Quick Tips
This section describes tips for troubleshooting some common problems.
Sequence to Restart Your Network
When you 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.
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.
WiFi Settings
Make sure that the WiFi settings in the computer and router match exactly.The WiFi network name (SSID) and WiFi
security settings of the router and the computer or WiFi-capable device must match exactly.
If you set up an access list on the Wireless Settings page, you must add each computer or WiFi device’s MAC
address to the router’s access list.
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. Pressing the
LED
button on the front panel of the
router turns the LEDs on and off.
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:
Troubleshooting
181
Page 182 / 193
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 WiFi radios.
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 two 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 191.
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 191.
If the error persists, a hardware problem might be the cause. Contact technical support at
www.netgear.com/support
.

2.4 GHz, 5 GHz-1, and 5 GHz-2 WiFi LEDs Are Off
If these LEDs stay off, check to see if someone pressed the
WIFI
button on the front of the router. This button turns
the WiFi radios in the router on and off. These LEDs are lit when the WiFi radios are turned on.
Internet or Ethernet Port LEDs Are Off
If the Internet LED or the Ethernet port LEDs 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.
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 191.
•
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.
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.
Troubleshooting
183
Page 184 / 193
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.
Enter
.
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 page displays.
5.
Click the
ADVANCED
tab.
The ADVANCED Home page 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 181.
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 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.
Troubleshooting
184
Page 185 / 193
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.
