On the Access Point View screen, the technician notices that the AP is using channel 11 and the channel utilization is 35%. However, the technician notices that there is no wireless client associated with the AP. What is a possible explanation for the channel utilization?

The CAPWAP tunnel between the AP and the WLC is down.
Nearby APs and clients are also using channel 11.
The AP is operating in FlexConnect mode.
The radio has malfunctioned and is preventing clients from association to the AP.

Explanation: The channel utilization indicates how much of the available airtime is being consumed. If the wireless network is not well deployed, other APs and clients may use the same channel 11 somewhere nearby. If those devices are busy transmitting on channel 11 and this AP is within range to receive their signals, the AP will note that the channel is in use.
