I also can't answer any questions regarding compatibility. <BR />I only found this: <A href="https://content.cisco.com/chapter.sjs?uri=%2Fsearchable%2Fchapter%2Fcontent%2Fdam%2Fen%2Fus%2Ftd%2Fdocs%2Fwireless%2Fcontroller%2Frelease%2Fnotes%2Fcrn83mr1.html.xml&amp;platform=Cisco%20Wireless%20LAN%20Controller%20Software" target="_blank">https://content.cisco.com/chapter.sjs?uri=%2Fsearchable%2Fchapter%2Fcontent%2Fdam%2Fen%2Fus%2Ftd%2Fdocs%2Fwireless%2Fcontroller%2Frelease%2Fnotes%2Fcrn83mr1.html.xml&amp;platform=Cisco%20Wireless%20LAN%20Controller%20Software</A><BR />As far as I know, CCMP-256 and GCMP-256 are only supported on 802.11ac adapters. Once it's enabled, older adapters can't anymore connect. <BR />Some more info: <A href="https://community.spiceworks.com/topic/2118884-aes-vs-aes-ccmp-vs-aes-gcmp-on-enterprise-wifi" target="_blank">https://community.spiceworks.com/topic/2118884-aes-vs-aes-ccmp-vs-aes-gcmp-on-enterprise-wifi</A> Tue, 02 Apr 2019 09:28:51 GMT https://community.cisco.com/t5/wireless/ssid-wpa-parameters-ccmp256/m-p/3830502#M21769 patoberli 2019-04-02T09:28:51Z
