Introduction
1.1 Overview
The NBG-416N extends the range of your existing wired network without
additional wiring, providing easy network access to mobile users.
Your can create the following connections using the NBG-416N:
• LAN. You can connect network devices via the Ethernet ports of the NBG-416N
so that they can communicate with each other and access the Internet.
• WLAN. Wireless clients can connect to the NBG-416N to access network
resources.
• WAN. Connect to a broadband modem/router for Internet access.
Figure 1 NBG-416N Network
You can set up the NBG-416N with other IEEE 802.11b/g/n compatible devices in
one of the following device modes:
•Router
• Access Point
• Universal Repeater
• Client Bridge
NBG-416N User’s Guide

Chapter 1 Introduct ion
Use a (supported) web browser to manage the NBG-416N. Menus vary according
to which mode you’re using.
Router Mode Non-Router Mode
See Chapter 4 on page 37 for more information on these modes.
1.2 Securing the NBG-416N
Do the following things regularly to make the NBG-416N more secure and to
manage the NBG-416N 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
NBG-416N to its factory default settings. If you backed up an earlier
configuration file, you would not have to totally re-configure the NBG-416N. You
could simply restore your last configuration.

1.4 The WPS Button
Your NBG-416N 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
(recommended) 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 5.2.1 on page 61.
1.5 W all Mounting
You may need screw anchors if mounting on a concrete or brick wall.
Table 2 Wall Mounting Information
Distance between holes 12 cm
M4 Screws Two
Screw anchors (optional) Two
1 Select a position free of obstructions on a wall strong enough to hold the weight of
the device.
2 Mark two holes on the wall at the appropriate distance apart for the screws.
Be careful to avoid damaging pipes or cables located inside the
wall when drilling holes for the screws.
3 If using screw anchors, drill two holes for the screw anchors into the wall. Push the
anchors into the full depth of the holes, then insert the screws into the anchors.
Do not insert the screws all the way in - leave a small gap of about 0.5 cm.
If not using screw anchors, use a screwdriver to insert the screws into the wall. Do
not insert the screws all the way in - leave a gap of about 0.5 cm.

CHAPTER 2
The Web Configurator
2.1 Overview
This chapter describes how to access the NBG-416N 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 NBG-416N via Internet browser. Use Internet
Explorer 6.0 and later versions, Mozilla Firefox 3 and later versions, or Safari 2.0
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).
Refer to Chapter 20 Troubleshooting to see how to make sure these functions are
allowed in Internet Explorer.
2.2 Accessing the Web Configurator
1 Make sure your NBG-416N hardware is properly connected and prepare your
computer or computer network to connect to the NBG-416N (refer to the Quick
Start Guide).
2 Launch your web browser.
3 Type "http://192.168.1.1" as the website address in your web browser. This is the
default LAN IP address in router mode, the default device mode (192.168.1.2 is
the default IP address in non-router mode).
Your computer must be in the same subnet in order to access this website
address. In router mode, the NBG-416N can assign your computer an IP address,
NBG-416N User’s Guide
19
Page 20
Chapter 2 The Web Configurator
so you must set your computer to get an IP address automatically (computer
factory default) or give it a fixed IP address in the range between 192.168.1.3 and
192.168.1.254 (see the appendices).
4 Type admin (default) as the user name and 1234 (default) as the password and
click OK.

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 NBG-416N
to reload the factory-default configuration file. This means that you will lose all
configurations that you had previously saved, the username will be reset to
admin and password will be reset to 1234. The IP address will be reset to
“192.168.1.1”.
2.3.1 Using the RESET Button
1 Make sure the power LED is on.
2 Press the RESET button for longer than 1 second to restart/reboot the NBG-416N.

28
NBG-416N User’s Guide

Chapter 3 Connection Wizard
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 NBG-416N (rather than individual
computers), the computers on the LAN do not need PPPoE software installed,
since the NBG-416N does that part of the task. Furthermore, with NAT, all of the
LAN's computers will have Internet access.

