How to activate my RJ45 sockets?

Solved

Hello everyone,

First of all, I would like to apologize for the lack of information or any inaccuracies, but I'm not knowledgeable about this at all.

I would like to use my Ethernet ports, but they are not working, as if they are not activated. While searching online, I saw that it was a matter of wiring, but I'm not sure which one applies to my case.

1- My internet box (fiber) is connected to an Ethernet port in the living room. It seems to be working since the corresponding light is on my box.

2- My communication cabinet is on a different floor.

There you go, I don't know if I can provide more information or photos.

Thank you!

Hello,

In the first photo, in the middle left, you have the fiber arrival point, the PTO (Optical Termination Point). This is connected by a green-ended fiber cable (your second photo) to the ONT (which converts the optical signal - fiber - into an electrical signal - Ethernet). From the ONT, a red-ended Ethernet cable goes to patch panel No. 1 (third photo). This patch panel should correspond to the wall socket in the living room to which the box is connected. This connection is used to bring internet to the box. It does not allow internet distribution to the other wall sockets.

On the patch panels, ports 2 to 8 (it would be better to see them) there should be small cords that are connected to each other (a sort of octopus) that go to the DTI. The DTI and these cords were only used for ADSL/Telephony. They are no longer used. You need to remove all these cords and not use them for Ethernet.

In principle, the box should have been installed in this communication box, so we would have connected the Ethernet outputs of the box to the patch panels feeding the wall sockets.

In a property with a building permit since 2016, there should be 2 wall sockets in the living room. Then we connect an Ethernet cable from one output of the box to this second wall socket. This should connect to patch panel No. 2. On this patch panel, we connect a Switch (Ethernet port multiplier) which will allow us to power patch panels 3 to 8, and the corresponding wall sockets.

Without a second socket in the living room, it's impossible to route the network down to the communication box to supply all the wall sockets.

First of all, thank you very much for this explanation.

If I understood correctly, I need to unplug sockets 2 to 8.

In my living room, I have a standard ethernet socket as well as a socket with a telephone symbol (I feel like they look similar?). Is this what you're referring to?

You need to make sure that this second socket is indeed an RJ45. This should be verified visually. That would be good news.

Then connect an Ethernet cable between an output of the box and this second wall socket. Then do a test by connecting a PC directly to the patch panel. With a bit of luck, it’s the No. 2. Or could there be numbers on the wall sockets?

This test should help validate the network return to the communication box.

Thank you, I will try this tomorrow.

There are indeed numbers on the wall sockets, the one in my living room being number 1, on the panel it is connected to a red cable (different from the others). One silly question, for the verification, do I unplug the cable and connect it to my PC or do I plug in a new Ethernet cable?

on patch panel No. 2, you will need to remove the existing cable, no longer use it, and connect a new Ethernet cable between patch panel No. 2 and the PC

Hello,

I just tried and there is indeed a port that works!
If I understand correctly, all I need to do is buy a switch, connect it to this port, and then connect Ethernet cables from the patch panel to the switch?

Your installation needs to be done correctly.

Yes, a switch is the right solution to multiply the ports. Get one with 8 ports like: https://www.amazon.fr/TP-Link-TL-SG108-Switch-Gigabit-Bo%C3%AEtier/dp/B01EXDG2MO/ and Ethernet cables to go with it.

In the meantime, if you want to use a socket in one (single) room, you can create a bridge on the patch panels, for example, by connecting a cable from socket 2, coming from the living room, to socket 4.

Now, with a very fast fiber subscription, 2.5 or 5 Gb/s, when the box also has an output port of 2.5 or more, and when you want to have this ultra-fast connection on a PC, especially for gaming, you could set up an installation with over Gigabit (if the cabling supports it). You would then need to get a switch like: https://www.amazon.fr/TP-Link-TL-SG108-M2-Switch-Bureau-Ports/dp/B08WQ16H4N/
Let's say this is a more efficient solution for the future.
You should check the speed you are receiving on your box, and whether it has a 2.5 Gb/s Ethernet port or more.

