I found this on the internet: https://www.intel.com/content/dam/www/public/us/en/documents/white- papers/usb3-frequency-interference-paper.pdf When I pinged my router, I've seen some packets had a greater latency then others, so that could have been an interference. I couldn't test 5GHz as I don't have 5GHz with my router. I can't mesure voltage as I can't find vcgencmd for ubuntu.
