ive got a completely wired home network
basic 2x Cat6 cables to each bedroom, 1 for computer/laptop, and 1 for emerging requirement of a network cable for things like TV, Blu-Ray, TiVo etc..any more than 2 seems rediculas so may as well put a switch in lol if you start needing 3 then chances are you will need more.
Then 1 for the living room, connected to a netgear prosafe switch, for TiVo, Print Server, Computer, and Xbox 360.
All cables go back to under stair cuboard into a Cat 6 Patch Panel.. then on into a 24 port Netgear Prosafe POE Smart switch... bit overkill on that switch because ive also got redundant network cables in place for outside IP CCTV for future use, and running an expandable NAS and things in there so I have a central file store for everything as well as a netgear prosafe wireless access point.
Superhub is running in modem mode behind a Netgear Prosafe VPN Firewall Router.
All 1000 Tbase Gigabit ethernet
So im all future proofed.
But ive used the under stairs cuboard as a kind of central location for everything.. all the telephone sockets in the house are wired back to there in a star arrangement, also got the alarm panel in there, CCTV cables etc.
Maybe some of it seems a bit overkill but im self employed in IT and work from home a lot of the time.
