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
12
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
1 Make sure the power LED is on.
2 Press the RESET button for one to four seconds to restart/reboot the NBG6616.
3 Press 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.

CHAPTER 8
8.1 Overview
This chapter provides tutorials for setting up your NBG6616.
• Set Up a Wireless Network Using WPS
• Connect to Wireless Networks without WPS
• Using Multiple SSIDs on the NBG6616
8.2 Set Up a Wireless Network Using WPS
This section gives you an example of how to set up wireless network using WPS. This example uses
the NBG6616 as the AP and NWD210N as the wireless client which connects to a notebook.
Tutorials
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 via the web configurator or utility.
This tutorial shows you how to do both.
• Push Button Configuration (PBC) - create a secure wireless network simply by pressing a
button. See Section 8.2.1 on page 56. 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 NBG6616’s interface. See Section 8.2.2 on page 57. This
is the more secure method, since one device can authenticate the other.
8.2.1 Push Button Configuration (PBC)
1 Make sure that your NBG6616 is turned on. Make sure the WIFI button (at the back panel of the
NBG6616) is pushed in, and that the device is placed within range of your notebook.
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 NBG6616’s Web Configurator and press the Push Button in the Configuration >
Network > Wireless LAN 2.4G > WPS Station screen.

Note: Your NBG6616 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 NBG6616 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 NBG6616 securely.
The following figure shows you an example to set up wireless network and security by pressing a
button on both NBG6616 and wireless client (the NWD210N in this example).
Figure 38 Example WPS Process: PBC Method
8.2.2 PIN Configuration
When you use the PIN configuration method, you need to use both NBG6616’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.

sure you entered the correct security key.
If the connection has limited or no connectivity, make sure the DHCP server is enabled on the
NBG6616.
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.
8.4 Using Multiple SSIDs on the NBG6616
You can configure more than one SSID on a NBG6616. See Section 11.4 on page 97.
This allows you to configure multiple independent wireless networks on the NBG6616 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 NBG6616 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 NBG6616 (such as
a printer).

10.1 Overview
This chapter discusses the NBG6616’s WAN screens. Use these screens to configure your NBG6616
for Internet access.
A WAN (Wide Area Network) connection is an outside connection to another network or the
Internet. It connects your private networks such as a LAN (Local Area Network) and other
networks, so that a computer in one location can communicate with computers in other locations.

10.2 What You Can Do
•Use the Internet Connection screen to enter your ISP information and set how the computer
acquires its IP, DNS and WAN MAC addresses (Section 10.4 on page 76).
•Use the Advanced screen to enable multicasting, configure Windows networking and bridge
(Section 10.5 on page 82).
10.3 What You Need To Know

Chapter 10 WAN
10.3.1 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 NBG6616, which makes it accessible from an outside
network. It is used by the NBG6616 to communicate with other devices in other networks. It can be
static (fixed) or dynamically assigned by the ISP each time the NBG6616 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 NBG6616 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 NBG6616’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.
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.
NBG6616 User’s Guide
75
Chapter 10 WAN
Multicast
Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender - 1 recipient)
or Broadcast (1 sender - everybody on the network). Multicast delivers IP packets to a group of
hosts on the network - not everybody and not just 1.
Figure 46 Multicast Example
In the multicast example above, systems A and D comprise one multicast group. In multicasting,
the server only needs to send one data stream and this is delivered to systems A and D.
IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to establish membership
in a multicast group - it is not used to carry user data. The NBG6616 supports both IGMP version 1
(IGMP-v1) and IGMP version 2 (IGMP-v2).
At start up, the NBG6616 queries all directly connected networks to gather group membership.
After that, the NBG6616 periodically updates this information. IP multicasting can be enabled/
disabled on the NBG6616 WAN interface in the Web Configurator (WAN). Select None to disable IP
multicasting on these interfaces.

10.4.2 PPPoE Encapsulation
The NBG6616 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 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 LANs’ computers will have access.

