Is what I'm wanting to do possible? I'm going out of town later in the week. I have an airport express, and where I will be staying has broadband, but not a wireless router, only wired ethernet. What I would like to do is take my airport express, just plug in their ethernet cable, and use it for my ipad so i don't need to take my 7lb. work laptop. Is this possible, or would I need my laptop to setup the express? Can I do it from the ipad?
