Hi,
I’d like to set my RB951-2n to choose the frequency automatically - the least occupied channel. I found the options: Frequency: Auto and DFS Mode.
Is selecting Frequency: Auto enough for automatic selection of the least occupied channel or do I need to select something from the DFS Mode?
Thank you

No need for dfs when using indoors without additional high gain antennas.
Thank you 
Don’t forget to use regulatory domain settings.
You mean selecting frequency-mode: regulatory-domain and country: my_country to limit the available channels and maximum transmit power?
Yes.
