That lacks important information:
USB 3.x interference with 2.4GHz is local to the USB port. It is not a problem farther than a few inches with USB 2.x using 2.4GHz peripherals.
It is mitigated by as little as 2", or less, using anything to just get it away from the 3.x port.
Just a clarification that USB 3.x is not going to affect WiFi.
Yeah, this is a 2 year old post/thread but you bumped it. This post is more up-to-date.
