Manual Setup
Use the topics and procedures below to manually set up your wireless ADSL modem router.
Understanding ADSL Microfilters
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.
ADSL Microfilter
Each device such as a telephone, fax machine, answering machine, or caller ID display will require
an ADSL microfilter.
Note: If you purchased the wireless ADSL modem router in a country where a microfilter
is not included, you must acquire one.
Figure 1-3
Warning: Do not connect the wireless ADSL modem router to the ADSL line through a
microfilter unless the microfilter is a combination microfilter/splitter
specifically designed for this purpose. Doing so will prevent block your
connection to the Internet. If you have any doubts about this, connect the
wireless ADSL modem router directly to the ADSL line.

7. Configure and test your computers for wireless connectivity.
Program the wireless adapter of your computers to have the same wireless network name
(SSID) as the wireless ADSL modem router. Check that they have a wireless link and are able
to obtain an IP address by DHCP from the router.
Implement Appropriate Wireless Security
Unlike wired network data, your wireless data transmissions can extend beyond your walls and
can be received by anyone with a compatible adapter. For this reason, use the security features of
your wireless equipment. The wireless ADSL modem router provides highly effective security
features which are covered in detail in full reference manual that is available from a link on the CD
as well as a link in the main menu of your router. Follow the instructions in the full manual and in
the router help screens to deploy the security features appropriate to your needs.
Note: If you are configuring the router from a wireless computer and you change the
router’s SSID, channel, or security settings, you will lose your wireless
connection when you click Apply. You must then change the wireless settings
of your computer to match the router’s new settings.
Warning: Indoors, computers can connect over wireless networks at a range of several
hundred feet. Such distances can allow for others outside of your immediate
area to access your network.

Chapter 2
Troubleshooting
This chapter gives information about troubleshooting your wireless ADSL modem router. After
each problem description, instructions are provided to help you diagnose and solve the problem.
For the common problems listed, go to the section indicated.
• Is the router on?
Go to “Basic Functioning” on page 2-1.
• Have I connected the router correctly?
Go to “Basic Functioning” on page 2-1.
• I cannot access the router’s configuration with my browser.
Go to “Troubleshooting the Web Configuration Interface” on page 2-3.
• I have configured the router but I can’t access the Internet.
Go to “Troubleshooting the ISP Connection” on page 2-4.
• I cannot remember the router’s configuration password.
Go to “Using the Reset Button” on page 2-9.
• I want to clear the configuration and start over again.
Go to “Restoring the Default Configuration and Password” on page 2-8.
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. After approximately 10 seconds, verify that:
a. The LAN port LEDs are lit for any local ports that are connected.
b. The ADSL Internet port LED is lit.

Wireless ADSL2+ Modem Router Setup Manual
2-2 Troubleshooting
v1.0, 2006-4
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.
Power LED is Red
When the router is turned on, it performs a power-on self test. If the Power LED turns red after a
few seconds or at any other time during normal operation, there is a fault within the router. The
power LED also turns red when you depress the factory default reset push button, and blinks red 3
times when that button is released. However, in this case, the wireless ADSL modem router is
working normally.
If the power LED turns red to indicate a router fault:
• Cycle the power to see if the router recovers.
If the power LED is still red 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.
LAN or 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:
