Applications
The wireless LAN products are easy to install and highly efficient. The following list
describes some of the many applications made possible through the power and
flexibility of wireless LANs:
a) Difficult to wire environments
There are many situations where wires cannot be laid easily. Historic
buildings, older buildings, open areas and across busy streets make the
installation of wired LANs either impossible or very expensive.
b) Temporary workgroups
Consider situations in parks, athletic arenas, exhibition centers, disaster-
recovery, temporary offices and construction sites where one wants a
temporary WLAN established and removed.
c) The ability to access real-time information
Doctors/nurses, point-of-sale employees, and warehouse workers can
access real-time information while dealing with patients, serving
customers and processing information.
d) Frequently changed environments
Show rooms, meeting rooms, retail stores, and manufacturing sites where
frequently rearrange the workplace.
e) Small Office and Home Office (SOHO) networks
SOHO users need a cost-effective, easy and quick installation of a small
network.
f) Wireless extensions to Ethernet networks
6
Network managers in dynamic environments can minimize the overhead
caused by moves, extensions to networks, and other changes with
wireless LANs.
g) Wired LAN backup
Network managers implement wireless LANs to provide backup for
mission-critical applications running on wired networks.
h) Training or Educational facilities
Training sites at corporations and students at universities use wireless
connectivity to ease access to information, information exchanges, and
learning.
Network Configuration
To better understand how the wireless LAN products work together to create a
wireless network, it might be helpful to depict a few of the possible wireless LAN PC
card network configurations. The wireless LAN products can be configured as:
a) Ad-hoc (or peer-to-peer) for departmental or SOHO LANs.
b) Infrastructure for enterprise LANs.
a) Ad-hoc (peer-to-peer) Mode
This is the simplest network configuration with several computers
equipped with the Network Interface Cards that form a wireless network
whenever they are within range of one another. In ad-hoc mode, each
client is peer-to-peer, would only have access to the resources of the
other client and does not require an access point. This is the easiest and
least expensive way for the SOHO to set up a wireless network. The
image below depicts a network in an ad-hoc mode.
b) Infrastructure Mode
7
The infrastructure mode requires the use of an Access Point (AP) or a a
router. In this mode, all wireless communication between two computers
has to be via the AP. It doesn’t matter if the AP is stand-alone or wired to
an Ethernet network. If used in stand-alone, the AP can extend the range
of independent wireless LANs by acting as a repeater, which effectively
doubles the distance between wireless stations. The image below
depicts a network in infrastructure mode.
ENUWI-N3 for Windows® XP & Windows Vista®
Before You Begin
During the installation, the Windows XP setup process may need to copy some
systems files from its original Windows installation CD. It is highly advisable to have
your Windows XP original setup disc handy in case installation ask for system files.

