Profile Configuration: Encryption
Instead of WEP, Windows XP users can choose to enable WPA. For more information, see
WPA on the following page.
Parameter Description
Encryption Mode None – Disable WEP data encryption.
WEP – Enable WEP data encryption. If you enable
WEP, you also have to set the WEP Keys.
Authentication Open System – No authentication is needed.
Shared Key – Only wireless stations using a shared
WEP key are allowed to connect to each other.
Auto Switch – Switches the authentication
algorithm depending on the wireless networks that
the adapter is connecting to.
Encryption Key Select the default encryption key using the radio
buttons. Fill the text box by following the rules
below:
64-bit – Input a 10-digit Hex value (in the “A-F,” “a-
f” and “0-9” range) for each encryption key. For
example: “0123456aef”
128-bit – Input a 26-digit Hex value (in the “A-F”,
“a-f” and “0-9” range) for each encryption key. For
example: “01234567890123456789abcdef”
152-bit – Input a 32-digit Hex value (in the “A-F”,
“a-f” and “0-9” range) for each encryption key. For
example: “012345678901234567890abcdefabcdef“
Encryption Key Length Choose a key length. Longer key lengths provide
better security but lessen throughput.

10
WPA
Wi-Fi Protected Access (WPA) is a set of standards-based, interoperable security
enhancements that strongly increase encryption and authentication for wireless LAN
systems. The technical components of WPA include Temporal Key Integrity Protocol
(TKIP) for dynamic key exchange, and 802.1x for authentication.
WPA function is enabled in the following software systems only:
•Windows XP with Service Pack 1 and the Windows XP Support Patch for Wi-Fi
Protected Access program.
•Configure the card by wireless built-in utility (Wireless Zero Configuration).
1. Right-click the networking icon in your taskbar and select “View Available Wireless
Networks.”
2. Click Advanced.
3. From the Wireless Networks tab, click Configure.

11
WPA, continued
Parameter Description
Network Authentication Open – No authentication is needed.
Shared – Only wireless stations using a shared key
(WEP Key identified) are allowed to connect to
each other.
WPA – This mode is for enterprise users with an
authentication server (Radius Server), WPA-enabled
access point, and a WPA-enabled client. Once WPA
is enabled, all clients and access points on the
network must be WPA-enabled in order to access
the network.
WPA-PSK – This 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 PC on the wireless
network. WPA 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.
Data Encryption WEP – In WPA or WPA-PSK mode, WEP is also able
to be the encryption method for the transmission
data.
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. It is the most advanced
solution defined by IEEE 802.11i for security in
the wireless network.
Note: All devices in the network should use the same encryption method to ensure
communication.

12
Profile Configuration: Advanced
Parameter Description
Power Saving Disable – The card will always be in Active mode.
Enable (Fast) – The card will be in Power Saving
mode when idle, but some components remain
alive. In this mode, power consumption is greater
than Max mode.
Enable (Max) – The card will go into Power Saving
mode when idle.
Preamble Type Preamble Type defines the length of the CRC block
for communication among the wireless networks.
There are three modes: Long, Short, and Auto. High
network traffic areas should use the shorter
preamble type. If Auto is selected, the card will
automatically switch the preamble type depending
on the wireless network the card is connecting to.
Fragment Threshold The value defines the maximum size of packets.
Any packet larger than this value will be
fragmented. Select a setting in the range of 256 to
2346 bytes. Minor change is recommended.
RTS Threshold This value defines the minimum packet size needed
for an RTS (Request To Send). For packets smaller
than this value, an RTS is not sent and the packet is
transmitted directly to the wireless network. Select a
setting in the range of 0 to 2347 bytes. Minor
change is recommended.
Receive Antenna Define the receive antenna. If Diversity is
selected, the card will automatically switch to the
antenna with the highest signal strength.

13
Statistics
The Statistics screen gives you information about your network communication. You can
view the available statistic information with its Transfer counts (Tx Success, Tx Error)
and Throughput, and its Receiving counts (Rx success, Rx error) and Throughput. You
may reset the counters by pressing its Reset button.

