Getting Started
This chapter introduces the NWD210N and prepares you to use the ZyXEL utility. The
ZyXEL utility is a tool that helps you configure your NWD210N.
1.1 About Your NWD210N
Your NWD210N is an IEEE 802.11n draft 2.0 compliant wireless LAN adapter. It can also
connect to IEEE 802.11b/g wireless networks. The NWD210N is WPS (Wi-Fi Protected
Setup) compliant. WPS allows you to easily connect to another WPS-enabled device.
The NWD210N is a USB adapter which connects to an empty USB port on your computer.
See your NWD210N’s Quick Start Guide for installation instructions, and see the chapter on
product specifications for detailed information.
1.1.1 Hardware
This section describes the NWD210N’s physical appearance.

1.2 Application Overview
This section describes some network applications for the NWD210N. You can either set the
network type to Infrastructure and connect to an AP or use Ad-Hoc mode and connect to a
peer computer (another wireless device in Ad-Hoc mode).
1.2.1 Infrastructure
To connect to a network via an access point (AP), set the NWD210N network type to
Infrastructure (see Chapter 4 on page 56). Through the AP, you can access the Internet or the
wired network behind the AP.

Figure 2 Application: Infrastructure
1.2.2 Ad-Hoc
To set up a small independent wireless workgroup without an AP, use Ad-Hoc (see Chapter 4
on page 56).
Ad-Hoc does not require an AP or a wired network. Two or more wireless clients
communicate directly with each other.
Wi-Fi Protected Setup (WPS) is not available in ad-hoc mode.

2.1 Connecting to an AP using Wi-Fi Protected Setup (WPS)
This section gives you an example of how to set up your wireless network using WPS. This
example uses the NWD210N as the wireless client, and ZyXEL’s NBG334W as the Access
Point (AP).
The Access Point must be a WPS-aware device.
There are two WPS methods for creating a secure connection. This tutorial shows you both.
• Push Button Configuration (PBC) - create a secure wireless network simply by pressing
a button. See Section 2.1.1 on page 27.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 NWD210N’s interface. See Section
2.1.2 on page 29. This is the more secure method, since one device can authenticate the
other.
2.1.1 Push Button Configuration (PBC)
1 Make sure that your access point is turned on and that it is within range of the computer
with the NWD210N installed.
2 Make sure that you have installed the NWD210N’s driver and utility on your computer.

4 Log into the AP’s web configurator and locate its WPS settings section. On the
NBG334W, press the Push Button button in the Network > Wireless Client > WPS
Station screen.
It doesn’t matter which button is pressed first. You must press the second
button within two minutes of pressing the first one.
The AP sends the proper configuration settings to the NWD210N. This may take up to two
minutes. Then the NWD210N is able to communicate with the AP securely.
The following figure shows you an example to set up wireless network and security by
pressing a button on both the AP (the NBG334W in this example) and the NWD210N.

2.2 Connecting to an AP Without Using WPS
There are three ways to connect the wireless client (the NWD210N) to a network without
using WPS.
• Configure nothing and leave the wireless client to automatically scan for and connect to
any available network that has no wireless security configured.
• Manually connect to a network (see Section 2.2.1 on page 32).
• Configure a profile to have the wireless client automatically connect to a specific network
or peer computer (see Section 2.2.2 on page 34).
2.2.1 Manually Connecting to a Wireless LAN
This example illustrates how to manually connect your wireless client to an access point (AP)
configured for WPA-PSK security and connected to the Internet. Before you connect to the
access point, you must know its Service Set IDentity (SSID) and WPA-PSK pre-shared key. In
this example, the AP’s SSID is “SSID_Example3” and its pre-shared key is “ThisismyWPAPSKpre-sharedkey”.
After you install the ZyXEL utility and then insert the wireless client, follow the steps below
to connect to a network using the Site Survey screen.
1 Open the ZyXEL utility and click the Site Survey tab to open the screen shown next.
Figure 9 ZyXEL Utility: Site Survey
2 The wireless client automatically searches for available wireless networks. Click Scan if
you want to search again. If no entry displays in the Available Network List, that means
there is no wireless network available within range. Make sure the AP or peer computer
is turned on, or move the wireless client closer to the AP or peer computer. See Table 4.3
on page 49 for detailed field descriptions.
3 To connect to an AP or peer computer, either click an entry in the list and then click
Connect or double-click an entry (SSID_Example3 in this example).
4 When you try to connect to an AP with security configured, a window will pop up
prompting you to specify the security settings. Enter the pre-shared key and leave the
encryption type at the default setting.
Use the Next button to move on to the next screen. You can use the Back button at any
time to return to the previous screen, or the Exit button to return to the Site Survey
screen.

