ᐅ Installing Network Cables

Hello,

we are currently building an urban villa with a separate apartment, which my mother will move into. Since we don’t need a landline phone, we want to share an internet connection.

I have little to no knowledge about this matter.

However, I have already heard from someone that I should connect the main router in our house to the telecom connection, then run an Ethernet cable to the separate apartment. This way, the apartment would have its own Wi-Fi, and we would need a DECT phone connected to the main router in our house, if I understood correctly…

Additionally, I want to run an Ethernet cable to the TV to connect it, and I would like a central Wi-Fi setup in the house (we are building with an open gallery). Therefore, I think it will be enough to have a Wi-Fi repeater connected to the Fritzbox via Ethernet cable. Since this will be in the utility room, it probably won’t cover every corner of the house.

Can someone help me with the best way to set this up and what equipment I will need?

I already have Cat 7 cable, which is supposed to be more future-proof ‍♂. It is also clear that I will first install flush-mounted sockets with conduits wherever needed… and then

Since these are two separate living units, the setup should ensure that both have independent networks. Even among family members, it’s not always desirable to have access to the other’s network devices, and this becomes even more important if you plan to rent out one unit. However, this doesn’t prevent you from connecting everything together for now.

Here’s how I would approach it:

Main house:
Install at least one double LAN outlet in every main room. You might also need multiple connections, for example near the TV.
Don’t forget hobby rooms and similar spaces.
At least one LAN connection per floor should be installed on or near the ceiling to support a Wi-Fi access point. If you use a Power over Ethernet (PoE) access point, you won’t need a power outlet nearby.
All network cables typically end in the utility or service room, where you set up a network cabinet housing all equipment. The network cables terminate on a patch panel, which is essentially a network outlet but with many more ports.
To supply the network cables, you need a switch connected to your router.
The choice of router depends on your internet connection type — DSL, cable, or fiber optic.

Separate apartment:
Run one network cable from the main network cabinet to the separate apartment. There, create a small sub-distribution system, for example, network cables to the TV and other locations where LAN is needed. Currently, you could operate a Fritzbox in client mode there, providing Wi-Fi, telephony connections, and three free LAN ports. Alternatively, you could use individual devices. If you want to separate the networks in the future, a different configuration will allow you to isolate them.

I hope you don’t mind me suggesting this, but it would be a good idea to find someone locally who can support you on-site. Basically, it’s not rocket science, but especially when it comes to the details, some expertise is helpful.

Hello [USER=46393]@Stadtvilla19,

hanse987 has already explained it very well. I had replied to you privately (due to the links).
I’m bringing this back into the public forum since these topics have come up more often lately.
Your plan is a simple outlet behind the TV, a simple outlet on the upper floor for an access point, and a network cable running to the granny flat, where there will be a separate Fritzbox.
In general, you should always use a patch panel. With just three cables, you could also choose the (less neat) option of simply mounting a keystone module onto the installed cables, then use patch cables to connect to the Fritzbox.
Then plug the telephone cable into your Fritzbox and run it all the way to the granny flat.
I fully agree with [USER=24727]@hanse987 that you should install more connections and always use a double outlet...
You can easily extend your telephone line by 4 meters (13 feet).
If you install your Fritzbox in the utility room, you will mostly only be able to use the 2.4 GHz network and not the faster 5 GHz band.
Overall, you are cobbling together a network in a new build. As hanse987 recommended, you should find someone who really knows the subject.
Main rooms should have double outlets, ceiling outlets for access points in the most frequently used areas...
The entire distribution should be centralized in a small network cabinet with a patch panel and switch.
Do you really want to limit all options just to save 500€? Opening walls later is expensive...

Of course, everyone has a different opinion on this, but for my part, I don’t really need it. I’m not a fanatic about it; as long as I have good Wi-Fi reception in every room and the smart TV works via cable, that will be enough for me for the next 30 years.

If I have an access point on the upper floor, would I then have 5 GHz coverage throughout the entire house?

But I’m starting to understand how to connect everything to reach the goal… From the router to the switch, which is connected to the patch panel, and from there all the cables go out, whatever their number or destination…

Once you know what you need, it’s really not that complicated.

Thank you

With your statement about 5GHz Wi-Fi, it becomes clear that you don’t have enough knowledge. The 5GHz band has a shorter range and is quickly blocked or significantly weakened by obstacles. If, as you say, you want good Wi-Fi coverage throughout the entire house, you need to plan enough access points (APs) in the right locations.

If you stick with 3 cables, you don’t need a separate switch. The router alone is sufficient. The simplest solution would be to install keystone modules on your 3 installed cables and then connect them to the router with patch cords.

In the basement, you will mostly be on the 2.4GHz band since the router is installed in the utility room. On the upper floor, the 5GHz reception depends on the router’s position.

If that works for you, it’s a simple and cost-effective solution. However, it is far from optimal.

I have no idea either. But I’ve already realized that it’s not as complicated as I thought.

Now I’m just curious if there are good solutions for cable management here. Should the cables come up from the floor and be routed to the router using a surface-mounted cable duct? Or what options are there if you want the cables to come out of the wall flush-mounted, so it looks neat?

Are you having your house built?

Then you tell your electrician where you want the network cabinet (even if you don’t actually install one there, but only a Fritzbox) and where the network outlets should be. The electrician will take care of it. One end of the cable will be the outlet in the wall, and the other end will hang down from the ceiling at the location you requested.

The latest – and expensive – Fritzboxes can set up a guest LAN on LAN port 4. You can connect that port to the network outlet in your granny flat or secondary unit. This way, the secondary unit is isolated on the Fritzbox’s guest LAN. You can then connect another Fritzbox there, which provides normal internet access via LAN and Wi-Fi. This setup keeps the secondary unit separated from your main home network.
