The Office of Communications (Ofcom) has compiled a list of tips to maximize internet  speed, including avoiding the use of microwave ovens.

With the UK government advising people to “stay at home” as offices, schools, and factories close down to stop the spread of the coronavirus, millions are now using the internet to work and keep themselves busy during the lockdown.

So media watchdog Ofcom has come up with a list of ways to maximize internet speed amidst the coronavirus lockdown, including avoiding the use of microwave ovens. This national information campaign is supported by the government and the telecoms industry.

Digital Secretary Oliver Dowden said: “Right now we need people to stay at home to protect the NHS and save lives. Reliable internet speeds will be crucial so we can work from home where possible, stay connected with our families and keep up to date with the latest health information.”

Ofcom said: “Did you know that microwave ovens can also reduce wi-fi signals? So don’t use the microwave when you’re making video calls, watching HD videos or doing something important online.”


The watchdog advised that internet routers be positioned as far as possible from other devices that may interfere with the signal, which include cordless phones, baby monitors, halogen lamps, dimmer switches, stereos and computer speakers, TVs and monitors.

With the increased demand on mobile networks, Ofcom is also asking people to make calls on a landline where possible. It mentioned: “If you do need to use your mobile, try using your settings to turn on wi-fi calling.”

“Similarly, you can make voice calls over the internet using apps like Facetime, Skype or WhatsApp,” it added.

Ofcom also advised users to disconnect devices that are not in use. It pointed out: “The more devices attached to your wi-fi, the lower the speed you get. Devices like tablets and smartphones often work in the background, so try switching wi-fi reception off on these when you’re not using them.”
