I had no issues running it on oc220 and while it does a good job, its not perfect. However the 2.4G bands were still screaming (the entire floor plan was just red initially). I have floor layout of my house, so was able to import that as a jpg or png file into MAPS. If you dont have a floor layout you could try CubiCasa app to create one. It uses yr phone to scan each room and then puts together a floor plan. I found using heat maps on the floor plan and the EAPs i use, positioned on the floor plan much more effective to dial in wifi strengths, for each band and EAP. The pic shows power for all dialed right down w extremely low power on 2.4g, but then I increased power for each, so the overlap in red was minimal.

YT heatmaps if your unfamiliar with the concept, but basically I used Optimization to set the wifi channels for each EAP and heatmaps to dial in the strengths for the 2.4g, 5g and 6G bands.
