This is a contradiction. The whole point of DFS is "if you detect radar on this frequency you must stop transmitting on it". This is typically followed by a change of channel to avoid an outage of the Wi-Fi, hence "dynamic frequency selection".
I know how it works. Static was the wrong word, but my current router (Netgear) lets you set a primary DFS channel, and based on my tests, the channel selected does affect performance.
As far as I can tell, there isn’t even a way to perform auto DFS selection on my current router.
