Hello,
I just moved into a rental house built in 2009.
It is equipped with an RJ45 socket in the living room, kitchen, office, and one in each of the three bedrooms.
I connected my box (SFR) in the living room upon arrival, no problem, internet active via Wi-Fi and by cable connected to the TV and Philips Hue bridge, for example.
Today I made my connections in the office, RJ45 cable from the wall socket to the computer, no internet available, as if it didn’t recognize the cable. I then connected the box in the office and it works, so the wall socket is fine.
But I want to leave the box in the living room and connect my computer through the wall-mounted RJ45 socket.
I am not familiar with this system at all; I’ve never had RJ45 wall sockets before. I did my research, and I think that my electrical panel is simply not connected to the RJ45 sockets in the house...
Attached are the photos of the panel.
I have the impression that my 6 RJ45 sockets reach the panel but that all the colored wires are connected to nothing...
Is that right according to you? How can I solve the problem to have internet at every wall socket?
Thank you for your help.

Hello,
It seems that the wiring was done for telephony but not for Ethernet.
Your RJ45 sockets in the rooms are probably connected with 2 of the 8 wires that the cable has.
The telephone line arrives at the DTI and the 6 cables must be connected there with 2 of their wires each.
Check how the RJ45 sockets in the rooms are wired.
Then open the DTI to see if the 6 cables are indeed connected there with 2 of their wires each.
To bring everything into compliance for Ethernet, you will need to redo all the wiring
in the rooms, reconnect the 8 wires of each cable to the RJ45 sockets
Next to the DTI, install and wire 6 female RJ45 sockets to create a patch panel to achieve an installation like this
It's very difficult to catch a black cat in a dark room.
Especially when it's not there...

But it will be if the box has to stay in the living room.
However,
since there is only one socket in the living room, a pair of RJ45 splitters will need to be added to have phone and 10/100 ethernet network on 2 pairs (1/2 and 3/6) and ADSL line on another (4/5).
The network with the box will be limited to 100 Mbit/s, but that's not a problem because the LAN will still be gigabit; only the internet access will be limited to 100, which is not a concern for ADSL.
Afterwards,
when fiber arrives, it will either be installed at the communication cabinet (which is the best in my opinion) or where the box is currently in the living room.
Since the two splitters will no longer be needed, the speed can go up to gigabit/s
Splitter model
or here
make sure to take the model with ethernet plus phone, not two ethernet (see diagram).
And you need two, one for the patch panel and one for the wall socket.

Here is the inside of the DTI. Indeed, a white and grey wire from each cable are connected, not the others.
At the DTI, do I just need to install 6 RJ45 sockets that need to be connected to my 6 cables? Nothing else?
So I could use my box in the living room and it will send the network through the 6 cables? No need to leave the box in the DTI? (No space planned!)
Thank you
Yes, absolutely, patch panels at the end of the cables, probably re-cabling the wall sockets in the same way and that should work.
Example of sockets: At the end of the cables of Keystone modules:

And the modules are held in a plastic support fixed to the rail:

or a less bulky metal support: https://www.maison-du-cable.com/Prix/Support-Keystone-pour-rail-DIN--acier-402357.html
In local stores, you might find this type of outlet more easily.
