WMM

Set priorities for specific communications here.
You don't usually need to change these settings. Using the default settings is recommended.
Priority
The following priorities may be applied to individual transmission packets: (Highest) 8, (High) 4,
(Normal) 2, and (Low) 1. From the queue, these packets are processed in order of priority.
CWmin, CWmax
The maximum and minimum value of the contention window. The contention window is used
in the frame collision avoidance structure performed in IEEE 802.11, and generally, the smaller
the value in the window, the higher the probability that the queue obtains the right to send.
WMM-EDCA
AIFSN
Parameters
The interval to send frames. The unit of the AIFSN is a slot, just as the window defined by
CWmin and CWmax is. The smaller the interval of sending frames, the faster the algorithm can
restart. As a result, the priority of the queue is higher.
TXOP Limit
The period of time that the queue can use after obtaining the right to send. The unit is 32 ms.
The longer this time, the more frames can be sent per right to send. However, the queue may
interfere with other packet transmissions. If TXOP limit is set to 0 (zero), only one frame can be
sent per right to send.
