Most likely, many of the owners of computers with Internet access via a dedicated line encountered a problem when, due to one awkward movement or poor-quality crimping, the cable simply fell off the computer, and the Internet, accordingly, disappeared. In this case, it’s very long to wait for the arrival of the master, and you don’t feel like it, because this problem is easy to solve yourself.

However, absolutely no tools and spare parts can not do here. At the very least, you'll need a new RJ-45 connector, a screwdriver, and a sharpened knife. Further manipulations are a matter of technology.
2
Take the end of the UTP cable that was previously connected to the computer and carefully remove the outer braid from it, about 2-2.5 cm. To do this, you need to make a shallow incision, then pull it off the inner core of the cable and cut it off. After that, pick up the torn RJ-45 and see how the wires were distributed there. You need to arrange the cores in the same order. As a rule, the sequence of veins is as follows: white-orange, orange, white-green, blue, white-blue, green, white-brown, brown.
3
Now you should bring all the wires together in a single row, and then with a knife cut off excessively protruding ends. When this operation is completed, you just need to, like in the RJ-45, plug the cores into a new connector. At the same time, you need to make sure that the ends of the cut cable are evenly and completely gone into each groove.
4
At the last stage, you need to flip the connector. There you will see a small recess running across all eight cores of the cable. Take a flat screwdriver (knife with a rounded end) in your hands and insert it into this recess, then press hard. Thus, you will clamp the wires inside the connector and ensure good contact.
5
Then twitch the cable slightly to check that the cable is crimped securely. If the wires do not hold well and begin to gradually exit the connector, try to push them back and repeat the previous step. If this did not work out, then you will have to get the next RJ-45 and start all over again, so try to be careful.
