What should you do if a cable is found to be faulty?

When a cable is determined to be faulty, the most appropriate action is to replace the cable. This approach ensures the integrity and reliability of the network connection. Faulty cables can lead to signal degradation, data loss, or complete connectivity failure, which can significantly disrupt network performance and operations. By using a new, undamaged cable, you eliminate the uncertainty associated with repairs and minimize further troubleshooting.

Repairing a cable with electrical tape is typically not advisable, as it may not restore the cable's original performance and might lead to recurring issues. Similarly, reconfiguring network settings or adjusting router settings might not address the root cause of the problem if the physical connection is compromised. These actions would not resolve the underlying issue associated with the faulty cable itself. Hence, replacing it is the most effective solution.
