Overview
The NBG420N is an IEEE 802.11b/g/n wireless broadband router or access point (AP). As
a router, the NBG420N directs traffic between your wireless network and another network
such as the Internet as shown below, providing services such as content filtering,
bandwidth management and a firewall.
This Quick Start Guide shows you how to do the following with your NBG420N in router
mode:
1Connecting Your Hardware
2Accessing the Web Configurator
3Connecting to the Internet with the Wizard
4Set Up a Wireless Network Manually or with WPS
See your User’s Guide on the CD in the package on how to set up the NBG420N as an AP
and for more information on all features.
To read the User’s Guide insert the CD that came in the box into your CD-ROM drive. A
screen should pop up. Navigate to the User’s Guide from this screen. If a screen does not
pop up, open Windows Explorer (click My Computer), click on the CD-ROM drive (usually
drive D:) and navigate to it from there.

The LEDs
Look at the LEDs (lights). When you connect the power, the power LED ( ) blinks and
stays on once the device is ready.
The LAN ( ) and WAN ( ) LEDs turn on if the corresponding connections
are properly made.
VIf an LED does not turn on, check your connections. If this doesn’t help,
disconnect the NBG420N from its power source, wait for a few seconds and
turn it back on.
2 Accessing the Web Configurator
Default Login Information
1Launch an Internet browser such as Internet Explorer. Enter “http://192.168.1.1” as
shown below.

2The Password window displays. Enter the password (“1234” is the default) and click
Login.
VIf the login screen does not display, make sure your computer is set to
receive an IP address dynamically. If that doesn’t help, check your web
browser’s security settings (see the appendix in the User’s Guide for
information on both suggestions).
3Change the password in the screen that follows and click Apply.
4Click Go to Wizard setup to set up your NBG420N for the first time

Configure your NBG420N to support a wireless network by following these steps.
1Enter a unique Name (SSID) to identify the NBG420N on the wireless LAN.
2Select Auto to automatically use WPA-PSK which provides a high level of security. See
your User’s Guide for information on other kinds of security. Click Next.

ENGLISH

3Write down the security key that displays in the pop-up screen. Computers on the wireless
network will need this security key to access the NBG420N. The security key is case-
sensitive so “ABCD” is not the same as “abcd”.
"Write down the security key, Name (SSID), Security and Channel
Selection for later use as the NBG420N and other devices on your wireless
network must use the same settings.
4Click OK to continue.
3.3 WAN Connection
You may need to wait several minutes while the wizard attempts to detect which WAN
connection type (Ethernet, PPP over Ethernet or PPTP) you are using.
• If the wizard detects your connection type, follow the steps for your connection type as
given below.
• If the wizard cannot detect a connection type, you must select your connection type from
the drop-down list box in the screen below. If you do not know what connection type to use,
check with your Internet Service Provider (ISP).
"If you were given Internet access settings, type them in the following fields.
Otherwise leave the default settings and click Next.

ENGLISH

address given by your ISP.
If you were given DNS server settings, type them in the fields. Otherwise leave the default
settings and click Next.
3.5 WAN MAC Address
A MAC address is a number which uniquely identifies a device on any network. Set the
WAN port’s MAC address by either using your device’s factory assigned default MAC
address or cloning the MAC address of a computer on your LAN. By default, the NBG420N
uses the factory assigned MAC address to identify itself on the WAN.

ENGLISH
10
•SelectFactory Default to use the factory-assigned, default MAC address.
•SelectClone the Computer’s MAC Address to clone the MAC address from a computer
on your LAN. Type the IP address of the computer with the MAC address you are cloning. It
is advisable to clone the MAC address from a computer on your LAN even if your ISP does
not presently require MAC address authentication.
•SelectSet WAN MAC Address if you know the MAC address you want to use.
3.6 Bandwidth Management
Select Enable BM for all traffic automatically to have the NBG420N prioritize data traffic
according to the its use. For example, video streaming may have higher priority than email.
Leave unchecked if unsure. Click Next.
3.7 Setup Complete
1Click Apply to save your changes in the next screen that appears in the wizard.
2Click Finish in the screen below to complete the wizard setup.
3Congratulations. Open a web browser, such as Internet Explorer, to visit your favorite
website.

ENGLISH
11
VIf you cannot access the Internet when your computer is connected to one
of the NBG420N’s LAN ports, check your connections. Then turn the
NBG420N off, wait for a few seconds and turn it back on. If this doesn’t
work run the wizard again, making sure you type the information correctly.
Also, if you are using a new Internet account, contact your ISP to make
sure it is active. See Troubleshooting in the User’s Guide for more
suggestions.
4 Set Up a Wireless Network
You can use Wi-Fi Protected Setup (WPS) to add wireless devices to your wireless
network. The other wireless devices must also support WPS.
If your wireless devices display the WPS logo as shown, go to
section 4.1 to use WPS to set up your wireless network.
If your wireless devices do not display the WPS logo, go to section
4.2 to manually set up a wireless network.
4.1 Set up Your Wireless Network with WPS
Follow these steps to set up your wireless network using WPS.
1Place a WPS-enabled device within range of the NBG420N.

ENGLISH
12
2Press the WPS button on both devices. It doesn’t matter which button is pressed first.
You must press the second button within two minutes of pressing the first one.
"Your NBG420N has a WPS button located on its housing, as well as a WPS
button available in the web configurator used to manage the NBG420N.
Other WPS-enabled devices should have at least one similar WPS button.
3The WPS LED ( ) on the NBG420N blinks for a few seconds, then shines steadily.
4Check if your devices are connected by trying to connect to the Internet using the
device you connected to the NBG420N. If you can do this, then your WPS connection is
successful.
5To add another WPS enabled device to your wireless network, press the WPS buttons
on your NBG420N and your next WPS-enabled device.
Congratulations! You are now ready to connect to the Internet wirelessly through your
NBG420N.
