Is there any way to really capture a wifi log (with all status changes etc.) ?
The facility in webui is only a status report, and not a log.

Just indicating the DFS channels - they have to passively search for the appropriate waveforms related to certain radars before they can start transmitting...

Linux on client adapters might show something like below - same approach - No IR means not Initial Radiation...

        Frequencies:
            * 5170 MHz [34] (disabled)
            * 5180 MHz [36] (20.0 dBm)
            * 5190 MHz [38] (disabled)
            * 5200 MHz [40] (20.0 dBm)
            * 5210 MHz [42] (disabled)
            * 5220 MHz [44] (20.0 dBm)
            * 5230 MHz [46] (disabled)
            * 5240 MHz [48] (20.0 dBm)
            * 5260 MHz [52] (20.0 dBm) (no IR, radar detection)
            * 5280 MHz [56] (20.0 dBm) (no IR, radar detection)
            * 5300 MHz [60] (20.0 dBm) (no IR, radar detection)
            * 5320 MHz [64] (20.0 dBm) (no IR, radar detection)
            * 5500 MHz [100] (20.0 dBm) (no IR, radar detection)

DFS channels are all clearly marked "RADAR sensitive".
"Passive" must be something else (maybe off-channel CAC ?). But comes and goes in an inexplicable manner.

Just bumping up, related to original point (2):
Any way (script, command whatnot) to log wifi events (DFS radar detections, channel change etc.) ?
