additional parameters for the wireless Adapter.
We recommend using the default values for all
items in this window.
RTS Threshold (0-2347)
The RTS/CTS (Request to Send/Clear to Send) function is used to minimize
collisions among wireless stations. When RTS/CTS is enabled, the router
refrains from sending a data frame until another RTS/CTS handshake is
completed. Enable RTS/CTS by setting a specific packet size threshold. The
default value (2347) is recommended.
Fragmentation Threshold (256-2346)
Fragmentation is used to divide 802.11 frames into smaller pieces (fragments)
that are sent separately to the destination. Enable fragmentation by setting
a specific packet size threshold. If there is an excessive number of collisions
on the WLAN, experiment with different fragmentation values to increase the
reliability of frame transmissions. The default value (2346) is recommended for
normal use.
Frame Bursting
Frame Bursting technology improves wireless network efficiency and boosts
throughput.

ASUS WLAN Adapter
Chapter 3 - Software Reference
Config - Encryption
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.
Network Authentication
Chapter 3
Software Reference
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, WPA2 and WPA2PSK.
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, five Extensible Authentication Protocol
(EAP) are supported, including PEAP, TLS/Smart Card, TTLS, LEAP and Md5Challenge.
ASUS WLAN Adapter

Chapter 3 - Software Reference
Data encryption
For Open and Shared authentication mode, the configuration options of
encryption type are Disabled and WEP. For WPA, WPA-PSK, WPA2 and
WPA2-PSK authentication mode, Temporal Key Integrity Protocol (TKIP)
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.
Chapter 3
Software Reference
TKIP - TKIP uses an encryption algorithm method that is more stringent than
the WEP algorithm. It also uses existing WLAN calculation facilities to perform
encryption. TKIP verifies the security configuration after the encryption keys are
determined.
AES: AES is a symmetric 128-bit block encryption technique that works
simultaneously on multiple network layers.
Wireless Network Key
This option is enabled only if you select WPA-PSK or WPA2-PSK authentication
mode. Select “TKIP” or “AES” in the encryption filed as encryption mode to
begin the encryption proceed. Note: 8 to 64 characters are required in this field.
Wireless Network Key (WEP)
This option is configurable only if you enable WEP in Network Authentication
field. The WEP Key is a 64 bits (5 byte) or 128 bits (13 byte) Hexadecimal
digits which is used to encrypt and decrypt data packets.
Key Format
You can select to enter Hexadecimal digits (0~9, a~f, and A~F) or ASCII
characters to setup keys by defining the Key Format.
Key Length
For 64 bits encryption, each key contains 10 hex digits or 5 ASCII characters.
For 128 bits encryption, each key contains 26 hex digits or 13 ASCII characters.
Manual assign WEP keys - When you select this option, 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).

Select one as your Default Key
The Default Key field allows you specify which of the four encryption keys is to
use for transmitting data over wireless LAN. You can change the default key
by clicking on the downward arrow, selecting the number of the key you want
to use, and clicking the “Apply” button. If the access point or station with which
you are communicating uses the identical key by the same sequence, you can
use any of the keys as the default on your WLAN Adapter.
Click the “Apply” button after you have created the encryption keys, the
Wireless Settings Utility uses asterisks to mask your keys.
64/128bits versus 40/104bits
There are two levels of WEP Encryption: 64 bits and 128 bits.
Chapter 3
Software Reference
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
“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. 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
“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. Our Wireless LAN products use the term 128 bits when
referring to this higher level of encryption.

Config - Authentication
This tab allows you to set the security settings to match those of your AP. It is
configurable only if you have set Network Authentication to WPA or WPA2 in
Config-Encryption tab.
Authentication Type
The authentication type methods include:
Chapter 3
Software Reference
PEAP: PEAP (Protected Extensible
Authentication Protocol) authentication is a
version of Extensible Authentication Protocol
(EAP). EAP ensures mutual authentication
between a wireless client and a server that
resides at the network operations center.
TLS: TLS (Transport Layer Security) authentication is used to create an
encrypted tunnel and achieve server-side authentication in a manner similar
to Web server authentication using Secure Sockets Layer (SSL) protocol. This
method uses digital certificates to verify the identity of a client and server.
TTLS: TTLS authentication uses certificates to authenticate the server, while
maintaining similar security properties to TLS such as mutual authentication
and a shared confidentiality for session WEP key.
Survey - Site Survey
Use the Site Survey tab to view statistics on
the wireless networks available to the WLAN
adapter and their parameters.

SSID: The SSID of the available
networks.
Channel: The channel used by each

RSSI: The Received Signal Strength Indication (RSSI) transmitted by each
network. This information is helpful in determining which network to connect
to. The value is then normalized to a dBm value.
Security: Wireless network encryption information. All devices in
the network should use the same encryption method to ensure the
communication.
BSSID: The media access control (MAC) address of the access point or
the Basic Service Set ID of the Ad Hoc node.
NOTE: Some access points may disable SSID broadcast and hide
themselves from “Site Survey” or “Site Monitor”, however, you can
connect such AP if you know their SSID.
