Destination port number. 80, which is the standard port number for a web server process.
      2. Your modem router receives the message and finds your port forwarding rule for incoming port 80 traffic.
      3. The modem router changes the destination in the message to IP address 192.168.0.123 and sends the message to that computer.
      4. Your web server at IP address 192.168.0.123 receives the request and sends a reply message to your modem router.
      5. Your modem router performs Network Address Translation (NAT) on the source IP address, and sends the reply through the Internet to the computer or wireless device that sent the web page request.

Port triggering is a dynamic extension of port forwarding that is useful in these cases:
• An application must use port forwarding to more than one local computer (but not simultaneously).
• An application must open incoming ports that are different from the outgoing port.

With port triggering, the modem router monitors traffic to the Internet from an outbound “trigger” port that you specify. For outbound traffic from that port, the modem router saves the IP address of the computer that sent the traffic. The modem router temporarily opens the incoming port or ports that you specify in your rule, and forwards that incoming traffic to that destination.

Port forwarding creates a static mapping of a port number or range of ports to a single local computer. Port triggering can dynamically open ports to any computer when needed and close the ports when they are no longer needed.
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), enable Universal Plug and Play (UPnP).

To add a port triggering service:

1. 1. 1. Launch an Internet browser from a computer or wireless device that is connected to the network.
      2. Type http://www.routerlogin.net or http://www.routerlogin.com.
         A login window opens.
      3. Enter the user name and password.
         The user name is admin. The default password is password. The user name and password are case-sensitive.
         The BASIC Home page displays.
      4. Select ADVANCED > Advanced Setup > Port Forwarding/Port Triggering.
      5. Select the Port Triggering radio button.
      6. Click the Add Service button.
         
      7. In the Service Name field, type a descriptive service name.
      8. In the Service User list, select Any, or select Single address and enter the IP address of one computer:
         • Any (the default) allows any computer on the Internet to use this service.
         • Single address restricts the service to a particular computer.
      9. Select the service type, either TCP or UDP or TCP/UDP (both).
         If you are not sure, select TCP/UDP.
      10. In the Triggering Port field, enter the number of the outbound traffic port that will open the inbound ports.
      11. Enter the inbound connection port information in the Connection Type, Starting Port, and Ending Port fields.
      12. Click the Apply button.
          The service is now in the Portmap table. You must enable port triggering before the modem router used port triggering for the service that you added. See the following section.

Some application servers, such as FTP and IRC servers, send replies to multiple port numbers. Using port triggering, you can tell the modem router to open more incoming ports when a particular outgoing port starts a 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 modem router, “When you initiate a session with destination port 6667, you must also allow incoming traffic on port 113 to reach the originating computer.” The following sequence shows the effects of the port triggering rule you have defined:

1. 1. 1. You open an IRC client program to start 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 modem router.
      3. Your modem router creates an entry in its internal session table describing this communication session between your computer and the IRC server. Your modem 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 observing the destination port number of 6667, your modem router creates another session entry to send any incoming port 113 traffic to your computer.
      5. The IRC server sends a return message to your modem router using the NAT-assigned source port (for example, port 33333) as the destination port. The IRC server also sends an “identify” message to your modem router with destination port 113.
      6. When your modem router receives the incoming message to destination port 33333, it checks its session table to see if a session is active for port number 33333. Finding an active session, the modem router restores the original address information replaced by NAT and sends this reply message to your computer.
      7. When your modem router receives the incoming message to destination port 113, it checks its session table and finds an active session for port 113 associated with your computer. The modem 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 modem router eventually senses a period of inactivity in the communications. The modem router then removes the session information from its session table, and incoming traffic is no longer accepted on port numbers 33333 or 113.

This chapter provides information to help you diagnose and solve problems you might have with your modem router. If you do not find the solution here, check the NETGEAR support site at http://support.netgear.com for product and contact information.
This chapter contains the following sections:

• • • Troubleshoot with the LEDs
    • Cannot Log In to the Modem Router
    • Changes Not Saved
    • Wireless Connectivity
    • Troubleshoot Your Network Using the Ping Utility

You can use the LEDs on the front panel of the modem router for troubleshooting.

• • • Make sure that the power adapter is securely connected to your modem router and securely connected to a working power outlet.
    • Check that you are using the power adapter that NETGEAR supplied for this product.
    • If the problem persists, contact technical support for help at www.netgear.com/support.

When the modem router is turned on, the LEDs light for about 10 seconds and then turn off. If all the LEDs stay on, this indicates a fault within the modem router.
If all LEDs are still lit one minute after power-up, do the following:

• • • Cycle the power to see if the modem router recovers.
    • Press and hold the Reset button to return the modem router to its factory settings. For more information, see Factory Settings on page 88.
      If the error persists, you might have a hardware problem. Contact technical support at www.netgear.com/support.

If the Internet LED is off and the modem router is connected to the cable television cable, try the following:

• • • Make sure that the coaxial cable connections are secure at the modem router and at the wall jack.
    • Make sure that your cable Internet provider-provisioned your cable Internet service. Your provider can verify that the signal quality is good enough for modem router service.
    • Remove any excessive splitters that on your cable line. Run a “home run” back to the point where the cable enters your home.

When your modem router cannot access the Internet and your Internet LED is on, register the cable MAC address or device MAC address of your modem router with your cable Internet provider.

Additionally, check the setting for your computer’s TCP/IP gateway. It should be set to use the modem router. modem router. If your computer obtains its information from the modem router by DHCP, reboot the computer and verify the gateway address.

