WMM (Wi-Fi Multimedia) — Select whether to enable or disable WMM. The WMM
feature enhances the Quality of Service (QoS) of a network that is used by
multimedia applications such as Voice-over-IP (VoIP) and video. If WMM is enabled,
multimedia applications on your network have priority over regular data packets,
allowing multimedia applications to run smoother and with fewer errors.
WMM APSD — If WMM is enabled, you can also select whether to enable or disable
WMM APSD (Automatic Power Save Delivery). APSD manages radio usage for
battery-powered devices to allow longer battery life in certain conditions.
Fragment Threshold — Fragment threshold refers to the maximum size of a packet
before data is fragmented into multiple packets. The default and recommended
value is 2346 bytes. If you experience a high packet error rate, you may slightly adjust
the value. Setting the fragment threshold too low may result in poor network
performance.
RTS Threshold — The default and recommended value is 2347. Should you encounter
inconsistent data flow, only slight modifications should be made.
Beacon Interval — Enter a value in milliseconds. A beacon is a packet that is sent out
by the Wireless Gateway to synchronize the wireless network. The beacon interval
value indicates the frequency interval of the beacon. The default value is 100.
