This chapter introduces the main features and applications of the NBG6604.
The NBG6604 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 NBG6604 is able to function both 2.4GHz and 5GHz networks at the same time.
A range of services such as a firewall are also available for secure Internet computing.
1.2 Applications
CHAPTER 1
Introduction
You can have the following networks with the NBG6604:
• Wired. You can connect network devices via the Ethernet ports of the NBG6604 so that they can
communicate with each other and access the Internet.
• Wireless. Wireless clients can connect to the NBG6604 to access network resources. You can use WPS
(Wi-Fi Protected Setup) to create an instant network connection with another WPS-compatible
device.
• WAN. Connect to a broadband modem/router for Internet access.
1.3 Ways to Manage the NBG6604
Use any of the following methods to manage the NBG6604:
• 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 NBG6604.
• Web Configurator. This is recommended for everyday management of the NBG6604 using a
(supported) web browser.
• Zyxel ONE Connect App. See Section 12.3 on page 85.
1.4 Good Habits for Managing the NBG6604
Do the following things regularly to make the NBG6604 more secure and to manage the NBG6604 more
effectively.
NBG6604 User’s Guide

Chapter 1 Introduction
• 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 NBG6604 to its factory default settings. If you backed up an
earlier configuration file, you would not have to totally re-configure the NBG6604. You could simply
restore your last configuration.
1.5 Resetting the NBG6604
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 NBG6604 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 NBG6604.
3Press the RESET button for longer than five seconds to set the NBG6604 back to its factory-default
configurations.
1.6 The WPS Button
Your NBG6604 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 top panel of the NBG6604 to activate WPS in order to
quickly set up a wireless network with strong security.
1Make sure the power LED is on (not blinking).
2Press the WPSbutton for more than three seconds and release it. Press the WPS button on another WPS-
enabled device within range of the NBG6604.

2.1 Overview
This chapter describes how to access the NBG6604 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 NBG6604 via Internet browser. Use a browser that supports HTML5, such asInternet
Explorer 11.0 and later versions, Mozilla Firefox 50 and later versions, Safari 10.0 and later versions, Edge
14 and later versions or Google Chrome 54 and later versions. The recommended screen resolution is
1024 by 768 pixels.
CHAPTER 2
Introducing the Web
Configurator
In order to use the Web Configurator you need to allow:
• JavaScript (enabled by default).
• Java permissions (enabled by default).
Refer to the Troubleshooting chapter (Chapter 15 on page 101) to see how to make sure these functions
are allowed in Internet Explorer.
2.2 Accessing the Web Configurator
1Make sure your NBG6604 hardware is properly connected and prepare your computer or computer
network to connect to the NBG6604 (refer to the Quick Start Guide).
2Launch your web browser.
3The NBG6604 is in router mode by default. Type "http://myrouter" as the website address. If the NBG6604
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
on page 52 for more information.
If the NBG6604 is in access point mode, the IP address will be 192.168.1.2. See Chapter 4 on page 25 for
more information about the modes of the NBG6604.

eaZy 123 Wizard
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.
3.2 Accessing the eaZy 123 Wizard
Launch your web browser and type "http://myrouter" as the website address. Type "1234" (default) as
the password and click Login.
CHAPTER 3
Note: The eaZy 123 wizard appears automatically when the NBG6604 is accessed for the first
time or when you reset the NBG6604 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 Internet Type
The NBG6604 offers three WAN selection types. They are : Automatic - DHCP, PPPoE, and Static.
Configure the Internet type settings on your NBG6604 in the first part. The following screen depends on
your Internet connection type. Enter the details provided by your Internet Service Provider (ISP) in the
fields (if any).
Check with your ISP to make sure you use the correct type. This wizard screen varies according to the
connection type that you select.
3.3.1 WAN Selection Type: Automatic - DHCP
Select the Automatic - DHCP 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.
NBG6604 User’s Guide
20
Chapter 3 eaZy 123 Wizard
By implementing PPPoE directly on the NBG6604 (rather than individual computers), the computers on
the LAN do not need PPPoE software installed, since the NBG6604 does that part of the task.
Furthermore, with NAT, all of the LAN's computers will have Internet access.
