Enable/Disable Wi-Fi Multimedia

By default, Wi-Fi MultiMedia (WMM) is enabled on the access point. With WMM enabled, QoS settings on the Professional Access Point control both downstream traffic flowing from the access point to client station (access point EDCA parameters) and upstream traffic flowing from the station to the access point (station EDCA parameters). Enabling WMM essentially activates station-to-access-point QoS control.

Disabling WMM will deactivates QoS control of "station EDCA parameters" on upstream traffic flowing from
