Thanks, I am mighty impressed that you were able to find that link on the Toshiba site, even though it's the original driver (I have that one, no WPA).
For what it's worth, this is the link where I saw the reference to Driver Guide:

all the way at the bottom, mike_b_32768 says it's still available here, though that link isn't the way to get there.
