ᐅ LAN and Wi-Fi – Separate Devices per Floor?

Hello,
I am a beginner when it comes to the internet and I want to set up a Wi-Fi router in the basement of a new house. Then, on the ground floor, first floor, and attic, I want to connect a device to a LAN outlet that receives the signal from the LAN cable, and then both broadcasts Wi-Fi and provides a LAN port so that it is possible to connect directly via LAN cable without disabling the Wi-Fi. Ideally, the device would be powered by a plug-in power adapter and, if possible, be wall-mounted. Does something like this exist? If yes, which devices would you recommend? Or is having a LAN port on the device unnecessary because the Wi-Fi signal in the room is likely to be very good?

Thanks in advance for your answers.
Best regards from Tom

You don’t understand. I already mentioned that you could connect a switch to the socket (with some power loss).
A double socket is not an option.
A modern house already has more connections in the office and living room than you have in total. That should answer your question.
Wi-Fi is only for mobile devices. Everything else should be connected via LAN.

We trusted the electrician for the electrical installation,

For the electrical installation, yes, but when it comes to network planning, this is usually not a good idea! Was there at least a test report for the installed cables? For me, this would be the only reason to have everything done by the electrician.

Since it sounds like you’re not very familiar with the topic, I would recommend using the Fritzbox. Where will the router be located? The area around the router position needs to have good Wi-Fi coverage. This will determine the choice of model. You don’t need to install an access point in every room. Less is often more! You’ll need to test what you actually require. If multiple LAN ports are needed, either use a switch with an AVM repeater (but set to access point mode), or you could use a Fritzbox from the 4000 series and operate it as an IP client.

I don’t think the situation is ideal, but believe me, there are still new buildings without any network cabling where you can only use a wireless setup, which can be a disaster.

I’m joining in here— we have about 14 LAN ports (CAT 6A, single cable) distributed throughout the house, all converging centrally in a network cabinet in the basement. The offer included a 19" rack with 12 rack units (12U), a 16-port network switch, and an 8-outlet power strip. The 16 ports seem a bit tight given we already have 14 LAN ports. Assuming we decide to add 3 more LAN ports during the relevant construction phase, what would be the next larger switch size we would need? Are duplex cables more practical than single cables?

Yes, definitely.
Install duplex outlets and double sockets right away. For the TV and office, it's better to have extra.
Use a 24-port or 42-port switch from the start. Also, get a larger patch panel.

For 14 connections, I wouldn’t choose a 16-port switch but go straight for a 24-port switch. I also wouldn’t get the device from the electrician but organize it myself afterward. Passive technology handled by the electrician, active technology done by yourself.

Duplex cables are simply two individual network cables glued together. Which type to use should be decided by the electrician. Every network socket should always be installed as a double socket, and in places where more devices might be needed (office, TV, etc.), install more than one double socket. Then there’s the issue of access points for Wi-Fi. Personally, I would only place these on the ceiling and power them via PoE. Of course, a cable must run to them along with a small junction box to hide everything behind the access point. If the ceiling is not an option for some reason, place them high on the wall. The position of access points depends on the floor plan and user behavior. Without that information, all you can say is that usually at least one access point is installed per floor. Most network planning only considers the living area, but the rest should not be forgotten. Outdoor access points, network in the garage (for electric vehicle charger), network for inverters, network for the intercom, cameras, and so on. This leads us back to PoE, and if you have many devices, you use a PoE switch. So you can see that the choice of switch depends on the components you have or need.

If you use cheap access points, you'll get an outdated standard. Therefore, use a Fritz!Box and FritzRepeater 2400. Set these up as access points. You’ll also have a LAN port available on the access point.
ok.
Do you then consider the FritzRepeater 2400 to support a reasonably current standard?
And with the FritzRepeater, is it possible to skip PoE (Power over Ethernet) because... (?)...
