Question: is nest 2.4 or 5?
Answer: Nest products (and most Wi-Fi products) only connect to one Wi-Fi network at a time, whether that network uses the 2.4GHz band, the 5GHz band, or both. If you have a dual band router that's broadcasting on both bands, Nest products should work fine with it. However, some Nest products only work with the 2.4GHz band.
