N300 Wireless ADSL2+ Modem Router DGN2200Mv2
The following table describes the Basic Settings screen fields and options.
Settings Description
Does Your ISP Require a Login? • Yes
• No
These fields
appearonly ifno
login is required.
Account Name
(If required) Enter the account name provided by your ISP. This might also be called the host name.
Domain Name
(If required) Enter the domain name provided by your ISP.
These fields
appear only if
your ISP
requires a login.
Login The login name provided by your ISP. This is often an e-mail address.
Password The password that you use to log in to your ISP.
Service Name If your ISP provided a service name, enter it here.
Idle Timeout (In
minutes) If you want to change the Internet login time-out, enter a new value in minutes. This determines how long the wireless modem router keeps the
Internet connection active after there is no Internet activity from the LAN.
Entering an Idle Timeout value of 0 (zero) means never log out.
Internet IP Address • Get Dynamically from ISP. Your ISP uses DHCP to assign your IP
address. Your ISP automatically assigns these addresses.
• Use Static IP Address. Enter the IP address that your ISP assigned.
Also enter the IP subnet mask and the gateway IP address. The gateway
is the ISP’s wireless modem router to which your wireless modem router
will connect.

Internet Configuration
16
N300 Wireless ADSL2+ Modem Router DGN2200Mv2
ADSL Settings
For information about how to install ADSL filters, see the Setup Manual.
NETGEAR recommends that you use the Setup Wizard to automatically detect and configure
your ADSL settings. This usually works fine. However, if you have technical experience and
are sure of the multiplexing method and virtual circuit number for the virtual path identifier
(VPI) and virtual channel identifier (VCI), you can specify those settings here.
Note: Use the Setup Wizard to select the correct country to optimize
detection of the ADSL settings.
NAT (Network Address
Translation) NAT automatically assigns private IP addresses (10.0.0.x) to devices on your LAN.
• Enable. Usually NAT is enabled.
• Disable. This disables NAT, but leaves the firewall active. Disable NAT
only if you are sure that you do not require it. When NAT is disabled, only
standard routing is performed by this router. Classical routing lets you
directly manage the IP addresses that the wireless modem router uses.
Classical routing should be selected only by experienced users.1
• Advanced users can also bridge or disable the firewall.
Router MAC Address Your computer’s local address is its unique address on your network. This is
also referred to as the computer’s MAC (Media Access Control) address.
• Use Default MAC Address. This is the usual setting.
• Use Computer MAC address. If your ISP requires MAC authentication,
you can use this setting to disguise the wireless modem router’s MAC
address with the computer’s own MAC address.
• Use This MAC Address. If your ISP requires MAC authentication, you
can manually type the MAC address for a different computer. The format
for the MAC address is XX:XX:XX:XX:XX:XX.
1. Disabling NAT reboots the wireless modem router and resets its configuration settings to the factory defaults.
Disable NAT only if you plan to install the wireless modem router in a setting where you will be manually
administering the IP address space on the LAN side of the router.

2. Wireless Network Configuration
For a wireless connection, the SSID, also called the wireless network name, and the wireless
security settings must be the same for the wireless modem router and wireless computers or
wireless adapters. NETGEAR strongly recommends that you use wireless security.
Note: Computers can connect wirelessly at a range of hundreds of
meters. If you do not use wireless security, this can allow others
outside your immediate area to access your network.

Wireless Network Configuration
19
N300 Wireless ADSL2+ Modem Router DGN2200Mv2
Preset Wireless Security
The wireless modem router comes with preset security. This means that the Wi-Fi network
name (SSID), passphrase, and security option (encryption protocol) are preset in the factory.
You can find the preset SSID and passphrase on the bottom of the unit.
• Wi-Fi network name (SSID) identifies your network so devices can find it.
• Passphrase controls access to your network. Devices that know the SSID and the
passphrase can find your wireless network and connect.
Note: The preset SSID and passphrase are uniquely generated for every
device to protect and maximize your wireless security.
• Security option is the type of security protocol applied to your wireless network. The
security protocol in force encrypts data transmissions and ensures that only trusted
devices receive authorization to connect to your network. The preset security option is
WPA-PSK/WPA2-PSK mixed mode, described in Wireless Security Options on page 20.
The Wireless Settings screen lets you view and change the preset security settings.
However, NETGEAR recommends that you not change your preset security settings. If
you do decide to change your preset security settings, make a note of the new settings and
store it in a safe place where you can easily find it.

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, have the following information on hand:
-SSID. The default SSID for the wireless modem router is printed on the label on the
bottom of the unit.
-The wireless mode (80.211n, 802.11g, or 802.11b) that each wireless adapter
supports.
-Wireless security option. To successfully implement wireless security, check each
wireless adapter to determine which wireless security option it supports.
See Manually Configure Wireless Settings on page 22.

• Push 'N' Connect (WPS) implements WPA/WPA2 wireless security on the wireless
modem router and your wireless computer or device at the same time. The wireless
computer or device must be compatible with WPS.
See Push 'N' Connect (WPS) Method on page 28.
Wireless Placement and Range Guidelines
The range of your wireless connection can vary significantly based on the physical placement
of the wireless 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 wireless 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 100 meters (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 N300 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:
• Restrict access based on MAC address. You can allow only trusted PCs to connect so
that unknown PCs cannot wirelessly connect to the wireless 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.
