CHAPTER 1
Getting to Know Your NBG334W
This chapter introduces the main features and applications of the NBG334W.
1.1 Overview
The NBG334W acts as either an access point (AP) or a secure broadband router for all data
passing between the Internet and your local network. In both AP and Router Mode you can
set up a wireless network with other IEEE 802.11b/g compatible devices. In Router Mode a
number of services such as a firewall and content filtering are also available. You can use
media bandwidth management to efficiently manage traffic on your network. Bandwidth
management features allow you to prioritize time-sensitive or highly important applications
such as Voice over the Internet (VoIP).
1.2 AP Mode
Select AP Mode if you already have a router or gateway on your network which provides
network services such as a firewall or bandwidth management.
The following figure shows computers in a WLAN connecting to the NBG334W, which acts
as an access point (A). The NBG334W allows the wireless computers to share the same
Internet access as the other computers connected to the router (B) on the same network.
Figure 1 Wireless Internet Access in AP Mode

1.3 Router Mode
Select Router Mode if you need to route traffic between your network and another network
such as the Internet, and require important network services such as a firewall or bandwidth
management.
The following figure shows computers in a WLAN connecting to the NBG334W (A), which
has a DSL connection to the Internet. The NBG334W is set to Router Mode and has router
features such as a built-in firewall (B).
Figure 2 Secure Wireless Internet Access in Router Mode
1.4 Router Features vs. AP Features
The following table shows which features are available in Router or AP Mode.
AB
Table 1 Features Available in Router Mode vs. AP Mode
FEATURE ROUTER MODE AP MODE
DHCP
This allows individual clients to obtain IP addresses at start-
up from a DHCP server.
YES NO
Firewall
This establishes a network security barrier, protecting your
network from attacks and controlling access between your
network and the Internet.
YES NO
Bandwidth Management
This allows you to allocate network bandwidth to specific
applications and or subnets.
YES NO
Any IP
This allows a computer to access the NBG334W when the
IP addresses of the computer and the NBG334W are not in
the same subnet.)
YES NO
Wireless
This allows two or more devices to communicate without
wires, based on IEEE 802.11 wireless standards.
YES YES
Chapter 1 Getting to Know Your NBG334W
NBG334W User’s Guide 31
1.5 Ways to Manage the NBG334W
Use any of the following methods to manage the NBG334W.
• Web Configurator. This is recommended for everyday management of the NBG334W
using a (supported) web browser.
• Command Line Interface. Line commands are mostly used for troubleshooting by service
engineers.
• FTP. Use File Transfer Protocol for firmware upgrades and configuration backup/restore.
1.6 Good Habits for Managing the NBG334W
Do the following things regularly to make the NBG334W more secure and to manage the
NBG334W more effectively.
• Change the password. Use a password that’s not easy to guess and that consists of
different types of characters, such as numbers and letters.
• Write down the password and put it in a safe place.
• Back up the configuration (and make sure you know how to restore it). Restoring an
earlier working configuration may be useful if the device becomes unstable or even
crashes. If you forget your password, you will have to reset the NBG334W to its factory
default settings. If you backed up an earlier configuration file, you would not have to
totally re-configure the NBG334W. You could simply restore your last configuration.

CHAPTER 2
Introducing the Web
Configurator
This chapter describes how to access the NBG334W web configurator and provides an
overview of its screens.
2.1 Web Configurator Overview
The web configurator is an HTML-based management interface that allows easy setup and
management of the NBG334W via Internet browser. Use Internet Explorer 6.0 and later or
Netscape Navigator 7.0 and later versions or Safari 2.0 or later versions. The recommended
screen resolution is 1024 by 768 pixels.
In order to use the web configurator you need to allow:
• Web browser pop-up windows from your device. Web pop-up blocking is enabled by
default in Windows XP SP (Service Pack) 2.
• JavaScripts (enabled by default).
• Java permissions (enabled by default).
Refer to the Troubleshooting chapter to see how to make sure these functions are allowed in
Internet Explorer.
2.2 Accessing the Web Configurator
1Make sure your NBG334W hardware is properly connected and prepare your computer
or computer network to connect to the NBG334W (refer to the Quick Start Guide).
2Launch your web browser.
3Type "http://192.168.1.1" as the website address.
Your computer must be in the same subnet in order to access this website address.
•In Router Mode enable the DHCP Server. The NBG334W assigns your computer an IP
address on the same subnet.
•In AP Mode the NBG334W does not assign an IP address to your computer, so you
should check it’s in the same subnet. See Section 4.5 on page 66 for more information.
Chapter 2 Introducing the Web Configurator
NBG334W User’s Guide

4Type "1234" (default) as the password and click Login. In some versions, the default
password appears automatically - if this is the case, click Login.
5You should see a screen asking you to change your password (highly recommended) as
shown next. Type a new password (and retype it to confirm) and click Apply or click
Ignore.
Figure 4 Change Password Screen
"The management session automatically times out when the time period set in
the Administrator Inactivity Timer field expires (default five minutes). Simply
log back into the NBG334W if this happens.
6Select the setup mode you want to use.
• Click Go to Wizard Setup to use the Configuration Wizard for basic Internet and
Wireless setup.
• Click Go to Basic Setup if you want to view and configure basic settings that are not part
of the wizard setup. Not all Web Configurator screens are available in this mode. See
Chapter 21 on page 197 for more information.
7Click Go to Advanced Setup to view and configure all the NBG334W’s settings.
Chapter 2 Introducing the Web Configurator
NBG334W User’s Guide 35
2.3 Resetting the NBG334W
If you forget your password or IP address, or you cannot access the web configurator, you will
need to use the RESET button at the back of the NBG334W to reload the factory-default
configuration file. This means that you will lose all configurations that you had previously
saved, the password will be reset to “1234” and the IP address will be reset to “192.168.1.1”.
2.3.1 Procedure to Use the Reset Button
1Make sure the power LED is on.
2Press the RESET button for five seconds or until the power LED begins to blink and
then release it. When the power LED begins to blink, the defaults have been restored and
the NBG334W restarts.
2.4 Navigating the Web Configurator
The following summarizes how to navigate the web configurator from the Status screen in
Router Mode and AP Mode.
2.5 The Status Screen in Router Mode
Click on Status. The screen below shows the status screen in Router Mode.

2.5.4 Summary: DHCP Table
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual
clients to obtain TCP/IP configuration at start-up from a server. You can configure the
NBG334W as a DHCP server or disable it. When configured as a server, the NBG334W
provides the TCP/IP configuration for the clients. If DHCP service is disabled, you must have
another DHCP server on your LAN, or else the computer must be manually configured.
Click the DHCP Table (Details...) hyperlink in the Status screen. Read-only information here
relates to your DHCP status. The DHCP table shows current DHCP client information
(including IP Address, Host Name and MAC Address) of all network clients using the
NBG334W’s DHCP server.
