Wireless Adapter Utility Features
27
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.
