frame delimiter. Select from the pull-down menu to change the Preamble

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 value 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 Encryption tab:
Authentication Type: There are six type of authentication modes
including Open, Shared, 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.
• Shared: Shared key is when both the sender and the recipient share a
secret key.
