							Quick Tips
This section describes tips for troubleshooting some common problems.
Sequence to Restart Your Network
When you need to restart your network, follow this sequence:
1.Turn off and unplug the modem.
2.Turn off the router.
3.Plug in the modem and turn it on.Wait two minutes.
4.Turn on the router and wait two minutes.
Check Ethernet Cable Connections
If your device does not power on, make sure that the Ethernet cables are securely plugged in.The Internet
LED on the router is lit if the Ethernet cable connecting the router and the modem is plugged in securely
and the modem and router are turned on. If one or more powered-on computers are connected to the
router by an Ethernet cable, the corresponding numbered router LAN port LED lights.
Wireless Settings
Make sure that the wireless settings in the computer and router match exactly.The wireless network name
(SSID) and wireless security settings of the router and wireless computer must match exactly.
If you set up an access list in the Advanced Wireless Settings page, you must add each wireless computer’s
MAC address to the router’s access list.
Network Settings
Make sure that the network settings of the computer are correct.Wired and wirelessly connected computers
must use 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.
Some cable modem service providers require you to use the MAC address of the computer initially
registered on the account.You can view the MAC address on the Attached Devices page.
Troubleshoot with the LEDs
By default, the router is set with standard LED settings. If you turned off the LEDs except the Power LED,
you must return the LEDs to their standard settings for troubleshooting. For information about controlling
the LED settings, see Turn the LEDs On or Off on page 12.

							Standard LED Behavior When the Router Is Powered On
After you turn on power to the router, verify that the following sequence of events occurs:
1.When power is first applied, verify that the Power LED  is lit.
2.After about two minutes, verify the following:
•The Power LED is solid white.
•The Internet LED is lit.
•The WiFi LED is lit unless you turned off the wireless radio.
You can use the LEDs on the front panel of the router for troubleshooting.
Power LED Is Off or Blinking
This could occur for a number of reasons. Check the following:
•Make sure that the power adapter is securely connected to your router and securely connected to a
working power outlet.
•Make sure that you are using the power adapter that NETGEAR supplied for this product.
•If the Power LED blinks slowly and continuously, the router firmware is corrupted.This can happen if
a firmware upgrade is interrupted, or if the router detects a problem with the firmware. If the error
persists, it is likely that a hardware problem exists. For recovery instructions, or help with a hardware
problem, contact technical support at www.netgear.com/support.
Power LED Stays Amber
When the router is turned on, the Power LED turns amber for up to 2 minutes and then turns white. If the
LED does not turn white, this indicates a problem with the router.
If the Power LED is still amber three minutes after you turn on power to the router, do the following:
•Cycle the power to see if the router recovers.
•Press and hold the Reset button to return the router to its factory settings. For more information, see
Factory Settings on page 181.
If the error persists, a hardware problem might be the cause. Contact technical support at
www.netgear.com/support.
LEDs Never Turn Off
When the 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 router.
If all LEDs are still lit one minute after power-up, do the following:

							•Cycle the power to see if the router recovers.
•Press and hold the Reset button to return the router to its factory settings. For more information, see
Factory Settings on page 181.
If the error persists, a hardware problem might be the cause. Contact technical support at
www.netgear.com/support.
Internet or Ethernet Port LEDs Are Off
If either the Ethernet port LEDs or the Internet LED does not light when the Ethernet connection is
made, check the following:
•Make sure that the Ethernet cable connections are secure at the router and at the modem or computer.
•Make sure that power is turned on to the connected modem or computer.
•Be 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 can be a standard straight-through Ethernet cable or an Ethernet
crossover cable.
WiFi LED Is Off
If the WiFi LED stays off, check to see if someone pressed the WiFi On/Off button on the router.This
button turns the wireless radios in the router on and off.The WiFi LED is lit when the wireless radio is
turned on.
You Cannot Log In to the Router
If you are unable to log in to the router from a computer on your local network, check the following:
•If you are using an Ethernet-connected computer, check the Ethernet connection between the computer
and the router.
•Make sure that the IP address of your computer is on the same subnet as the router. If you are using
the recommended addressing scheme, your computer’s address is in the range of 192.168.1.2 to
192.168.1.254.
•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 autogenerated

							addresses are in the range of 169.254.x.x. If your IP address is in this range, check the connection
from the computer to the router, and reboot your computer.
•If your router’s IP address was changed and you do not know the current IP address, clear the router’s
configuration to factory defaults.This sets the router’s IP address to 192.168.1.1. For more information,
see Factory Settings on page 181.
•Make sure that Java, JavaScript, or ActiveX is enabled in your browser. 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.
•Make sure that you are using the correct login information.The user name is admin, and the default
password is password. Make sure that Caps Lock is off when you enter this information.
•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, the router cannot convert
ADSL or cable data into Ethernet networking information. NETGEAR does not support such a
configuration.
You Cannot Access the Internet
If you can access your router but not the Internet, check to see if the router can obtain an IP address from
your Internet service provider (ISP). Unless your ISP provides a fixed IP address, your router requests
an IP address from the ISP.You can determine whether the request was successful using the ADVANCED
Home screen.
To check the WAN IP address:
1.Launch a web browser from a computer or wireless device that is connected to the network.
2.Select an external site such as www.netgear.comwww.netgear.com.
3.Type http://www.routerlogin.net .
A login window opens.
4.Enter the 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 screen displays.
5.Click the ADVANCED tab.
The ADVANCED Home screen displays.
6.Check that an IP address is shown for the Internet port. If 0.0.0.0 is shown, your router did not obtain
an IP address from your ISP.
If your router cannot obtain an IP address from the ISP, you might need to force your cable or DSL modem
to recognize your new router by restarting your network. For more information, see Sequence to Restart Your
Network on page 171.
If your router is still unable to obtain an IP address from the ISP, the problem might be one of the following:
Troubleshooting
174 
						

