WLAN Utility Setting
With the WLAN PCI Adapter utility, users can configure all the
functions provided by the WLAN Monitor Utility. Double-click the
utility icon that appearsin the taskbar.
The WLAN Monitor Utility includes four tabs: Configuration, Link
State, Security and Statistics.
Configuration
As you enter the Configuration screen, you will see the current setting
appears in the screen.
ØNetwork Type:
If you want to connect with Access Point, please set the mode as”
Infrastructure” mode. If you have more stations and just want to set
them as local network, please set the mode as ” Ad-Hoc” mode.

7
ØChannel:
It shows radio channel numbers that used forWLANnetworking.
The channel number can be setonly under the Ad-Hoc operation
mode. In Ad-Hoc mode stations, each station must have the same
channel numbers and SSID.
In Infrastructure mode, the WLAN PCI Adapter will automatically
detect the channel number of the Access Point.
ØSSID:
The SSID differentiates one WLAN group name from another; so all
access points and all devices attempting to connect to a specific
WLAN group name must use the same SSID. A device will not be
permitted to join the BSS unless it can provide the unique SSID.
If the SSID parameter is “ANY”, it will detect the strongest signal of
the wireless station.
ØData Rate:
You can choose one of the transmission rates as follows, 11Mbps,
5.5Mbps, 2Mbps, 1Mbps, and Auto. The Auto will automatically
detect the suitable linking transfer rate and auto fall back when the
signal is not too strong to transmit data, it will auto fall back from
11Mbps to 5.5Mbps, 2Mbps and 1 Mbps.
ØFragment Threshold:
Fragmentation Threshold is a way of transmitting the packets that will
be fragmented. Choose a setting within a range of 256 to 2432 bytes.
It is recommended to fragment the packet when the link quality is bad,
it is to prevent the wasting time of resending a long packet that is lost.

8
ØRTS:
The RTS/CTS Threshold is a station initiates the process by sending a
RTS frame,the other ends receives the RTS and responds with a CTS
frame,the station must receive a CTS frame before sending the data
frame. This is to prevent the collisions by each station. Choose a
setting within a range of 0 to 2432 bytes. It is recommend limiting a
long packet to prevent each station waiting too long to transmit a data.
ØPower Save:
To set your WLAN PCI Adapter as power saving mode, select
“CAM”, “Max”or “Fast”.
ØUse Short Preamble:
The usage of the preamble is to limit the packet size of the data to
transmit. It is recommended to choose the short preamble when the
link quality is bad, it is to prevent the wasting time of resending a long
packet that is lost.
When the setting is messy, press “Undo”button to recover to the last
setting, and press“Apply”to save the current setting.

Select WEP for data encryption or No Encryption.
ØAuth Algorithm:
Open System Authentication algorithm is mostly used. In Shard Key
Authentication algorithm, you must have security on, the algorithm
should be different, and some steps use packets with encryption by
transferring a challenge text. In order to choose which authentication
algorithm will be used, you must know which one the AP supports
first. Most AP only supportsOpen System.

12
ØKey Setting #1 ~ #4:
You can type the key that you want to use from Key#1 to Key #4, and
the key that you type will be the encryption between the station that
you connected with, if you select 64bit, youmusttype 10 values in the
