dfs still not working on Beta8

I got the bwta8 on som etest sites but DFS still not working. In fact the wireless select everytime the firs frequency into the scan list, also if it is used by an adiacent AP.

So please take a look into it. This is my wirelss config:

DFS is only for radar dectection – other APs don’t make a difference.

why this behavior???

in 2.9.x it is a good tools to autoselect the best channell and it detect also used chennels by close AP.

And then why there are DFS with no radar detect and with Radard Detect if it is only about radar???

Any explanation is welcome.
