With Intel® PRO/Wireless Software and Intel wireless network adapters, WMM* (Wi-Fi Multimedia) is enabled by negotiation with a WMM capable wireless access point. No special configuration in the adapter is necessary for WMM support.
WMM is a Wi-Fi Alliance Quality of Service (QoS) enhancement to allow for priority use of bandwidth by audio, video, and voice applications. WMM support is automatically enabled on the Intel® PRO/Wireless Software. In order to use WMM in your wireless network, this configuration has to be enabled in the Access Point.
In the Advanced Wi-Fi Adapter Settings you can find "Ad hoc QoS mode". An ad hoc Wi-Fi network (also known as a peer-to-peer network) is a temporary network used when an access point (AP) or broadband Wi-Fi router is not available. It allows users to wirelessly connect directly to each other. When WMM is enabled in the Ad hoc QoS mode, the adapter uses WMM to support priority tagging and queuing capabilities for Ad hoc Wi-Fi networks.
