I use the Airport Express at home and it would be a perfect solution, but for 2 issues.

First, it reuqires a hard wire input, and most of the places I stay have wifi but not an ethernet or other hard wire. I need a repeater that can do both.

Second, the Airport Express is a little heavy to be carrying around for this purpose.

Thanks for your post-that Asus model looks like it would be of little help and I really want to avoid buying a unit, figuring out how to use it only to learn it doesn't do what I need.

Anyone have any other suggestions?
