Here’s an example of what a scan on a MoFi router gives you (from https://www.youtube.com/watch?v=cEUniVG3oLc). Even without any styling it’s still very useful, and having a single scan spit out what it captured at the time is far better than manually toggling off bands, waiting for a soft reset / reconnect, etc.
This obviously pushes you to try band2 (which is generally a good idea) - only 3db less than b12 but more bandwidth, and far more bandwidth than b5. If b2 was -130 or something then things are different.
