before it is transmitted over the air.
If you enable WEP encryption, you will only be able to communicate with
wireless devices that have use the same WEP keys.
WEP Key
This option is enable only if you enable WEP Encryption. The WEP Key is a
64 bits (5 byte) or 128 bits (13 byte) Hexadecimal digits that is used to encrypt
transmit data packets and decrypt received data packets.
Key Format
You can enter the WEP Key as a Hexadecimal digits (0~9, a~f, and A~F), or as
ASCII characters, based on the state of the Key Format.

Key Length
For 64 bits encryption, each Key contains exactly 10 hex digits, or 5 ASCII
characters. For 128 bits encryption, each Key contains exactly 26 hex digits, or
13 ASCII characters.
Two ways to assign WEP keys
1. Manual Assignment - When you click this button, the cursor appears
in the field for Key 1. For 64-bit encryption, you are required to enter
four WEP Keys. Each Key contains exactly 10 hex digits (0~9, a~f, and
A~F). For 128-bit encryption, you are required to enter four WEP Keys.
Each Key contains exactly 26 hex digits (0~9, a~f, and A~F).
2. Automatic Generation - Type a combination of up to 64 letters, num-
bers, or symbols in the Passphrase column, then the Wireless Settings
Utility uses an algorithm to generate four WEP Keys for encryption.
NOTE: This function ease users from having to remember their
passwords and is compatible to some existing WLAN utilities, but
it is not very secure. "Manual Assignment" is more secure.
Default Key
The Default Key field lets you specify which of the four encryption keys you
use to transmit data on your wireless LAN. You can change the default key by
clicking on the down arrow at the right of this field, selecting the number of the
key you want to use and then clicking the Apply button. As long as the Access
Point or station with which you are communicating has the same key in the
same position, you can use any of the keys as the default.
You then click the Apply button to create your encryption keys. After you click
the Apply button, the Wireless Settings Utility uses asterisks to mask your
keys.
NOTE: Click the Apply or OK button to save the encryption set-
tings. The keys you entered will be masked by asterisks.

64/128bits versus 40/104bits
You may be confused about configuring WEP encryption, especially when
using multiple wireless LAN products from different vendors. There are
two levels of WEP Encryption: 64 bits and 128 bits.
First, 64 bit WEP and 40 bit WEP are the same encryption method and can
interoperate in the wireless network. This lower level of WEP encryption
uses a 40 bit (10 Hex character) as a “secret key” (set by user), and a 24 bit
“Initialization Vector” (not under user control). This together makes 64
bits (40 + 24). Some vendors refer to this level of WEP as 40 bits and
others refer to this as 64 bits. ASUS WLAN products use the term 64 bits
when referring to this lower level of encryption.
Second, 104 bit WEP and 128 bit WEP are the same encryption method
and can interoperate in the wireless network. This higher level of WEP
encryption uses a 104 bit (26 Hex character) as a “secret key” (set by user),
and a 24 bit “Initialization Vector” (not under user control). This together
makes 128 bits (104 + 24). Some vendors refer to this level of WEP as 104
bits and others refer to this as 128 bits. ASUS WLAN products use the
term 128 bits when referring to this higher level of encryption.

Cannot connect to a Station (ASUS WLAN Card)
Follow the procedure below to configure your ASUS WLAN Card.
a. Verify that the “Network Type” is in “Ad Hoc” mode.
b. Verify that the “SSID” of your ASUS WLAN Card is set to the same
“SSID” of the other station (or another ASUS WLAN Card).
c. Verify that the “channel” of the ASUS WLAN Card is “Auto” or set to
the same “channel” of the other station (or another ASUS WLAN Card).
d. Verify that the “Encryption” type is the same as the other station (or
another ASUS WLAN Card). If “WEP” encryption is enabled, you
must set the same “WEP” Keys on both stations.
Bad link quality or bad signal strength
There are two possible reasons. First is radio interference, keep the environment
around the ASUS WLAN Card away from microwave ovens and large metal
objects. Then try to reorient the ASUS WLAN Card antenna. Second is the
distance, decrease the distance between your ASUS WLAN Card and the Access
Point or station (or another ASUS WLAN Card).
The TCP/IP protocol did not bind to the ASUS WLAN PC Card.
This will occur when the computer already has six TCP/IP bindings in Windows
98 or ten bindings in Windows Me. These limits are imposed by the Microsoft
operating system.
Solution: If your computer already has the maximum number of TCP/IP
bindings, remove one of the network adapters from the Network configuration
before installing the ASUS WLAN Card driver.

