I have a Google WiFi router so it assigned the correct band (2.4 or 5) depending on the deivce connection and its signal strength. For most of my phones/tablets in the house it uses 5 GHz. 2.4 only kicks in for devices that can't handle 5 GHz (My thermostat/smoke detector/etc.) or if you walk far enough to make the 5GHz network weak it will swap you to 2.4 due to the range.
