•The Ad-hoclets users set a small wireless workgroup easily and quickly. Equipped with the Wireless LAN USB Adapter, users can share files and printers between each PC and laptop.

Tx Power: Transmit power, the amount of power used by a radio transceiver to send the signal out. Select the Tx power percentage from the pull-down list including Auto, 100%, 75%, 50%, 25%, 10% and

Lowest.

Preamble: This function will show up when Ad-hoc network type be selected. A preamble is a signal used in wireless environment to synchronize the transmitting timing including Synchronization and Start frame delimiter. Select from the pull-down menu to change the Preamble type into Auto or Long.

Power Save Mode:

•CAM (Constantly Awake Mode): When this mode is selected, the power supply will be normally provided even when there is no throughput. (Default power save mode is CAM.)

•PSM (Power Saving Mode): When this mode is selected, this device will stay in power saving mode even when there is high volume of throughput.

RTS Threshold: Users can adjust the RTS threshold number by sliding the bar or key in the value directly. (The default value is 2347.) RTS/CTS Threshold is a mechanism implemented to prevent the “Hidden Node” problem. If the “Hidden Node” problem is an issue, users have to specify the packet size. The RTS/CTS mechanism will be activated if the data size exceeds the values that have been set.

This value should remain at its default setting of 2347. Should users encounter inconsistent data flow, only minor modifications of this value are recommended.

Fragment Threshold: Users can adjust the Fragment threshold number by sliding the bar or key in the value directly. (The default value is 2346.) The mechanism of Fragmentation Threshold is used to improve the efficiency when high traffic flows along in the wireless network. If the Wireless LAN USB Adapter often transmits large files in wireless network, users can enter new Fragment Threshold value to split the packet. The value can be set from 256 to 2346.

Authentication and Security tab:

Authentication Type: There are several types of authentication modes including Open, Shared, Leap, WPA, WPA-PSK, WPA2 and WPA2-PSK.

•Open: If the access point or wireless router is using "Open” authentication, then the Wireless LAN USB Adapter will need to be set to the same authentication type.