Access Point (AP)
An networking device that seamlessly connects wired and wireless networks. Access
Points combined with a distributed system support the creation of multiple radio cells
that enable roaming throughout a facility.
Ad Hoc
A wireless network composed solely of stations within mutual communication range
of each other (no Access Point).
Basic Rate Set
This option allows you to specify the data transmission rate.
Basic Service Area (BSS)
A set of stations controlled by a single coordination function.
Broadband
A type of data transmission in which a single medium (such as cable) carries
several channels of data at once.
Channel
An instance of medium use for the purpose of passing protocol data units that may be
used simultaneously, in the same volume of space, with other instances of medium use
(on other channels) by other instances of the same physical layer, with an acceptably
low frame error ratio due to mutual interference.
Client
A client is the desktop or mobile PC that is connected to your network.
COFDM (for 802.11a or 802.11g)
Signal power alone is not enough to maintain 802.11b-like distances in an 802.11a/g
environment. To compensate, a new physical-layer encoding technology was designed
that departs from the traditional direct-sequence technology being deployed today. This
technology is called COFDM (coded OFDM). COFDM was developed specifically
for indoor wireless use and offers performance much superior to that of spread-spectrum
solutions. COFDM works by breaking one high-speed data carrier into several lower-
speed subcarriers, which are then transmitted in parallel. Each high-speed carrier is 20
MHz wide and is broken up into 52 subchannels, each approximately 300 KHz wide.
COFDM uses 48 of these subchannels for data, while the remaining four are used for
error correction. COFDM delivers higher data rates and a high degree of multipath
reflection recovery, thanks to its encoding scheme and error correction.
62 ASUS WLAN Card
Chapter 5
Chapter 5 - Glossary
Glossary
Each subchannel in the COFDM implementation is about 300 KHz wide. At the low
end of the speed gradient, BPSK (binary phase shift keying) is used to encode 125
Kbps of data per channel, resulting in a 6,000-Kbps, or 6 Mbps, data rate. Using
quadrature phase shift keying, you can double the amount of data encoded to 250 Kbps
per channel, yielding a 12-Mbps data rate. And by using 16-level quadrature amplitude
modulation encoding 4 bits per hertz, you can achieve a data rate of 24 Mbps. The
802.11a/g standard specifies that all 802.11a/g-compliant products must support these
basic data rates. The standard also lets the vendor extend the modulation scheme beyond
24 Mbps. Remember, the more bits per cycle (hertz) that are encoded, the more
susceptible the signal will be to interference and fading, and ultimately, the shorter the
range, unless power output is increased.
Default Key
This option allows you to select the default WEP key. This option allows you
to use WEP keys without having to remember or write them down. The WEP
keys generated using the Pass Phrase is compatible with other ASUS WLAN
products. The Pass Phrase option is not as secure as manual assignment.
Device Name
Also known as DHCP client ID or network name. Sometimes provided by an
ISP when using DHCP to assign addresses.
DHCP (Dynamic Host Configuration Protocol)
This protocol allows a computer (or many computers on your network) to be
automatically assigned a single IP address from a DHCP server.
DNS Server Address (Domain Name System)
DNS allows Internet host computers to have a domain name and one or more IP
addresses. A DNS server keeps a database of host computers and their respective domain
names and IP addresses, so that when a user enters a domain name into the Internet
browser, the user is sent to the proper IP address. The DNS server address used by the
computers on your home network is the location of the DNS server your ISP has assigned.
DSL Modem (Digital Subscriber Line)
A DSL modem uses your existing phone lines to transmit data at high speeds.
Direct-Sequence Spread Spectrum (for 802.11b)
Spread spectrum (broadband) uses a narrowband signal to spread the transmission over
a segment of the radio frequency band or spectrum. Direct-sequence is a spread spectrum
technique where the transmitted signal is spread over a particular frequency range.
Direct-sequence systems communicate by continuously transmitting a redundant pattern
of bits called a chipping sequence. Each bit of transmitted data is mapped into chips
and rearranged into a pseudorandom spreading code to form the chipping sequence.
The chipping sequence is combined with a transmitted data stream to produce the
output signal.
ASUS WLAN Card 63
Chapter 5
Chapter 5 - Glossary
Glossary
Wireless mobile clients receiving a direct-sequence transmission use the spreading
code to map the chips within the chipping sequence back into bits to recreate the original
data transmitted by the wireless device. Intercepting and decoding a direct-sequence
transmission requires a predefined algorithm to associate the spreading code used by
the transmitting wireless device to the receiving wireless mobile client.
This algorithm is established by IEEE 802.11b specifications. The bit redundancy within
the chipping sequence enables the receiving wireless mobile client to recreate the original
data pattern, even if bits in the chipping sequence are corrupted by interference. The
ratio of chips per bit is called the spreading ratio. A high spreading ratio increases the
resistance of the signal to interference. A low spreading ratio increases the bandwidth
available to the user. The wireless device uses a constant chip rate of 11Mchips/s for all
data rates, but uses different modulation schemes to encode more bits per chip at the
higher data rates. The wireless device is capable of an 11 Mbps data transmission rate,
but the coverage area is less than a 1 or 2 Mbps wireless device since coverage area
decreases as bandwidth increases.
Encryption
This provides wireless data transmissions with a level of security. This option allows
you to specify a 64-bit or a 128-bit WEP key. A 64-bit encryption contains 10 hexadecimal
digits or 5 ASCII characters. A 128-bit encryption contains 26 hexadecimal digits or 13
ASCII characters.
64-bit and 40-bit WEP keys use the same encryption method and can interoperate on
wireless networks. This lower level of WEP encryption uses a 40-bit (10 hexadecimal
digits assigned by the user) secret key and a 24-bit Initialization Vector assigned by the
device. 104-bit and 128-bit WEP keys use the same encryption method.
All wireless clients in a network must have identical WEP keys with the access point to
establish connection. Keep a record of the WEP encryption keys.
Extended Service Set (ESS)
A set of one or more interconnected basic service set (BSSs) and integrated
local area networks (LANs) can be configured as an Extended Service Set.
ESSID (Extended Service Set Identifier)
You must have the same ESSID entered into the gateway and each of its wireless
clients. The ESSID is a unique identifier for your wireless network.
Ethernet
The most widely used LAN access method, which is defined by the IEEE 802.3 standard.
Ethernet is normally a shared media LAN meaning all devices on the network segment
share total bandwidth. Ethernet networks operate at 10Mbps using CSMA/CD to run
over 10-BaseT cables.

