Chapter I: Introduction
Thank you for purchasing the 802.11g Wireless LAN PCI Card. This card complies with IEEE 802.11g
standard, which supports up to 54Mbps high-speed wireless network connections. It can also work with
IEEE 802.11b devices. When the card connects to 11b devices, the link speed will be up to 11Mbps.
This card enables higher data throughput than the IEEE 802.11g standard (up to 54Mbps). It supports
specific ways to increase the data transfer rate at a time; compress the data and decrease the waiting
time to send the next data to the Routers or APs. This feature is called Turbo Mode. When the card is
connecting to the Routers or APs with the proprietary Turbo Mode feature, the wireless network will be
more effective.
For WLAN security issues, this card supports 64/128-bit WEP data encryption that protects your
wireless network from eavesdropping. It also supports WPA (Wi-Fi Protected Access) feature that
combines IEEE 802.1x and TKIP (Temporal Key Integrity Protocol) technologies. Client users are
required to authorize before accessing to APs or AP Routers, and the data transmitted in the network is
encrypted/decrypted by a dynamically changed secret key. Furthermore, this card supports WPA2
function, WPA2 provides a stronger encryption mechanism through AES (Advanced Encryption
Standard), which is a requirement for some corporate and government users.
When you use the devices such as Voice over Internet Protocol (VoIP) phones, televisions, VCRs and
MP3 players, how can you speed up the audio, video and voice data to pass through the wireless
network? IEEE 802.11e Quality of Service (QoS) (The Wi-Fi Alliance defined WMM as a profile of the
IEEE 802.11e) extensions for 802.11 networks will help to define the priorities of the data traffics by the
data categories to provide enhanced multimedia support. This card supports the advanced technology
for sure.
The power consumption of the card is also very low. This card provides several levels of power saving
modes allowing user customizes the way of saving the power from his/her portable or handheld
devices.

mode.
PSM (Power Saving Mode) – Enable the card in the power saving
mode when it is idle.
Network Type Infrastructure – This operation mode requires the presence of an
802.11 Access Point. All communication is done via the Access Point or
Router.
Ad-Hoc – Select this mode if you want to connect to another wireless
stations in the Wireless LAN network without through an Access Point
or Router.
TX Power If you want to lower the transmit power of the card for saving the power
of the system, you can select the lower percentages from the list. The
lower power will cause the lower signal strength and the coverage
range.
Ad Hoc Wireless Mode When the card is set in Ad Hoc (Peer to Peer Mode), you can designate
the wireless connection mode for the Ad Hoc network.
802.11 B only – This card can be compatible with both 802.11g and
802.11b wireless stations. If there are only 802.11b wireless stations in
the network, you can set the card to this mode.
802.11 B/G mix – If you have a mix of 802.11b and 802.11g wireless
stations in your network, it is recommended to setting the card to this
mode. This mode is also the default setting.
802.11 G only – This card can be compatible with both 802.11g and
802.11b wireless stations. If there are only 802.11g wireless stations in
the network, you can set the card to this mode.
Preamble
AirLive WT-2000USB User’s Manual
The preamble defines the length of the CRC block for communication
16
among wireless devices. This option is only active in the Ad Hoc
network.
There are two modes including Auto and Long Preamble. If
“Auto“ mode is selected, the card will auto switch the preamble mode
depending on the wireless devices the card is connecting to.
Parameter Description
RTS Threshold Minimum packet size required for an RTS (Request To Send). For
packets smaller than this threshold, an RTS is not sent and the packet
is transmitted directly to the wireless network. Select a setting within a
range of 0 to 2347 bytes. Minor change is recommended.
Fragment Threshold The value defines the maximum size of packets; any packet size larger
than the value will be fragmented. If you have decreased this value and
experience high packet error rates, you can increase it again, but it will
likely decrease overall network performance. Select a setting within a
range of 256 to 2346 bytes. Minor change is recommended.
Channel This setting is only available for Ad Hoc mode. Select the number of the
radio channel used for the networking. The channel setting should be
the same with the network you are connecting to.