2.2.2 Creating and Using a Profile
A profile lets you automatically connect to the same wireless network every time you use the
ZyXEL utility. You can also configure different profiles for different networks, for example if
you connect a notebook computer to wireless networks at home and at work.
This example illustrates how to set up a profile and connect the wireless client to an access
point configured for WPA-PSK security. In this example, the AP’s SSID is “SSID_Example3”
and its pre-shared key is “ThisismyWPA-PSKpre-sharedkey”. You have chosen the profile
name “PN_Example3”.
1 Open the ZyXEL utility and click the Profile tab to open the screen as shown. Click Add
to configure a new profile.
Figure 13 ZyXEL Utility: Profile
2 The Add New Profile screen appears. The wireless client automatically searches for
available wireless networks, which are displayed in the Scan Info box. You can also
configure your profile for a wireless network that is not in the list.

Wireless LANs
This chapter provides background information on wireless Local Area Networks.
3.1 Wireless LAN Overview
The following figure provides an example of a wireless network with an AP. See Figure 3 on
page 23 for an Ad Hoc network example.
Figure 19 Example of a Wireless Network
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
Every wireless network must follow these basic guidelines.
• Every device 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 a different channel.
NWD210N User’s Guide
37
Chapter 3 Wireless LANs
Like radio stations or television channels, each wireless network uses a specific channel,
or frequency, to send and receive information.
• Every device in the same wireless network must use security compatible with the AP or
peer computer.
Security stops unauthorized devices from using the wireless network. It can also protect
the information that is sent in the wireless network.
3.2 Wireless LAN Security
Wireless LAN security is vital to your network to protect wireless communications.
If you do not enable any wireless security on your NWD210N, the NWD210N’s wireless
communications are accessible to any wireless networking device that is in the coverage area.
You can use only WEP encryption if you set the NWD210N to Ad-hoc mode.
See the appendices for more detailed information about wireless security.
3.2.1 User Authentication and Encryption
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.
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.
3.2.1.1 WEP
3.2.1.1.1 Data Encryption
WEP (Wired Equivalent Privacy) encryption scrambles all data packets transmitted between
the NWD210N and the AP or other wireless stations to keep network communications private.
Both the wireless stations and the access points must use the same WEP key for data
encryption and decryption.
There are two ways to create WEP keys in your NWD210N.
• Automatic WEP key generation based on a “password phrase” called a passphrase. The
passphrase is case sensitive. You must use the same passphrase for all WLAN adapters
with this feature in the same WLAN.
For WLAN adapters without the passphrase feature, you can still take advantage of this
feature by writing down the four automatically generated WEP keys from the Security
Settings screen of the ZyXEL utility and entering them manually as the WEP keys in the
other WLAN adapter(s).
• Enter the WEP keys manually.
38
NWD210N User’s Guide
Chapter 3 Wireless LANs
Your NWD210N allows you to configure up to four 64-bit, 128-bit or 152-bit WEP keys.
Only one key is used as the default key at any one time.
3.2.1.1.2 Authentication Type
The IEEE 802.11b/g standard describes a simple authentication method between the wireless
stations and AP. Three authentication types are defined: Auto, Open and Shared.
• Open mode is implemented for ease-of-use and when security is not an issue. The
wireless station and the AP or peer computer do not share a secret key. Thus the wireless
stations can associate with any AP or peer computer and listen to any transmitted data that
is not encrypted.
• Shared mode involves a shared secret key to authenticate the wireless station to the AP or
peer computer. This requires you to enable the wireless LAN security and use same
settings on both the wireless station and the AP or peer computer.
• Auto authentication mode allows the NWD210N to switch between the open system and
shared key modes automatically. Use the auto mode if you do not know the authentication
mode of the other wireless stations.
3.2.1.2 IEEE 802.1x
The IEEE 802.1x standard outlines enhanced security methods for both the authentication of
wireless stations and encryption key management. Authentication can be done using an
external RADIUS server.
3.2.1.2.1 EAP Authentication
EAP (Extensible Authentication Protocol) is an authentication protocol that runs on top of the
IEEE 802.1x transport mechanism in order to support multiple types of user authentication. By
using EAP to interact with an EAP-compatible RADIUS server, an access point helps a
wireless station and a RADIUS server perform authentication.
The type of authentication you use depends on the RADIUS server and an intermediary AP(s)
that supports IEEE 802.1x. The NWD210N supports EAP-TLS, EAP-TTLS (at the time of
writing, TTLS is not available in Windows Vista) and EAP-PEAP. Refer to Appendix B on
page 103 for descriptions.
For EAP-TLS authentication type, you must first have a wired connection to the network and
obtain the certificate(s) from a certificate authority (CA). Certificates (also called digital IDs)
can be used to authenticate users and a CA issues certificates and guarantees the identity of
each certificate owner.
3.2.1.3 WPA and WPA2
Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. WPA2 (IEEE
