Using the Smart Wizard to Set Up Your Modem
For first-time installation of your modem refer to the Broadband ADSL2+ Modem Setup Manual.
The Setup Manual explains how to launch the NETGEAR Smart Wizard on the Resource CD to
step you through the procedure to connect your modem and computer. The Smart Wizard will
assist you in configuring your wireless settings and enabling wireless security for your network.
After initial configuration using the Setup Manual, you can use the information in this manual to
configure additional features of your modem.
For installation instructions in a language other than English, see the language options on the
Resource CD.
Logging In to the Modem
You can log in to the modem to view or change its settings.
1. On your PC, open a Web browser, such as Microsoft Internet Explorer, and type the URL
http://192.168.0.1 in the address box. A dialog screen will be displayed prompting you for a
user name and password.
Note: The Smart Wizard cannot detect a PPTP connection with your ISP. If your ISP uses
this protocol, then you must use Quick Setup to configure your connection manu-
ally. See “Using Quick Setup to Configure the Modem” on page 1-6.
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

Setting Up Your Modem Manually
If you elect not to use the Smart Wizard, you can set up the modem manually. However, you need
to prepare the following before you can set up your modem:
• 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 Broadband ADSL2+ Modem Setup Manual.
• Your computer must be set up to use DHCP to get its TCP/IP configuration from a 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 Your Network” in Appendix B.
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.
You can use the Setup Wizard to auto-detect your Internet connection, or you can bypass the
wizard and enter settings in the Quick Setup screens.
•Setup Wizard. This wizard searches your Internet connection for servers and protocols to
determine your Internet Service Provider (ISP) configuration. See the following section,
“Using Quick Setup to Configure the Modem”.
Note: The Setup Wizard cannot detect a PPTP connection with your ISP. If your ISP
uses this protocol, then you must use Quick Setup to configure your connection
manually.

VPI The Virtual Path Identifier (VPI) identifies the virtual path between
endpoints in an ATM network. The valid range is from 0 to 255.
VCI The Virtual Channel Identifier (VCI) identifies the virtual channel
endpoints in an ATM network. The valid range is from 32 to 65535 (1 to
31 are reserved for well-known protocols).
Protocol Select the service that is provided by your ISP:
•RFC2684 Bridging. Multiprotocol Encapsulation over ATM
Adaptation Layer 5 service.
•PPPoE Bridging. PPP over Ethernet service.
•PPPoA Bridging. PPP over ATM service.
Multiplexing Method Select the multiplexing service that is provided by your ISP:
•LLC-Based. Logical link control multiplexing.
•VC-Based. Virtual circuit multiplexing.
PPP username Enter your login user name. This fields is case-sensitive.
PPP password Enter you login password. This fields is case-sensitive.
Disconnect if no activity (in
minutes)
This is also known as the PPP idle timer. When the PPP idle timer is
configured as zero, the PPP connection remains always on. However,
when the PPP idle timer has a value other than zero, the PPP
connection will be terminated when the configured period of inactivity is
reached.
MTU Size (in bytes) 1492 bytes is the default value for PPPoE. 1500 bytes is the default
value for PPPoA. Do not changes these values unless your ISP asks
you to do so.

LAN IP Setup
If you intend to connect your modem to a router, configure the local area network Internet Protocol
(LAN IP) settings, as follows:
1. Select LAN IP Setup from the main menu to display the following screen:
2. Check the LAN IP address of your router, which is usually printed on a label on the bottom or
at the rear of the device.
Note how the address is comprised of four numbers separated by period characters. If
necessary, change the LAN IP address of the modem so that the two left-most numbers of the
address are the same as the two left-most numbers of the router’s LAN IP address, and the
third number in the modem’s address is different from the third number in the router’s address.
For example, if the router’s LAN IP address is the same as the modem’s default address
(192.168.0.1), change the LAN IP address of the modem to 192.168.1.1.
Figure 1-5
Tip: If you change the LAN IP address of the modem, write the new address on a
sticky label and attach it to the bottom of the unit. You will need the new
address to access the modem management utility in the future.

3. By default, most routers (and all NETGEAR routers) include an active DHCP server. If this is
the case for your router, click the Off radio button to disable the DHCP server in the modem.
4. If you changed the LAN IP address or DHCP server setting, click Apply to make the new
settings take effect.
Understanding the LAN IP Settings
The following table explains the fields and button on the LAN IP Setup screen.
How the Internet Connection Works
Your modem is now configured to provide Internet access for your network. Your modem
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 performs these functions automatically as needed.
To access the Internet from any computer connected to your modem, launch an Internet browser
such as Microsoft Internet Explorer. You should see the modem’s Internet LED blink, indicating
communication to the ISP. The browser should begin to display a Web page.
Note: If you change the LAN IP address, you will lose your connection to the modem
management utility. You will need to type the new IP address into your
browser address box to re-access the utility.
Table 1-3. LAN IP Settings
Settings Description
LAN IP Address The LAN IP address of the modem.
Subnet Mask The LAN subnet mask of the modem. Combined with the IP address, the IP Sub-
net Mask allows a device to know which other addresses are local to it, and
which must be reached through a gateway or modem.
DHCP Server The modem is set up by default to be a DHCP server, which provides TCP/IP
configuration for computers that are connected to it. If you are connecting the
modem to a network with a router that is the DHCP server, select the Off check
box, and then click Apply to save your change.
