ᐅ Ethernet wiring was forgotten – wiring?

Hello everyone,

we are about to buy a house from a developer. Unfortunately, they forgot or decided not to install star-topology Ethernet cabling.

I’m not yet sure if I want or can completely do without it.

So here is my idea for the wiring, and I would appreciate your constructive feedback:

Sketch of a multi-story home network distribution with switch, router, and Wi-Fi


There is an empty conduit from the basement to the upper floor (originally intended for photovoltaic system preparation) that I would like to use to pull a cable (possibly duplex) to the upper floor and distribute it there with a switch. I want to pull only one cable to keep space available in the conduit for future use.

From the basement to the lower ground floor, a new hole would need to be drilled and a cable pulled up to distribute there by switch as well.

Am I missing something in my wiring plan? Cascading switches should actually allow this, right?

Do you see any major problems or performance limitations?

Thanks for your help.

That's right, my mistake, at 1000 Mbit all 8 wires are actually used.

Nothing beats Ubiquiti UniFi when it comes to Wi-Fi performance 🙂

Not in real life.

Well, if fast-paced online games are played, the kids won’t be happy about an additional 5-10 milliseconds (ms),

Normal switches forward data with a maximum delay in the double-digit microsecond range. Ping times, on the other hand, are measured in milliseconds (ms).

To reach 5-10 ms delay, you’d have to cascade a large number of switches.

How much money can or do you want to invest?
If it’s about space, fiber optic could be an option. Otherwise, Cat7 duplex cable (do not cascade).
I would also recommend Ubiquiti Unifi. It’s best to get the switches as well.
For speed, 10Gb switches are possible but that might be overkill.
For example:
3 x US-8-60W or US-8 if you don’t need PoE on some floors
1 x Cloud Key
Access points depending on your requirements and conditions.
As a router, a USG

This way, you would have a complete system that can be managed centrally and easily. VLANs and other configurations would also be straightforward.
If your demands are not high, unmanaged switches (20-40€ per piece) are sufficient. Naturally, you would need additional equipment for the Wi-Fi.

You poor thing, nowadays that’s almost like running a toilet pipe across the yard :-(

I would say the temporary solution is hardly any worse than a planned one. I don’t see any mistakes.

There are TAE sockets in every room (sometimes even several) with regular telephone cables.

So? – how different are their lengths, can you also add two fours and get eight?

The cables are located in two corners, so it will be difficult... and then there’s the shielding issue. I think that if the phone cables are not disconnected, which I assume, I will go ahead with my temporary solution (have it done). I’m a bit nervous about drilling from the basement to the lower ground floor. There is underfloor heating there.
