That one is a version 3 (at least that is what one of the Amazon buyers received according to the amazon posts) - I did my best googling the heck out of the list but no luck finding one that would flash via web interface.
Seems like buying one that has already been flashed from ambient weather is an option but that starts to add up when you figure in the station cost - wish I could find a 25 dollar router - I will keep looking with my fingers crossed.
