I'm moving into a new apartment that is hooked up with ethernet and I'd like to get a router to use my MacBook Pro wireless. I was looking at the AirPort Express. I wanted to find out if it's possible to use the AirPort express as a router/splitter. For example, how can I set it up so that I can use my MacBook wirelessly yet have my Roku HD and XBox 360 connected by ethernet wire. Is this even possible with the Airport Express or do I need something like the Airport extreme? Also, is it possible to just buy a splitter to connect to the wall's ethernet and still use the Airport express and other gadgets I mentioned? Thanks.
