People should avoid using the microwave at the same time as their wi-fi, media regulator Ofcom has said, as part of advice to help improve internet speeds.
It comes as millions work remotely and rely on streaming services after the UK was told to “stay at home”.
This has put pressure on broadband providers, with BT’s Openreach reporting a 20% surge in internet use.
The government said reliable internet speeds were “crucial” as the UK battles the coronavirus.
Ofcom’s advice ranges from the seemingly obvious, like downloading films in advance rather than streaming them when someone else may be trying to make a video call, to the less expected.
“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.”
Position your internet router as far as possible from other devices that may interfere with the signal, such as on a table or shelf rather than the floor
Keep your router switched on
If you’re carrying out video calls or meetings, turning the video off and using audio will require much less of your internet connection
Try starting those calls at less common times, rather than on the hour or half hour
For the best broadband speeds, use an ethernet cable to connect your computer directly to your router rather than using wi-fi
Where possible, try not to use a telephone extension lead, as these can cause interference which could lower your speed.
Devices that can interfere with router signals include: cordless phones, baby monitors, halogen lamps, dimmer switches, stereos and computer speakers, TVs and monitors.
Ofcom also advised making calls on a landline where possible, citing an increase in the demand on mobile networks.
“If you do need to use your mobile, try using your settings to turn on wi-fi calling,” Ofcom said.
“Similarly, you can make voice calls over the internet using apps like Facetime, Skype or WhatsApp.”
The regulator also suggested disconnecting devices that were not in use.
“The more devices attached to your wi-fi, the lower the speed you get,” it said.
“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.”
