Preamble Type Set the wireless radio preamble type. The
default value is “Short Preamble”.
CTS Protect Enabling this setting will reduce the chance
of radio signal collisions between 802.11b
and 802.11g wireless access points. It’s
recommended to set this option to “Auto”.
Tx Power Set the power output of the wireless radio.
You may not require 100% output power.
Setting a lower power output can enhance
security since potentially malicious/unknown
users in distant areas will not be able to
access your signal.
Tx power works in conjunction with the switch on the
underside of the device. The switch is the primary setting and
the Tx power value here will be a percentage of the slide
switch setting. E.G If the slide switch is set to Green Mode
(25%) and Tx power to 75%, the overall output will be 75% of
25%.
