What could cause an intermittent internet connection?

An intermittent internet connection can often be attributed to issues such as loose cables, interference, or equipment failure. These problems can disrupt the signal and cause fluctuations in connectivity. Loose cables may not establish a stable connection, leading to dropouts. Interference from nearby electronic devices, physical barriers, or overlapping Wi-Fi networks can also weaken the signal strength, causing interruptions. Additionally, equipment failure—whether it's due to aging hardware, firmware issues, or malfunctions—can result in an unreliable internet experience. This combination of factors makes option B the correct choice, as they directly relate to the technical elements that impact internet connectivity.

In contrast, strong Wi-Fi signals, upgraded equipment, and consistent power supply generally contribute to a reliable internet connection. A strong signal indicates good connectivity, while updated hardware is designed to handle network demands effectively. A consistent power supply ensures that devices function continuously without unexpected shutdowns, which normally supports a stable internet experience.
