After being unable to use the network at Mirjams' parents house because WPA is the default with their experiabox, I decided to upgrade my laptop and my home wireless network to WPA. I searched for a WPA supporting network card for my laptop. Based on the talk at the last sane conference on the madwifi driver project I chose a senao card with an atheros chipset. With a bit of fiddling I got it all working and now I have a secure network again at home.
