No Internet at RJ45 Wall Sockets After Fiber-Optic Installation: How to Connect Attic Cables

Hello. Yesterday I had a technician to install fiber-optic internet. The internet via wifi works, the cable from the router also works, the problem arises when I want to use the rj45 cable sockets in the wall, because the internet does not work I have 2 sockets in the wall in the house (2 different rooms), in the attic I found the other end of the cables from the sockets in the wall, the cable itself without a plug - admittedly I have just moved into a new house and have not seen them before. I am green in these matters, please explain to me how to make the internet in the sockets, the problem is that the router is in the living room downstairs, and the other ends of the cables from the sockets are in the attic and I have no idea how to connect it :(

The photo shows the ethernet cables that are in the attic.

The router and the optical fiber would also have to be in the attic. Now you won't do anything.

What can you do now? I guess the team that built this house must have known about it, and the fiber optic cable is not long enough, on the other hand, I also do not want to hammer in the wall to let the cables from the attic down: /

Before connecting the router, the installation was ready - the cables were sticking out of the walls and so it was from the building shell.

One must connect to the other. Those cables that stick out in the attic have to be tucked into the router so that there is communication at the other ends - logical. Either router for cables or cables for router.

If you don't want to forge, install some AP in the attic (with at least 2 LAN sockets) in Client mode, assuming there is WiFi coverage there.

In that case, the specialist who installed it had to be drunk: /

And if I connect it to the ap, the connection will not be as stable as during the direct one?

Every cable is a cable ;)

There are many variables with WiFi - the distance, type and thickness of the walls, the angle at which the signal passes through the walls ...

And in this room with the router, you don't have a power outlet?
The operator's router could be connected to it, and a switch in the attic.

Yes, in this room I have a wall socket and a router next to it.

You can also connect something via PLC, e.g. a switch in the attic and these sockets to the switch.

Sketch a diagram of cables around the apartment, because no one knows how and where you have it going.

then check if this cable "flies" to the attic, if so, connect the router to this socket, and install a switch in the attic and plug in all cables there, the one coming from the router and those going to other rooms

And the optical fiber goes into what? Directly to the router, or maybe to a device that is connected to the router via WAN?

The optical fiber is plugged straight into the router, I am not able to do that as far as the sketch is concerned. So in these cables in the attic I have to put on 2 ends, connect the router to the wall socket at the bottom with a rj45 cable, connect 2 cables to the switch in the attic and there will be internet in the second socket?
Maybe by the way I will ask what switch do you recommend? I can see that there is a wide offer on the Internet.

In total, now I am not sure whether it is directly to the router - I am posting a photo of what it looks like.

It looks like directly to the router ...
Well, it probably remains to buy a switch to the attic ... And what - I think, any one, equipped with Gigabit ethernet connectors (a bit more expensive).

Could there be something like this?

Come on. But if you have 2 cables in your attic, no switch is needed. Just connect the cables behind you and that's it. There are special "barrels" for this.

Meaning ? It seems to me that there are other ends of the cables from the sockets in the walls (2 sockets), how would I connect them, it will be internet in the sockets ??

How-how? Just like that. The switch is used to split the connection. In the attic, you don't want to separate anything and you don't want to connect anything. As I understood there will be no computer or printer or anything in the attic. So if you have a Router (and the router has a switch, these are 4 sockets) then you just have to "extend" the cables further, to the second socket.

So I would have to pull cables from the attic two floors below to connect them to the router and then there will be internet in the sockets?

I have already written to connect via PLC or some router in client mode. You don't have to pull the cables down.

Draw it, show a diagram. Because I can see you struggle with it. And even more so we.

Okay, I'm gonna come home tonight and I will.

Stachurson110, I'm worried about you.
I don't think you've come home yet, and it's been over 6 years!
