2. Click a tab to select a profile group.
3. Click a tab to select a radio.
This screen lets you modify the QoS settings per profile group and per radio for upstream
traffic flowing from the station (that is, the wireless client) to managed access points and
the downstream traffic flowing from managed access points to the station. These settings
are applied only to managed access points that are capable of supporting these settings.
Disabling WMM deactivates QoS control of station EDCA parameters for upstream traffic
flowing from the client station to the access point. (You can change the settings for the
station EDCA parameters, but these settings do not take effect until you enable WMM.)
However, when WMM is disabled, you can still set some parameters for downstream
traffic flowing from the access point to the client station (AP EDCA parameters), and
these settings do take affect even when WMM is disabled.
