The following settings are available:
Transmit Power Level
Choose a transmitting power level, from the minimum 10%, to the
maximum, 100%. Use it to transmit at the lower level. The value is set
automatically in response to a notice from the access point.
802.11b Preamble
The default setting is Short&long. This setting is included for
compatibility with the old access points, which do not accept a long
preamble.
Enable QoS
Select this check box if you need to set the priority when transmitting
data such as video stream.
Power save mode
You can adjust the power saving mode in three stages. The mode can
be set for each location profile.
Preferred Access Point MAC Addresses
If you specify a MAC address for the access point, the connection will
be made only to that address. If you do not specify a MAC address,
the system will find an SSID automatically and connect to that SSID.
Contact your network administrator for the appropriate settings.
