2.4 GHz vs 5 GHz vs 6 GHz Wi-Fi: Which Band Should You Use?

Modern Wi-Fi routers often advertise two or three frequency bands: 2.4 GHz, 5 GHz, and, on newer equipment, 6 GHz. They all carry network traffic wirelessly, but they behave differently when it comes to range, speed, congestion, and compatibility. There is no single “best” band for every device. A phone in the same room as the router has different needs from a smart plug two walls away. Understanding the trade-offs makes it easier to diagnose slow connections and place devices on the band that suits them best.