3.4.5 WAN IP Address Assignment
Every computer on the Internet must have a unique IP address. If your networks
are isolated from the Internet, for instance, only between your two branch offices,
you can assign any IP addresses to the hosts without problems. However, the
Internet Assigned Numbers Authority (IANA) has reserved the following three
blocks of IP addresses specifically for private networks.
Table 10 Private IP Address Ranges
10.0.0.0 - 10.255.255.255
172.16.0.0 - 172.31.255.255
192.168.0.0 - 192.168.255.255
You can obtain your IP address from the IANA, from an ISP or have it assigned by
a private network. If you belong to a small organization and your Internet access
is through an ISP, the ISP can provide you with the Internet addresses for your
local networks. On the other hand, if you are part of a much larger organization,
you should consult your network administrator for the appropriate IP addresses.
Note: Regardless of your particular situation, do not create an arbitrary IP address;
always follow the guidelines above. For more information on address
assignment, please refer to RFC 1597, Address Allocation for Private Internets
and RFC 1466, Guidelines for Management of IP Address Space.
3.4.6 IP Address and Subnet Mask
Similar to the way houses on a street share a common street name, so too do
computers on a LAN share one common network number.
Where you obtain your network number depends on your particular situation. If
the ISP or your network administrator assigns you a block of registered IP
addresses, follow their instructions in selecting the IP addresses and the subnet
mask.
32
If the ISP did not explicitly give you an IP network number, then most likely you
have a single user account and the ISP will assign you a dynamic IP address when
the connection is established. The Internet Assigned Number Authority (IANA)
reserved this block of addresses specifically for private use; please do not use any
other number unless you are told otherwise. Let's say you select 192.168.1.0 as
the network number; which covers 254 individual addresses, from 192.168.1.1 to
NBG-416N User’s Guide
Page 33
192.168.1.254 (zero and 255 are reserved). In other words, the first three
numbers specify the network number while the last number identifies an individual
computer on that network.
Once you have decided on the network number, pick an IP address that is easy to
remember, for instance, 192.168.1.1, for your NBG-416N, but make sure that no
other device on your network is using that IP address.
The subnet mask specifies the network number portion of an IP address. Your
NBG-416N will compute the subnet mask automatically based on the IP address
that you entered. You don't need to change the subnet mask computed by the
NBG-416N unless you are instructed to do otherwise.
3.4.7 DNS Server Address Assignment
Use DNS (Domain Name System) to map a domain name to its corresponding IP
address and vice versa, for instance, the IP address of www.zyxel.com is
204.217.0.2. The DNS server is extremely important because without it, you must
know the IP address of a computer before you can access it.
Chapter 3 Connection Wizard
The NBG-416N can get the DNS server addresses in the following ways.
1 The ISP tells you the DNS server addresses, usually in the form of an information
sheet, when you sign up. If your ISP gives you DNS server addresses, enter them
in the DNS Server fields in the Wizard and/or WAN > Internet Connection
screen.
2 If the ISP did not give you DNS server information, leave the DNS Server fields
set to 0.0.0.0 in the Wizard screen and/or set to From ISP in the WAN >
Internet Connection screen for the ISP to dynamically assign the DNS server IP
addresses.

DNS (Domain Name System) is for mapping a domain name to its corresponding IP
address and vice versa. The DNS server is extremely important because without it, you
must know the IP address of a computer before you can access it. The NBG-416N uses a
system DNS server (in the order you specify here) to resolve domain names for DDNS and
the time server.

3.4.9 WAN MAC Address
Every Ethernet device has a unique MAC (Media Access Control) address. The MAC
address is assigned at the factory and consists of six pairs of hexadecimal
characters, for example, 00:A0:C5:00:00:02.
Table 12 Example of Network Properties for LAN Servers with Fixed IP Addresses

This chapter provides tutorials for your NBG-416N as follows:
• How to Connect to the Internet from an AP
• Configure Wireless Security Using WPS on both your NBG-416N and Wireless
Client
• Enable and Configure Wireless Security without WPS on your NBG-416N
5.2 How to Connect to the Internet from an AP
This section gives you an example of how to set up an access point (AP) and
wireless client (a notebook, B in this example) for wireless communication. B can
access the Internet through the AP wirelessly.
Figure 39 Wireless AP Connection to the Internet
5.2.1 Configure Wireless Security Using WPS on both your NBG-416N and Wireless Client
This section gives you an example of how to set up wireless network using WPS.
This example uses the NBG-416N 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).
NBG-416N User’s Guide

Chapter 5 Tutorials
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 5.2.1.1 on page 62.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 NBG-416N’s
interface. See Section 5.2.1.2 on page 63. This is the more secure method,
since one device can authenticate the other.
5.2.1.1 Push Button Configuration (PBC)
1 Make sure that your NBG-416N is turned on and that it is within range of your
computer.
2 Make sure that you have installed the wireless client (this example uses the
NWD210N) driver and utility in your notebook.
3 In the wireless client utility, find the WPS settings. Enable WPS and press the WPS
button (Start or WPS button)
4 Log into NBG-416N’s Web Configurator and press Push Button in the Network >
Wireless Client > WPS Station screen.
Note: Your NBG-416N has a WPS button located on its 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 NBG-416N 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 NBG-416N securely.