							•Your Internet service provider (ISP) might require a login program. Ask your ISP whether they require
PPP over Ethernet (PPPoE) or some other type of login.
•If your ISP requires a login, the login name and password might be set incorrectly.
•Your ISP might check for your computer’s host name. Assign the computer host name of your ISP account
as the account name on the Internet Setup page.
•If your ISP allows only one Ethernet MAC address to connect to Internet and checks for your computer’s
MAC address, do one of the following:
•Inform your ISP that you bought a new network device and ask them to use the router’s MAC address.
•Configure your router to clone your computer’s MAC address.
If your router obtained an IP address, but your computer is does not load any web pages from the Internet,
it might be for one or more of the following reasons:
•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.You can configure your computer manually with DNS addresses, as explained in your operating
system documentation.
•The router might not be configured as the TCP/IP gateway on your computer.
If your computer obtains its information from the router by DHCP, reboot the computer and verify the
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. Other browsers
provide similar options.
Troubleshooting
175 
						

							Troubleshoot PPPoE
If you are using PPPoE, try troubleshooting your Internet connection.
To troubleshoot a PPPoE connection:
1.Launch a web browser from a computer or wireless device that is connected to the network.
2.Type http://www.routerlogin.net .
A login window opens.
3.Enter the 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.Click the ADVANCED tab.
The ADVANCED Home page displays.
5.In the Internet Port pane, click the Connection Status button.
The Connection Status window opens.
6.Check the Connection Status windowto see if your PPPoE connection is up and working.
If the router is not connected, click the Connect button.
The router continues to attempt to connect indefinitely.
7.If you cannot connect after several minutes, the router might be set up with an incorrect service name,
user name, or password, or your ISP might be experiencing a provisioning problem.
Unless you connect manually, the router does not authenticate using PPPoE until data is transmitted to
the network.
Troubleshoot Internet Browsing
If your router can obtain an IP address but your computer is unable to load any web pages from the
Internet, check the following:
•The traffic meter is enabled, and the limit was reached.
By configuring the traffic meter not to block Internet access when the traffic limit is reached, you can
resume Internet access. If your ISP sets a usage limit, they might charge you for the overage.
•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, restart your computer.
Troubleshooting
176 
						

							Alternatively, you can configure your computer manually with a DNS address, as explained in the
documentation for your computer.
•The router might not be configured as the default gateway on your computer.
Reboot the computer and verify that the 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 the Never dial a connection. Other browsers provide similar options.
Changes Are Not Saved
If the router does not save the changes that you make in the router interface, do the following:
•When entering configuration settings, always click the Apply button before moving to another screen
or tab, or your changes are lost.
•Click the Refresh or Reload button in the web browser. It is possible that the changes occurred, but
the old settings might be in the web browser’s cache.
Troubleshoot Wireless Connectivity
If you are experiencing trouble connecting wirelessly to the router, try to isolate the problem:
•Does the wireless device or computer that you are using find your wireless network?
If not, check the WiFi LED on the front of the router. If it is off, you can press the WiFi On/Off button
on the router to turn the router wireless radios back on.
If you disabled the router’s SSID broadcast, then your wireless network is hidden and does not display
in your wireless client’s scanning list. (By default, SSID broadcast is enabled.)
•Does your wireless device support the security that you are using for your wireless network (WPA or
WPA2)?
•If you want to view the wireless settings for the router, use an Ethernet cable to connect a computer
to a LAN port on the router.Then log in to the router, and select BASIC > Wireless.
Be sure to click the Apply button if you change settings.Note
If your wireless device finds your network but the signal strength is weak, check these conditions:
Troubleshooting
177 
						

							•Is your router too far from your computer or too close? Place your computer near the router but at
least 6 feet (1.8 meters) away and see whether the signal strength improves.
•Are objects between the router and your computer blocking the wireless signal?
Troubleshoot Your 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.You can easily troubleshoot a network using the
ping utility in your computer or workstation.
Test 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 Windows computer:
1.From the Windows toolbar, click the Start button and select Run.
2.In the field provided, type ping followed by the IP address of the router, as in this example:
ping www.routerlogin.net
3.Click the OK button.
You 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, one of the following problems might be present:
•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 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 router.
•Wrong network configuration
Verify that the Ethernet card driver software and TCP/IP software are both installed and configured
on your computer.
Troubleshooting
178 
						

							Verify that the IP address for your router and your computer are correct and that the addresses are
on the same subnet.
Test the Path from Your Computer to a Remote Device
To test the path from your computer to a remote device.
1.From the Windows toolbar, click the Start button and 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 DNS server.
If the path is functioning correctly, messages display that are similar to those shown in Test the LAN
Path to Your Router on page 178.
3.If you do not receive replies, check the following:
•Check that IP address of your router is listed as the default gateway for your computer. 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 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
on 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 your ISP does this, configure your router to “clone” or “spoof” the MAC address from
the authorized computer.
