Network Type
Infrastructure – Infrastructure means
to establish a connection with an access
point. Once connected, the access
point allows you to access wireless
LAN and wired LAN (Ethernet). The
Channel field turns to Auto if the
connection is based on Infrastructure.
Ad Hoc – Ad Hoc means to communicate directly with other wireless clients
without using an access point. An “Ad Hoc” network can be setup quickly
and easily without pre-planning, for example, sharing meeting notes between
attendants in a meeting room.
Network Name (SSID)
SSID stands for “Service Set Identifier”, which is a string used to identify a
wireless LAN. Use the SSID to connect with a known access point. You can
enter a new SSID or select one from the drop-down list box. If you get connected
by designating the SSID, you are only to connect the AP with the SSID you
assigned. If the AP is removed from the network, your WLAN Adapter does not
roam automatically to other APs. SSIDs must all be printable characters and
having a maximum of 32 case sensitive characters, such as “ Wireless”.
NOTE: Set the SSID to a null string, if you wish to allow your station to

Network Authentication
Since there is no precise bound in
wireless LANs, the WLAN users need
to implement certain mechanism
to provide security solution. The
Authentication policies in this tab
provide protection of different levels
such as Open, Shared, WPA-PSK,
WPA, and WPA2.
Open - Select this option to make the
network operate on Open System
mode, which use no authentication algorithm. Open stations and APs can
authenticate with each other without checking any WEP Key, even if there is.
Shared - Select this option to make the network operate on Shared key mode.
In a Share Key Authentication system, four-step exchange of frames is required
to validate that the station is using the same WEP Key as the access point.
WPA-PSK/ WPA2-PSK - Select this option to enable WPA Pre-Shared Key
under Infrastructure mode. It enables communication between your client and
APs using WPA-PSK/WPA2-PSK encryption mode.
WPA/ WPA2 - The network is operating in IEEE 802.1x authentication mode.
This mode is for environments with RADIUS (Remote Access Dial-in User
Service). In a RADIUS environment, three Extensible Authentication Protocol
(EAP) are supported, including PEAP, EPA/TLS, and LEAP.
&RQÀJ(QFU\SWLRQ
This page enables you to configure the Wireless LAN Adapter encryption
settings. For data confidentiality in a wireless environment, IEEE 802.11
specifies a Wired Equivalent Privacy (WEP) algorithm to offer transmission
privacy. The WEP uses keys to encrypt and decrypt data packets. The
encryption process can scramble frame bits to avoid disclosure to others. The
WPA/WPA2 is improved security system for 802.11 which are developed to
overcome the weakness of the WEP protocol.

encryption and Advanced Encryption Standard (AES) encryption are supported.
Disabled - Disable the encryption function.
WEP - WEP Key is used to encrypt your data before it is transmitted over air.
You can only connect and communicate with wireless devices that use the
same WEP keys.
TKIP - TKIP uses an encryption algorithm methods which is more stringent
than the WEP algorithm. It also uses existing WLAN calculation facilities to

64/128bits versus 40/104bits
There are two levels of WEP Encryption: 64 bits and 128 bits.
Firstly, 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

as 64 bits. Our Wireless LAN products use the term 64 bits when referring to
this lower level of encryption.
Secondly, 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

environment around the WLAN Adapter away from microwave ovens and large
metal objects. Then try to reorient the WLAN Adapter antenna. Second is the
distance, decrease the distance between your WLAN Adapter and the access
point or station (or another WLAN Adapter).

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

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.
ASUS WLAN Adapter 31
Chapter 5
Chapter 5 - Glossary
Glossary
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.
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-

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