AirLive WL-1000CAM User’s Manual
3.2.1.2 Authentication and Security
Parameter Description
Authentication Type This setting has to be consistent with the wireless networks that
the card intends to connect.
Open – No authentication is needed among the wireless network.
Shared – Only wireless devices using a shared key (WEP Key
identified) are allowed to connecting each other.
Parameter Description
Authentication Type LEAP – LEAP is a pre-EAP, Cisco-proprietary protocol, with many
of the features of EAP protocols. Cisco controls the ability of other
vendors to implement this protocol, so it should be selected for
use only when limited vendor choice for client, access-point, and
server products is not a concern. When you have set up LEAP
authentication, you have to enter the user name and password of
your computer.
WPA – WPA provides a scheme of mutual authentication using
either IEEE 802.1x/Extensible Authentication Protocol (EAP)
authentication or pre-shared key (PSK) technology. It provides a
high level of assurance to enterprises, small businesses and
home users that data will remain protected and that only
authorized users may access their networks. For enterprises that
have already deployed IEEE 802.1x authentication, WPA offers
the advantage of leveraging existing authentication databases
and infrastructure.
WPA-PSK – It is a special mode designed for home and small
business users who do not have access to network authentication
servers. In this mode, known as Pre-Shared Key, the user
manually enters the starting password in their access point or
gateway, as well as in each wireless stations in the network.
WPA-PSK takes over automatically from that point, keeping
unauthorized users that don't have the matching password from
joining the network, while encrypting the data traveling between
authorized devices.
WPA2 – Like WPA, WPA2 supports IEEE 802.1x/EAP
authentication or PSK technology. It also includes a new
advanced encryption mechanism using the Advanced Encryption
Standard (AES). AES is required to the corporate user or
government users. The difference between WPA and WPA2 is that
WPA2 provides data encryption via the AES. In contrast, WPA
uses Temporal Key Integrity Protocol (TKIP).
AirLive WT-2000USB User’s Manual
18
WPA2-PSK – WPA2-PSK is also for home and small business.
The difference between WPA-PSK and WPA2-PSK is that
WPA2-PSK provides data encryption via the AES. In contrast,
WPA-PSK uses Temporal Key Integrity Protocol (TKIP).
802.1x Setting When you have set the Authentication Type to Open, Shared,
WPA or WPA2, you can also enable IEEE 802.1x setting to use
the authentication server or certification server to authenticate
client users.
Parameter Description
Encryption Mode None – Disable the encryption mode.
WEP – Enable the WEP Data Encryption. When the item is
selected, you have to continue setting the WEP Encryption keys.
TKIP – TKIP (Temporal Key Integrity Protocol) changes the
temporal key every 10,000 packets (a packet is a kind of message
transmitted over a network.) This insures much greater security
than the standard WEP security.
AES – AES has been developed to ensure the highest degree of
security and authenticity for digital information and it is the most
advanced solution defined by IEEE 802.11i for the security in the
wireless network.
Note: All devices in the network should use the same encryption
method to ensure the communication.
WPA Pre-Shared Key The WPA-PSK key can be from 8 to 64 characters and can be
letters or numbers. This same key must be used on all of the
wireless stations in the network.
WEP Key
(Key1 ~ Key4)
The WEP keys are used to encrypt data transmitted in the
wireless network. There are two types of key length: 64-bit and
128-bit. Select the default encryption key from Key 1 to Key 4 by

AirLive WL-1000CAM User’s Manual
The IEEE 802.1X specification describes a protocol that can be used for authenticating both clients and
servers on a network. The authentication algorithms and methods are those provided by the Extensible
Authentication Protocol (EAP), a method of authentication that has been in use for a number of years
on networks that provide Point-to-Point Protocol (PPP) support as many internet service providers and
enterprises do.
When an AP acting as an authenticator detects a wireless station on the LAN, it sends an EAP-Request
for the user's identity to the device. (EAP, or the Extensible Authentication Protocol, is an authentication
protocol that runs before network layer protocols transmit data over the link.) In turn, the device
responds with its identity, and the AP relays this identity to an authentication server, which is typically
an external RADIUS server.

