This DFS and radar detect is killing me. It takes forever to detect radar before an access point starts running. since 6.37 It would appear there’s no way to disable it so I had to downgrade everything back to 6.36. Please mikrotik help!!
You might want to watch the talk about DFS from the MikroTik MUM in London earlier this year: http://mum.mikrotik.com/2016/UK/agenda
Short version: on certain frequency bands, DFS is a legal requirement.
