4 Configuration Utility
The Configuration Utility is provided to allow you further customization of the WLAN LAN PCI adapter and your wireless network.
4.1 Using the configuration Utility
After the Configuration Utility has been installed, an icon will placed in the system tray when the WLAN PCI Adapter is inserted.
The utility is divided into five parts: Profile , Link State, Site Survey, Statistics, and about. You should change all your configuration
settings for your WLAN PCI Adapter using this utility and not with the Network Properties section in your Control Panel.
Click ACTIVATE to excuse the profile.
To add a new location profile name or to rename, delete, or select an existing profile, click Edit. The Edit Configurations
screen appears
4.1.1 Profile
Specifies 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

Network Type:
Ad Hoc: An Ad-Hoc wireless LAN is a group of computers each with wireless adapters, connected as an independent wireless LAN.
Infrastructure: An integrated wireless and wired LAN is called an infrastructure configuration.
SSID: All wireless devices within the ESS or extended wireless LAN use the SSID. This can be any alphanumeric value of up to 32 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.
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.
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.
