WMM
Encryption
will not be visible as an available Wi-Fi
network to clients – clients must manually
enter the SSID in order to connect. A hidden
SSID is typically more secure than a visible
SSID.
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.
Select an encryption type from the
drop-down menu:
"WPA Pre-shared Key" is the
recommended and most secure
encryption type.
In WISP mode, WPA RADIUS is
unavailable for the wireless
band that is used to connect to
WISP's AP.