802.11i) is a wireless security standard that defines stronger encryption, authentication and
key management than WPA.
Key differences between WPA(2) and WEP are improved data encryption and user
authentication.
Both WPA and WPA2 improve data encryption by using Temporal Key Integrity Protocol
(TKIP), Message Integrity Check (MIC) and IEEE 802.1x. WPA and WPA2 use Advanced
Encryption Standard (AES) in the Counter mode with Cipher block chaining Message
authentication code Protocol (CCMP) to offer stronger encryption than TKIP.
NWD210N User’s Guide
39
Chapter 3 Wireless LANs
If both an AP and the wireless clients support WPA2 and you have an external RADIUS
server, use WPA2 for stronger data encryption. If you don't have an external RADIUS server,
you should use WPA2-PSK (WPA2-Pre-Shared Key) that only requires a single (identical)
password entered into each access point, wireless gateway and wireless client. As long as the
passwords match, a wireless client will be granted access to a WLAN.
If the AP or the wireless clients do not support WPA2, just use WPA or WPA-PSK depending
on whether you have an external RADIUS server or not.
Select WEP only when the AP and/or wireless clients do not support WPA or WPA2. WEP is
less secure than WPA or WPA2.
3.3 WiFi Protected Setup
Your NWD210N 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.
3.3.1 Push Button Configuration
WPS Push Button Configuration (PBC) is initiated by pressing a button on each WPS-enabled
device, and allowing them to connect automatically. You do not need to enter any information.
Not every WPS-enabled device has a physical WPS button. Some may have a WPS PBC
button in their configuration utilities instead of or in addition to the physical button.
Take the following steps to set up WPS using the button.
1 Ensure that the two devices you want to set up are within wireless range of one another.
2 Look for a WPS button on each device. If the device does not have one, log into its
configuration utility and locate the button (see the device’s User’s Guide for how to do
this - for the NWD210N, see Section 4.5.1 on page 62).
3 Press the button on one of the devices (it doesn’t matter which).
4 Within two minutes, press the button on the other device. The registrar sends the network
name (SSID) and security key through an secure connection to the enrollee.
If you need to make sure that WPS worked, check the list of associated wireless clients in the
AP’s configuration utility. If you see the wireless client in the list, WPS was successful.
40
NWD210N User’s Guide
Chapter 3 Wireless LANs
3.3.2 PIN Configuration
Each WPS-enabled device has its own PIN (Personal Identification Number). This may either
be static (it cannot be changed) or dynamic (in some devices you can generate a new PIN by
clicking on a button in the configuration interface).
Use the PIN method instead of the push-button configuration (PBC) method if you want to
ensure that the connection is established between the devices you specify, not just the first two
devices to activate WPS in range of each other. However, you need to log into the
configuration interfaces of both devices to use the PIN method.
When you use the PIN method, you must enter the PIN from one device (usually the wireless
client) into the second device (usually the Access Point or wireless router). Then, when WPS
is activated on the first device, it presents its PIN to the second device. If the PIN matches, one
device sends the network and security information to the other, allowing it to join the network.
Take the following steps to set up a WPS connection between an access point or wireless
router (referred to here as the AP) and a client device using the PIN method.
1 Ensure WPS is enabled on both devices.
2 Access the WPS section of the AP’s configuration interface. See the device’s User’s
Guide for how to do this.
3 Look for the client’s WPS PIN; it will be displayed either on the device, or in the WPS
section of the client’s configuration interface (see the device’s User’s Guide for how to
find the WPS PIN - for the NWD210N, see Section 4.5 on page 61).
4 Enter the client’s PIN in the AP’s configuration interface.
If the client device’s configuration interface has an area for entering another
device’s PIN, you can either enter the client’s PIN in the AP, or enter the AP’s
PIN in the client - it does not matter which.
5 Start WPS on both devices within two minutes.
Use the configuration utility to activate WPS, not the push-button on the device
itself.
6 On a computer connected to the wireless client, try to connect to the Internet. If you can
connect, WPS was successful.
If you cannot connect, check the list of associated wireless clients in the AP’s
configuration utility. If you see the wireless client in the list, WPS was successful.
The following figure shows a WPS-enabled wireless client (installed in a notebook computer)
connecting to the WPS-enabled AP via the PIN method.

3.3.3 How WPS Works
When two WPS-enabled devices connect, each device must assume a specific role. One device
acts as the registrar (the device that supplies network and security settings) and the other
device acts as the enrollee (the device that receives network and security settings. The registrar
creates a secure EAP (Extensible Authentication Protocol) tunnel and sends the network name
(SSID) and the WPA-PSK or WPA2-PSK pre-shared key to the enrollee. Whether WPA-PSK
or WPA2-PSK is used depends on the standards supported by the devices. If the registrar is
already part of a network, it sends the existing information. If not, it generates the SSID and
WPA(2)-PSK randomly.
The following figure shows a WPS-enabled client (installed in a notebook computer)
connecting to a WPS-enabled access point.

