• The Ad-hoc lets 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.
