used by wireless signals from the device) –
the recommended value is 20/40/80MHz.

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.
WMM WMM (Wi-Fi Multimedia) technology can
improve the performance of certain network
applications, such as audio/video streaming,
network telephony (VoIP) and others. When
WMM is enabled, the device will prioritize
different kinds of data and give higher
priority to applications which require instant
responses for better performance.
