I replaced the connector, the Internet disappeared, why?

Question

Computer networks

Everyone is great, friend. I recently damaged my internet cable that goes from the shield to the apartment and decided to repair the whole thing. And I bought a toolless connector, where you just need to put the wires (into the grooves) and slam the lid, which will cut through the insulation and create a connection with knife contacts.



As you can see in the photo, there is a hint of what and where to put (color scheme). Using it, of course, I did not get any result, because judging by the answers here, the craftsmen are recruited from the street, and they crimp the connectors to hell. Therefore, I called each contact and made a color matching chart, which color should fall into which groove.

The color scheme of the provider is like this (if you look at the connector from above from the side of the latch):

коричневый бело-коричневый синий бело-зеленый зеленый белосиний оранжевый бело-оранжевый

In accordance with this scheme, I assembled the connector and also did not get a result. The light on the router is flashing orange. When connected directly to the computer, it is also deaf.
I went further and cut off the insulation from the ends of the wires and reconnected it so that the contact area was larger. Nothing.
Then I began to read the theory that paired cores should be twisted together with a certain pitch, but I don’t know what paired cores I have, so I just wrapped them around by color and drove them back into the connector. In short, nothing happened again. Yesterday, before going to bed, the idea came up to look into the provider's shield in order to ring the integrity of the entire cable.

Nobody knows what could be the problem?

Answer 1

What is a contactless connector? If it's cheaper than 150 rubles apiece, then you can just throw it away. Call the provider, he will come with a good crimp and connectors. Without crimping or expensive "field crimpless" connectors will not work.
Well, in the case:
- you only need to remove the outer sheath
- you don’t need to expose the contact conductors
- you can’t unwind the wires more than 3 centimeters from the connector
- after removal, carefully align all the wires, sort out the wire pairs according to the colors
- the colors can be according to annex A or annex B (usually the second), but they are not interchangeable, it is better to look on the other side of the cable
- two pairs of annex B are intertwined in the connector white-blue - blue and white-green - green!
- the cores themselves according to annex B: white-orange - orange, white-green - blue, white-blue - green, white-brown - brown
- we evenly cut the decomposed pairs according to colors and fill them into the connector, if the connector is field, then after inserting we make an additional even cut, crimp or press down the cover.
- check with a tester or insert into a computer port

Answer 2

What about the old connector? See how it is crimped and crimp it the same way.
The correct Feng Shui crimping scheme is:
white-orange, orange, white-green, blue, white-blue, green, white-brown, brown.
See the colors by turning the connector with the contacts facing you and up.

I know.

(It was a joke)
No need to reinvent the wheel - you need to call the provider. The disappearance of the tyrnet directly is unprofitable for them - they take the money, the service does not work. A specially trained person will come and do everything.

masters are recruited from the street, and they crimp connectors to hell

Yes, it happens. Everyone adheres to the same scheme simply because it is so convenient, but nothing prevents them from crimping according to the "half-finger-ceiling" scheme, if it is the same on the other side. True, it may not work :) It
is also necessary to call a specially trained person for this reason.

I know.
Grandfather Krylov wrote about you 200 years ago "" It's a problem if the shoemaker starts the pies, And the pieman makes the boots." I stupidly called the provider, and this despite the fact that I have a good cremper and a couple of dozen high-quality connectors

I bought a toolless connector,

And I always thought who buys this shit
