A network administrator recently upgraded a wireless infrastructure with new APs. Users are reporting that, when stationary, the wireless connection drops and reconnects after 20 to 30 seconds. While reviewing the logs, the administrator notices that the APs are changing channels. Which of the following is the most likely reason for the service interruptions?
Show answer
Answer: A
Explanation
the disruption or degradation of a wireless signal caused by other devices operating on the same or overlapping radio frequencies (channels), leading to reduced network performance like slower speeds and unreliable connections Overlapping channels: Most commonly, interference occurs when nearby APs are set to channels that partially overlap with each other, causing signal collisions. Multiple sources: Interference can come from various devices like other Wi-Fi networks, Bluetooth devices, microwave ovens, or cordless phones operating on similar frequencies. Impact on performance: When interference is high, devices struggle to receive clear signals, resulting in slower data transfer rates, packet loss, and increased latency.
