ADSL technology uses the same wires as your telephone service. However, ADSL adds signals to
the telephone lines which create noise in the telephone service. You must use ADSL microfilters to
filter out these signals before they reach your telephone.
Note: If the CD does not automatically start, browse the CD and double-click on
Autorun.
Note: If you purchased the ADSL modem router in a country where a microfilter is not
included, you must acquire one.

ADSL Microfilter
Each device such as a telephone, fax machine, answering machine, or caller ID display will require
an ADSL microfilter.
ADSL Microfilter with Built-In Splitter
Use an ADSL microfilter with built-in splitter when there is a single wall outlet which must
provide connectivity for both the ADSL modem router and telephone equipment.
Computers Set to DHCP
For the initial connection to your router, your computer has to be set to automatically get its
TCP/IP configuration from the router via DHCP. This is usually the case. The NETGEAR Smart
Wizard CD automatically takes care of this requirement. For manual setup, refer to the
documentation that came with your computer.
Manually Setting Up Your ADSL Modem Router
There are four steps to setting up your ADSL modem router:

• I want to clear the configuration and start over again.
Go to “Restoring the Default Configuration and Password” on page 2-9.
Basic Functioning
After you turn on power to the router, the following sequence of events should occur:
1. When power is first applied, verify that the Power LED is on (see “The Router’s Front Panel”
on page 1-2 for an illustration and explanation of the LEDs).
2. Verify that the Test LED lights within a few seconds, indicating that the self-test procedure is
running.
3. After approximately 10 seconds, verify that:
a. The Test LED is not lit.

ADSL Modem Router Setup Manual
2-2 Troubleshooting
v1.1, 2006-2
b. The LAN port LEDs are lit for any local ports that are connected.
c. The ADSL Internet port LED is lit.
If a port’s LED 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 LED is green. If the port is 10 Mbps, the
LED will be amber.
If any of these conditions does not occur, refer to the appropriate following section.
Power LED Not On
If the Power and other LEDs are off when your router is turned on:
• Make sure that the power cord is properly connected to your router and that the power supply
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.
Test LED Never Turns On or Test LED Stays On
When the router is turned on, the Test LED turns on for about 10 seconds and then turns off. If the
Test LED does not turn on, or if it stays on, there is a fault within the router.
If you experience problems with the Test LED:
• Cycle the power to see if the router recovers and the LED blinks for the correct amount of
time.
If all LEDs including the Test LED 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
192.168.0.1. This procedure is explained in “Using the Reset Button” on page 2-9.
If the error persists, you might have a hardware problem and should contact technical support.

v1.1, 2006-2
LAN or ADSL Internet Port LEDs Not On
If either the LAN LEDs or ADSL 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 ADSL port, use the cable that
was supplied with the ADSL modem router.
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:
• 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 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. Refer to “Preparing a Computer for Network Access” to find
your computer’s IP address.
• 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 will set the router’s IP address to 192.168.0.1.
This procedure is explained in “Using the Reset Button” on page 2-9.
• 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.
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.

2-4 Troubleshooting
v1.1, 2006-2
• 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 are 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 check the ADSL connection, then the
Internet TCP/IP connection.
ADSL link
If your router is unable to access the Internet, you should first determine whether you have an
ADSL link with the service provider. The state of this connection is indicated with the Internet
LED.
ADSL Internet LED Green or Blinking Green
If your ADSL Internet LED is green or blinking green, then you have a good ADSL connection.
You can be confident that the service provider has connected your line correctly and that your
wiring is correct.
ADSL Internet LED Blinking Yellow
If your ADSL Internet LED is blinking yellow, then your ADSL modem router is attempting to
make an ADSL connection with the service provider. The LED should turn green within several
minutes.
If the Internet LED does not turn green, disconnect all telephones on the line. If this solves the
problem, reconnect the telephones one at a time, being careful to use a microfilter on each
telephone. If the microfilters are connected correctly, you should be able to connect all your
telephones.
