Poorly shielded USB 3.0 cables and USB 3.0 devices can interfere with wireless devices.

see > Resolve Wi-Fi and Bluetooth issues caused by wireless interference - Apple Support

In this case, moving the USB 3.0 cables and devices away from your wireless keyboard, mouse and/or trackpad may help clear up the problem. If not, then you may need replace those thin poorly shielded cables with better cables.
