Computer cables and Wi-Fi router

Of course they will... why should a house that is inhabited by two people, in which there is a tablet and a PC and two iPhones, in which the light is operated via light switch, have something like that? Karsten

If that suits you, then of course that is legitimate. As a rule, however, one should not advise someone who is building new to do so. That the electrician does not want to lay a duplex here and then only does so minimally is hardly comprehensible.

Also to you: what should one (not) advise the builder?

I don't understand the whole thing!
Does the house work without it or how or what not, or what is meant?

The recommendation:
There should be a double network socket in every room. The cables end in the technical room or similar on a patch panel. From here, you can then distribute what should be on the respective cables. This does not have to be just computer networking, as such cabling can be used quite universally and can replace others.

All stationary devices (computer, television, Playstation, heating system, kitchen radio) and workplaces (connection at the desk for laptop) should be connected via cable. The WLAN should be reserved for mobile devices (mobile phone, tablet, laptop).

Why?
WLAN is a shared medium. That means all devices share the bandwidth (the speed). This means if two devices use the WLAN at the same time, each only gets half. In principle, you also have to count the neighbors’ WLAN, even if you only receive it very weakly. They interfere with the home WLAN and reduce the bandwidth.
WLAN only reaches the stated speeds under laboratory conditions. In reality, usually only a fraction of the possible bandwidth.
For the same reason, repeaters are a bad idea, as they halve the bandwidth; instead, an access point should be provided if necessary.

A concrete example, which I actually had yesterday:
Mom is watching Netflix and browsing Instagram on her phone at the same time. Dad is on the laptop surfing the internet. Son is watching Netflix and running Skype with his friends. Meanwhile, videos are streaming in via Snapchat. And they all complain that the internet is slow and the Netflix stream is constantly interrupted. A brief analysis showed: 100Mbit internet connection far from being fully utilized. In fact, the WLAN is overloaded. Five other neighbors’ WLANs are also on the same channel. Remedy: connect the TV via cable and everyone is happy.

Furthermore, you can dispense with other cabling: telephone sockets become unnecessary, I can distribute telephone signals over this cabling. Especially since most people use cordless DECT phones anyway. Current telephony runs over VoIP. Even now, I can already connect a phone via VoIP over the network to e.g. a reasonably current Fritzbox.
You could also do without television cabling and instead rely on IP technology. For example Telekom Entertain, Zatoo. Or if available DVB-T. This would also work with satellite. The latter I would currently only recommend to technology-savvy users.
The trend is clearly moving towards streaming and away from classic television and radio. I often hear people say they no longer watch TV because they have Netflix. And when cleaning, Spotify plays cleaning music, and in the bathtub relaxing music.
Ultimately, you can also retrofit sensors for an alarm system more easily via the network.

A house also works without network cabling, of course. Just as it works without television cabling, with only one power outlet per room and one fixed phone in the hallway. But that is not state of the art.

That the electrician here doesn’t want to install duplex and then only does so minimally is hardly understandable.

Installing duplex cable is actually very annoying. Because you have two rigid cables together, you can only lay them on one axis. It then behaves like a flat ribbon cable. Instead, it’s better to pull two single cables into an empty conduit and lay that. But the fact remains: One socket is not enough. Always double sockets.

So, when I hear some of you, I think to myself, if their internet goes down, they call the emergency doctor.... well, to each their own. Karsten

To each their own, but the era of constant connectivity will not slow down, quite the opposite.

Wi-Fi should only be an option in exceptional cases as already mentioned above. In all other cases, cables should be available if possible. This applies even more to a new building.
