Hi Antonio,

We have Support people available to answer chat or email to help you look at your settings and spectrum. If you want help from the community here, then you’ll need to share the same details in public including a screen capture of the Dashboard and Channel & Power pages. These will show us the number of channels, frequency, bandwidth, PER, SNR and spectrum.

Of course should share here without some privacy. Other ways how people can learn from here!
