1.1 Overview
This chapter introduces the main features and applications of the NBG6815.
The NBG6815 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 NBG6815 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.
CHAPTER 1
Introduction
There are two
or lower) memory sticks, USB hard drives, or USB devices for file sharing. The NBG6815
automatically detects the USB devices.
USB 2.0 ports on the side panel of your NBG6815. You can connect USB (version 2.0
1.2 Applications
Your can have the following networks with the NBG6815:
• W i red. You can connect network devices via the Ethernet ports of the NBG6815 so that they can
communicate with each other and access the Internet.
• W i rele ss. Wireless clients can connect to the NBG6815 to access network resources. You can
use WPS (Wi-Fi Protected Setup) to create an instant network connection with another WPScompatible device.
• W AN. Connect to a broadband modem/router for Internet access.
1.3 Ways to Manage the NBG6815
Use any of the following methods to manage the NBG6815.
• 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 NBG6815.
• Web Configurator. This is recommended for everyday management of the NBG6815 using a
(supported) web browser.

Chapter 1 Introduction
1.4 Good Habits for Managing the NBG6815
Do the following things regularly to make the NBG6815 more secure and to manage the NBG6815
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 NBG6815 to its factory default settings. If you
backed up an earlier configuration file, you would not have to totally re-configure the NBG6815.
You could simply restore your last configuration.
1.5 Resetting the NBG6815
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 NBG6815 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 NBG6815.
3Press the RESET button for longer than five seconds to set the NBG6815 back to its factory-default
configurations.
1.6 The WPS Button
Your NBG6815 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

2.1 Overview
This chapter describes how to access the NBG6815 Web Configurator and provides an overview of
its screens.
The Web Configurator is an HTML-based management interface that allows easy setup and
management of the NBG6815 via Internet browser. Use a browser that supports HTML5, such as
Internet Explorer 9.0 and later versions, Mozilla Firefox 21 and later versions, Safari 6.0 and later
versions or Google Chrome 26.0 and 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.
• JavaScript (enabled by default).
• Java permissions (enabled by default).

2.2 Accessing the Web Configurator
1Make sure your NBG6815 hardware is properly connected and prepare your computer or computer
network to connect to the NBG6815 (refer to the Quick Start Guide).
2Launch your web browser.
3The NBG6815 is in router mode by default. Type "http://192.168.1.1" as the website address. If the
NBG6815 obtains a WAN IP address or a DNS server IP address in the same subnet as the LAN IP
address 192.168.1.1, the default LAN IP address will be changed to 10.0.0.1 automatically. See
Auto-IP Change on page 69 for more information.
If the NBG6815 is in access point, the IP address is 192.168.1.2. See
more information about the modes of the NBG6815.
Your computer must be in the same subnet in order to access this website address.

3.1 Overview
This chapter provides information on the eaZy 123 setup screens in the Web Configurator.
The Web Configurator’s eaZy 123 setup wizard helps you configure your device to access the
Internet. Refer to your ISP for your Internet account information. Leave a field blank if you don’t
have that information.

Launch your web browser and type "http://192.168.1.1" as the website address. Type "1234"
(default) as the password and click Logi n.
eaZy 123 Wizard
Note: The eaZy 123 wizard appears automatically when the NBG6815 is accessed for the
first time or when you reset the NBG6815 to its default factory settings. If you
didn’t configure the wizard screens, you will be redirected to the login page when
you connect to the Internet.
If you have already configured the wizard screens and want to open it again, click on the
upper right corner of any Web Configurator screen. The eaZy 123 wizard attempts to detect which
WAN connection type you are using.
If the eaZy 123 wizard does not detect a connection type, you must select one from the drop-down
list box. Check with your ISP to make sure you use the correct type.
If you do not have the Internet connection, the following screen opens.

3.3.1 WAN Selection Type: Automatic - DHCP
Select the Au t o m a t ic - D HCP option if your ISP did not assign you a fixed IP address.
Figure 9 WAN Selection Type: Automatic - DHCP
3.3.2 WAN Selection 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 NBG6815 (rather than individual computers), the computers
on the LAN do not need PPPoE software installed, since the NBG6815 does that part of the task.
Furthermore, with NAT, all of the LAN's computers will have Internet access.
