Anyone tried a MIMO capable WLAN card in monowall ?
A found one thread only with assumptions that MIMO won't work, but will 
it work till 54mbit for now, so we can maybe use it in the future ??

I already have a WLAN USB stick in the box, which is installed with the 
captive portal... can I install a second WIFI card (for instance a MIMO 
capable one), and add WPA/WPA2 onto it (without the captive portal ?) - 
or is this wireless part only one-time usable ?
