Are you suggesting WPA-PSK(AES) doesn't exist in reality but only on
selectable menus?

The links Lem posted actually accepted that AES/CCMP was used with WPA
sometimes but wasn't specific about any (security affecting)
difference between the implementations in wpa and wpa2. From those
links I got the impression that the security algorithm was equivalent
in both implementations.

I do accept the point, though, that even if AES/CCMP is a selected
option on the menu that TKIP might be used without informing the user
if the hardware can't handle the AES.

Hi
WPA-PSK(AES) is a sort of WPA2. Since Wireless is the "Wilde West of
Networking", for variety of reasons some manufacturers at the moment prefer
this term.
From the user perspective if there is a choice between with AES and without
AES, the AES choice is better one, If there is a clear choice of WPA2 then
it should be used.
