Split Ethernet cable - two devices on one twisted pair

Question

Hello.
I have a Toya modem in one room.
From it comes the cable to the router in the other room.
I have a PS4 in this room with a modem.
I need a cable to connect the internet to the ps4, but from the modem.
What do I need to buy to connect the modem router to the line and bring the cable to the console?
I know I could from the router, but then I would have to run a 10m cable in the strips and through the wall and that's too much of a hassle.
Please help.
Regards [/ code]

Buy a LAN splitter, cost ~ 10 PLN or make it yourself. You can find the diagrams in the search engine.

I see. It's cool how such a low cost

m.jastrzebski · Answer

As above. 2 x RJ45 splitter. Just a small note. If I got you right. From two such distributors, you will make 2 100mbit connections in one cable. And now with this 100mbit connection you connect the modem output with the router's WAN input. And with the second cable you connect one of the LAN sockets of the router and Return to it, near the modem, connect it to the PS4.

From the modem you will not connect to the PS if you have a router. - As a colleague wrote above, such a combination of the return signal should be made with the router's WAN cable - it can be done as much as possible, you just have to surprise the idea itself.

the_eye777 · Answer

Well, I don't have to buy anything, only pull the cable from the router and that's it

m.jastrzebski · Answer

This is how I understood you that you do not want to pull this cable because it is related to some demolition, forging or drilling.

the_eye777 · Answer

Well, my point is to leave the modem

m.jastrzebski · Answer

It was you Hermes who wrote that you can't get out of the modem.

the_eye777 · Answer

Well, once that I am far from the router, and two that I would have to hide the entire cable under the slats

Added after 1 [minutes]:

Well, I understood that I can not leave the modem.
And what would I have to connect a modem router on the line to get out of this? Second router? Because I have one not used at the moment

m.jastrzebski · Answer

You have to buy 2x splitter for a few zlotys. The cable you have connected to the modem -> the router has 8 wires inside. You use 4 wires to connect the modem + router. You use the remaining 4 wires to release the connection from the router in the other room from the LAN socket. Splitter only splitter of 8-wire cable into two 4-wire plugs.

the_eye777 · Answer

Oh, now I understand. It is on one cable that the signal will be distributed

m.jastrzebski · Answer

NOTHING will break apart there. The signal splits the router. On different wires inside the twisted pair, you will make 2 different connections in a way that is totally independent of one another. As if you had 2 cable to connect the router to the PS4. As if you wrap 2 cables in one insulation.

the_eye777 · Answer

Approx.
How do I buy these 2 distributors, how should I connect them?
And how are these distributors supposed to look like? Are they to have only female entrances or what? Because there are some of them on the net and there are those with 1 plug and 2 inputs

m.jastrzebski · Answer

I connect yes. I take the splitter in my left hand into my right cable and press it and I will hear click. And for real. Take se and draw what you have been translated 5 times, so it couldn't be easier. If you don't know from the drawing, I won't be able to help; (

LucekB · Answer

You can buy 2 such splitters and then you need 4 more short RJ-45 LAN cables (patchcord) and plug the cables from the socket.

Instead of a splitter, you can do it yourself with a crimping tool and RJ-45 terminals, where you can buy one for home works for PLN 20-30.

dedito · Answer

These splitters still need to be converted to serve as LAN splitters.

LucekB · Answer

They will be described with splitters and this is what the author of the post should stick to: the_eye777 Such as these

dedito · Answer

So in a way, on the example of the photo above: 1. You are buying a set of such splitters (they are sold in pairs). 2. Disconnect the cable from the modem and connect it to the LAN socket in the first splitter. 3. Connect the modem cable to PC1 (in the place where the router cable was previously) 4. Connect the PS4 cable to PC2 5. Disconnect the cable from the router and connect it to the LAN socket of the second splitter. 6. To PC1 you connect the router cable to the WAN port (in the place where the modem cable was previously) 7. Connect the cable to the router to the LAN port to PC2.

What is your internet bandwidth from ISP? Because if it turns out that 250Mb / s, you will shoot yourself in the knee with these splitters and all this smack.

nici · Answer

Why so much trouble, if the PS4 has WiFi, which, by the way, is better than LAN?

the_eye777 · Answer

It has WIFI, but I have a download speed of 3-4Mb wirelessly and 10 on the cable. Ok, I know everything. Thanks a lot for your help. Tomorrow I will get it when I buy these tees. And I have 100Mb net

jprzedworski · Answer

And not better to give a switch?

nici · Answer

I have identical connection parameters.

Przemek2011 · Answer

It's not easier to move this router to the place where the modem is?

the_eye777 · Answer

I live in a block of flats, there are probably about 20 networks around, each generating interference. In the place where it stands now, I have the best range in the whole apartment, it does not break my connections, etc. Subject solved. Can be closed.
