Only tested in a synthetic environment since none of my > commercial APs seem to support anything besides TKIP/CCMP. > I've tested it against a Netgear Nighthawk X10 with the following combinations: WPA2 Personal (without SHA256) - CCMP-128 (AES) + GCMP - CCMP-256 only - GCMP-256 only All of the above are working like a charm. I haven't tried any Enterprise combinations due to some unrelated hiccups on my test rig. Huge thanks for the amazing help Emil
