British regulatory authority Ofcom said on Wednesday that people should avoid using the microwave while making video calls, watching HD videos or other online activities. That's because, according to Ofcom, ovens can interfere with Wi-Fi signals around the house.
The tip was included in advice on how to improve broadband performance during the coronavirus pandemic, after the demand for networks has increased as millions of people work and learn at home.

Ofcom also said that cordless phones, baby monitors, halogen lamps, dimming switches, stereos and computer speakers and TVs and monitors can also affect Wi-Fi signals if they are too close to the routers .
Ofcom chief executive Melanie Dawes said that families across the country were accessing the internet at the same time this week, often to work and keep children busy.
"We encourage people to read our advice on how to get the most out of their broadband, home phones and cell phones and share them with friends, family and colleagues, to help them stay connected as well," she said.
Ofcom said that landline or Internet calls can offer a more reliable connection than mobile calls during the day, due to increased traffic on wireless networks.
