2.Under Allow Remote Access By, specify what external IP addresses will be allowed to access 
the router’s remote management.
• To allow access from any IP address on the Internet, select Everyone. 
• To allow access from a range of IP addresses on the Internet, select IP Address Range.
Enter a beginning and ending IP address to define the allowed range. 
• To allow access from a single IP address on the Internet, select Only This Computer.
Enter the IP address that will be allowed access. 
3.Specify the port number for accessing the management interface.
Normal Web browser access uses the standard HTTP service port 80. For greater security, 
enter a custom port number for the remote management Web interface. Choose a number 
between 1024 and 65535, but do not use the number of any common service port. The default 
is 8080, which is a common alternate for HTTP.
4.Click Apply to have your changes take effect.
Note: For enhanced security, restrict access to as few external IP addresses
as practical.
Note: When accessing your router from the Internet, type your router’s WAN IP address 
into your browser’s address or location field, followed by a colon (:) and the 
custom port number. For example, if your external address is 134.177.0.123 and 
you use port number 8080, then enter http://134.177.0.123:8080 in your browser.

4.Turn on the wireless router and wait 1 minute.
5.Turn on the computers. 
Make sure that the Ethernet cables are securely plugged in.
• The Internet status light on the wireless router is on if the Ethernet cable connecting the 
wireless router and the modem is plugged in securely and the modem and wireless router are 
turned on. 
• For each powered-on computer connected to the wireless router by an Ethernet cable, the 
corresponding numbered router LAN port light is on. 
Make sure that the wireless settings in the computer and router match exactly.
• For a wirelessly connected computer, the wireless network name (SSID) and WEP or WPA 
security settings of the router and wireless computer must match exactly. 
• If you have enabled the wireless router to restrict wireless access by MAC address, you must 
add the wireless computer’s MAC address to the router’s wireless card access list.
Make sure that the network settings of the computer are correct.
• Wired and wirelessly connected computers must have network (IP) addresses on the same 
network as the router. The simplest way to do this is to configure each computer to obtain an 
IP address automatically using DHCP. Click the link to the online document “Preparing Your 
Network” in Appendix B, or see the documentation that came with your computer.
• Some cable modem service providers require you to use the MAC address of the computer 
initially registered on the account. Your wireless router can capture and use that MAC address, 
as described in “Configuring Your Internet Connection Using the Smart Setup Wizard” on 
page 1-1. 
Check the Test light to verify correct router operation.
If the Test light does not turn off within 2 minutes after you turn the router on, reset the router 
according to the instructions in “Restoring the Default Configuration and Password” on page 7-13.

Troubleshooting Basic Functions
After you turn on power to the router, the following sequence of events should occur:
1.When power is first applied, verify that the Power light  is on.
2.After approximately 10 seconds, verify that:
a.The Power light is solidly on.
b.The Internet light is on.
c.A numbered LAN port light is on for any local port that is connected to a computer. This 
indicates that a link has been established to the connected device.
If any of the above conditions does not occur, see the appropriate following section.
The Power light is not on or is blinking.
If the Power and other lights are off when your router is turned on:
• Make sure that the power cord is properly connected to your router and that the power adapter 
is properly connected to a functioning power outlet. 
• Check that you are using the 12V DC 1A power adapter that NETGEAR supplied for this 
product.
• If the Power light blinks alternately green and amber every second, the router software is 
corrupted. This can happen if a firmware upgrade is interrupted, or if the router detects a 
problem with the firmware. For recovery instructions, contact Technical Support at 
www.netgear.com/support.
If the error persists, you have a hardware problem and should contact Technical Support at 
www.netgear.com/support.
The lights never turn off.
When the router is turned on, the lights turn on for about 10 seconds and then turn off. If all the 
lights stay on, there is a fault within the router.
If all lights are still on 1 minute after power-up:
• Cycle the power to see if the router recovers.
• Clear the router’s configuration to factory defaults as explained in “Restoring the Default 
Configuration and Password” on page 7-13.

If the error persists, you might have a hardware problem and should contact Technical Support at 
www.netgear.com/support.
The Internet or Ethernet port lights are not on.
If either the Ethernet port lights or the Internet light does not come on when the Ethernet 
connection is made, check the following:
• Make sure that the Ethernet cable connections are secure at the router and at the modem or 
computer.
• Make sure that power is turned on to the connected modem or computer.
• Make sure that you are using the correct cable:
When connecting the router’s Internet port to a cable or DSL modem, use the cable that was 
supplied with the cable or DSL modem. This cable could be a standard straight-through 
Ethernet cable or an Ethernet crossover cable.
The Wireless light is not on.
If the Wireless light does not come on, verify that the wireless feature is turned on according to the 
instructions in “Viewing Advanced Wireless Settings” on page 2-10.
Troubleshooting the Web Configuration Interface
If you are unable to access the router’s Web Configuration Interface from a computer on your local 
network, check the following:
• If you are connecting from a wireless computer, try connecting from a wired computer.
• Check the Ethernet connection between the wired computer and the router as described in 
“Troubleshooting Basic Functions” on page 7-3.
• Make sure that your computer’s IP address is on the same subnet as the router. For 
instructions, click the link to the online document “Preparing Your Network” in Appendix B to 
configure your computer.
Note: If your computer’s IP address is shown as 169.254.x.x: Windows and Mac OS 
generate and assign an IP address if the computer cannot reach a DHCP server. 
These autogenerated addresses are in subnet 169.254.x.x. If your IP address is 
in this range, check the connection from the computer to the router, and reboot 
your computer.

