Has anyone seen this? On Windows XP PCs, it seems as if a WLAN is set with WPA2-AES/CCMP, it is identified as TkIP instead. I have been told by Spanish Post. They complain about AP5131s not actually using AES, while I suspect it's (again) a MS bug. Problem is that very Intel's wifi utility also reports TkIP. Note that APs only use AES: WPA2-CCMP Mixed Mode is not selected.
