A corporate channel has a high noise floor and no extra beacons. A rogue access point is beaconing the corporate SSID on a different channel. What is the noise on the corporate channel?
Select an answer to reveal the explanation.
Short Explanation
The rogue is talking on a different channel. The noise on your corporate channel has no beacons in it, so it is something else. Do not spend the ticket on the rogue and leave the noise sitting there.
Full Explanation
A rogue is identified by its beacons. This one is beaconing on a different channel. The corporate channel has a high noise floor and no extra beacons, so that noise is not the rogue. A rogue does not raise every channel at once just by existing on one channel. Noise without beacons is not a coverage hole. A hole is weak signal from your own radio. A low beacon count is not a radar detection. DFS is a specific 5 GHz reaction, not a synonym for a quiet SSID list. A rogue is beaconing on a different channel. The noise on the corporate channel has no beacons. The rogue is not the noise. Check one live client after the change and leave the rest of the floor alone until that client matches the result you expected. Confirm the symptom on the next attempt before changing anything else. Exam caveat: the rogue on the other channel is still a rogue and still needs to be handled. It is just not the explanation of this channel's noise. Operational check: use the spectrum view on the noisy channel, find the non-beacon energy, and deal with the rogue as a separate item.
