Communication cabinet connection

Hello,
We have just moved into an apartment equipped with fiber optic and a communication box.
An Orange technician came to set up our Livebox 5, which works perfectly via Wi-Fi.
However, it's impossible to get the sockets in each room to work.
I don't know anything about this system, and despite spending the evening watching tutorials and forums, nothing works.
Here’s a photo of the installation. Can you tell if there is a missing connection at a glance?

I should note that the box is connected under the electrical panel because it is impossible to fit it into the installation or run a cable from the box to the installation (it is closed by a door).
The box itself is connected only via the fiber optic cable to a fiber box installed on the wall under the electrical panel, which is in turn connected to the fiber box of the installation.
Thank you in advance for your help!

Hello,
if you had explored this wiring forum a bit more, you would have found plenty of resources for a solution to your rather mundane problem.
First, you need to remove the 5 cords between the patch panel located to the left of your fiber PTO and the TN111 telephone distributor, which has become unnecessary.
Then, connect real RJ45 Ethernet cords between the Ethernet ports of your box and the patch panel for the wall sockets you wish to power.
Hello!
I haven't seen anywhere that the distributor is no longer to be used in my case, there are so many configurations :o
My problem is also there, is there a way to bypass a direct connection between the box and the cabinet? The panel being in the middle of the living room, leaving the door open is not a solution for us...

In the middle of the living room?
In principle, it should be in a closet, an entryway, or a garage, not in the middle of a living space.
In any case, whether it's closed or not, you should have all the electrical distribution above with the circuit breakers and all the mess.
Is it a studio?
You could put a small switch in the panel, but then you need to move the box close to a wall outlet and install a sufficiently long fiber jumper between this panel (the PTO) and the box.
Who are you telling this to..! Yet the whole painting is indeed on a wall in the living room, hidden behind the very aesthetic white metal door!
You mean that by connecting the box to one of the Ethernet sockets in the apartment, and equipping a switch in the cabinet, we could send the network from this switch (first connected to the patch panel on the socket receiving internet from the box) to the other rooms by reconnecting the switch to the other sockets of the patch panel?

Hello... how many RJ45 ports are there in the living room?
If there are two, we can consider installing an ONT (to be purchased if it doesn't already exist) in the communication cabinet, using one of the two ports to carry the signal from the ONT to the Livebox5 port and the second for an output from the LB5 to the mini-switch also installed in the communication cabinet.
Hello,
Regarding the location of the Box, I also have one of those wonderful cabinets in a living room with an integrated kitchen, but the cables need to go somewhere: I made sure that the technician routed the fiber from inside the cabinet through the telephone and antenna cable pathways (there was no RJ) through the walls, so that the ONT and the Box are in the room of my choice and the cabinet is closed.
Of course, this does not solve the management problem if the cabinet is not large enough to accommodate a switch and assumes that the RJ45 sockets in the rooms are operational.
In fact,
a box like that must be about 250 mm wide.
a LB5 is 230x185
By removing the unnecessary TN111 and the DTI which has also become unnecessary, you can let the DTI hang at the back behind the box marked A43, you should be able to fit your box into this cabinet and close the lid, all that’s left is to sort out the power cable, is there a socket at the panel?
And there you go ....
But misery, how annoying the line spacing is!!
Yes, of course, we can always fit the Box and the ONT by removing the DTI and provided that we can plug a power supply into the electrical outlets of the circuit breaker that conveniently flush with the cupboard door.
But what also dictates that we run RJ45 to all the rooms and equip them with sockets: you can imagine that I managed differently, connecting devices via Ethernet in the room where the Box is, using Wi-Fi or powerline Ethernet (TV) in the others.