5.2.1.2 PIN Configuration
When you use the PIN configuration method, you need to use both NBG-416N’s
configuration interface and the client’s utilities.
1 Launch your wireless client’s configuration utility. Go to the WPS settings and
select the PIN method to get a PIN number.
2 Enter the PIN number to the PIN field in the Network > Wireless LAN > WPS
Station screen on the NBG-416N.
3 Click the Start buttons (or button next to the PIN field) on both the wireless client
utility screen and the NBG-416N’s WPS Station screen within two minutes.
The NBG-416N authenticates the wireless client and 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 NBG-416N securely.

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.
1 The NBG-416N 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.
2 Wireless 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.
3 After you’ve installed the utility, open it. If you cannot see your utility’s icon on

6.3 What You Should Know
Every wireless network must follow these basic guidelines.
• Every wireless client in the same wireless network must use the same SSID.
The SSID is the name of the wireless network. It stands for Service Set IDentity.
• If two wireless networks overlap, they should use different channels.
Like radio stations or television channels, each wireless network uses a specific
channel, or frequency, to send and receive information.
• Every wireless client in the same wireless network must use security compatible
with the AP.
Security stops unauthorized devices from using the wireless network. It can also
protect the information that is sent in the wireless network.
6.3.1 Wireless Security Overview
The following sections introduce different types of wireless security you can set up
in the wireless network.
Chapter 6 Wireless LAN
6.3.1.1 SSID
Normally, the AP acts like a beacon and regularly broadcasts the SSID in the area.
You can hide the SSID instead, in which case the AP does not broadcast the SSID.
In addition, you should change the default SSID to something that is difficult to
guess.
This type of security is fairly weak, however, because there are ways for
unauthorized devices to get the SSID. In addition, unauthorized devices can still
see the information that is sent in the wireless network.
6.3.1.2 MAC Address Filter
Every wireless client has a unique identification number, called a MAC address.1 A
MAC address is usually written using twelve hexadecimal characters
example, 00A0C5000002 or 00:A0:C5:00:00:02. To get the MAC address for each
wireless client, see the appropriate User’s Guide or other documentation.
You can use the MAC address filter to tell the AP which wireless clients are allowed
or not allowed to use the wireless network. If a wireless client is allowed to use the
wireless network, it still has to have the correct settings (SSID, channel, and
2
; for
1. Some wireless devices, such as scanners, can detect wireless networks but cannot use wireless networks.
These kinds of wireless devices might not have MAC addresses.
2. Hexadecimal characters are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F.
NBG-416N User’s Guide

Chapter 6 Wireless LAN
security). If a wireless client is not allowed to use the wireless network, it does not
matter if it has the correct settings.
This type of security does not protect the information that is sent in the wireless
network. Furthermore, there are ways for unauthorized devices to get the MAC
address of an authorized wireless client. Then, they can use that MAC address to
use the wireless network.
6.3.1.3 Encryption
Wireless networks can use encryption to protect the information that is sent in the
wireless network. Encryption is like a secret code. If you do not know the secret
code, you cannot understand the message.
The types of encryption you can choose depend on the type of user
authentication. (See Section 6.3.1.3 on page 74 for information.)
Table 26 Types of Encryption for Each Type of Authentication
Weakest No Security
Strongest WPA2-PSK
NO AUTHENTICATION
Static WEP
WPA-PSK
For example, if users do not log in to the wireless network, you can choose no
encryption, Static WEP, WPA-PSK, or WPA2-PSK.
Usually, you should set up the strongest encryption that every wireless client in
the wireless network supports. Suppose the wireless network has two wireless
clients. Device A only supports WEP, and device B supports WEP and WPA.
Therefore, you should set up Static WEP in the wireless network.
Note: It is recommended that wireless networks use WPA-PSK or stronger
encryption. IEEE 802.1x and WEP encryption are better than none at all, but it
is still possible for unauthorized devices to figure out the original information
pretty quickly.
When you select WPA2-PSK in your NBG-416N, you can also select an option
(WPA Compatible) to support WPA-PSK as well. In this case, if some wireless
clients support WPA-PSK and some support WPA2-PSK, you should set up WPA2-
PSK and select the WPA Compatible option in the NBG-416N.
Many types of encryption use a key to protect the information in the wireless
network. The longer the key, the stronger the encryption. Every wireless client in
the wireless network must have the same key.
74
NBG-416N User’s Guide