By staying in one room connecting the two ports, it works! So I’m ordering the switch.
However, when I tested it the first time I was at about 600mbps down and since then I'm stuck at 90mbps, it might be because of my cable?
In any case, I thank you so much, you’ve helped me a lot!!

600 Mb/s with the PC in the communication box and 90 Mb/s with the same PC in a room and bridging on the patch panel?


It shouldn't be the cable running through the walls. As for the Ethernet patch cords, try several by swapping them out; we can validate them one by one by directly connecting the PC to the router.

It could rather be the wiring of one of the 2 sockets (patch panel No. 3 or wall No. 3, 3 being an example depending on the tested room). The cable has 8 wires, essential for Gigabit Ethernet (1000Mb/s); if one of the wires is poorly wired in a socket, we could end up with a 100Mb/s connection, which uses only 4 wires. We should test several rooms.

No, 600 mb/s in the box and also testing in one room, since then it has been stuck at 90 mb/s even when testing in other rooms.

I tested by connecting directly to my box and there I found a speed of 600.

However, I noticed that one of the Ethernet lights on my box directly connected to the RJ45 socket was off, maybe something I unplugged in the box or an installation issue?

The lights on the box can only be on if there is a device (PC, switch) connected at the other end.

I see, so I can't find the problem and why I lost so much bandwidth since my cables are working

it's only you who can assess what has changed before/after

quietly redo some connections and tests

or someone at your place is downloading files and saturating the connection ;-)

I tested several cables and several outlets, whether in a room or directly connected to the patch panel, the speed remains the same; unfortunately, I cannot find a solution :(

Thank you very much for helping me.

But you did start with 600Mb/s on the patch panel, right?

How do you run the test?

0
siyak Posted messages 12 Status Membre
 

Yes, the first time, whether it's through brewing or taking, I'm at 90mbps.

I plug an Ethernet cable into my PC and then I test on Speedtest, I also tested with a console and Ethernet and I got the same 90mbps.

Moreover, in the ethernet connection properties on my computer, the connection speed is 100/100 mbps

Hello siyak,

If you're getting 600 Mbps by connecting your PC directly to the Box and 90 Mbps by connecting to the RJ45 sockets in the rooms, it definitely points to an issue with your installation:

Either the cables in the walls are 4-wire, or the RJ45 sockets are not wired correctly, as jee pee pointed out to you.

You need to check each RJ45 socket and each cable in the walls.

This is the whole problem of wanting to upgrade to high speed with an installation designed for telephony...

Even when connecting to the switch, I'm still limited to 100mbps. So I feel like I don't really have a solution, thank you for the help.

If this happened on 600 in the patch panel at least once, then after 90 we can suspect there is a defect in the wiring either at the wall socket or at the patch panel. The simple act of connecting/disconnecting a cord may be enough.

We should open the living room wall socket; it might be the easiest to dismantle, and check the wiring of the socket. Depending on the model, we will need a photo of each side, where we have the color and number of wires on the connection block.

You said above:

I tested by connecting directly to my box and there I get a speed of 600.

So directly from the box you have 600 Mbps and at the patch panel you have 100 Mbps:

There is therefore a problem between the box output and the patch panel...

If I understood correctly, your internet signal coming out of the box goes to the patch panel to be distributed to the rooms; it might be this cable that has 4 wires or the RJ45 sockets not wired correctly, which limits your speed to 100 Mbps.

Please check this cable (the number of wires) and the wiring of the RJ45 sockets.

PS: sorry jee pee I hadn't seen your reply, we're saying the same thing

Hello,

The beginning returned to normal a few hours later and since then there have been no more issues. I didn't really understand the problem, but anyway! Since then, I have completed the entire installation, including the switch, and everything is working very well. Thank you, you have been very helpful!
