RF Spectrum - AP looks interfering with itself

[AndreaAvataneo]

Hello to the Forum,

I've noticed in our Meraki infrastructure a strange behavior on the RF-Spectrum.

Basically, it seems that every AP is interfering with itself.

I've already tried to redo a channel scan; we also have the Auto RF scan but after a week the problem is still there.

It happens in 2.4Ghzand 5Ghz.

Model affected are MR44, MR46E, CW9162I, MR36H 

Model MR78 is not showing this behavior.

all model with last OS version 31.1.5.1

Thanks for your help and suggests