6.3.1.4 WPS
WiFi Protected Setup (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. Depending on the
devices in your network, you can either press a button (on the device itself, or in
its configuration utility) or enter a PIN (Personal Identification Number) in the
devices. Then, they connect and set up a secure network by themselves. See how
to set up a secure wireless network using WPS in the Section 5.2.1 on page 61.
6.4 General Wireless LAN Screen
Use this screen to enable the Wireless LAN, enter the SSID and select the wireless
security mode.
Note: If you are configuring the NBG-416N from a computer connected to the wirele ss
LAN and you change the NBG-416N’s SSID, channel or security settings, you
will lose your wireless connection when you press Apply to confirm. You must
then change the wireless settings of your computer to match the NBG-416N’s
new settings.

Control) address. The MAC address is assigned at the factory and consists of six
pairs of hexadecimal characters, for example, 00:A0:C5:00:00:02. You need to
know the MAC address of the devices to configure this screen.
Chapter 6 Wireless LAN
The Group Key Update Timer is the rate at which the AP (if using
WPA-PSK/WPA2-PSK key management) or RADIUS server (if using
WPA/WPA2 key management) sends a new group key out to all
clients. The re-keying process is the WPA/WPA2 equivalent of
automatically changing the WEP key for an AP and all stations in a
WLAN on a periodic basis. Setting of the Group Key Update Timer is
also supported in WPA-PSK/WPA2-PSK mode.

7.2.1 Configuring Your Internet Connection
Encapsulation Method
Encapsulation is used to include data from an upper layer protocol into a lower
layer protocol. To set up a WAN connection to the Internet, you need to use the
same encapsulation method used by your ISP (Internet Service Provider). If your
ISP offers a dial-up Internet connection using PPPoE (PPP over Ethernet) or PPTP
(Point-to-Point Tunneling Protocol), they should also provide a username and
password (and service name) for user authentication.
WAN IP Address
The WAN IP address is an IP address for the NBG-416N, which makes it accessible
from an outside network. It is used by the NBG-416N to communicate with other
devices in other networks. It can be static (fixed) or dynamically assigned by the
ISP each time the NBG-416N tries to access the Internet.
If your ISP assigns you a static WAN IP address, they should also assign you the
subnet mask and DNS server IP address(es) (and a gateway IP address if you use
the Ethernet or ENET ENCAP encapsulation method).
DNS Server Address Assignment
Use Domain Name System (DNS) to map a domain name to its corresponding IP
address and vice versa, for instance, the IP address of www.zyxel.com is
204.217.0.2. The DNS server is extremely important because without it, you must
know the IP address of a computer before you can access it.
The NBG-416N can get the DNS server addresses in the following ways.
1 The ISP tells you the DNS server addresses, usually in the form of an information
sheet, when you sign up. If your ISP gives you DNS server addresses, manually
enter them in the DNS server fields.
2 If your ISP dynamically assigns the DNS server IP addresses (along with the NBG-
416N’s WAN IP address), set the DNS server fields to get the DNS server address
from the ISP.

WAN MAC Address
The MAC address screen allows users to configure the WAN port's MAC address by
either using the factory default or cloning the MAC address from a computer on
your LAN. Choose Factory Default to select the factory assigned default MAC
Address.
NBG-416N User’s Guide
Page 93
Otherwise, click Clone the computer's MAC address - IP Address and enter
the IP address of the computer on the LAN whose MAC you are cloning. Once it is
successfully configured, the address will be copied to configuration file. It is
recommended that you clone the MAC address prior to hooking up the WAN Port.

7.3.2 PPPoE Encapsulation
The NBG-416N supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is
an IETF standard (RFC 2516) specifying how a personal computer (PC) interacts
with a broadband modem (DSL, cable, wireless, etc.) connection. The PPP over
Ethernet option is for a dial-up connection using PPPoE.
For the service provider, PPPoE offers an access and authentication method that
works with existing access control systems (for example Radius).
One of the benefits of PPPoE is the ability to let you 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 individuals.
Operationally, PPPoE saves significant effort for both you and the ISP or carrier, as
it requires no specific configuration of the broadband modem at the customer site.
By implementing PPPoE directly on the NBG-416N (rather than individual
computers), the computers on the LAN do not need PPPoE software installed,
since the NBG-416N does that part of the task. Furthermore, with NAT, all of the
LANs’ computers will have access.
