Well, we have 5 computers networked together in my houseit goes like this:
Hub2--Net PC--Sisters PC
/
Hub1--Dads Pc
|
My PC -Server
All the cables are hidden, there are two cables running from hub 1 to my pc under the floor, one atatches to my ethernet card, the other goes throu the wall to the server. My dads pc is contected by a short wire since he is next to the hub. Hub2 is connected to hub 1 via a wire through the ceiling. then the net pc plugs into hub2(its right next to it) and another cable comes through the wall to my sisters pc.
As you can have guessed the floorboards had to come up, and so did the carpets. We thread the wire through with a fishing rod and then we used those telephone cable securing things to hide the cables behind door frames etc so they cant be seen. We did this this time last year and it took almost a week to get it done correctly ( not helped by the breaking of a cable resulting in the floor coming up again).
