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 IEEE802.11, and generally, the smaller the
value in the window, the higher the probability that the queue
obtains the right to send.
AIFSN
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.
