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?

Roaming misconfiguration typically involves issues with how devices transition between different APs, which can lead to dropped connections. However, in this situation, the logs indicate that the APs themselves are changing channels rather than users moving between APs. Thus, while roaming can cause issues, it is not the primary cause here.

Network congestion refers to a scenario where too many devices are attempting to use the available bandwidth, resulting in slower speeds and potential disconnections. While this can impact wireless performance, it does not specifically explain the channel-changing behavior of the APs, making it less likely to be the root cause of the interruptions observed.

Insufficient wireless coverage occurs when there are not enough APs or the APs are poorly placed, leading to weak signal areas. However, users experiencing drops and reconnections due to insufficient coverage would likely not see APs actively changing channels. Therefore, this option does not adequately explain the situation.
