Hi. Is there someone, who can tells me how to scan for best channel, for noise around every channel, and channel quality.

I made this:

wl rm_req cca -c 1 -d 100 cca -c 2 cca -c 3 cca -c 4 cca -c 5 cca -c 6 cca -c 7 cca -c 8 cca -c 9 cca -c 10 cca -c 11 cca -c 12 cca -c 13 cca -c 14

wl rm_req rpi -c 1 -d 100 rpi -c 2 rpi -c 3 rpi -c 4 rpi -c 5 rpi -c 6 rpi -c 7 rpi -c 8 rpi -c 9 rpi -c 10 rpi -c 11 rpi -c 12 rpi -c 13 rpi -c 14
