The QoS Setting fields are the same for the 2.4 GHz and 5 GHz bands.
5. To change the default settings of the access point EDCA settings, enter the appropriate
information in the AP EDCA parameters fields.
The following access point Enhanced Distributed Channel Access (EDCA) parameters
affect traffic flowing from the access point to the client station:
• AIFS. The Arbitration Inter-Frame Spacing (AIFS) interval specifies, in milliseconds,
the wait time between data frames. Higher AIFS values mean higher priority to that
queue. Valid values for AIFS are 1 through 255.
• CwMin. The minimum contention window (CwMin) value specifies the upper limit (in
milliseconds) of a range from which the initial random back-off wait time is
determined. Decreasing this value increases the priority of the queue. The value for
CwMin must be lower than the value for CwMax. Valid values are 1, 3, 7, 15, 31, 63,
127, 255, 511, and 1024.
• CwMax. The maximum contention window (CwMax) value specifies (in milliseconds)
the upper limit for the doubling of the random back-off value. Decreasing this value
increases the priority of the queue. The value for CwMax must be higher than the
value for CwMin. Valid values are 1, 3, 7, 15, 31, 63, 127, 255, 511, and 1024.
• Max. Burst. (access point only) The maximum burst value specifies (in milliseconds)
the maximum burst length allowed for packet bursts on the wireless network. A packet
burst is a collection of multiple frames transmitted without header information.