3.2.1.3 802.1x Setting-Certification
Parameter Description
Authentication Type The EAP authentication protocols this card has supported are
included as follows. This setting has to be consistent with the
wireless APs or Routers that the card intends to connect.
PEAP &TTLS – PEAP and TTLS are similar and easier than TLS
in that they specify a stand-alone authentication protocol be used
within an encrypted tunnel. TTLS supports any protocol within its
tunnel, including CHAP, MS-CHAP, MS-CHAPv2, PAP and
EAP-MD5. PEAP specifies that an EAP-compliant authentication
protocol must be used; this card supports EAP-MSCHAP v2,
EAP-TLS/Smart card and Generic Token Card. The client
certificate is optional required for the authentication.
TLS/Smart Card –TLS is the most secure of the EAP protocols
but not easy to use. It requires that digital certificates be
exchanged in the authentication phase. The server presents a
certificate to the client. After validating the server’s certificate, the
client presents a client certificate to the server for validation.
MD5-Challenge – MD5-Challenge is the easiest EAP Type. It
requires the wireless station to enter a set of user name and
password as the identity to RADIUS Server.
Session Resumption There are “Disabled”, “Reauthentication”, “Roaming”, “SameSsid”
and “Always” selections for you to choose whether to recovery the
session in different status.
Identity Enter the name as the identity for the server.
Password Enter the password as the identity for the server.
Use Client Certificate
client certificate is required for TLS, and is optional for TTLS and
PEAP. This forces a client certificate to be selected from the
appropriate Windows Certificate Store and made available to the
RADIUS server for certification.

Parameter Description
Enable TCP Window Size The TCP Window is the amount of data a sender can send on a
particular connection before it gets an acknowledgment back from
the receiver that it has gotten some of it. When the Router or AP
the card is connecting to have set up the TCP Window, you can
enable the parameter to meet the data size for the Router or AP
connection. The larger TCP Window the better performance.
Fast Roaming at -70dBm When you want to fast roaming to the network nearby without
intercepting the wireless connection especially the card is applied
to the multimedia application or a voice call, you can enable the
parameter. The card will fast roaming to the near network when
the receive sensitivity (signal strength) is lower to the value you
have set up.
Turn Off RF Button If you want to turn off the radio of the card temporarily, click this
button. To turn on the radio, click this button again.
CCX 2.0 CCX 2.0 (Cisco Compatible Extensions) is developed by Cisco for
the radio monitoring and fast roaming.
LEAP Turn on CCKM During normal operation, LEAP-enabled client devices mutually
authenticate with a new access point by performing a complete
LEAP authentication, including communication with the main
RADIUS server.
When you configure your wireless LAN for fast re-association,
however, LEAP-enabled client devices roam from one access
point to another without involving the main server. Using Cisco
Centralized Key Management (CCKM), an access point
configured to provide Wireless Domain Services (WDS) takes the
place of the RADIUS server and authenticates the client so
quickly that there is no perceptible delay in voice or other
time-sensitive applications.