REGISTRAR
SECURITY INFO
COMMUNICATION
The roles of registrar and enrollee last only as long as the WPS setup process is active (two
minutes). The next time you use WPS, a different device can be the registrar if necessary.
The WPS connection process is like a handshake; only two devices participate in each WPS
transaction. If you want to add more devices you should repeat the process with one of the
existing networked devices and the new device.
Note that the access point (AP) is not always the registrar, and the wireless client is not always
the enrollee. All WPS-certified APs can be a registrar, and so can some WPS-enabled wireless
clients.
By default, a WPS devices is “unconfigured”. This means that it is not part of an existing
network and can act as either enrollee or registrar (if it supports both functions). If the registrar
is unconfigured, the security settings it transmits to the enrollee are randomly-generated. Once
a WPS-enabled device has connected to another device using WPS, it becomes “configured”.
A configured wireless client can still act as enrollee or registrar in subsequent WPS
connections, but a configured access point can no longer act as enrollee. It will be the registrar
in all subsequent WPS connections in which it is involved. If you want a configured AP to act
as an enrollee, you must reset it to its factory defaults.
3.3.3.1 Example WPS Network Setup
This section shows how security settings are distributed in an example WPS setup.
The following figure shows an example network. In step 1, both AP1 and Client 1 are
unconfigured. When WPS is activated on both, they perform the handshake. In this example,
AP1 is the registrar, and Client 1 is the enrollee. The registrar randomly generates the security
information to set up the network, since it is unconfigured and has no existing information.

In step 2, you add another wireless client to the network. You know that Client 1 supports
registrar mode, but it is better to use AP1 for the WPS handshake with the new client since
you must connect to the access point anyway in order to use the network. In this case, AP1
must be the registrar, since it is configured (it already has security information for the
network). AP1 supplies the existing security information to Client 2.

In step 3, you add another access point (AP2) to your network. AP2 is out of range of AP1, so
you cannot use AP1 for the WPS handshake with the new access point. However, you know
that Client 2 supports the registrar function, so you use it to perform the WPS handshake
instead.

3.3.4 Limitations of WPS
WPS has some limitations of which you should be aware.
• WPS works in Infrastructure networks only (where an AP and a wireless client
communicate). It does not work in Ad-Hoc networks (where there is no AP).
• When you use WPS, it works between two devices only. You cannot enroll multiple
devices simultaneously, you must enroll one after the other.
For instance, if you have two enrollees and one registrar you must set up the first enrollee
(by pressing the WPS button on the registrar and the first enrollee, for example), then
check that it successfully enrolled, then set up the second device in the same way.
• WPS works only with other WPS-enabled devices. However, you can still add non-WPS
devices to a network you already set up using WPS.
WPS works by automatically issuing a randomly-generated WPA-PSK or WPA2-PSK
pre-shared key from the registrar device to the enrollee devices (see Section 4.3.1.2 on
page 52 for information on pre-shared keys). Whether the network uses WPA-PSK or
WPA2-PSK depends on the device. You can check the configuration interface of the
registrar device to discover the key the network is using (if the device supports this
feature). Then, you can enter the key into the non-WPS device and join the network as
normal (the non-WPS device must also support WPA-PSK or WPA2-PSK).
• When you use the PBC method, there is a short period (from the moment you press the
button on one device to the moment you press the button on the other device) when any
WPS-enabled device could join the network. This is because the registrar has no way of
identifying the “correct” enrollee, and cannot differentiate between your enrollee and a
rogue device. This is a possible way for a hacker to gain access to a network.
NWD210N User’s Guide
45
Chapter 3 Wireless LANs
You can easily check to see if this has happened. WPS works between only two devices
simultaneously, so if another device has enrolled your device will be unable to enroll, and
will not have access to the network. If this happens, open the access point’s configuration
interface and look at the list of associated clients (usually displayed by MAC address). It
does not matter if the access point is the WPS registrar, the enrollee, or was not involved
in the WPS handshake; a rogue device must still associate with the access point to gain
access to the network. Check the MAC addresses of your wireless clients (usually printed
on a label on the bottom of the device). If there is an unknown MAC address you can
remove it or reset the AP.

A profile is a set of wireless parameters that you need to connect to a wireless network. With a
profile activated, each time you start the NWD210N, it automatically scans for the specific
SSID and joins that network with the pre-defined wireless security settings. If the specified
network is not available, the NWD210N cannot connect to a network.
If you do not configure and activate a profile, each time you start the NWD210N, the
NWD210N uses the default profile to connect to any available network that has no security
enabled.
The default profile is a profile that allows you to connect to any SSID that has no security
enabled.
