The 5GHz radiofrequency is best for both streaming and playing games on computers and game consoles because it has a less crowded frequency band. This is especially true if you have simultaneous streams or several people gaming at once. The 2.4GHz frequency is a good option for devices that don't support 5GHz, like older smartphones and tablets. It's important to remember that 5GHz might be faster, but it won't reach as far. The 2.4GHz band will be slower but extend farther, which means that if you're gaming or streaming, you want to position your device closer to the router so you can take advantage of the 5GHz frequency band.
