One of our instructors at school has a Macbook Air and was planning to access the internet wirelessly in her classroom but the college wireless connection is not strong enough in her area. She has access to a ethernet data port in the room but her Macbook doesn't have an ethernet port. Is there something like an ethernet-to-usb adapter that she could use to connect an ethernet cable from the wall to her laptop? 
Or is there something else she could use to easily hook up to the internet in her classroom with her Macbook? Thanks.
