WiFi is slow when you use a USB 3.0 device

USB 3.0 devices emit radio signals that interfere with 2.4GHz WiFi. Switch to 5GHz WiFi to completely avoid the interference. This is temporary and not dangerous.

USB 3.0 external drives emit electromagnetic radiation that interferes with 2.4GHz WiFi during data transfer. The interference only happens while transferring data, not just when plugged in. Switching to 5GHz completely avoids the problem.
