5 GHz WLAN craps out (upon radar detection?) - start_dfs_cac() failed

If I only provide other DFS channels as fallback, will there be a 1 minute delay before wifi can come back online?

That is not possible for VHT160. If channel 36 is available for fallback it will stay there forever as there is no DFS event...

@hnyman It is pointed out also in this github issue. I write a small script that detects an issue and restartes wifi but would like to see a channel 36 fallback with switch to DFS channel automatically in hostap.
