1.1 Overview
This chapter introduces the main features and applications of the NBG6616.
The NBG6616 extends the range of your existing wired network without additional wiring, providing
easy network access to mobile users. You can set up a wireless network with other IEEE 802.11a/b/
g/n/ac compatible devices. The NBG6616 is able to function both 2.4GHz and 5GHz networks at the
same time.
A range of services such as a firewall and content filtering are also available for secure Internet
computing.
There are two USB 2.0 ports on the side panel of your NBG6616. You can connect USB (version 2.0
or lower) memory sticks, USB hard drives, or USB devices for file sharing. The NBG6616
automatically detects the USB devices.
CHAPTER 1
Introduction
Note: For the USB function, it is strongly recommended to use version 2.0 or lower USB
storage devices (such as memory sticks, USB hard drives) and/or USB devices.
Other USB products are not guaranteed to function properly with the NBG6616.
1.2 Applications
Your can have the following networks with the NBG6616:
• Wired. You can connect network devices via the Ethernet ports of the NBG6616 so that they can
communicate with each other and access the Internet.
• Wireless. Wireless clients can connect to the NBG6616 to access network resources. You can
use WPS (Wi-Fi Protected Setup) to create an instant network connection with another WPScompatible device.
• WAN. Connect to a broadband modem/router for Internet access.
1.3 Ways to Manage the NBG6616
Use any of the following methods to manage the NBG6616.
• WPS (Wi-Fi Protected Setup). You can use the WPS button or the WPS section of the Web
Configurator to set up a wireless network with your NBG6616.
• Web Configurator. This is recommended for everyday management of the NBG6616 using a
(supported) web browser.
NBG6616 User’s Guide

Chapter 1 Introduction
1.4 Good Habits for Managing the NBG6616
Do the following things regularly to make the NBG6616 more secure and to manage the NBG6616
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 NBG6616 to its factory default settings. If you
backed up an earlier configuration file, you would not have to totally re-configure the NBG6616.
You could simply restore your last configuration.
1.5 Resetting the NBG6616
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 NBG6616 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”.
1.5.1 How to Use the RESET Button
1Make sure the power LED is on.
2Press the RESET button for one to four seconds to restart/reboot the NBG6616.
3Press the RESET button for longer than five seconds to set the NBG6616 back to its factory-default
configurations.
1.6 The WPS Button
Your NBG6616 supports Wi-Fi Protected Setup (WPS), which is an easy way to set up a secure
wireless network. WPS is an industry standard specification, defined by the Wi-Fi Alliance.
WPS allows you to quickly set up a wireless network with strong security, without having to
configure security settings manually. Each WPS connection works between two devices. Both
devices must support WPS (check each device’s documentation to make sure).
Depending on the devices you have, you can either press a button (on the device itself, or in its
configuration utility) or enter a PIN (a unique Personal Identification Number that allows one device
to authenticate the other) in each of the two devices. When WPS is activated on a device, it has two
minutes to find another device that also has WPS activated. Then, the two devices connect and set
up a secure network by themselves.
You can use the WPS button () on the front panel of the NBG6616 to activate WPS in order to
quickly set up a wireless network with strong security.

Chapter 3 Connection Wizard
3.3.2 Connection Type: PPPoE
Point-to-Point Protocol over Ethernet (PPPoE) functions as a dial-up connection. PPPoE is an IETF
(Internet Engineering Task Force) standard specifying how a host personal computer interacts with
a broadband modem (for example DSL, cable, wireless, etc.) to achieve access to high-speed data
networks.
For the service provider, PPPoE offers an access and authentication method that works with existing
access control systems (for instance, RADIUS).
One of the benefits of PPPoE is the ability to let end users access one of multiple network services,
a function known as dynamic service selection. This enables the service provider to easily create
and offer new IP services for specific users.
Operationally, PPPoE saves significant effort for both the subscriber and the ISP/carrier, as it
requires no specific configuration of the broadband modem at the subscriber's site.
By implementing PPPoE directly on the NBG6616 (rather than individual computers), the computers
on the LAN do not need PPPoE software installed, since the NBG6616 does that part of the task.
Furthermore, with NAT, all of the LAN's computers will have Internet access.
