Hey @Jobsp, This KB gives some brief overview on what DFS is and how APs behave when the DFS event is detected. To mitigate negative impact on the network, you can deselect DFS channels from AutoChannel selection as mentioned in that KB. Note, however, that this will leave you with fewer channels and may be challenging in dense environments. Based on my experience, DFS events can be detected pretty much everywhere. Usually, they can be caused by Radars, but sometimes there can be some device in the environment that is generating signals that are legitimately detected by the AP as DFS event, so hitting DFS event from time to time is normal.
