Hello everyone,
I have installed two RJ45 sockets in series on a single cable. The cable is installed in the wall and there's no going back from that point of view.
I was hoping to recover from the damage by only connecting one device to my first socket and ignoring the second. Some comments on the forum led me to believe that this solution worked for some people.
Electrically, my installation is reliable, tested with a multimeter; my cables are not cut and are connected in the correct order.
Unfortunately, when connecting my computer to the box via the wall socket, there’s no signal. I’m a bit lost on the causes of the problem and I insist that I’m only using one socket.
Is the issue caused by the two sockets in series? If nothing is plugged in at the end of the wire, it shouldn't be considered dead cable and shouldn't interfere with the installation.
Or should I look for another reason?
Thank you in advance for your help.

Hello,
Of course, that's not how it works.
It might work in telephony at a stretch, but even there you don't do that; you need to bring the ports in parallel to a common splitter.
Did you read on this forum that some said it worked?
Did I miss the chance to yell at them?
How did you go about tapping into one socket from another?
It's physically impossible to put two wires on a wall-mounted RJ45 terminal.
What you can do immediately is remove one socket and rewire the other correctly, cutting 2 mm before the point taken in the CAD.
What kind of cable are you using?