Chapter IV: Troubleshooting
This chapter provides solutions to problems usually encountered during the installation and operation
of the adapter.
1. What is the IEEE 802.11g standard?
802.11g is the new IEEE standard for high-speed wireless LAN communications that provides
for up to 54 Mbps data rate in the 2.4 GHz band. 802.11g is quickly becoming the next
mainstream wireless LAN technology for the home, office and public networks.
802.11g defines the use of the same OFDM modulation technique specified in IEEE 802.11a
for the 5 GHz frequency band and applies it in the same 2.4 GHz frequency band as IEEE
802.11b. The 802.11g standard requires backward compatibility with 802.11b.
The standard specifically calls for:
A. A new physical layer for the 802.11 Medium Access Control (MAC) in the 2.4 GHz
frequency band, known as the extended rate PHY (ERP). The ERP adds OFDM as a
mandatory new coding scheme for 6, 12 and 24 Mbps (mandatory speeds), and 18, 36, 48
and 54 Mbps (optional speeds). The ERP includes the modulation schemes found in
802.11b including CCK for 11 and 5.5 Mbps and Barker code modulation for 2 and 1 Mbps.
B. A protection mechanism called RTS/CTS that governs how 802.11g devices and 802.11b
devices interoperate.
2. What is the IEEE 802.11b standard？
The IEEE 802.11b Wireless LAN standard subcommittee, which formulates the standard for the
industry. The objective is to enable wireless LAN hardware from different manufactures to
communicate.
3. What does IEEE 802.11 feature support？
The product supports the following IEEE 802.11 functions:
z CSMA/CA plus Acknowledge Protocol
z Multi-Channel Roaming
z Automatic Rate Selection
z RTS/CTS Feature
z Fragmentation
z Power Management
4. What is Ad-hoc？
An Ad-hoc integrated wireless LAN is a group of computers, each has a Wireless LAN adapter,
Connected as an independent wireless LAN. Ad hoc wireless LAN is applicable at a
departmental scale for a branch or SOHO operation.
5. What is Infrastructure？
An integrated wireless and wireless and wired LAN is called an Infrastructure configuration.
Infrastructure is applicable to enterprise scale for wireless access to central database, or
wireless application for mobile workers.
AirLive WL-1000CAM User’s Manual
31
6. What is BSS ID？
A specific Ad hoc LAN is called a Basic Service Set (BSS). Computers in a BSS must be
configured with the same BSS ID.
7. What is WEP？
WEP is Wired Equivalent Privacy, a data privacy mechanism based on a 40 bit shared key
algorithm, as described in the IEEE 802 .11 standard.
8. What is TKIP?
TKIP is a quick-fix method to quickly overcome the inherent weaknesses in WEP security,
especially the reuse of encryption keys. TKIP is involved in the IEEE 802.11i WLAN security
standard, and the specification might be officially released by early 2003.
9. What is AES?
AES (Advanced Encryption Standard), a chip-based security, has been developed to ensure
the highest degree of security and authenticity for digital information, wherever and however
communicated or stored, while making more efficient use of hardware and/or software than
previous encryption standards. It is also included in IEEE 802.11i standard. Compare with AES,
TKIP is a temporary protocol for replacing WEP security until manufacturers implement AES at
the hardware level.
10. Can Wireless products support printer sharing？
Wireless products perform the same function as LAN products. Therefore, Wireless products
can work with Netware, Windows 2000, or other LAN operating systems to support printer or
file sharing.
11. Would the information be intercepted while transmitting on air？
WLAN features two-fold protection in security. On the hardware side, as with Direct Sequence
Spread Spectrum technology, it has the inherent security feature of scrambling. On the
software side, WLAN series offer the encryption function (WEP) to enhance security and
Access Control. Users can set it up depending upon their needs.
12. What is DSSS？What is FHSS？And what are their differences？
Frequency-hopping spread-spectrum (FHSS) uses a narrowband carrier that changes
frequency in a pattern that is known to both transmitter and receiver. Properly synchronized,
the net effect is to maintain a single logical channel. To an unintended receiver, FHSS appears
to be short-duration impulse noise. Direct-sequence spread-spectrum (DSSS) generates a
redundant bit pattern for each bit to be transmitted. This bit pattern is called a chip (or chipping
code). The longer the chip is, the greater the probability that the original data can be recovered.
Even if one or more bits in the chip are damaged during transmission, statistical techniques
embedded in the radio can recover the original data without-the need for retransmission. To an
unintended receiver, DSSS appears as low power wideband noise and is rejected (ignored) by
most narrowband receivers.
AirLive WT-2000USB User’s Manual

13. What is Spread Spectrum？
Spread Spectrum technology is a wideband radio frequency technique developed by the
military for use in reliable, secure, mission-critical communication systems. It is designed to
trade off bandwidth efficiency for reliability, integrity, and security. In other words, more
bandwidth is consumed than in the case of narrowband transmission, but the trade off
produces a signal that is, in effect, louder and thus easier to detect, provided that the receiver
knows the parameters of the spread-spectrum signal being broadcast. If a receiver is not tuned
to the right frequency, a spread –spectrum signal looks like background noise. There are two
main alternatives, Direct Sequence Spread Spectrum (DSSS) and Frequency Hopping Spread
Spectrum (FHSS).
