Wireless networks may be convenient, but wired networks beat Wi-Fi in every other way. Wired networks are faster, they're always reliable, and they're secure. Unless you're sitting on the couch with a laptop, or connecting a Wi-Fi-only device, such as an iPad, wired ethernet is the better way to go.
But what should you do about the tangle of wires? Homeowners can run cables inside the walls, potentially increasing the value of their house for tech-savvy buyers. I'm making a few home upgrades and began wiring it up for ethernet even before it had a working bathroom. (I have my priorities.) Here's how you can do the same in your house.
Make a Plan
Before you start laying cable, take time to figure out a few things. Where do you need ethernet jacks? Where will your central networking hardware sit? What are your logistical limitations? (If you aren't sure whether you need ethernet, read our "The Ultimate Guide to Home Networking" for tips on determining the right networking technology for you.)
I wired ethernet to six areas throughout my small house: two in my office, one in the bedroom, two in the living room, and one in the kitchen. Each length of cable goes back to a closet containing the networking hardware, in a "home-run" layout.
Since I was committed to doing this project anyway, I decided to overdo it a little, running multiple cables to nearly every location. As a result, I can configure advanced networks, with the ability to do such things as completely isolate certain devices at the same location from each other, or even to directly connect something to the Internet. I put four ethernet jacks at each location in the office and living room, and single ethernet jacks in the bedroom and the kitchen.
My setup is likely overkill for many people. You might prefer to run just one or two cables to each location. If you have multiple devices--such as a TiVo, a PlayStation 3, and an Xbox 360--you can connect a switch outside your wall to add more ports.
