Users complain about intermittent wireless connectivity issues.
You see the following message on your Cisco WCS, corresponding the time the connectivity issues occurred.
AP 'building-1-entrance', interface '802.11b/g' on Controller '10.1.1.2'
Noise threshold violated.

A. B. C. D.B.
The message on the Cisco WCS indicates that the wireless AP in the entrance of building-1 is experiencing high levels of noise. This noise could be coming from a variety of sources, including other wireless networks, microwaves, or Bluetooth devices. The noise is likely causing intermittent connectivity issues for users in the area.
To address this issue, the best course of action would be to use a spectrum analyzer to identify the source of the noise. This would allow the network administrator to determine whether the noise is coming from an external source or an internal device.
Once the source of the noise is identified, the network administrator can take steps to mitigate the issue. For example, if the noise is coming from an external source, the administrator may need to work with the building management to reduce or eliminate the source of the noise. If the noise is coming from an internal device, the administrator may need to relocate the device or install shielding to reduce the impact of the noise.
Option A, increasing the interference threshold, would not address the underlying issue of high levels of noise. Instead, it would allow the AP to continue operating in a noisy environment, potentially causing further connectivity issues for users.
Option C, checking for rogue devices and turning on rogue mitigation, is not directly related to the issue of high levels of noise. While rogue devices can cause interference in a wireless network, they are not the cause of the noise threshold violation in this case.
Option D, increasing the power of the APs in the entrance hall, would not address the underlying issue of high levels of noise. In fact, increasing the power of the APs could potentially make the problem worse by increasing the amount of noise in the area.
In summary, the best course of action would be to use a spectrum analyzer to identify the source of the noise and then take appropriate steps to mitigate the issue.
