Tips for Reading User’s Guides On-Screen
When reading a ZyXEL User’s Guide On-Screen, keep the following in mind:
• If you don’t already have the latest version of Adobe Reader, you can download
it from http://www.adobe.com.
• Use the PDF’s bookmarks to quickly navigate to the areas that interest you.
Adobe Reader’s bookmarks pane opens by default in all ZyXEL User’s Guide

view, you can enter a number in the toolbar in Reader, then press [ENTER] to

phrase. This can help you quickly pinpoint the information you require. You can
also enter text directly into the toolbar in Reader.
• To quickly move around within a page, press the [SPACE] bar. This turns your
cursor into a “hand” with which you can grab the page and move it around freely
on your screen.

1.3 Ways to Manage the NBG4615
Use any of the following methods to manage the NBG4615.
• 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 ZyXEL Device.
• Web Configurator. This is recommended for everyday management of the
NBG4615 using a (supported) web browser.
1.4 Good Habits for Managing the NBG4615
Do the following things regularly to make the NBG4615 more secure and to
manage the NBG4615 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
NBG4615 to its factory default settings. If you backed up an earlier
configuration file, you would not have to totally re-configure the NBG4615. You
could simply restore your last configuration.

CHAPTER 2
The WPS Button
2.1 Overview
Your NBG4615 supports WiFi Protected Setup (WPS), which is an easy way to set
up a secure wireless network. WPS is an industry standard specification, defined
by the WiFi 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.
For more information on using WPS, see Section 13.2 on page 111.

extremely important because without it, you must know the IP
address of a computer before you can access it. The NBG4615
uses a system DNS server (in the order you specify here) to
resolve domain names for DDNS and the time server.

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 NBG4615 (rather than individual
computers), the computers on the LAN do not need PPPoE software installed,
since the NBG4615 does that part of the task. Furthermore, with NAT, all of the
LAN's computers will have Internet access.

CHAPTER 11
Universal Repeater Mode
11.1 Overview
In universal repeater mode, your NBG4615 can act as an access point and
wireless client at the same time. The NBG4615 can connect to an existing network
through another access point and also lets wireless clients connect to the network
through it. This helps you expand wireless coverage when you have an access
point or wireless router already in your network.
In the example below, the NBG4615 (A) is configured as a universal repeater. It
has three clients that want to connect to the Internet. The NBG4615 wirelessly
connects to the available access point (B).
Figure 54 Universal Repeater Mode
After the NBG4615 and the access point connect, the NBG4615 acquires its IP
address from the access point. The clients of the NBG4615 can now surf the
Internet.
11.2 What You Can Do
•Use the Status screen to view read-only information about your NBG4615
(Section 11.5 on page 92).
•Use the LAN screen to set the IP address for your NBG4615 acting as an access
point (Section 10.5 on page 86).
•Use the Universal Repeater screen to configure the security between the
NBG4615 and another access point (Section 11.6 on page 94).

12.1 Overview
Your NBG4615 can act as a wireless client. In wireless client mode, it can connect
to an existing network via an access point. Use this mode if you already have an
access point or router in your network.
In the example below, one NBG4615 (A) is configured as a wireless client and
another is used as an access point (B). The wireless client has two clients that
need to connect to the Internet. The NBG4615 wirelessly connects to the available
access point (B).
Figure 62 Wireless Client Mode
After the NBG4615 and the access point connect, the NBG4615 acquires its WAN
IP address from the access point. The clients of the NBG4615 can now surf the
Internet.
12.2 What You Can Do
•Use the Status screen to view read-only information about your NBG4615
(Section 12.4 on page 101).
•Use the LAN screen to set the IP address for your NBG4615 acting as an access
point (Section 10.5 on page 86).
•Use the Wireless LAN screen to associate your NBG4615 (acting as a wireless
client) with an existing access point (Section 12.5 on page 104).

