I really wish I had the option to completely disable the 2.4 GHz Wi-Fi radio since there are so many networks and it clutters up the list when I'm looking at it. If I could just turn it off and do five gigahertz only, my network's list would shrink a lot and that would be a lot more helpful.
How often do you look at the wifi list? It would be more useful if we could lock one SSID to one specific band (2.4/5/6 GHz). This could help for devices that frequently switch between bands
It's a hack, but if your phone has dual band radios you can turn your hotspot on for one band, which will force your wifi client to only use the other band to look at networks.