Appendix A: Installation Considerations
•The adapter will work in 802.11b mode when in Ad Hoc mode (this is defined in the
802.11g wireless standards). To increase the data rate up to 54 Mbits/sec, please
follow the steps listed below:
a. Go to “Network Connections.”
b. Right-click “Wireless Network Connection” and select “Properties.”
c. From the pop-up screen, click “Configure.”
d. Click on the “Advanced” tab on the “Properties” screen.
e. Change the setting of “IBSS Originator Phy-Mode” from “802.11b” to “802.11g.”
There are some things to keep in mind when attempting to set up a wireless connection.
The wireless signal range can be limited by the number, location, thickness, and material
of ceilings, walls or similar that the signal must pass through. To maximize your wireless
range, keep the following considerations in mind:
•Try to minimize the number of walls, ceilings, and similar between your wireless
devices. Each wall or ceiling the signal must cross can reduce the signal range by
up to 90 feet (30m). Position your receiving devices so that the path between them is
as unobstructed as possible.
•The type of material the wireless signal must cross through also affects its range. A
solid metal door or concrete wall can decrease the signal’s range. Whenever possible,
position the adapters so that the signal can pass through drywall or open doors.
•Make sure that you are aware of the line the signal must take to travel between
devices. The angle that the signal is on as it travels through a door, wall, or ceiling
affects how thick the obstruction is. For example, if a wall is 1.5 feet thick and the
signal passes through it at a 45-degree angle, the signal must pass through 3 feet (1m)
of wall. At a 2-degree angle, the wall appears to be 42 feet (14m) thick. Always try to
position your devices so that the signal can travel at 90-degree angles.
•Electrical devices or appliances that generate RF noise (such as microwaves, electric
motors or computer monitors) can interfere with the wireless signal. Try to keep your
adapter at least 3-6 feet (1-2 m) away from these types of devices.

Glossary
802.11b: A family of IEEE-defined specifications for wireless networks. The 802.11b
standard supports data transfer rates up to 11 Mbits/sec in the 2.4 GHz band using DSSS
technology. Also known as WiFi.
802.11g: A family of IEEE-defined specifications for wireless networks. The 802.11g
standard supports data transfer rates up to 54 Mbit/sec in the 2.4GHz band using
OFDM technology. 802.11g is backwards-compatible with the slower 802.11b standard.
Access Point: See wireless access point.
Ad Hoc: A wireless computer-to-computer LAN. An Ad Hoc network can consist of two
devices with wireless adapters, and does not require a WAP, wireless router, or wireless
gateway. Also known as peer-to-peer mode.
BSS (Basic Service Set): In Infrastructure mode, a BSS consists of a Wireless Access Point
and the adapters associated with it.
DSSS (Direct Sequence Spread Spectrum): A transmission technology used as the basis
for 802.11b wireless transmissions. DSSS helps increase a signal’s resistance to
interference and allows for some data bit recovery.
Encryption: The transformation of data into encoded ciphertext to ensure data
transmission can not be accessed by users outside the network. Encryption uses an
encryption algorithm and encryption keys to encode and decode the information. See
also WEP.
Encryption Algorithm: A formula used to convert data from understandable “plaintext”
into encoded “ciphertext.” Each algorithm uses a key (a string of bits) to perform the
calculations. The larger the key (most are 64 or 128-bits in length), the more difficult to
break the code.
ESS (Extended Service Set): In Infrastructure mode, the ESS consists of two or more
BSSes in the same subnet.
IBSS (Independent Basic Service Set): In Ad Hoc mode, an IBSS consists of two or more
wireless devices that communicate directly and do not use a wireless access point.
Infrastructure: A network configuration that typically combines both wired and wireless
elements. Wireless devices communicate with a WAP in order to communicate with each
other and with the wired elements of the network.
IP Address (Internet Protocol Address): An assigned number used to identify a computer
on a network. An IP address consists of four numbers less than 255 separated by periods
(for example, 192.168.2.1).
LAN (Local Area Network): A group of computers and devices connected together in a
relatively small area (such as a house or an office).
MAC Address (Media Access Control Address): A unique serial number that identifies a
piece of hardware connected to a network.
OFDM (Orthagonal Frequent Division Multiplexing): An FDM modulation technique for
transmitting large amounts of digital data over a radio wave. OFDM splits a signal into
several narrowband channels at different frequencies.

17
Plug and Play: A set of specifications that allows a computer to automatically detect and
configure hardware devices. With Plug and Play computers, any new hardware device
that is connected to a computer will automatically be recognized without the user having
to tell the computer the device has been added.
SSID (Service Set Identifier): A name that uniquely identifies a WLAN. In order for
wireless devices to communicate with each other, they must have the same SSID.
Subnet: An identifiably separate part of a network that is interconnected with, but still
independent from, the rest of the network. Subnets can help improve network security
and performance and typically use a router.
Subnet Mask: A technique used by the IP protocol to filter messages into a particular
network segment or subnet. Subnet masks are expressed as four decimal numbers
between 0 and 255 separated by periods. (Example: 255.255.255.1) It is used to create
private IP addresses for use within a particular network. Also known as a network mask.
WAN (Wide Area Network): A network that connects computers in geographically
separated areas. The Internet is an example of a WAN.
WAP (Wireless Access Point): A networking device that seamlessly connects wired and
wireless networks. Used in Infrastructure networks, a wireless access point is capable of
connecting to an Ethernet network as well as an 802.11 network.
WEP (Wired Equivalent Protocol): A security protocol designed to provide a wireless
network with the same level of security as a wired LAN. WEP offers protection primarily
by encrypting the information that flows between adapters.
Wi-Fi: See 802.11b.
WLAN (Wireless Local Area Network): A local area network that transmits wirelessly
through the air, typically in an unlicensed frequency such as the 2.4GHz band.
