Lights Never Turn Off

When the router is turned on, the lights turns on for about 10 seconds and then turn off. If all the

lights stay on, there is a fault within the router.

If all lights are still on one minute after power up:

•

Cycle the power to see if the router recovers.

•

Clear the router’s configuration to factory defaults. This will set the router’s IP address to

192.168.1.1. This procedure is explained in

“Restoring the Default Configuration and

Password” on page -7

.

If the error persists, you might have a hardware problem and should contact technical support.

LAN or Internet Port Lights Not On

If either the LAN lights or Internet light do 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 hub or

workstation.

•

Make sure that power is turned on to the connected hub or workstation.

•

Be sure you are using the correct cable.

Troubleshooting the Web Configuration Interface

If you are unable to access the router’s Web Configuration interface from a computer on your local

network, check the following:

•

Check the Ethernet connection between the computer and the router as described in the

previous section.

•

Make sure 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. Refer to

“Preparing a Computer for Network Access” in

Appendix B

for instructions on how to verify TCP/IP properties and for instructions on how to

configure your computer.

•

If your router’s IP address has been changed and you do not know the current IP address, clear

the router’s configuration to factory defaults. This will set the router’s IP address to

192.168.1.1. This procedure is explained in

“Restoring the Default Configuration and

Password” on page -7

.

•

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 quitting the browser and launching it again.

•

Make sure 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 entering this

information.

If the router does not save changes you have made in the Web Configuration Interface, check the

following:

•

When entering configuration settings, be sure to click Apply before moving to another menu

or tab, or your changes will be lost.

•

Click the Refresh or Reload button in the Web browser. The changes may have occurred, but

the Web browser may be caching the old configuration.

Troubleshooting the ISP Connection

If your router is unable to access the Internet, you should first determine whether the router is able

to obtain a WAN IP address from the ISP. Unless you have been assigned a static IP address, your

router must request an IP address from the ISP. You can determine whether the request was

successful using the Web Configuration Manager.

Troubleshooting

v3.0, 2006-03

To check the WAN IP address:

1.

Launch your browser and select an external site such as www.netgear.com.

2.

Access the Main Menu of the router’s configuration at

.

3.

Under the Maintenance heading, select Router Status.

4.

Check that an IP address is shown for the Internet (WAN) Port.

If 0.0.0.0 is shown, your router has not obtained an IP address from your ISP.

If your router is unable to obtain an IP address from the ISP, you may need to force your cable or

DSL modem to recognize your new router by performing the following procedure:

1.

Turn off power to the cable or DSL modem.

2.

Turn off power to your router.

3.

Wait five minutes and reapply power to the cable or DSL modem.

4.

When the modem’s lights indicate that it has reacquired sync with the ISP, reapply power to

your router.

5.

Then restart your computer.

If your router is still unable to obtain an IP address from the ISP, the problem may be one of the

following:

•

Your ISP may 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, you may have incorrectly set the login name and password.

•

Your ISP may check for your computer's host name.

Assign the computer Host Name of your ISP account as the Account Name in the Basic

Settings menu.

•

Your ISP only allows one Ethernet MAC address to connect to Internet, and may check for

your computer’s MAC address. In this case:

Inform your ISP that you have bought a new network device, and ask them to use the router’s

MAC address.

OR

Configure your router to spoof your computer’s MAC address. This can be done in the Basic

Settings menu.

If your router can obtain an IP address, but your computer is unable to load any Web pages from

the Internet:

•

Your computer may 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 will provide 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 as described in

“Preparing a Computer for

Network Access” in Appendix B

. Alternatively, you may configure your computer manually

with DNS addresses, as explained in your operating system documentation

.

•

Your computer may 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. For details, see

“Preparing a Computer for Network Access” in

Appendix B

.

Troubleshooting a TCP/IP Network Using a Ping Utility

Most TCP/IP terminal 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. Troubleshooting a TCP/IP

network is made very easy by using the ping utility in your computer or workstation.

Testing 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 PC running Windows 95 or later:

1.

From the Windows toolbar, click on the Start button and select Run.

2.

In the field provided, type Ping followed by the IP address of the router, as in this example:

ping 192.168.1.1

3.

Click on OK.

You should see a message like this one:

Pinging <IP address> with 32 bytes of data

If the path is working, you see this message:

Reply from < IP address >: bytes=32 time=NN ms TTL=xxx

If the path is not working, you see this message:

Request timed out

Troubleshooting

v3.0, 2006-03

If the path is not functioning correctly, you could have one of the following problems:

•

Wrong physical connections

–

Make sure the LAN port LED is on. If the LED is off, follow the instructions in

“LAN

or Internet Port Lights Not On

” on

page 5-2

.

–

Check that the corresponding Link LEDs are on for your network interface card and

for the hub ports (if any) that are connected to your workstation and router.

•

Wrong network configuration

–

Verify that the Ethernet card driver software and TCP/IP software are both installed

and configured on your computer or workstation.

–

Verify that the IP address for your router and your workstation are correct and that the

addresses are on the same subnet.

Testing the Path from Your Computer to a Remote Device

After verifying that the LAN path works correctly, test the path from your computer to a remote

device. From the Windows run menu, type:

PING -n 10

<

IP address

>

where <

IP address

> is the IP address of a remote device such as your ISP’s DNS server.

If the path is functioning correctly, replies as in the previous section are displayed. If you do not

receive replies:

–

Check that your computer has the IP address of your router listed as the default gateway. If

the IP configuration of your computer is assigned by DHCP, this information will not be

visible in your computer’s Network Control Panel. Verify that the IP address of the router

is listed as the default gateway. For details, refer to

“Preparing a Computer for Network

Access” in Appendix B

.

–

Check to see that the network address of your computer (the portion of the IP address

specified by the netmask) is different from the network address of the remote device.

–

Check that your cable or DSL modem is connected and functioning.

–

If your ISP assigned a host name to your computer, enter that host name as the Account

Name in the Basic Settings menu.
