I am having a similar problem on a laptop of mine - I kind of gave up because 
I'm getting a new laptop in a month or so anyway, but I wanted to outline the 
problem I am having.

What I understand is that versions of the prism firmware lower than 0.5.6 iirc 
don't support wpa, where higher versions do, but versions above 0.7.4 are 
unstable.

I have been unable to update the firmware using the hostap tools that were 
designed to do so, as they just don't recognise the card and its parameters, 
even though the card is actually found, and the relevant drivers loaded.

Was support for firmware updates removed in an earlier version of hostap?

Thanks,

Tom
