I am looking to be a good neighbor and limit the number of RF channels my Deco uses. 

Normally on other products I can set the RF bandwith to say 160Mhz which is three 2.4Ghz channels or 150Mbs

I was looking at my channel useage and noticed my deco was using all 2.4Ghz bandwidth.   

How do I set the RF bandwith like setting the maximum datarate of say 150Mbs?

This is the scan show channels 1-8 are being used by the Deco.

My old system old used three channels
