How do you stop a microwave from interference with WiFi?

Fixing a microwave interference with your WiFi signal will include, moving your router so that there is a distance between the two devices, changing your WiFi frequency band from 2.5GHz to 5Ghz, deep cleaning your microwave, or replacing it entirely .

Your microwave uses 2.450Ghz to heat up food and your router uses 2.412 GHz to 2.472 GHz to transmit your data over WiFi. This is why some people with old or faulty microwaves experience a problem with their WiFi signal when they try to make popcorn.

Following international conventions, microwave ovens at home or in restaurants operate at frequencies of about 2.45 GHz , i.e. λ = 12.

The ITM designated the 2.4 GHz band as an unlicensed spectrum specifically for microwave ovens. This band has three compelling properties: It doesn’t require much power to broadcast, it’s easy to contain, and at relatively lower power it can heat food . All this lowered the cost and barrier of entry for consumers.11 Oca 2019
