Cong - Basic
This page enables you to change the WLAN
Adapter congurations.
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 eld 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 Identier”, 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”.
Channel
The Channeleld is for setting radio channel. Your WLAN Adapter can
automatically select the correct channel to communicate with a wireless device,
and the parameter is xed to "Auto" in both Infrastructure and Ad Hoc mode.
The available radio channels depend on the regulations in your country. For
the United States (FCC) and Canada (IC), channel 1 to 11 are supported. For
Europe (ETSI), channel 1 to 13 are supported. For Japan (MKK), channel 1 to

Cong - Advanced
Click Advanced link on Cong-Basic page to
show this tab. This tab allows you to set up
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 specic 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 specic 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 efciency and boosts
throughput.
PS Mode
Constantly Awake Mode (CAM), also known as Disable Power Saving Mode,
is a full powered state that yields the best performance. We recommend this
mode for devices running on AC power.
Power Saving Polling Mode (PSP Mode), which is also known as Enable
Power Saving mode, periodically wakes up the system to check if there is any
data being sent. We recommend this mode for devices running on battery
power.

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, WPA2 and WPA2-
PSK.
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, ve Extensible Authentication Protocol
(EAP) are supported, including PEAP, TLS/Smart Card, TTLS, LEAP and Md5-
Challenge.
Cong - Encryption
This page enables you to congure the Wireless LAN Adapter encryption
settings. For data condentiality in a wireless environment, IEEE 802.11
species 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.

Data encryption
For Open and Shared authentication mode, the conguration 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.
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 veries the security conguration 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 led as encryption mode to
begin the encryption proceed. Note: 8 to 64 characters are required in this eld.
Wireless Network Key (WEP)
This option is congurable only if you enable WEP in Network Authentication
eld. 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 dening 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 theeld 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 eld 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.
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.

Cong - Authentication
This tab allows you to set the security settings to match those of your AP. It is
congurable only if you have set Network Authentication to WPA or WPA2 in
Cong-Encryption tab.
Authentication Type
The authentication type methods include:
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 certicates to verify the identity of a client and server.
TTLS: TTLS authentication uses certicates to authenticate the server, while
maintaining similar security properties to TLS such as mutual authentication
and a shared condentiality 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.
