WPA-PSK possible with prism2 card ?

[jar]

Hello

Is it possible to use old prism2 card with fw:1.5.6 as a WPA-PSK+CCMP or 
WPA-PSK+TKIP hostap&hostapd access point? Is the firmware too old for that?

How about in the managed mode? Is it possible to use this same card as a 
WPA-PSK+CCMP or WPA-PSK+TKIP hostap&wpa_supplicant client?

Does this extra security stuff decrease the mtu of the wlan0 device, or 
can it be 1500 ?

BR, Jar
