Troubleshooting with the LEDs
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/Test LED
is on.
2.
Verify that the Power/Test LED turns amber within a few seconds, indicating that the self-test
is running.
3.
After approximately 30 seconds, verify that:
•
The Power/Test LED is solid green.
•
The Internet LED is on.
•
A numbered Ethernet port LED is on for any local port that is connected to a
computer. This indicates that a link has been established to the connected device.
The LEDs on the front panel of the router can be used for troubleshooting.
Power/Test LED Is Off or Blinking
•
Make sure that the power cord is securely connected to your router and that the power
adapter is securely connected to a functioning power outlet.
•
Check that you are using the 12V DC, 2.5A power adapter that NETGEAR supplied for
this product.
•
If the Power/Test 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, you have a hardware problem. For recovery
instructions, or help with a hardware problem, contact technical support at
www.netgear.com/support
.
Power/Test LED Stays Amber
When the router is turned on, the Power/Test LED turns amber for about 20 seconds and
then turns green. If the LED does not turn green, the router has a problem.
If the Power/Test LED is still amber 1 minute after turning on power to the router:
1.
Turn the power off and back on to see if the router recovers.
2.
Press and hold the
Restore Factory Settings
button to return the router to its factory
settings. See
Factory Settings
on page
109.
If the error persists, you might have a hardware problem and should contact technical
support at
www.netgear.com/support
.
LEDs Never Turn Off
When the router is turned on, the LEDs turns on for about 10 seconds and then turn off. If all
the LEDs stay on, there is a fault within the router.

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 could be a standard
straight-through Ethernet cable or an Ethernet crossover cable.
Wireless LEDs Are Off
If the Wireless LEDs stay off, check to see if the Wireless On/Off button on the router has
been pressed. This button turns the wireless radios in the router on and off. The Wireless
LEDs are lit when the wireless radio is turned on.
The Push 'N' Connect (WPS) Button Blinks Amber
If after using the WPS function the button blinks amber, check the following:
•
Make sure that you are using the button and not the router’s built-in registrar.
•
Check that PIN verification has succeeded for the wireless device you are adding to the
wireless network.
•
Make sure you have not pressed the WPS button on the top of the router after disabling
the WPS feature (you logged in to the router and disabled this previously).
•
Check that the router is not in the temporary AP setup locked state (if you are using the
wireless repeater function).
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 as described in the previous section.
•
Make sure that your computer’s IP address is on the same subnet as the router. If you are
using the recommended addressing scheme, your computer’s address should be in the
range of 192.168.1.2 to 192.168.1.254.
•
If your computer’s IP address is shown as 169.254.x.x, recent versions of Windows and
MacOS 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. This procedure is explained in
Factory Settings
on page
109.
•
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 quitting the browser and launching it again.
•
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 you
enter this information.
•
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.
Cannot Access the Internet
If you can access your router but you are unable to access the Internet, first determine
whether 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 Router Status screen.
To check the WAN IP address:
1.
Start your browser, and select an external site such as
.
2.
Access the router interface at
.
3.
Select
Administration > Router Status
.
4.
Check that an IP address is shown for the Internet port. If 0.0.0.0 is shown, your router has
not obtained an IP address from your ISP.
If your router cannot obtain an IP address from the ISP, you might need to force your cable or
DSL modem to recognize your new router by restarting your network, as described in
Sequence to Restart Your Network
on page
100.

N600 Wireless Dual Band Router WNDR3400v2
If your router is still unable to obtain an IP address from the ISP, the problem might be one of
the following:
•
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 in the Internet
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 clone your computer’s MAC address.
If your router can obtain an IP address, but your computer is unable to load any web pages
from the Internet:
•
Your computer might not recognize any DNS server addresses.
A DNS server is a host on the Internet that translates Internet names (such as www
addresses) to numeric IP addresses. Typically, your ISP provides the addresses of one or
two DNS servers for your use. If you entered a DNS address during the router’s
configuration, reboot your computer, and verify the DNS address.You can 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.
•
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 PPPoE
If you are using PPPoE, try troubleshooting your Internet connection.
To troubleshoot a PPPoE connection:
1.
Log in to the router.
2.
Select
Administration > Router Status
.
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
router continues 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 router does not authenticate
using PPPoE until data is transmitted to the network.
Troubleshooting 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:
•
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.
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 router configured as its default gateway.
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
Never dial a
connection
.
If the 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.
Changes Not Saved
If the router does not save the changes you make in the router interface, check the following:
