Does Nest thermostat work on 5g?

Nest products (and most Wi-Fi products) connect only to a Wi-Fi network at the same time, this network uses the 2.4 GHz band, the 5 GHz band, or both. If you have a dual band router that broadcasts in both bands, Nest products should work well with it. However, some Nest products only work with the 2.4 GHz band.
