What You Need Before You Begin
You need to prepare the following before you can set up your modem router:
• Active Internet service provided by an ADSL account.
• The Internet Service Provider (ISP) configuration information for your ADSL account.
– ISP login name and password
– ISP Domain Name Server (DNS) addresses
– Fixed or static IP address
– Host and domain names
• Depending on how your ISP set up your Internet account, you need to know one or more of
these settings:
– Virtual path identifier (VPI) and Virtual channel identifier (VCI) parameters
– Multiplexing method
– Host and domain names
• ASDL microfilters as explained in the NETGEAR Router Setup Manual.
• Your computer must be set up to use DHCP to get its TCP/IP configuration from the modem
router. This is usually the case. For help with DHCP, see the documentation that came with
your computer, or see the link to the online document in “Preparing a Computer for Network
Access” in Appendix C.
Your ISP should have provided you with all the information needed to connect to the Internet. If
you cannot locate this information, you can ask your ISP to provide it.
Logging In to the Modem Router
You can log in to the modem router to view or change its settings.
Note: Your computer must be configured for DHCP. For help with configuring DHCP, see
the documentation that came with your computer or see the link to the online
document in “Preparing a Computer for Network Access” in Appendix C.

only from the MAC address of that computer. This feature
allows your modem router to masquerade as that computer by
“cloning” its MAC address.
• Use Default Address. Use the default MAC address.
• Use Computer MAC Address. The modem router will
capture and use the MAC address of the computer that you
are now using. You must be using the one computer that is
allowed by the ISP.

ADSL Settings
Note: For information about how to install ADSL filters, see the NETGEAR Router Setup
Manual.
The default ADSL settings of your modem router work fine for most ISPs. However, some ISPs
use a specific multiplexing method and virtual circuit number for the virtual path identifier (VPI)
and virtual channel identifier (VCI).
Note: You must use the Setup Wizard to select the correct country for the default ADSL
settings to work.
If your ISP provided you with a multiplexing method or VPI/VCI number, then enter the setting:
1. From the main menu, select ADSL Settings.
2. In the Multiplexing Method drop-down list, select LLC-based or VC-based.
3. Type a number between 0 and 255 for the VPI. The default is 8.
4. Type a number between 32 and 65535 for the VCI. The default is 35.
5. Click Apply.
How the Internet Connection Works
Your modem router is now configured to p r ovide Internet access for your network. Your modem
router automatically connects to the Internet when one of your computers requires access. It is not
necessary to run a dialer or login application such as dial-up networking or Enternet to connect,
log in, or disconnect. The modem router performs these functions automatically as needed.
To access the Internet from any computer connected to your modem router, launch an Internet
browser such as Microsoft Internet Explorer or Netscape Navigator. You should see the modem
router’s Internet LED blink, indicating communication to the ISP. The browser should begin to
display a Web page.

Chapter 2
Wireless Configuration
This chapter describes how to configure the wireless features of your ADSL2+ Modem Wireless
Router. In planning your wireless network, consider the level of security required. Y ou should also
select the physical placement of your modem router to maximize the network speed.
Note: If you are configuring the modem router from a wireless PC and you change the
modem router’s SSID, channel, or wireless security settings, you will lose your
wireless connection when you click Apply. You must then change the wireless
settings of your PC to match the modem router’s new settings.
For proper compliance and compatibility between similar products in your area, you must set the
operating channel and region correctly.
Set up wireless features for the modem router in this order:
1. Connect the modem router, and get the Internet connection working, as described in
Chapter 1, “Configuring Your Internet Connection”. The modem router should work with an
Ethernet LAN connection before you set up the wireless features.
2. Plan the location for the modem router based on considerations in “W ireless Placement and
Range Guidelines”.
3. Enter the wireless settings, and verify wireless connectivity, as described in “Viewing or
Changing Wireless Settings”.
4. Implement wireless security, as described in “Wireless Security”.
For more information about wireless technology, see the link to the online document in “Wireless
Communications” in Appendix C.

Wireless Placement and Range Guidelines
The range of your wireless connection can vary significantly based on the physical placement of
the modem router. The latency , data th roughput performance, and n otebook power consumption of
wireless adapters also vary depending on your configuration choices.
For best results, place your modem router according to the following guidelines:
• Near the center of the area in which your PCs will operate.
• In an elevated location such as a high shelf where the wirelessly connected PCs have line-ofsight access (even if through walls).
• Away from sources of interference, such as PCs, microwave ovens, and 2.4 GHz cordless
phones.
• Away from large metal surfaces.
• Put the antenna in a vertical position to provide the best side-to-side coverage. Put the antenna
in a horizontal position to provide the best up-and-down coverage.
• If using multiple access points, it is better if adjacent access points use different radio
frequency channels to reduce interference. The recommended channel spacing between
adjacent access points is 5 channels (for example, use Channels 1 and 6, or 6 and 11).
The time it takes to establish a wireless connection can vary depending on both your security
settings and placement. WEP connections can take slightly longer to establish. Also, WEP
encryption can consume more battery power on a notebook computer.
Viewing or Changing Wireless Settings
You can view or change the wireless settings for the modem router. If you want to make changes,
make sure to note the current settings first.
Note: If you use a wireless computer to change the wireless settings, you will be
disconnected when you click Apply. Reconfigure your wireless computer to match
the new settings, or access the modem router from a wired computer to make
further changes.
1. Log in to the modem router at its default LAN address of http://192.168.0.1 with its default
user name of admin, and default password of password, or using whatever user name,
password, and LAN address you have chosen for the modem router.

6. Configure and test your computers for wireless connectivity.
Program the wireless adapter of your computers to have the same SSID and wireless security
settings as your modem router. Check that they have a wireless link and are able to obtain an
IP address by DHCP from the modem router. If there is interference, adjust the channel.