This chapter discusses how to configure the wireless network settings in your NBG6616. The
NBG6616 is able to function both 2.4GHz and 5GHz network at the same time. You can have
different wireless and wireless security settings for 2.4GHz and 5GHz wireless LANs. Click
Configuration > Network > Wireless LAN 2.4G or Wireless LAN 5G to configure to do so.
See the appendices for more detailed information about wireless networks.
The following figure provides an example of a wireless network.
Figure 50 Example of a Wireless Network
CHAPTER 11
Wireless LAN
The wireless network is the part in the blue circle. In this wireless network, devices A and B are
called wireless clients. The wireless clients use the access point (AP) to interact with other devices
(such as the printer) or with the Internet. Your NBG6616 is the AP.
NBG6616 User’s Guide
84
11.1.1 What You Can Do
•Use the General screen to turn the wireless connection on or off, set up wireless security
between the NBG6616 and the wireless clients, and make other basic configuration changes
(Section 11.2 on page 89).
•Use the More AP screen to set up multiple wireless networks on your NBG6616 (Section 11.4 on
page 97).
•Use the MAC Filter screen to allow or deny wireless stations based on their MAC addresses from
connecting to the NBG6616 (Section 11.5 on page 100).
•Use the Advanced screen to allow intra-BSS networking and set the RTS/CTS Threshold (Section
11.6 on page 102).
•Use the QoS screen to ensure Quality of Service (QoS) in your wireless network (Section 11.7 on
page 102).
•Use the WPS screen to quickly set up a wireless network with strong security, without having to
configure security settings manually (Section 11.8 on page 103).
•Use the WPS Station screen to add a wireless station using WPS (Section 11.9 on page 105).
•Use the Scheduling screen to set the times your wireless LAN is turned on and off (Section
11.10 on page 105).
Chapter 11 Wireless LAN
11.1.2 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.
Wireless Security Overview
The following sections introduce different types of wireless security you can set up in the wireless
network.
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.
NBG6616 User’s Guide
85
MAC Address Filter
Chapter 11 Wireless LAN
Every wireless client has a unique identification number, called a MAC address.1 A MAC address is
usually written using twelve hexadecimal characters
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 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.

User Authentication
You can make every user log in to the wireless network before they can use it. This is called user
authentication. However, every wireless client in the wireless network has to support IEEE 802.1x
to do this.
For wireless networks, there are two typical places to store the user names and passwords for each
user.
• In the AP: this feature is called a local user database or a local database.
• In a RADIUS server: this is a server used in businesses more than in homes.
If your AP does not provide a local user database and if you do not have a RADIUS server, you
cannot set up user names and passwords for your users.
Unauthorized devices can still see the information that is sent in the wireless network, even if they
cannot use the wireless network. Furthermore, there are ways for unauthorized wireless users to
get a valid user name and password. Then, they can use that user name and password to use the
wireless network.
Local user databases also have an additional limitation that is explained in the next section.
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.
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.
NBG6616 User’s Guide

Chapter 11 Wireless LAN
The types of encryption you can choose depend on the type of user authentication. (See page 86
for information about this.)
Table 29 Types of Encryption for Each Type of Authentication
NO AUTHENTICATION RADIUS SERVER
Weakest No Security WPA
Static WEP
WPA-PSK
Strongest WPA2-PSK WPA2
For example, if the wireless network has a RADIUS server, you can choose WPA or WPA2. 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. For example, suppose the AP does not have a local user database, and you do
not have a RADIUS server. Therefore, there is no user authentication. 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, WPA, 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.
Note: It is not possible to use WPA-PSK, WPA or stronger encryption with a local user
database. In this case, it is better to set up stronger encryption with no
authentication than to set up weaker encryption with the local user database.
When you select WPA2 or WPA2-PSK in your NBG6616, you can also select an option (WPA/
WPA-PSK Compatible) to support WPA/WPA-PSK as well. In this case, if some wireless clients
support WPA and some support WPA2, you should set up WPA2-PSK or WPA2 (depending on the
type of wireless network login) and select the WPA/WPA-PSK Compatible option in the
NBG6616.
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.
Guest WLAN
Guest WLAN allows you to set up a wireless network where users can access to Internet via the
NBG6616 (Z), but not other networks connected to the Z. In the following figure, a guest user can
access the Internet from the guest wireless network A via Z but not the home or company network
N.
Note: The home or company network N and Guest WLAN network are independent
networks.
Note: Only Router mode supports guest WLAN.

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
