Show answer and explanation
Correct answer: A
Explanation
The network adapter's status indicator light being off is typically a hardware-level issue, such as a disconnected or damaged cable. This is the most likely cause of the described problem, making it the correct answer. Other options may cause network issues, but they would not directly affect the status indicator light.
- A. Correct.
A status indicator light being off on the network adapter often indicates that the network cable is either unplugged or damaged, as it shows no physical connection to the network.
- B. Incorrect.
While an outdated driver could cause network connectivity issues, it would not directly affect the status indicator light on the adapter.
- C. Incorrect.
A powered-off router could disrupt network connectivity, but the status indicator light on the adapter would still typically show activity if the cable is connected to a switch or other intermediary device.
- D. Incorrect.
An operating system issue could prevent the computer from accessing the network, but it would not cause the hardware status indicator light on the network adapter to turn off.
