This device complies with FCC Rules Part 15. Operation is subject to the following
two conditions:
• This device may not cause harmful interference, and
• This device must accept any interference received, including interference that
may cause undesired operation.
This equipment has been tested and found to comply with the limits for a class
B digital device pursuant to part 15 of the FCC Rules. These limits are designed
to provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may cause
harmful interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined
by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
WARNING: Any changes or modications not expressly approved by the party
responsible for compliance could void the user’s authority to operate the

Action mode name & Network Name (SSID) - Key in or select from the dropdown
list the SSID of an AP or station you are trying to connect to. An SSID must be valid
characters and have a maximum of 32 case sensitive characters, such as Wireless
LAN.

Conguration - Encryption
The Encryption page allows you to set
up the encryption settings for your WLAN
adapter For data condentiality in a wireless
environment, IEEE 802.11 species a Wired
Equivalent Privacy (WEP) algorithm to
offer transmission privacy similar to wired
network. WEP uses keys to encrypt data
packets sent and decrypt data packets
received. The encryption process can
scramble frame bits to avoid disclosure to others. Wi-Fi Protected Access (WPA) is
an improved security system for 802.11 that encrypts data sent over radio waves.
WPA is developed to overcome the weakness of the WEP protocol.
Network Authentication - Set up authentication for your WLAN adapter. Options
are:
Open - Sets the network in the Open System mode that disables authentication
protection for the network or use the WEP encryption for the network.
Shared - Sets the network in the Shared Key mode that uses the WEP
encryption for your network.
WPA-PSK/WPA2-PSK - Use the WPA Pre-Shared Key/WPA2 Pre-Shared Key
in the Infrastructure mode for authentication.
Data Encryption - In the Open and Shared authentication modes, options are:
Disabled and WEP.
Disabled - Disables the encryption protection for your WLAN adapter.
WEP - Encrypts the data before it is transmitted over the air. You can
communicate with wireless devices that use the same WEP keys.
In the WPA-PSK and WPA2-PSK authentication modes, options are: Temporal Key
Integrity Protocol (TKIP) and Advanced Encryption Standard (AES).
TKIP - Dynamically generates unique keys to encrypt data packet.
AES - Offers stronger protection and increases the complexity of wireless
encryption. It is a symmetric 128-bit block encryption method that works
simultaneously on multiple network layers.

ASUS Wireless-N Adapter
Wireless Network Key (WEP) - This option becomes congurable when you
select WEP in the Data encryption eld. 64-bit WEP key uses 5 ASCII characters
(10 hexadecimal digits). 128-bit WEP key uses 13 ASCII (26 hexadecimal digits).
Key Format - Allows you to select the key format.
Manual Assignment (WPA and WPA2)- Allows you to assign WEP Keys
manually.
Key Length - Allows you to select the key length. For 64bits encryption, each
key consists of 10 hexadecimal digits or 5 ASCII characters. For 128bits
encryption, each key consists of 26 hexadecimal digits or 13 ASCII characters.
Select one as your Default Key - Allows you to select one of the four WEP
Keys as the default key.
Conguration - Advanced
TheAdvanced page is intended for experienced
users to set up additional parameters for the
WLAN adapter. We recommend that you keep
the default values.
RTS Threshold (0-2347) - The Request to
Send/Clear to Send (RTS/CTS) 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 specic 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.
Preamble Mode - Select the preamble mode. The default value is Auto.
