Discolouration and poor resolution are very common issues users face in such situations. This is yet another sign that your broken LAN wire is not working properly and requires your immediate attention.

3. Cluttering and Wiggling the Wire

If the cable is in pristine condition, then wiggling it will not cause much problem unless it is detached from the port. However, twisting and wiggling an old wire can cause damage, which would eventually make your internet connection slow or dead, in worst scenarios. Therefore, it is best if you avoid wiggling the wires.

Now, you may think that if you do not wrap up the wires correctly, it will create a clutter, which you do not want.

Wire cutters can be easily avoided if you manage the cables with paper pins. Simply hang some paper pins on your computer table and hook the wires individually in them. This would enable you to enjoy a clean environment with no damage to your LAN wire.

4. Inconsistence Performance of the Network

LAN wires that are in good condition will always deliver consistent performance unless there is an issue from your provider.

However, if you are facing varying performance patterns, then chances are that something is wrong with your Ethernet cable, which is why it is failing to deliver the desired speed and bandwidth. Therefore, check for the consistency in the performance of your connection so that you can make the necessary changes beforehand to your broken LAN wire

5. Check the Wire With a Tester

You can also check the Ethernet cable with a wire. Simply purchase a cable tester from the market and attach it to the cable. Most testers have two sets of eight lights. These lights correspond to the eight pins on the transmitting and receiving end of the cable. The tester will check each and every pin of the cable individually. If all the pins light upon both the ends, then the cable is good.
