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

Oh dear. Don’t you have an electrician?

The simplest and most future-proof solution: Have the electrician install a cable with a double socket in every room, including the granny flat. The electrician will then neatly organize this cable mess inside a distribution board. From there, you can run further cabling toward the router. It’s not exactly neat, but since all this goes into the utility room, it’s less of an issue.

Background: You might want to stream here and there when you’re older. Streaming won’t get any less demanding, so relying solely on Wi-Fi won’t be enjoyable in the long run. Anything stable should be connected by cable to a LAN outlet. Your kids will hate having to share the Wi-Fi with you.

Our neighbor recently vented to me about exactly this. The old penny-pincher equipped his house with excellent Wi-Fi. But now everyone is online every evening. The older son plays games late into the night with his friends. The other one is streaming Vikings. His partner watches her yoga videos on YouTube. He wants to calmly book a vacation online, which barely works because the connection is saturated. I had to laugh because I predicted this. It’s not a life-or-death situation, but it is very annoying. You don’t want these problems in an expensive custom-built home.

In your case: you will move into the granny flat when you’re older. Your daughter will move into the house with her entire family. She, being a digital native, sees streaming and the like as her inherent right. So she and her family will heavily use the internet. Your Wi-Fi channel (no matter how capable) will simply collapse. You won’t even be able to watch public broadcasts like ARD or ZDF (which by then will only be streaming).

No, we didn’t have the house built, we built it ourselves. We originally planned to have the entire electrical work done by a professional, but unfortunately, the electrician quoted us extremely high prices.

We also had a few minor additional requests, and he wanted to charge an extra 80% for those... That’s why we are handling the roller shutter controls ourselves, planning to use Homematic IP for that, as well as the satellite and network cables. If we had asked our electrician to do all of that as well, we would be looking at an additional five-figure sum. That is not reasonable.

Background: When you’re older, you might want to stream here and there. Streaming won’t get any less data-heavy over time, so relying on Wi-Fi won’t make you happy in the long run. Anything that’s fixed should be connected via cable to a LAN outlet. Your kids will hate sharing Wi-Fi with you.
Our neighbor recently vented to me about exactly this. The frugal homeowner equipped the house with the best Wi-Fi. But now everyone is online in the evenings. The son plays video games with friends late into the night. Another son is streaming Vikings. His partner watches yoga videos on YouTube. And he just wants to calmly book a vacation online, which hardly works because the connection is overloaded. I had to laugh — I predicted this for him. This situation isn’t life-changing, but definitely annoying. You don’t want such problems in an expensive home.
In your case: You’ll move to the granny flat when you get older. Your daughter will move into the main house with all her family. She—being a digital native—considers streaming and such a birthright. So she and her family will heavily use the connections. Your Wi-Fi channel (no matter how capable it is) will simply collapse. You won’t even be able to watch public broadcasters like ARD/ZDF anymore (they’ll be streaming exclusively by then anyway).


You might be right—or maybe not… Everyone manages with what they have. If your neighbor lived in a four-room apartment, he’d probably face the same problems. Of course, you could say that when you build your own house, you have control over things.

You’re thinking far ahead—by the time I’m old sitting in the granny flat watching ARD with my wife, at least 35 to 40 years will have passed… Technology will have advanced rapidly by then. Wired connections are practically old-fashioned; you can even charge your electric car wirelessly. Maybe in 15 years there will be Wi-Fi far better than any cable, or Cat7 cables will be a thing of the past. These are all unknowns…

We haven’t budgeted much for that, and since we’ve already had unexpected costs here and there, our reserves are tight, so even an extra $2000 hurts…

Besides, the kids should go outside and play, not just stare at screens.

I think with at least one LAN outlet by the TV, one upstairs, and maybe some leftover cables in the children’s rooms, we’re better equipped than 80% of the homes built in the last five years, from what I’ve seen…

He now wants to quietly book the vacation online, which is hardly possible because the internet connection is fully used. I had to laugh when I predicted this for him. Of course, this situation is not critical, but definitely very annoying. In a costly custom-built home, you don’t want such problems.

