Please, could you explain me how to set WMM QoS form my WLAN connection. Is it possible to do it using any public API. I am using ESeries (E60 and E61) which supports Wi-Fi Multimedia (WMM) as well as WMM power Save (U-APSD) QoS. Also, I can enable/disable WMM power Save (U-APSD) option through WLAN settings on device, but I do not know how to make it for WMM QoS.
