What is the mistake in dividing the network cable into a double network socket?

Question

Computer networks

Can you please tell me where is the error in this method? I divided the network cable into two connectors, connected it similarly to further actions to 1,2,3 and 6 connectors. Next, I connected the cable to a power outlet (similar to the one in the screenshot). Then I ran 2 cables differently crimped to two computers. But the network is not working.
(no info on the screenshot - earlier, while near the switch, the cable was standardly crimped white op., op. white. green, green, white. blue, blue, white. short, short on one of the computers, which on the screen above, the network worked).
Please advise, thanks in advance!

Answer 1

the error is that you don’t need to do this
if you really want to - then check that the 1,2,3,6 contacts on the connectors in the computer and in the switch match. nothing is clear from your pictures

crimped standard white op., op. white green, green, white blue, blue, white cor., cor.

what kind of standard is this?

Doing so is a violation of the standard. And only the phone will work on such a "link" :) Regular FXO, not IP. For phones, I did such a perversion myself :) Four FXOs on one UTP :) And trying to start something other than a phone on this is nonsense.

Answer 3

Most likely a defect in the cable. I myself encountered a situation where the tester shows a complete order, and the connection fails or is not established.
On the other hand, I see that you have already been advised here that they say you can’t do this, but why? We look at the requirements for category 5e twisted pair and see that they are the same for all pairs, regardless of their color. Therefore, we can use pairs to connect the network in any order we like. If I'm wrong, proofs to the studio!

Answer 4

Only recently I tried to do this, it was necessary to install a couple of printers for a week, and drag cables 50 meters around the warehouse. So, even on pairs of orange and green, the link did not rise (blue and brown, similarly).
Moreover, everything was correctly compressed according to the fluke, but this option did not pass the test even at 10mb.

Answer 5

I did this, everything works fine, change the cable socket of the hand
