This page enables you to change the Network
adapter configurations.
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 Network 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 Channel field is for setting radio channel. Your Network adapter can automatically
select the correct channel to communicate with a wireless device, and the parameter is
fixed 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 14 are
supported.
Note: Click Apply to save and activate the new configurations.

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.

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
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.
•
28
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.

Chapter 4: Using the ASUS WLAN Control Center
•
•
•
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.
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.
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.
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:
•
•
•
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.
Config - Advanced
Click Advanced link on Config-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 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.
