Whatever the amount of Network sockets you think you need add a couple on! I thought 4 would be enough, 2 years later we need a minimum of 6 in the living room. CT100 for the TV’s, install a decent splitter/amp so it can distrubute the signal from the main TV or aerial to all other TV’s, handy for parties and things.
Trail Rat, streaming HD movies to Apple TV is fine, but see what happens when you have 2 people streaming movies another streaming music and another surfing the internet. You’ll find you’ve maxed the Wi-Fi and everything starts to fall over. Also no setting up required for wired, quicker and less faff’age.
You need to work out the bandwidth for each device, so you can work out how many cables you really need. I doubt all 12 network cables are going to running at max all the time, you may get a way with half as many and add a switch in the living room.
Markie,
For speaker cables, my dad had what looked like drain pipes installed in the walls, so he could upgrade the speaker cables in the walls by pulling the new cable through, it was very easy.