1. 1. 1. If you are unable to log in to the modem router from a computer or WiFi device on your local network, check the following:
         Make sure that you are connected to the modem router’s wired or WiFi network.
         • For a wired Ethernet connection, make sure that the Ethernet connection is secure and the modem router is powered on (its Power LED is lit).
         • For a WiFi connection, make sure that you selected the correct network. If you cannot find the WiFi network, make sure that the modem router is powered on (it’s Power LED is lit). If the modem router is powered on, someone might have turned off the SSID broadcast or the turned off the wireless radios. See Wireless Connectivity on page  84.
      2. If you are connected to the modem router network, but the web browser does not display the login window, check the following:
         • Make sure that your browser has Java, JavaScript, or ActiveX enabled. If you are using Internet Explorer, click the Refresh button to be sure that the Java applet is loaded.
         • Try quitting the browser and launching it again.
      3. If the browser displays the login window, but you cannot access the modem router, make sure that you are using the correct login information.
         The user name is admin, and the default password is password. Both are case-sensitive. Make sure that Caps Lock is off when you enter this information.
      4. If you customized advanced home network settings such as the IP address scheme, check the following:
         • Make sure that the IP address of your computer is on the same subnet as the modem router. If you are using the recommended addressing scheme, your computer’s address is in the range of 192.168.0.2 to 192.168.0.254.
         • If your computer’s IP address is shown as 169.254.x.x, recent versions of Windows and Mac OS 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 modem router, and reboot your computer.
         • If your modem router’s IP address was changed and you do not know the current IP address, clear the modem router’s configuration to factory defaults. This sets the modem router’s IP address to 192.168.0.1. For more information, see Factory Settings on page 88.

If the modem router does not save the changes you make in the modem router interface, check the following:

• • • When entering configuration settings, always click the Apply button before moving to another page or tab, or your changes are lost.
    • Click the Refresh or Reload button in the web browser. The changes might have occurred, but the old settings might be in the web browser’s cache.

If you are having trouble connecting wirelessly to the modem router, try to isolate the problem:

• • • The computer or WiFi device that you are using does not find the WiFi network.
      This can happen for the following reasons:
      – Someone pressed the WiFi On/Off button on the modem router, which turned off the wireless radios.
      Check the 2.4 GHz and 5 GHz LEDs on the front of the modem router. If they are off, press the WiFi On/Off button to turn the wireless radios back on.
      – Someone logged in to the modem router and disabled its wireless radios or set up a wireless schedule.
      In this case, pressing the WiFi On/Off button does not turn the wireless radios back on. You must log in to enable the wireless radios. Use an Ethernet cable to for a wired connection to the modem router. Then log in and change the settings. For more information, see Control the Wireless Radios on page 50.
      – Someone logged in to the modem router and disabled its SSID broadcast. Your wireless network is hidden and does not display in your wireless client’s scanning list. (By default, SSID broadcast is enabled.)
      To connect with WiFi, you must type the network SSID and password. For information about how to enable the SSID broadcast, see Specify Basic WiFi Settings on page 45.
    • You can find the WiFi network, but you can’t connect. Check the following:
      – Make sure that your computer or WiFi device supports the security that you are using for your wireless network (WPA or WPA2)?
      – You are not sure what the WiFi password is.
      The preset WiFi password is on the product label. If you changed it and do not remember the new password, you can use a wired Ethernet connection to log in to the modem router and view or change the WiFi password. For more information, see Change the WiFi Security Option on page 47
      – The WiFi signal strength is weak in your location:
      Is your modem router too far from your computer, or too close? Place your computer near the modem router, but at least 6 feet (1.8 meters) away, and see if the signal strength improves.
      Check for sources of WiFi interference that might block the signal. See Position Your Modem Router on page 9.

Most 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 using the ping utility in your computer or workstation.

You can ping the modem router from your computer to verify that the LAN path to your modem router is set up correctly.
To ping the modem router from a Windows computer:

1. 1. 1. From the Windows toolbar, click Start and select Run.
      2. In the field provided, type ping followed by the IP address of the modem router, as in this example: ping www.routerlogin.net
      3. Click the OK button.
         You should see a message like this one:
         Pinging <IP address > with 32 bytes of data
         If the path is working, you see this message:
         Reply from < IP address >: bytes=32 time=NN ms TTL=xxx
         If the path is not working, you see this message:
         Request timed out
         If the path is not functioning correctly, you might have one of the following problems:
         • Wrong physical connections
         For a wired connection, make sure that the numbered LAN port LED is lit for the port to which you are connected.
         Check that the appropriate LEDs are on for your network devices. If your modem router and computer are connected to a separate Ethernet switch, make sure that the link LEDs are lit for the switch ports that are connected to your computer and modem 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 modem router and your computer are correct and that the addresses are on the same subnet.

After verifying that the LAN path works correctly, test the path from your computer to a remote device.

1. 1. 1. From the Windows toolbar, click the Start button and 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 DNS server.
         If the path is functioning correctly, messages like those shown in the previous section display.
         If you do not receive replies, check the following:
         • Check that your computer has the IP address of your modem router listed as the default gateway. If DHCP assigns the IP configuration of your computers, this information is not visible in your computer Network Control Panel. Verify that the IP address of the modem router is listed as the default gateway.
         • 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 Internet Setup page.
         • Your ISP might 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. Some ISPs additionally restrict access to the MAC address of a single computer connected to that modem. If so, configure your modem router to “clone” or “spoof” the MAC address from the authorized computer.

This appendix covers the following topics:
• Factory Settings
• Technical Specifications

You can return the modem router to its factory settings. Use the end of a paper clip or a similar object to press and hold the Reset button on the back of the modem router for at least seven seconds. The modem router resets, and returns to the factory configuration settings shown in the following table.

1. Maximum wireless signal rate derived from IEEE Standard 802.11 specifications. Actual throughput can vary. Network conditions and environmental factors, including volume of network traffic, building materials and construction, and network overhead, lower actual data throughput rate.
