Wi-Fi primarily operates on two frequency bands: 2.4 GHz and 5 GHz. These bands provide different attributes in terms of range and speed. The 2.4 GHz band typically offers a longer range and better penetration through walls, making it suitable for general usage in homes and offices. However, it is more susceptible to interference from other devices such as microwaves and Bluetooth devices. On the other hand, the 5 GHz band can provide faster data rates and is less crowded, which can lead to better performance in environments with many devices, although it typically has a shorter range compared to the 2.4 GHz band.

Understanding these frequency bands is crucial for effectively managing wireless networks and optimizing their performance. The other frequency bands mentioned in the options do not correspond to typical Wi-Fi operation. For instance, bands like 1.2 GHz and 5.5 GHz, or 3.5 GHz and 6 GHz, are not standard for Wi-Fi technologies, and 4.2 GHz and 7.5 GHz fall outside of the commonly utilized Wi-Fi bands as of the latest standards. Therefore, the most accurate answer reflects the established frequency bands that Wi-Fi operates on.