Tutorials
13.1 Overview
This chapter provides tutorials for setting up your NBG4615.
•Set Up a Wireless Network with WPS
•Configure Wireless Security without WPS
•Using Multiple SSIDs on the NBG4615
•Connecting the NBG4615 (in Universal Repeater Mode) to an AP or Wireless
Router
13.2 Set Up a Wireless Network with WPS
This section gives you an example of how to set up wireless network using WPS.
This example uses the NBG4615 as the AP and NWD210N as the wireless client
which connects to a notebook.
Note: The wireless client must be a WPS-aware device (for example, a WPS USB
adapter or PCI card).
There are two WPS methods for creating a secure connection. This tutorial shows
you how to do both.
•Push Button Configuration (PBC) - create a secure wireless network simply
by pressing a button. See Section 13.2.1 on page 112.This is the easier method.
•PIN Configuration - create a secure wireless network simply by entering a
wireless client's PIN (Personal Identification Number) in the NBG4615’s
interface. See Section 13.2.2 on page 113. This is the more secure method,
since one device can authenticate the other.
Chapter 13 Tutorials
NBG4615 User’s Guide
112
13.2.1 Push Button Configuration (PBC)
1Make sure that your NBG4615 is turned on. Make sure the WLAN switch (at the
back panel of the NBG4615) is set to ON, and that the device is placed within
range of your computer.
2Make sure that you have installed the wireless client (this example uses the
NWD210N) driver and utility in your notebook.
3In the wireless client utility, find the WPS settings. Enable WPS and press the WPS
button (Start or WPS button)
4Log into NBG4615’s Web Configurator and press the Push Button in the
Configuration > Network > Wireless Client > WPS Station screen.
Note: Your NBG4615 has a WPS button located on its back panel, as well as a WPS
button in its configuration utility. Both buttons have exactly the same function;
you can use one or the other.
Note: It doesn’t matter which button is pressed first. You must press the second
button within two minutes of pressing the first one.
The NBG4615 sends the proper configuration settings to the wireless client. This
may take up to two minutes. Then the wireless client is able to communicate with
the NBG4615 securely.

NBG4615 User’s Guide 113
The following figure shows you an example to set up wireless network and security
by pressing a button on both NBG4615 and wireless client (the NWD210N in this
example).
Figure 72 Example WPS Process: PBC Method
13.2.2 PIN Configuration
When you use the PIN configuration method, you need to use both NBG4615’s
configuration interface and the client’s utilities.
1Launch your wireless client’s configuration utility. Go to the WPS settings and
select the PIN method to get a PIN number.
2Enter the PIN number to the PIN field in the Configuration > Network >
Wireless LAN > WPS Station screen on the NBG4615.
3Click Start buttons (or button next to the PIN field) on both the wireless client
utility screen and the NBG4615’s WPS Station screen within two minutes.

13.3.1 Configure Your Notebook
Note: We use the ZyXEL M-302 wireless adapter utility screens as an example for the
wireless client. The screens may vary for different models.
1The NBG4615 supports IEEE 802.11b, IEEE 802.11g and IEEE 802.11n wireless
clients. Make sure that your notebook or computer’s wireless adapter supports
one of these standards.
2Wireless adapters come with software sometimes called a “utility” that you install
on your computer. See your wireless adapter’s User’s Guide for information on
how to do that.
3After you’ve installed the utility, open it. If you cannot see your utility’s icon on
your screen, go to Start > Programs and click on your utility in the list of

this User’s Guide.
If your connection is successful, open your Internet browser and enter http://
www.zyxel.com or the URL of any other web site in the address bar. If you are able
to access the web site, your wireless connection is successfully configured.
13.4 Using Multiple SSIDs on the NBG4615
You can configure more than one SSID on a NBG4615 when it is operating in
access point or universal repeater mode. This allows you to configure multiple
independent wireless networks on the NBG4615 as if there were multiple APs
(virtual APs). Each virtual AP has its own SSID, wireless security type and MAC
filtering settings. That is, each SSID on the NBG4615 represents a different access
point/wireless network to wireless clients in the network.
Clients can associate only with the SSIDs for which they have the correct security
settings. Clients using different SSIDs can access the Internet and the wired
network behind the NBG4615 (such as a printer). You can allow communication
between wireless clients of different SSIDs in the Network > Wireless LAN > General
screen. See Section 14.2 on page 133 for more information.
Chapter 13 Tutorials
NBG4615 User’s Guide 119
For example, you may set up three wireless networks (A, B and C) in your office.
A is for workers, B is for guests and C is specific to a VoIP device in the meeting
room.
13.4.1 Configuring Security Settings of Multiple SSIDs
The NBG4615 is in access point mode by default. If you want to use multiple
SSIDs when the NBG4615 is in universal repeater mode, see Chapter 8 on page
81 for how to set the NBG4615 to universal repeater mode.
This example shows you how to configure the SSIDs with the following parameters
on your NBG4615 (in access point mode).
1Connect your computer to the LAN port of the NBG4615 using an Ethernet cable.
2The default IP address of the NBG4615 is “192.168.1.2”. In this case, your
