What amazes me is how many "new" devices can only work on 2.4 GHZ. My pool robot and the WiFi Thermostat (which I really didn't want) are 2.4 GHZ only. I think they are the only things that connect at 2.4 GHZ.

2.4 is for distance, 5 is for speed
Those remote devices use 2.4 because they are generally the farthest away, only pass small packets of data.
They don’t need a more robust connection and actually perform better over 2.4
