Which factor is not likely to affect the performance of a Wi-Fi network during peak usage times?

The PoE (Power over Ethernet) capability of the switch primarily relates to the delivery of power to devices such as access points and IP cameras over the Ethernet cable. While it is essential for ensuring that network equipment receives adequate power, it does not directly influence the performance of the wireless network itself during peak usage times.

In contrast, factors such as the number of connected devices, interference from electronic devices, and the overall demand for bandwidth play a crucial role in determining how well a Wi-Fi network performs, especially under high user load. A high number of connected devices can lead to congestion and reduced throughput as they compete for resources. Interference from nearby devices can disrupt signals and degrade performance, while the demand for bandwidth indicates how many users are actively using the network at a given time, impacting available speeds and reliability. Thus, while PoE is important for operational functionality, it does not directly affect the performance of a Wi-Fi network during peak usage.
