4. Configuration Utility
After the Configuration Utility has been installed, an icon will placed in the system tray when the WLAN CardBus
Adapter is inserted. Click the icon and the configuration utility will pop up.
The utility was six tabs: Profile, Link Status, Site Survey, Statistics Advance, and About. You should change all your
configuration settings for your WLAN CardBus adapter using this utility.
4.1 Using the configuration Utility
After the Configuration Utility has been installed, an icon will placed in the system tray when the WLAN CardBus
Adapter is inserted. Click the icon and the configuration utility will pop up.
The utility was six tabs: Profile, Link Status, Site Survey, Statistics Advance, and About. You should change all your
configuration settings for your WLAN CardBus adapter using this utility.

15
4.1.1 Profile
Specific different network profile settings used in various locations, such as your office, your home, the factory, or the
airport. In each profile, you can specify a network type, network name, WEP and security setting parameters required
for that operating location.
4.1.1.1 System Configuration Edit profile Network Type:
The column in Profile list from left to right is “Profile”、”SSID”、”Channel”、”Authentication”、”Encryption”and
“Network Type” .Click ACTIVATE to excuse the profile.

16
SSID: All wireless devices within the ESS or extended wireless LAN use the SSID. This can be any alphanumeric
value of up to 32 characters long. Use this to prevent cross communication between two or more WLAN in one area.
The SSID should be changed in order to provide some minimum security.
Channel: Shows the selected channel that is currently used. (Available channels depends on the country or region
you are located.)
Authentication: Defines authentication type of the wireless networks, including "Open System" and “Share Key”
authentication. The wireless adapter will need to be set to the same authentication type to communicate.
Encryption: Indicates your WEP (Wired Equivalent Privacy) settings. WEP encryption can be used to ensure the
security of your wireless network. If there is no Encryption exists, the column will show Not USE.
Network Type: The network type of the wireless network. An Ad-Hoc wireless LAN is a group of computers each
with wireless adapters, connected as an independent wireless LAN. An integrated wireless and wired LAN is called an
infrastructure configuration.

17
4.1.1.2 Edit Profile
To add a new location profile name or to rename, delete, or select an existing profile, click Edit. The Edit
Configurations screen appears as follows
Power Save Mode:
CAM: (Constant Awake Mode) CAM is the normal mode for desktop machines or other machines where power
consumption is not an issue. It keeps the radio powered up continuously, so there is little latency for responding to
messages.
Max_PSP: Maximum Power Save.
Fast_PSP: Fast Awake.
Network Type
The network type of the wireless network. An Ad-Hoc wireless LAN is a group of computers each with wireless
adapters, connected as an independent wireless LAN. An integrated wireless and wired LAN is called an infrastruc-
ture configuration.
Preamble Type
Preamble is the first sub-field of PPDU, which is the appropriate frame format for transmission to PHY (Physical
layer). There are two options, Short Preamble and Long Preamble. The Short Preamble option improves throughput
performance.

18
RTS Threshold: The RTS Threshold sets an upper threshold at which point the device will issue an RTS packet. The
RTS (Request To Send) packet is used for the purpose of avoiding data collisions on the wireless LAN. There are
several trade offs to consider when setting this parameter. Setting this parameter to a small value causes RTS packets
to be sent more often, consuming more of the available bandwidth, therefore reducing the apparent throughput of other
network packets. However, the more often RTS packets are sent, the quicker the system can recover from interference
or collisions. Refer to the IEEE 802.11 Standard for more information on the RTS/CTS mechanism.
Fragment Threshold: Fragment Threshold defines a threshold above, which the wireless packet will be split up, or
fragmented. For a fragmented packet, if transmission of part of it were to be interfered with, only the portion that was
successfully transmitted would need to be resent. Throughput will generally be lower for fragmented packets, since the
fixed packet overhead consumes a higher portion of the RF bandwidth.

19
4.1.1.3 Authentication & Security
Authentication Type: Defines authentication type of the wireless networks, including "Open System" and “Share Key”
authentication. The wireless adapter will need to be set to the same authentication type to communicate.
Open System: With this setting any station in the Wireless LAN can associate with an Access Point to receive and to
transmit data.
Share Key: Is when both the sender and recipient share a secret key. Both units use this key for an extended length of
time, sometimes indefinitely.
Encryption Type: Indicates your WEP (Wired Equivalent Privacy) settings. WEP is disabled by default.
WEP : WEP (Wired Equivalent Privacy) is an optional feature of the IEEE 802.11 standard that is used to ensure the
security of your wireless network.
No Encryption: No any encryption for security.
WEP Key:
Key 1 - Key 4: These four fields can be used to manually enter the encryption keys. This may be necessary if you wish
this node to match keys in a different vendor's product.

20
WEP Key length: The 64 or 128-bits Wired Equivalent Privacy Algorithm. You can decide the network key to be
encoded by ASCII characters or hexadecimal digitals. A key of 10 hexadecimal characters (0-9, A-F) is required if a
64-bit Key Length was selected. A key of 26 hexadecimal characters (0-9, A-F) is required if a 128-bit Key Length
was selected.
4.1.2 Link Status
You can see the below status:Status, Current Channel, Current TX Rate, throughput(Kbit/sec), Link Quality, Signal
Strength.
