No, Wi-Fi routers will not work if placed inside a microwave oven. In fact, putting any electronic device, including a Wi-Fi router, inside a microwave oven is a bad idea and can lead to various issues.
Microwave ovens are designed to emit electromagnetic radiation at a specific frequency to cook or heat food. The metal enclosure of the microwave oven acts as a Faraday cage, containing the electromagnetic radiation within it. This design prevents the microwaves from escaping and interfering with other electronic devices outside the oven.
When you place a Wi-Fi router inside a microwave oven, the microwave's metal enclosure will block the Wi-Fi signals from transmitting outside. This means that your Wi-Fi signal will be severely attenuated, and your devices will likely lose connectivity or experience a very weak signal, rendering the router practically useless.
Additionally, microwaves can generate electrical interference, which can disrupt the proper functioning of the router's components and circuitry.
It's important to keep microwave ovens and electronic devices well-separated to avoid any potential damage to the devices and to maintain proper functionality. Always place your Wi-Fi router in an open area, away from large metal objects or appliances that could interfere with the wireless signal. This will ensure the best Wi-Fi performance and coverage for your home or office.
