I have the problem on one of my machines that it is not possible to select WPA2-PSK [AES] network. It is missing in the network encryption dropdown (please see a picture below from my computer where it shows (and works), on the other computer the currently selected alternative AES does not show)
Any pointers on how to get it added are much appreciated.

Simply put, you need either a newer network card, or a newer driver.
Forget the brand of device you bought and just take a look in device manager for the actual chipset maker - Atheros, Realtek, Intel etc.
Go to the site and see if there is an updated driver you can use.
If an update does not work, it means that WPA2-PSK is simply not compatible with your current card and you will have to buy another.
