Wi-Fi band

A Wi-Fi band is a range of radio frequencies used for Wi-Fi, and home networks use 2.4 GHz, 5 GHz and, on newer gear, 6 GHz.

What it means for you

Each band trades range for speed. Many smart plugs, bulbs and cameras only join 2.4 GHz networks, which is why setup can fail when your phone is on 5 GHz.