Authentication and Security
The Security tab allows you to configure the authentication and encryption
settings such as: WEP, WPA, WPA-PSK, WPA2, and 802.1x. Each security
option is described in detail below.
WEP Encryption
The WEP tab displays the WEP settings. Encryption is designed to make the
data transmission more secure. You may select 64 or 128-bit WEP (Wired
Equivalent Privacy) key to encrypt data (Default setting is Disable). WEP
encrypts each frame transmitted from the radio using one of the Keys from a
panel. When you use WEP to communicate with the other wireless clients, all the
wireless devices in this network must have the same encryption key or pass
phrase. The following information is included in this tab, as the image depicts
below.
Authentication Type: Select Open or Shared from the drop-down list.
Encryption: Select WEP from the drop-down list.
17
WEP Key (Hex or ASCII): Type a character string into the field. For 64-bit
enter 5 alphanumeric or 10 hexadecimal characters. For 128-bit enter 13
alphanumeric or 26 hexadecimal characters.
Click on the Apply button to save the changes.
Show Password check box. If you want to make sure the accuracy of
password you type, click the Show Password box to check it.
WPA, WPA2 Authentication & TKIP, AES Encryption
WPA (Wi-Fi Protected Access) was designed to improve upon the security
features of WEP (Wired Equivalent Privacy). This is used along with 802.1x
security setting. The technology is designed to work with existing Wi-Fi products
that have been enabled with WEP. WPA provides improved data encryption
through the Temporal Integrity Protocol (TKIP), which scrambles the keys using a
hashing algorithm and by adding an integrity-checking feature which makes sure
that keys haven’t been tampered with. EAP (Extensible Authentication Protocol)
is an extension to the PPP protocol that enables a variety of authentication
protocols to be used. It passes through the exchange of authentication messages,
allowing the authentication software stored in a server to interact with its
counterpart in the client.
Authentication Type: Select WPA or WPA2 from the drop-down list.
Encryption: Select TKIP or AES from the drop-down list.
Click on the Apply button to save the changes.
Show Password check box. If you want to make sure the accuracy of
password you type, click the Show Password box to check it.
WPA-PSK Authentication & TKIP, AES Encryption
WPA – PSK (Pre-shared Key) is used in a Pre Shared Key mode that does not
require an authentication server. Access to the Internet and the rest of the
wireless network services is allowed only if the pre-shared key of the computer
matches that of the Access Point. This approach offers the simplicity of the WEP
18
key, but uses stronger TKIP encryption. EAP (Extensible Authentication Protocol)
is an extension to the PPP protocol that enables a variety of authentication
protocols to be used. It passes through the exchange of authentication messages,
allowing the authentication software stored in a server to interact with its
counterpart in the client.
Authentication Type: Select WPA-PSK or WPA2-PSK from the drop-down
list.
Encryption: Select TKIP or AES from the drop-down list.
WPA Preshared key: Enter a pass phrase which is between 8 and 32
characters long.
Click on the Apply button to save the changes.
Show Password check box. If you want to make sure the accuracy of
password you type, click the Show Password box to check it.
LEAP Authentication
LEAP (Lightweight Extensible Authentication Protocol) also known as Cisco-
Wireless EAP provides username/password-based authentication between a
wireless client and a RADIUS server. LEAP is one of several protocols used with
the IEEE 802.1X standard for LAN port access control. LEAP also delivers a
session key to the authenticated station, so that future frames can be encrypted
with a key that is different than keys used by others sessions. Dynamic key
delivery eliminates one big vulnerability; static encryption keys that are shared by
all stations in the WLAN. EAP (Extensible Authentication Protocol) is an
extension to the PPP protocol that enables a variety of authentication protocols
to be used. It passes through the exchange of authentication messages, allowing
the authentication software stored in a server to interact with its counterpart in the
client
19
Authentication Type: Select LEAP from the drop-down list.
Identity: Enter the user name.
Password: Enter the password.
Domain: Enter a domain name.
Encryption: Select WEP, WPA-TKIP or WPA2-AES encryption.
Click on the OK button to save the changes.
802.1x with PEAP
802.1X provides an authentication framework for wireless LANs allowing a user
to be authenticated by a central authority. 802.1X uses an existing protocol called
EAP. EAP (Extensible Authentication Protocol) is an extension to the PPP
protocol that enables a variety of authentication protocols to be used. It passes
through the exchange of authentication messages, allowing the authentication
software stored in a server to interact with its counterpart in the client.
PEAP Authentication with EAP/TLS Smartcard
EAP/TLS Smartcard provides for certificate-based and mutual authentication of
the client and the network. It relies on client-side and server-side certificates to
perform authentication and can be used to dynamically generate user-based and
session-based WEP keys to secure subsequent communications between the
WLAN client and the access point.
20
Authentication Type: Select PEAP from the drop-down list.
Protocol: If your network uses TLS or Smart Card to authenticate its users,
select TLS/Smartcard from the drop down list. TLS (Transport Layer
Security) is an IETF standardized authentication protocol that uses PKI
(Public Key Infrastructure) certificate-based authentication of both the client
and authentication server.
Identity: Enter the user name.
Click on the OK button to save the changes.
802.1x with TTLS with EAP-MD5, MS-CHAP, MS-CHAPv2
802.1X provides an authentication framework for wireless LANs allowing a user
to be authenticated by a central authority. 802.1X uses an existing protocol called
EAP. EAP (Extensible Authentication Protocol) is an extension to the PPP
protocol that enables a variety of authentication protocols to be used. It passes
through the exchange of authentication messages, allowing the authentication
software stored in a server to interact with its counterpart in the client. TLS
(Transport Layer Security) is an IETF standardized authentication protocol that
uses PKI (Public Key Infrastructure) certificate based authentication of both the
client and authentication server.

down list.
Identity: Enter the user name.
Password: Enter the password.
Click on the OK button to save the changes.
802.1x CA Server
Depending on the EAP in use, only the server or both the server and client may
be authenticated and require a certificate. Server certificates identify a server,
usually an authentication or RADIUS server to clients. Most EAPs require a
certificate issued by a root authority or a trusted commercial Certificate Authority.
Use certificate chain: Place a check in this to enable the certificate use.
Certificate issuer: Select the Certification Authority from the drop-down list.
Allow intermediate certificates: During tunnel creation the client must
verify the server’s certificate. When checking this certificate the signature
is verified against a list of trusted certificate authorities. If this parameter is
true then the client will also accept a signature from a trusted intermediate
22
certificate authority, otherwise it will not.
Server name: Enter the server name if not selected from the existing drop-
down list above.
Click on the OK button to save the changes.

data transmission more secure. You may select 64 or 128-bit WEP (Wired
Equivalent Privacy) key to encrypt data (Default setting is Disable). WEP
encrypts each frame transmitted from the radio using one of the Keys from a
panel. When you use WEP to communicate with the other wireless clients, all the
wireless devices in this network must have the same encryption key or pass
phrase. The following information is included in this tab, as the image depicts
below.
Authentication Type: Select Open or Shared from the drop-down list.
Encryption: Select WEP from the drop-down list.
WEP Key: Type a character string into the field. For 64-bit enter 5

WPA-PSK Authentication & TKIP, AES Encryption
WPA – PSK (Pre-shared Key) is used in a Pre Shared Key mode that does not
require an authentication server. Access to the Internet and the rest of the
wireless network services is allowed only if the pre-shared key of the computer
matches that of the Access Point. This approach offers the simplicity of the WEP
key, but uses stronger TKIP encryption. EAP (Extensible Authentication Protocol)
is an extension to the PPP protocol that enables a variety of authentication
protocols to be used. It passes through the exchange of authentication messages,
allowing the authentication software stored in a server to interact with its
counterpart in the client.
Authentication Type: Select WPA or WPA2 from the drop-down list.
Encryption: Select TKIP or AES from the drop-down list.
WPA Preshared key: Enter a pass phrase which is between 8 and 32
characters long.
