A:Answer Hi! The Deco M4 utilizes intelligent algorithms and band steering to help ensure optimal connectivity to Deco nodes and Wi-Fi bands. That said, a large role is still played by the Wi-Fi client devices (phones, laptops, etc.) in prioritizing one band over the other. Some devices will have Wi-Fi options/settings that allow you to configure a priority or preference for 5GHz or 2.4GHz.
