We just bought a new house.  Keen to have comments on my plans for data networking.

The house is four years old, about 200m2 two levels: with living, office and master bed on upper level; kid/guest bedrooms and garage on lower.  The upper floor is timber.

Phone outlets in master bed, office and kitchen. Satellite (no UHF coverage) via coax to all bedrooms.  4 years old and they didn't fit any network cables :facepalm:.

Our collective current and future uses of the network include: media streaming, web surfing, gaming downstairs only (including multi-player online gaming).  We will gradually build a Sonos network.

I can get Cat 6 cables run down the internal walls on the upper levels, by a guy I have used before who does a good job.  It will be slow work, so my thinking is run the fewest number of cables and install switches. 

A switch costs about $40, as does an hour of labour.  I also think it will be easier to have clusters of devices connect into a switch than have say 6 cables into a wall plate.  But hey I'm new at this so my assumptions maybe wrong. I'm thinking the following: -

Office (middle of upper level): -
- Modem into existing phone outlet
- 2 x RJ45 wallplate
A) Cat 6 to lounge
B) Cat 6 to master bed
- Gigabit Wifi router (4 port)
1) NAS
2) Gigabit switch (5 port)
   i) Sonos unit
   ii) Printer/Scanner
   iii) Dyna dock
   iv) Spare
   v) router
3) To wall plate A
4) To wall plate B

Lounge: -
- 1 x RJ45 wall plate
- 8 port gigabit switch
1) Samsung 'Smart' BD player
2) DVB-S reciever
4) Onkyo 2 zone network receiver
5) Future Smart TV
6) Future HTPC
7) Spare
8) To wall plate

Bedroom: -
1 x RJ45 wall plate
- 5 Port gigabit switch
1) Sonos Unit
2) BD Player
3) Smart TV
4) DVB-S decoder
5) Spare
6) To wall plate

The bottom level will have to make do with WiFi.  I think the signal will be OK through the floor.  but I can install a wi-fi repeater if I have too.
