Do devices with WMM-Admission Control work with legacy devices?
To benefit from WMM-Admission Control functionality, both the AP and client device need to be Wi-Fi CERTIFIED WMM-Admission Control. Any Wi-Fi CERTIFIED client devices in a WMM-Admission Control network that do not support WMM-Admission Control will operate as usual in WMM mode, but won’t use the access categories for which admission control is mandated by the AP.
