iPad ethernet connection? I'm looking for a hardware solution for a work trip I'm taking soon. The options at the moment seem to be a new Chromebook, or an iPad (which I already have) with bluetooth keyboard. I need a full-sized keyboard (I'll be doing a lot of writing, and Google Drive is an acceptable editor), and a web browser. However, I am not confident that wireless internet in the venue will be as reliable as the wired (ethernet) connection. I would need a USB dongle for the Chromebook; is there a solution to provide a comparable ethernet connection to the iPad? (Comments on this answer suggest no, but I'm curious if anything has changed, or if there's a more general solution than that question asked for.)
You could always buy a small router. An Airport Express (or any other cheaper alternative) would do, if you have access to a power socket. 

There might be devices that don't need to be plugged in, but I don't know any good ones to recommend.
