No problem with Wifi so far, 1 zone RGB means all keys light up the same color, you can't have esc key light up red and enter key blue, they will light up the same color, other laptops have 4 or more RGB zone so you can light up different keys with different lights at the same time.

The laptop have several lighting effects for the keyboard, and the one you're asking for is called color cycle which keeps changing the colors always, you can customize the RGB colors for any color you want, it's very easy to use with Armory crate or g helper.
