Does microwave interfere with 2.4 GHz?
Some microwave radiation leaks out and interferes with WiFi signals, i.e. 2.4 GHz radio waves. Note that this interference at 2.4 GHz is caused by commonly used WiFi devices (e.g., WiFi routers, smartphones, cordless telephones, Bluetooth devices, and so on) that work on 802.11a and 802.11g standards.
Do microwaves use the same frequency as WiFi?
(1) Your microwave oven does, indeed, transmit radio waves in the same frequency range as WiFi (2.4GHz). But much higher power (most are rated 700–1000 watts, whereas WiFi is limited by law to 0.5 watts).
Why does my WiFi not work when the microwave is on?
Getting back to why microwave ovens can interfere with WiFi — to heat up food, microwave ovens pump out about 1,000 watts. That’s about 10,000 times more than a WiFi access point. By the way, many other devices also use the 2.45 gigahertz frequency band, which is what WiFi networks use.
Do microwaves affect 5GHz WiFi?
It’s worth pointing out, though, that the microwave interference only affects the 2.4GHz wireless band, so it can be avoided if your router supports the 5GHz band.
Why are microwaves used for WiFi?
Microwaves are used in microwave ovens, Bluetooth, Wi-Fi, your cell phone’s 4G or 5G connection, and lots of other wireless data transmissions. Their higher energy, shorter wavelength, and other properties make them better for high-bandwidth transfers than traditional, lower-powered radio waves.
What frequency do microwaves operate at?
about 2.45 GHz
Following international conventions, microwave ovens at home or in restaurants operate at frequencies of about 2.45 GHz, i.e. λ = 12. 23 cm. Figure 1 depicts a typical microwave oven (many details can be found in [1–3]). Microwaves are generated in a magnetron which feeds via a waveguide into the cooking chamber.

What frequency does a microwave oven operate on?
Why does my microwave not work with my WiFi modem?
Well, the reason for this problem is the frequency of operation, which overlaps between your WiFi modem and the microwave oven. Both usually operate at a frequency of about 2.4 GHz. However, unlike WiFi modems, microwave ovens do not transmit data, but emit signals in the unlicensed 2.4 GHz ISM band (Industrial, Scientific and Medical band).
Do microwaves use more electricity than Wi-Fi routers?
Microwaves also use more power than a Wi-Fi router; typically they generate 1000 watts of power. Conversely, a standard Wi-Fi router generates about 100 milliwatts (or 0.1 watts) of power. You’d have to increase the Wi-Fi router’s power output about 10,000 times and confine the beam to have a chance at cooking anything.
What is the frequency range of a microwave oven?
Both usually operate at a frequency of about 2.4 GHz. However, unlike WiFi modems, microwave ovens do not transmit data, but emit signals in the unlicensed 2.4 GHz ISM band (Industrial, Scientific and Medical band).
How to minimize Wi-Fi interference with microwave?
Another way to minimize interference is to keep the microwave a few meters away from the router. Since water is also a good absorber of electromagnetic waves, if you have a fish tank, it should also be kept a few meters away from the router.
