LEDs Never Turn Off
When the router is turned on, the LEDs turns on for about 10 seconds and then turns off. If all the
LEDs stay on, there is a fault within the router.
If all LEDs are still on one minute after power up:
•
Cycle the power to see if the router recovers.
•
Clear the router’s configuration to the factory defaults. This will set the router’s IP address to
192.168.0.1. This procedure is explained in
“Restoring the Default Configuration and
Password” on page 11-7
.
If the error persists, you might have a hardware problem and should contact technical support.
LAN or Internet Port LEDs Not On
If either the LAN LEDs or the Internet LED 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:
When connecting the router’s Internet port to a broadband modem, use the cable that was
supplied with the broadband modem. This cable could be a standard straight-through Ethernet
cable or an Ethernet crossover 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
192.168.0.2 to 192.168.0.254.
Note:
If your computer’s IP address is shown as 169.254.x.x: Recent versions of Windows
and MacOS will 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 has been changed and you do not know the current IP address, clear
the router’s configuration to the factory defaults. This will set the router’s IP address to
192.168.0.1. This procedure is explained in
“Restoring the Default Configuration and
Password” on page 11-7
.
•
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 the APPLY button 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.
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 http://192.168.0.1.
3.
Under the Maintenance heading, select Router Status.
4.
Check that an IP address is shown for the 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
broadband modem to recognize your new router by performing the following procedure:
1.
Turn off power to the broadband modem.
2.
Turn off power to your router.
3.
Wait five minutes and reapply power to the broadband modem.
4.
When the modem’s LEDs indicate that it has reacquired sync with the ISP, reapply power to
your router.
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. Refer to
“Manually Configuring Your Internet Connection” on page 3-18
.
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. 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.
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 computer 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:
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:

Troubleshooting

Reply from < IP address >: bytes=32 time=NN ms TTL=xxx
If the path is not working, you see this message:
Request timed out
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 LEDs Not On
” on
page 11-2
.
—
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.
—
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 broadband 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.