IEEE
The Institute of Electrical and Electronics Engineers. The IEEE sets standards for
networking, including Ethernet LANs. IEEE standards ensure interoperability between
systems of the same type.
IEEE 802.11
IEEE 802.xx is a set of specifications for LANs from the Institute of Electrical and
Electronic Engineers (IEEE). Most wired networks conform to 802.3, the specification
for CSMA/CD based Ethernet networks or 802.5, the specification for token ring
networks. 802.11 defines the standard for wireless LANs encompassing three
incompatible (non-interoperable) technologies: Frequency Hopping Spread Spectrum
(FHSS), Direct Sequence Spread Spectrum (DSSS), and Infrared. 802.11 specifies a
carrier sense media access control and physical layer specifications for 1 and 2 Mbps
wireless LANs.
IEEE 802.11a (54Mbits/sec)
Compared with 802.11b: The 802.11b standard was designed to operate in the 2.4-
GHz ISM (Industrial, Scientific and Medical) band using direct-sequence spread-
spectrum technology. The 802.11a standard, on the other hand, was designed to operate
in the more recently allocated 5-GHz UNII (Unlicensed National Information
Infrastructure) band. And unlike 802.11b, the 802.11a standard departs from the
traditional spread-spectrum technology, instead using a frequency division multiplexing
scheme that's intended to be friendlier to office environments.
The 802.11a standard, which supports data rates of up to 54 Mbps, is the Fast Ethernet
analog to 802.11b, which supports data rates of up to 11 Mbps. Like Ethernet and Fast
Ethernet, 802.11b and 802.11a use an identical MAC (Media Access Control). However,
while Fast Ethernet uses the same physical-layer encoding scheme as Ethernet (only
faster), 802.11a uses an entirely different encoding scheme, called OFDM (orthogonal
frequency division multiplexing).
The 802.11b spectrum is plagued by saturation from wireless phones, microwave ovens
and other emerging wireless technologies, such as Bluetooth. In contrast, 802.11a
spectrum is relatively free of interference.
ASUS WLAN Card 65
Chapter 5
Chapter 5 - Glossary
Glossary
The 802.11a standard gains some of its performance from the higher frequencies at
which it operates. The laws of information theory tie frequency, radiated power and
distance together in an inverse relationship. Thus, moving up to the 5-GHz spectrum
from 2.4 GHz will lead to shorter distances, given the same radiated power and encoding
scheme.
Compared with 802.11g: 802.11a is a standard for access points and radio NICs that
is ahead of 802.11g in the market by about six months. 802.11a operates in the 5GHz
frequency band with twelve separate non-overlapping channels. As a result, you can
have up to twelve access points set to different channels in the same area without them
interfering with each other. This makes access point channel assignment much easier
and significantly increases the throughput the wireless LAN can deliver within a given
area. In addition, RF interference is much less likely because of the less-crowded 5
GHz band.
IEEE 802.11b (11Mbits/sec)
In 1997, the Institute of Electrical and Electronics Engineers (IEEE) adopted the 802.11
standard for wireless devices operating in the 2.4 GHz frequency band. This standard
includes provisions for three radio technologies: direct sequence spread spectrum,
frequency hopping spread spectrum, and infrared. Devices that comply with the 802.11
standard operate at a data rate of either 1 or 2 Mbps.
In 1999, the IEEE created the 802.11b standard. 802.11b is essentially identical to the
802.11 standard except 802.11b provides for data rates of up to 11 Mbps for direct
sequence spread spectrum devices. Under 802.11b, direct sequence devices can operate
at 11 Mbps, 5.5 Mbps, 2 Mbps, or 1 Mbps. This provides interoperability with existing
802.11 direct sequence devices that operate only at 2 Mbps.
Direct sequence spread spectrum devices spread a radio signal over a range of
frequencies. The IEEE 802.11b specification allocates the 2.4 GHz frequency band
into 14 overlapping operating Channels. Each Channel corresponds to a different set of
frequencies.
IEEE 802.11g
802.11g is a new extension to 802.11b (used in majority of wireless LANs today) that
broadens 802.11b's data rates to 54 Mbps within the 2.4 GHz band using OFDM
(orthogonal frequency division multiplexing) technology. 802.11g allows backward
compatibility with 802.11b devices but only at 11 Mbps or lower, depending on the
range and presence of obstructions.
