I'm gonna be moving into a house that was built in the mid- to late-90s and early on what I wanna do is get wired Ethernet installed to the upstairs bedrooms and lounge. What I was thinking of doing was getting a little cabinet built around the Openreach box where I could stick the router on top, wire it to a switch below inside the cabinet, and have that plug in to a bunch of wall sockets via patch cables. Is that a good idea, though? If so what cables are best to use, cat5e or cat6? I've seen elsewhere that sometimes Ethernet over fibre is used but presumably that'd need to have a powered media converter at each end of every connection which sounds like a right ballache.
How tricky is it for a builder to knock holes in walls and do this with a house of this kind of age? Or should a specialist networking company be brought in to do it? I'd like to have the cables run in the walls rather than around skirting board etc. and I'd rather the cables not go outside the house, just seems like they'd have less wear and tear if they're all indoors.
I have wired my 1988-built house with Cat5e with no cable visible internally.
I have two external runs. One from my office to the point where the ONT is mounted and one to the attic. Both are terminated in sockets (krone tool required; it's easy to do. Additional devices are accommodated by unmanaged switches.
Runs from the office to the hall and integral garage were routed under the laminate floor in the hall when the laminate was laid.
The plaster board was fixed by dot and dab, which means that there's a void behind it. The runs in the office go behind the skirting and the plaster board to reach the sockets. The run from the attic to a socket behind the TV in my bedroom also goes behind the plasterboard - I had to drill a hole through the header plank to get into the void.
It's about ten years since I installed the wiring and I've had no problems with it, even outside. Having changed the switches it runs at 2.5Gbps.
There should be no need for a builder to be knocking holes in your walls. A drill will be quite adequate.
