Chapter 5 Compex WLU108G Utility Features
Transmit Power Level
Specifies the wireless transmit power to be used. Reducing the power
level lowers the risk of interference with other nearby wireless devices and
conserves battery power but decreases radio range.
Power Save Mode (Only applicable to Infrastructure mode)
This feature reduces power consumption by the USB adapter to extend
the battery life of your notebook. There are 3 options for this mode:
Off
•
The power management is disabled and the card consumes full
power from the computer.
Normal
•
The driver turns off the power to the adapter for brief periods over
briefly spaced time intervals.
Maximum
•
The driver turns off power to the adapter for longer periods over
more widely spaced time intervals.
The guideline for choosing between the Normal and Maximum
options:
The USB adapter wakes up more often and responds sooner to
network requests in Normal mode than in Maximum mode; and the
Maximum mode consumes less power than Normal mode.
Network Type
Select either Infrastructure if you are connecting to the WLAN using an
access point or Ad-hoc if you are connecting directly to another
computer equipped with a wireless adapter.
802.11b Preamble
The preamble is part of the IEEE 802.11b physical layer specification. It is
mandatory for all 802.11b devices to support the long preamble format,
but they may optionally support the short preamble. This USB adapter
supports both the short and long preambles.
