USB 3.0 can disrupt nearby 2.4 GHz Wi-Fi and Bluetooth devices
Intel documented the interference mechanism in 2012, tracing it to broadband noise from some SuperSpeed devices, cables and connectors.
TLDR
Some USB 3.0 devices, cables and connectors can emit broadband noise that overlaps the 2.4 GHz radio band, reducing the range or throughput of nearby Wi-Fi, Bluetooth and wireless peripherals. Intel documented the effect in 2012 and measured a nearly 20 dB rise in the 2.4 GHz noise floor in one external-drive test. The problem depends on hardware, shielding and placement; moving a wireless dongle away from USB 3.0 equipment, changing ports or using a better-shielded cable can help.
