Just got the revision100 and I'm currently testing it on my WPS Router. Will leave it overnight and I'll report the 'findings'. (seems much faster than 1.3 initially)

EDIT

I have some problems with wash though, doesn't seem to work.
Constantly returns:

"Found packet with bad FCS, skipping..."

and thats it.

EDIT 2:

walsh -i mon0 --ignore-fcs

fixes the above problem

EDIT 3:

For the sake of having 3 EDITs..:
option -d 0 speeds things quite a lot, though it depends if the router actually accepts it and doesn't crash. It is definitely worth trying though.
