Not the wifi issue, the power grid. Some of the cheap LED string are only half wave rectifier and if somehow someone stings up hundred thousands all exactly the same way, that seems to result in drawing several amp of power for 1/60th of a second, no draw in the next 1/60th of a second, and back n forth. (1/50th in European countries I guess)
Could those be an issue? I doubt anyone saw this when the power grid was designed over 100 years ago.
