What is typically the first step in troubleshooting coaxial cable issues?

The first step in troubleshooting coaxial cable issues is typically to inspect for physical damage. This approach is fundamental because physical damage to the cable, such as cuts, kinks, or abrasion, can severely impact signal quality and transmission. A damaged cable may not conduct signals properly, which could lead to loss of service or degraded performance. By visually examining the cable, you can identify obvious problems that could be the root cause of the issues being experienced.

Furthermore, while verifying cable connections, measuring signal strength, and checking for interference sources are also important troubleshooting steps, they come after confirming that the cable itself is intact. If physical damage is present, it needs to be addressed first, as repairs or replacement of the cable may be required before further diagnosing the other potential issues.
