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.
•
LAN connected computers must be configured to obtain an IP address automatically using
DHCP. For more information, see the links in
Appendix B, “Related Documents
.
•
Some cable modem services require you to use the MAC address of the computer registered
on the account. If so, in the Router MAC Address section of the Basic Settings menu, select
Use this Computer’s MAC Address
. Click
Apply
to save your settings. Restart the network
in the correct sequence.
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

The LAN port lights are lit for any local ports that are connected.
If a port’s light is lit, a link has been established to the connected device. If a LAN port is
connected to a 100 Mbps device, verify that the port’s light is green. If the port is 10 Mbps,
the light will be amber.
c.
The Internet port is connected and its light is lit.
4.
If you have enabled WPS security, verify that the push-button stops blinking and changes to
green (otherwise the push-button light should be off).
If the correct behavior does not occur, see the appropriate following section.
The Power light is not on.
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 power adapter supplied by NETGEAR for this product.
If the error persists, you have a hardware problem and should contact Technical Support.
The Power light blinks green slowly and continuously.
The router firmware is corrupted.
To restore your firmware:

The Power light stays amber.
When the router is turned on, the Power light turns amber for about 20 seconds and then turns
green. If the light does not turn green, the router has a problem.
If the Power light 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.
Clear the router’s configuration to factory defaults. This will set the router’s IP address to
www.routerlogin.net. This procedure is explained in
“Restoring the Default Configuration and
Password” on page 7-12
.
If the error persists, you might have a hardware problem and should contact Technical Support.
The Internet light stays amber.
When the router is turned on, the Internet light turns amber for about 20 seconds and then turns
green. If the light does not turn green, the router has a problem.
If the Internet light is still amber 1 minute after turning on power to the router:
1.
The Internet is not accessible. Confirm that you have the correct internet setting.
2.
Clear the router’s configuration to factory defaults. This will set the router’s IP address to
www.routerlogin.net. This procedure is explained in
“Restoring the Default Configuration and
Password” on page 7-12
.
3.
Turn the power off and back on to see if the router recovers.
The Internet or LAN port lights are not on.
If either the LAN or Internet lights do not light when the Ethernet connection is made, check the
following:
1.
Make sure that the Ethernet cable connections are secure at the router and at the computer.
2.
Make sure that power is turned on to the connected computer.
3.
Be sure you are using Ethernet cables like the cable that was supplied with the wireless router.
See the
NETGEAR Wireless-N Router Setup Manual
for instructions.
The Push 'N' Connect (WPS) push-button blinks amber.
If after using the WPS function the push-button blinks amber, check the following:
1.
Make sure that you are using the push-button and not the router’s built-in registrar.

2.
Check that PIN verification has succeeded for the WPS-enabled device you are connecting to
the router.
3.
Make sure you have not pushed the push-button after disabling the WPS function (you logged
into the router and disabled this previously).
4.
Check that the router is not in the temporary AP setup locked state (if you are using the
wireless repeater function).
For more information on WPS, see
“Using Push 'N' Connect (Wi-Fi Protected Setup)” on
page 2-13
.
Login Problems
If you are unable to log in to the wireless router, 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
NETGEAR Wireless-N Router Setup Manual
.
•
Make sure you are using the correct login information. The factory default login name is
admin
and the password is
password
. Make sure that the Caps Lock is off when entering this
information.
•
Make sure your computer’s IP address is on the same subnet as the router. If your 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. Refer to your computer’s documentation or see
“Preparing Your
Network” in Appendix B
for help with configuring your computer.
•
If your router’s IP address has been changed and you don’t know the current IP address, reset
the router’s configuration to the factory defaults. This procedure will reset the router’s IP
address to 192.168.1.1 (see
“Default Configuration Settings” in Appendix A
).
•
Make sure your browser has Java, JavaScript, or ActiveX enabled. If you are using Internet
Explorer, click Refresh to be sure the Java applet is loaded. Try closing the browser and
reopening it again.
Note:
If your computer cannot reach a DHCP server, some operating systems will
assign an IP address in the range 169.254.x.x. If your IP address is in this
range, verify that you have a good connection from the computer to the router,
then restart (reboot) your computer.
