N900 WiFi Router
Troubleshoot with the LEDs
You can use the LEDs to identify setup or performance problems in the router and to isolate
the cause.
Standard LED Behavior When the Router Is Powered On
After you turn on power to the router, make sure 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 green.
•
The Internet ED is lit.
•
The 2.4 GHz and 5 GHz LEDs are lit unless you turned off the wireless radios.
You can use the LEDs on the front panel of the router for troubleshooting.
Power LED Is Off or Blinking
Do the following:
•
Make sure that the power adapter is securely connected to your 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 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 lights amber for up to two minutes and then
turns green. If the LED does not turn green, 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:
1.
Turn off the power and then turn it back on to see if the router recovers.
2.
Press and hold the
Reset
button to return the router to its factory settings.
See
Factory Settings
on page
155.
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
155.
If the error persists, a hardware problem might be the cause. Contact technical support at

.
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
a wireless radio is turned on.
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, this is because 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
155.
•
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.
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.com
.
3.
Type
or
.
A login screen displays.
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

N900 WiFi Router
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
Setup screen.
•
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.
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
or
.
A login screen displays.

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 screen displays.
4.
Click the
ADVANCED
tab.
The ADVANCED Home screen displays.
5.
In the Internet Port pane, click the
Connection Status
button.
The Connection Status screen displays.
6.
Check the Connection Status screen to see if your PPPoE connection is 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:
•
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.
•
The router 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.