• Make sure that your browser has Java, JavaScript, or ActiveX enabled. If you are using 
Internet Explorer, click Refresh to be sure that the Java applet is loaded.
• Try closing the browser and opening it again, or try a different browser.
• Make sure that you are using the correct login information. The factory default login name is 
admin, and the password is password. Make sure that Caps Lock is off when entering this 
information.
If the router does not save changes you have made in the Web Configuration Interface, check the 
following:
• When entering configuration settings, be sure to click 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 the Internet Connection
If you can access your router but you are unable to access the Internet, you should first determine 
whether the router can obtain an IP address from your Internet Service Provider (ISP). Unless your 
ISP provides a static IP address, your router must request an IP address from the ISP. You can 
determine whether the request was successful using the Web Configuration Manager.
To check the WAN IP address: 
1.Start your browser, and select an external site such as http://www.netgear.com.
2.Access the main menu of the router’s configuration at http://www.routerlogin.net.
3.Under Maintenance, select Router Status.
4.Check that an IP address is shown for the Internet port. If 0.0.0.0 is shown, your router has not 
obtained an IP address from your ISP.
If your router is unable to obtain an IP address from the ISP, you might need to force your cable or 
DSL modem to recognize your new router by restarting your network, as described in “Be sure to 
restart your network in this sequence.” on page 7-1.
If your router is still unable to obtain an IP address from the ISP, the problem might be one of the 
following:
• Your ISP might require a login program.
Ask your ISP whether they require PPP over Ethernet (PPPoE) or some other type of login.

7-6Troubleshooting
v1.1, May 2008
• If your ISP requires a login, the login name or password might be set incorrectly.
• Your ISP might check for your computer’s host name.
Assign the computer host name of your ISP account as the account name in the Basic Settings 
screen.
• Your ISP allows only one Ethernet MAC address to connect to Internet and might check for 
your computer’s MAC address. In this case, do one of the following:
– Inform your ISP that you have bought a new network device, and ask them to use the 
router’s MAC address.
– Configure your router to spoof your computer’s MAC address. This procedure is 
explained in “Configuring Your Internet Connection Using the Smart Setup Wizard” on 
page 1-1.
If your router can obtain an IP address, but your computer is unable to load any Web pages from 
the Internet:
• Your computer might not recognize any DNS server addresses. 
A DNS server is a host on the Internet that translates Internet names (such as www addresses) 
to numeric IP addresses. Typically, your ISP provides the addresses of one or two DNS servers 
for your use. If you entered a DNS address during the router’s configuration, reboot your 
computer, and verify the DNS address as described in the online document you can access 
from “Preparing Your Network” in Appendix B. You can also configure your computer 
manually with DNS addresses, as explained in your operating system documentation.
• Your computer might not have the router configured as its TCP/IP gateway.
If your computer obtains its information from the router by DHCP, reboot the computer, and 
verify the gateway address as described in the online document you can access from 
“Preparing Your Network” in Appendix B.
• 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.

Troubleshooting a Network Using the Ping Utility
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. Troubleshooting a network is 
made very easy by using the ping utility in your computer or workstation.
Testing the LAN Path to Your Router
You can ping the router from your computer to verify that the LAN path to your router is set up 
correctly.
To ping the router from a 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.net
3.Click OK.
You should see a message like this one:
Pinging  with 32 bytes of data
If the path is working, you see this message:
Reply from < IP address >: bytes=32 time=NN ms TTL=xxx
If the path is not working, you see this message:
Request timed out
If the path is not functioning correctly, you could have one of the following problems:
• Wrong physical connections
– 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 “The Internet 
or Ethernet port lights are not on.” on page 7-4.
– Check that the corresponding Link lights are on for your network interface card. 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.

7-8Troubleshooting
v1.1, May 2008
– Verify that the IP address for your router and your computer are correct and that the 
addresses are on the same subnet.
Testing the Path from Your Computer to a Remote Device
After 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 
where  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 
“Configuring Your Internet Connection Using the Smart Setup Wizard” on page 1-1.