In your case: you move into your granny flat as you get older. Your daughter moves into the main house with her whole family. She – as part of the digital native generation – views streaming and similar activities as a basic right. So she and her family heavily consume the bandwidth...

With a LAN socket like that, you are quite inflexible. On our ground floor, everything is fixed in place; besides, I already have a technology conduit within the wall, so we won’t be moving furniture there—that will always stay the same. But in the kids’ room, for example, there are three different ways to set it up. If the LAN socket is on the opposite side of the room from the TV, then the cable mess starts all over again...

I actually think that young people are becoming more flexible. Who even uses a PC much anymore? Even a TV is starting to seem old-fashioned. The trend is clearly smartphones, tablets, and laptops so you can stream or play flexibly from anywhere. LAN sockets don’t really help much with that, except that you can strengthen the Wi-Fi with an access point—but am I misunderstanding something?

Maybe in 15 years there will be Wi-Fi much better than any cable, or Cat7 cables will be considered old-fashioned. These are all things nobody can predict...


That’s why many now install cable ducts inside walls, so they can upgrade later without having to break through walls. Wired connections will remain important as soon as high bandwidth is needed.

And kids should go outside to play, not just sit in front of the TV.

I think having one LAN outlet by the TV and one upstairs, or maybe another in the kids’ rooms if extra cable is left, already puts us ahead of 80% of the houses built in the last 5 years, from what I’ve seen...

Yes, I realize even small costs can add up and hurt eventually.

You don’t have kids yet, or just small ones, right? Because they will be gaming, watching TV, etc., whether you like it or not.

I also believe that young people are becoming more flexible. Who still really uses a desktop PC extensively? Even TVs are becoming old-fashioned. Smartphones, tablets, and laptops are popular so you can stream or play flexibly from anywhere. LAN outlets don’t help much there, except to boost Wi-Fi with an access point, or am I mistaken?


The outlet doesn’t have to be right next to the device. One double outlet where the TV wall will likely be in the living room is enough. The extra meters are then covered by a suitably long cable. But at least the main user—the TV—is on a different data channel that way.

The same applies to the kids’ rooms. Our outlets are under the window, where the desk will probably go later.
And you wouldn’t believe how much bandwidth a good first-person shooter demands over the console. It’s crazy! And yes, PCs are still popular. Most households have PlayStation and Xbox consoles too. Then there’s the TV, which often doubles as a monitor and has its own streaming apps...
Our kids are still small, but even they are streaming. My husband plays on the PlayStation, I relax in the bathtub while binge-watching Netflix, our son watches Ninjago on his tablet, and the youngest just sleeps (though even she enjoys kid’s songs and dance videos on YouTube with me). The son and I are connected via Wi-Fi, and you can really see the load on the network.

Yes, we already have two children, one who is 9 years old and the other just 3 months.

We follow a rather traditional upbringing, and I insist on that. Our 9-year-old currently has no special privileges except watching TV for 30 minutes in the evening. On weekends, if we want to sleep in, he can use his mom’s phone to watch a few YouTube videos.

We believe that children up to the age of 10 should first learn to entertain themselves. What comes later as they grow older cannot and should not be prevented. I just hope my children turn out like me and prefer playing outside with friends rather than spending the whole afternoon in front of the TV... I always found that boring back then.

We’re not extreme enough to watch Netflix in the bathtub. A bathtub is for relaxing, and most of the time I take a bath with my wife, so we don’t need anything like that.

I don’t have a gaming console either; at 29, I’m still old-fashioned. We are busy enough with work, housework, meeting friends, building a house (later garden maintenance, tidying up), and hobbies.

I don’t think we will ever have a shortage of things to do.

I’m also still willing to press a light switch—movement is healthy. I don’t want to come home from work (where I already sit a lot), sit on the sofa, turn on the TV, and say “Alexa, do this,” “Alexa, do that.” I’m happy to get up and dim the lights or turn on the radio.

BUT that’s actually a different topic that could be discussed for days, with everyone having their own opinion.
