The UK Office of Communications, that country's communications regulator, has promulgated the following to help to eliminate the slowing down of broadband speeds.
"Did you know that microwave ovens can also reduce wi-fi signals?" Ofcom asks.
"So don't use the microwave when you're making video calls, watching HD videos or doing something important online."
It suggests positioning your internet router as far as possible from other devices that may interfere with the signal.
Those devices include: cordless phones, baby monitors, halogen lamps, dimmer switches, stereos and computer speakers, TVs and monitors.
