What is an indicator that may help troubleshoot modem issues?

The status lights on the modem are crucial indicators that can help troubleshoot various issues with the device. Each light typically represents different functions such as power, internet connectivity, and data transmission. By observing these lights, you can quickly determine whether the modem is powered on, has an active internet connection, or is experiencing any connectivity issues.

For instance, if the power light is off, it indicates that the modem is not receiving power, which could be a problem with the power supply or the outlet. If the internet light is red or off, it suggests that there is no connection to the internet, pointing toward potential issues with the service provider or the modem’s configuration. These visual cues guide technicians or users in identifying the state of the modem and help them take appropriate actions to resolve problems.

In contrast, while speed test results can provide insights into internet performance, they do not necessarily diagnose modem status. Customer feedback can be informative but is subjective and often lacks the immediate clarity provided by status lights. Manual reads from a cable graph are more technical and may not be practical for everyday troubleshooting. Thus, interpreting the status lights on the modem is the most direct and effective approach to diagnosing connectivity issues.
