WiFi can be great for lots of things, but if you’re moving large multimedia files arounda and streaming media through your home network you can easily swamp the bandwidth that’s available and cause yourself no end of problems.

If you’re not going to use WiFi and you still want all your electronics to talk you need to run Category 5 or Category 6 cables between them (they look the same, but CAT 6 cables are rated for higher speeds). This Instructable goes over exactly how to get this done: from planning, to breakout boxes to cleanly running the cables through the walls. If you’re looking for a professional in-home network this is definitely the way to go.
