• The infrastructure is intended for the connection
between wireless network cards and an Access Point.
With the wireless adapter, you can connect wireless
LAN to a wired global network via an Access Point.
Tx Power: Select the Tx power percentage from the
pull-down list including Auto, 100%, 75%, 50%, 25%,
10% and Lowest.
Preamble: 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.
RTS Threshold: User 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 you set.
This value should remain at its default setting of 2347.
Should you encounter inconsistent data flow, only minor
modifications of this value are recommended.
Fragment Threshold: User 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 your Wireless LAN Adapter often transmits
large files in wireless network, you can enter new
Fragment Threshold value to split the packet. The value
can be set from 256 to 2346.
