When the Maximum Contention Window size is reached, retries will
continue until a maximum number of retries allowed is reached.
Valid values for the cwmax are 1, 3, 7, 15, 31, 63, 127, 255, 511, or
1024. The value for cwmax must be higher than the value for cwmin.
For more information, see “Random Backoff and Minimum / Maximum
Contention Windows” on page 165.
Max. Burst Length
AP EDCA Parameter Only (The Max. Burst Length applies only to
traffic flowing from the access point to the client station.)
This 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.
The decreased overhead results in higher throughput and better
performance.
Valid values for maximum burst length are 0.0 through 999.9.
For more information, see “Packet Bursting for Better Performance” on
page 166.

Enabling/
Disabling Wi-Fi
Multimedia
By default, Wi-Fi MultiMedia (WMM) is enabled on the access point. With
WMM enabled, QoS prioritization and coordination of wireless medium
access is on. With WMM enabled, QoS settings on the AT-WA7400
Wireless Access Point control downstream traffic flowing from the access
point to client station (AP EDCA parameters) and the upstream traffic
flowing from the station to the access point (station EDCA parameters).
Disabling WMM deactivates QoS control of station EDCA parameters on
upstream traffic flowing from the station to the access point
With WMM disabled, you can still set some parameters on the
downstream traffic flowing from the access point to the client station (AP
EDCA parameters).
 To disable WMM extensions, click Disabled.
 To enable WMM extensions, click Enabled.
