I've been using Apple's AirPort Express ( http://www.apple.com/airportexpress/ ) with my 770 at hotels this winter. It is not cheap at 129$, but it's easy to bring along as it is not large, "plug and play" easy, and it works great with my 770 (as well as with my PowerBook and my wive's Windows based PC). I did not have to install anything on any of the devices i used it with, worked right out of the box, just connect the ethernet cable.
