Chapter 1
Connecting Your Router to the Internet
This chapter describes how to configure your DGN2000 Wireless-N ADSL2+ Modem Router
Internet connection. When you perform the initial configuration of your modem router using the
DGN2000 Wireless-N ADSL2+ Modem Router Resource CD as described in the Wireless-N
ADSL2+ Modem Router DGN2000 Setup Manual, these settings are configured automatically for
you. This chapter provides further details about these settings, as well as instructions on how to log
in to the modem router for further configuration.
Note: NETGEAR recommends using the Smart Wizard on the DGN2000 Wireless-N
ADSL2+ Modem Router Resource CD for initial configuration, as described in the
Wireless-N ADSL2+ Modem Router DGN2000 Setup Manual.
This chapter includes:
• “Using the Setup Manual”
• “What You Need before You Begin” on page 1-2”
• “Logging In to the Wireless Modem Router” on page 1-3”
• “Auto-detecting Your Internet Connection” on page 1-5”
• “Viewing or Manually Configuring Your ISP Settings” on page 1-6”
• “ADSL Settings” on page 1-11”
• “How the Internet Connection Works” on page 1-12”
Using the Setup Manual
For first-time installation of your modem router, refer to the Wireless-N ADSL2+ Modem Router
DGN2000 Setup Manual. The Setup Manual explains how to launch the NETGEAR Smart Wizard
on the DGN2000 Wireless-N ADSL2+ Modem Router Resource CD to step you through the
procedure to connect your router, modem, and computers. 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 Reference Manual to
configure additional features of your wireless router.

For installation instructions in a language other than English, see the language options on the
DGN2000 Wireless-N ADSL2+ Modem Router Resource CD.
What You Need before You Begin
You need to prepare the following before you can set up your firewall:
• 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 Wireless-N ADSL2+ Modem Router DGN2000 Setup
Manual
In addition, 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 that you can access from “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.

Auto-detecting Your Internet Connection
The Smart Setup Wizard searches your Internet connection for servers and protocols to determine
your ISP configuration.
Note: The wizard cannot detect a PPTP connection with your ISP. If your ISP uses this
protocol, then you must configure your connection manually (see “Understanding
the Basic Settings Screen” on page 1-8).
To use the Smart Setup Wizard to assist with configuration or to view the Internet connection
settings:
1. From the Setup Wizard screen, select Yes for the Auto-Detect Connection Type, and then click
Next to proceed.
The Setup Wizard detects your ISP configuration. Depending on the type of connection, you

How the Internet Connection Works
Your modem router is now configured to provide 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. You should see the modem router’s Internet LED
blink, indicating communication to the ISP. The browser should begin to display a Web page.

Configuring Your Wireless Network
and Security Settings
This chapter describes how to configure the wireless features of your DGN2000 Wireless-N
ADSL2+ Modem Router.For a wireless connection, the SSID, also called the wireless network
name, and the wireless security setting must be the same for the modem router and wireless
computers or wireless adapters. NETGEAR strongly recommends that you use wireless security.
Warning: Computers can connect wirelessly at a range of several hundred feet. This can
allow others outside of your immediate area to access your network.
This chapter includes:
• “Planning Your Wireless Network”
• “Manually Configuring Your Wireless Network”
• “Manually Configuring Your Wireless Security”
• “Using Push 'N' Connect (WPS) to Configure Your Wireless Network and Security
Planning Your Wireless Network
For compliance and compatibility between similar products in your area, the operating channel
and region must be set correctly.
To configure the wireless network, you can either specify the wireless settings, or you can use
Wi-Fi Protected Setup (WPS) to automatically set the SSID and implement WPA/WPA2 security.
• To manually configure the wireless settings, you must know the following:
– SSID. The default SSID for the modem router is NETGEAR.
– The wireless mode (802.11n, 802.11g, or 802.11b) that each wireless adapter supports.
– W ireless security option. To successfully implement wireless security, check each wireless
adapter to determine which wireless security option it supports.
See “Manually Configuring Your Wireless Security” on page 2-10.

v1.0, July 2008
Wireless-N ADSL2+ Modem Router DGN2000 Reference Manual
• Push 'N' Connect (WPS) automatically implements wireless security on the modem router
while, at the same time, allowing you to automatically implement wireless security on any
WPS-enabled devices (such as wireless computers and wireless adapter cards). You activate
WPS by pressing a WPS button on the modem router, clicking an on-screen WPS button, or
entering a PIN number. This generates a new SSID and implements WPA/WPA2 security.
To set up your wireless network using the WPS feature:
– Use the WPS button on the side of the modem router (there is also an on-screen WPS
button), or enter the PIN of the wireless device.
– Make sure that all wireless computers and wireless adapters on the network are Wi-Fi
certified and WPA or WPA 2 capable, and that they support WPS configuration.
See “Using Push 'N' Connect (WPS) to Configure Your Wireless Network and Security” on
page 2-17.
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 throughput performance, and notebook 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-of-sight 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.

Wireless Security Options
Indoors, computers can connect over 802.11g wireless networks at a maximum range of up to
300 feet. Such distances can allow for others outside your immediate area to access your network.
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 modem router provides highly effective security features, which are
covered in detail in this chapter. Deploy the security features appropriate to your needs.
There are several ways you can enhance the security of your wireless network:
DGN2000
Figure 2-1
There are several ways you can enhance the security of your wireless network:
• Restrict access based on MAC address. You can allow only trusted PCs to connect so that
unknown PCs cannot wirelessly connect to the modem router. Restricting access by MAC
address adds an obstacle against unwanted access to your network, but the data broadcast over
the wireless link is fully exposed (see “Restricting access by MAC address” on page 2-11).
• Turn off the broadcast of the wireless network name SSID. If you disable broadcast of the
SSID, only devices that have the correct SSID can connect. This nullifies wireless network
discovery feature of some products, such as Windows XP, but the data is still exposed (see
“Hiding your wireless network name (SSID)” on page 2-11).

• WEP. Wired Equivalent Privacy (WEP) data encryption provides data security. WEP Shared
Key authentication and WEP data encryption block all but the most determined eavesdropper.
This data encryption mode has been superseded by WPA-PSK and WPA2-PSK (see
“Configuring WEP” on page 2-15).
• WPA-802.1x. Wi-Fi Protected Access (WPA) with user authentication implemented using
IEE 802.1x and RADIUS servers (see “Configuring WPA-802.1x” on page 2-16).
• WPA-PSK (TKIP) + WPA2-PSK (AES). Wi-Fi Protected Access (WPA) using a pre-shared
key to perform authentication and generate the initial data encryption keys. The very strong
authentication along with dynamic per frame re-keying of WPA makes it virtually impossible
to compromise (see “Configuring Mixed WPA-PSK+WPA2-PSK Security” on page 2-13).
Manually Configuring Your Wireless Network
You can view or manually configure the wireless settings and wireless security for the modem
router in the Wireless Settings screen. If you want to make changes, make sure to note the current
settings first. Once you have established basic wireless connectivity, you can enable security
settings appropriate to your needs.
Note: If you use a wireless computer to change the wireless network name (SSID) or
wireless security settings, you will be disconnected when you click Apply. To
avoid this problem, use a computer with a wired connection to access the modem
router.
To manually configure the wireless settings:
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 LAN address and
password you have set up.
2. Select the Wireless Settings in the main menu. The Wireless Settings screen displays.
