Network Ethernet RJ45 cable repair pictorial

1- This network cable plug is broken and doesn’t hold properly anymore into the RJ45 Ethernet socket. 
2- You will need this specific tool widely available and that crimps RJ connectors, both for telephone and network.
3- The RJ45 connectors are available with or without metal to be used respectively on shielded and unshielded patch cords. 
4- The above shows how to prepare a shielded cable. Cut the plug and remove around 10 mm of insulation. 
5- You can now see the shield (the blue aluminum foil) around the wires. The same method applies  for unshielded cables. 
6- Start opening the shield. A transparent layer also wraps the wires. Proceed layer by layer. 
7- Continue opening the shield without tearing it or cutting it.  
8- Pull it down and wrap it around the cable. Observe well the bare wire which has to be bent down above the shield. 
9- Now unfold and cut the transparent layer. 
10- Look at the connector on the other side of the cable and see how the wire colors are arranged into it. 
11- Do the same color order arrangement. There are 4 colors each with one plain and one white-striped wire. 
12- Cut all wires to the same length and push them into the connector making sure each goes till the end of its channel. 
13- Also make sure the bare wire is in touch with the metal part of the RJ45 connector and insert the latter into the crimping tool. 
14- Press the tool until you hear a “click”.


​
15- Your LAN network patch cord (RJ45, Ethernet) is now repaired and ready for use.
