•
Cycle the power to see if the router recovers.
•
Press and hold the
Restore Factory Settings
button to return the router to its factory
settings as explained in
Troubleshoot Your Network Using the Ping Utility
on page 100.
If the error persists, you might have a hardware problem and should 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 could be a standard
straight-through Ethernet cable or an Ethernet crossover cable.
Wireless LED Is Off
If the Wireless LED stays 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
LED is 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 side 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 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 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 103.
•
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 94.

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.
•
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
Maintenance > 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 log in 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
.
Changes Not Saved
If the router does not save the changes you make in the router interface, check 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. The changes might have
occurred, but the old settings might be in the web browser’s cache.

Wireless Connectivity
If you are having 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 Wireless LED on the front of the router. It should be lit. If it is not, you can
press the
Wireless
button on the side of the router to turn the router’s wireless radio back
on.
If you disabled the router’s SSID broadcast, then your wireless network is hidden and
does not show up 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 Settings
see (
Basic Wireless Settings
on page 26).
Note:
Be sure to click
Apply
if you make changes.
Wireless Signal Strength
If your wireless device finds your network, but the signal strength is weak, check these
conditions:
•
Is your router too far from your computer, or too close? Place your computer near the
router, but at least 6 feet away, and see whether the signal strength improves.
•
Is your wireless signal blocked by objects between the router and your computer?
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
troubleshooting a network by 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 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:
