Hi everybody
I m trying to setup a link in a very noisy media , i tried to use spectral scan to select best choice but i didnt know how ?
also i read that if we choose x-polarity it may behave better than dual polarity so how to select that ?
these are the spectral scan of mine :

You should be able to go to the wireless config, go to the HT tab and disable chain 0 or chain 1 then scan, not sure which is horizontal and which is vertical though.
