Hello, I have RJ45 wall sockets in every room of my house and since my computer is too far from my router, I would like to use the wall sockets to be on Ethernet. However, when I plug in, nothing happens. I don't know if anyone can help me figure out how to do it. Thank you.

    There are way too many unnecessary exchanges in this discussion ;-)

    Let's summarize. With our calm experience, we can assure you that with good wiring of the sockets and cable identification, it works (*). There are dozens of discussions on the forum where we have intervened to address this topic.

    This is a subject you are discovering; it’s simple, but in addition to positioning the colors correctly, there are also little details. The cable may be too stripped, the ground wire may touch other wires, wires may touch each other, a wire cut too long may make a poor contact with the casing, ... You have everything in front of you, we don’t.

    In what you have provided, something is missing. We can see that it should be fine, but the other side is not shown. And there are no photos of the wall socket.

    In this photo on the left, we can wonder if the orange wire will touch the metal frame, and below, what are those wires, orange and green?

    Here’s an example of an open core that we encountered on the forum, where wires cut too long are pinched by the metal casing when it is closed, resulting in a false contact between the wires.

    (*) at 99.99...% because of course, a hole made in a wall with a drill could have damaged a cable, but not all. And we assume that you have tested the port of the used box, the port of the PC, and the Ethernet cables.

      I didn't see this message. When I get home, I'll redo the wiring and let you know if it's still the same.

    Hello.

    You need to find out where these outlets connect, usually near the electrical panel.

    For the installation to work, the outlet you are using must be connected to a switch, and the box must also be connected to that switch.

      I found where the outlets come in, but do I need to buy switches? Because I also have 2 wall outlets side by side near my box which is located in my living room.

        Normally, all RJ45 jacks arrive at the same point. Currently, how are they connected?

        Sorry, I'm not familiar with it, so I'm not sure about my answer; they are all next to the electrical panel. If you want, I can take photos if my answers are unclear.

    Where there is the black ethernet cable, there are 4 other ports (6 in total) and where it says dti test, there is 1 as well

      As is often the case in construction, it's a case of "hodgepodge" work.

      What is the current purpose of the black RJ45 cable loop?

      In fact, you need to locate the RJ45 socket that comes from the wall socket where you want to connect your PC as well as the one that is close to your box. If the work had been done correctly, this should have already been done...

      Once you've located your two sockets, connect your black RJ45 loop between these two sockets.

      Take your time and above all, put labels on everything you identify.

        The black RJ45 cable was used for testing to do what you described, but it never worked at any point. I will try with the second RJ45 socket that is in my living room to see if it works.

    Hello,

    How is the box in the living room connected to the fiber arrival box that you can see in the bottom right of your photo?

    An Ethernet output from the box to a wall socket and a bridge with an Ethernet cable between the patch panel in the living room and the patch panel in the PC room is the logical connection.

    But are the patch panels well labeled to identify the rooms?

    And especially the left patch panel is not in its support; we can see that it should be connected with a brown cable to the DTI.

    However, it is wired on 2 wires. If it’s the same for the others and the wall sockets, the installation is only operational for telephone service. For Ethernet, the wiring of all the sockets needs to be reviewed to connect all 8 wires.

    We should open another patch panel to check and verify the wall sockets as well.

      For your first question, I didn't quite understand what you're asking me exactly, and for the second one, no, they are not identified, so what exactly am I supposed to do here? Am I supposed to remove a wall socket and check if it is wired with 2 or 8 wires?

    Do you have a fiber or ADSL internet subscription? In the latter case, what is in the living room to connect the box?

    If the sockets are not identified, you need to test all combinations one by one. If you have a laptop with an Ethernet port, you could already find the living room sockets by positioning it in the central box and testing them all, with the box connected to the wall sockets.

    But to test the Ethernet network, the wiring of the sockets must be correct.

    A second RJ45 patch socket needs to be taken out of its housing, like the one that is already out, to see if there are any loose wires, in the same way.

    And you should remove a wall socket to see how many wires are connected.

      I have a fiber internet subscription and I already did this test and it wasn't working. I checked what you told me regarding the wall sockets and I don't know if I'm mistaken, but in the photo there are indeed 8 connected wires.

        If you have the opportunity to acquire this item (or an identical function), it will make your search easier.

        You need an RJ45 cable at both ends.

    on the wall outlet, the 8 wires are properly connected, we need to check the patch panels, and ensure that the 2 cablings are done identically

      I just checked and there is one patch panel connection that is not plugged in, and there is also the DTI TEST cable that is not connected. On the RJ45 socket of the patch panel (the one where 8 wires are not connected but only 2), I saw that it was the one from the living room.

      In telephony, only 2 wires are needed, which is why electricians often don't bother wiring the 8.

      So, is this one only for the phone? If so, I can't make it work over the Ethernet network?

      What I meant to say is that in telephony, we only need 2 wires.

      For Gb Ethernet, 8 wires are required. Your telephone cable does indeed have 8 wires that need to be connected.

      Oh okay. But on this photo yesterday, jee pee told me
      "the left patch panel socket is not in its support, we can see that it should be connected with a brown cable to the DTI. But it is wired with 2 wires. If it's the same for the others and the wall sockets, the installation is only operational for telephony. For Ethernet, the wiring of all the sockets needs to be reviewed to connect the 8 wires." The socket he was talking about I managed to read that it was marked "living room".

    Yes, there are 8 wires.

    You should redo the test with the box on the wall outlets and a computer connected to the patch panel, especially if you were able to locate the patch panel outlets in the living room.

      But so for the one in the living room, everything's good? Because there are only 2 (the one you talked to me about yesterday corresponds to the living room).

      It is therefore a wiring defect (when dealing with the patch panel socket / wall socket pair). Both sockets need to be opened to check the connections.

      I just checked and I put the 8 wires instead of 2 in the RJ45 socket (living room) of the patch panel, it still doesn't work.

    For example, one of the two sides of a socket:

    you can see the colors and the numbers. Here it's a type (568) A wiring; the most common is type B.

    And even with this photo, we cannot be sure that the white wire of pin 5 or pin 3 is correct because the correct connection is pin 5, where the white wire is twisted with the blue wire, and pin 3, where the white is twisted with the orange. The colored wires are twisted with a white wire.

      So it's better when the white is bicolor, no doubt about the position.

      Hello again,
      Today I tried to connect my box directly to one of my RJ45 jacks from the patch panel without going through one of the jacks in my living room, but it didn't work.

    Hello, I just have one last question. Let's imagine I have powerline adapters and I connect them like this: Box --> powerline adapter 1 --> powerline adapter 2 --> one of the patch panel sockets --> my PC. First of all, will it work, and will I have the same speed, or is there a chance that it might increase?

      Powerline with fiber is a bad idea, we are far from gigabit speeds.

      Moreover, if the wiring issue with the sockets is not resolved, I don't see why a patch panel would work better with Powerline.

      With Powerline, you put a unit behind the router and a unit in your room.

        The problem is that it's not great, borderline a scam in my opinion. The patch panel connections are probably not functional, I will try to check it out but, well, not much hope...

        If you tried the powerline adapter in the living room => powerline adapter in the bedroom, go through the patch panels. If it worked, don't change anything with the powerline speed.

        Hello. You need to start by checking the continuity of each cable.

        Select two colors, short these two colors on one side, and test with a multimeter if there is contact on the other side.

        If not, there's no need to go any further.

        I rewired the 8 wires; I think it's because the wires were touching the metal end. So then I connected the wiring from the living room socket to my bedroom socket, but it didn't work, and I also tried for my other bedrooms. Thanks anyway, it's progressing slowly but it's progressing.
