RADAR does not bother his routers as they do not use DFS channels.
Strange but the AC68U at a not for profit i managed did not have DFS channelsRT-AC66U B1 only doesn't have DFS support.

And here some recent Radar Detection entries in the System Log:Available channels are region and law dependent.
My RT-AC68U definitely has DFS, I have seen 5 GHz channel changes in the system log with a description like "radar detection".
The RT-AC1900U as Media Bridge I did have, appeared to have troubles with automatic 5 GHz channel changes, I finally changed the connection to 2.4 GHz at a fixed channel, and after all discarded the Media Bridge completely (the RT-AC1900U is now stored as spare and experimental box).
