Which Microwave Does Not Interfere With WiFi?

Microwaves are an everyday cooking necessity for many of us because they are a daily-use appliance.

Likewise, going without the internet is unthinkable. It becomes much more troubling when the activities of one clash with those of the other.

What I’m trying to get at is how microwaves interfere with WiFi. If you’ve been experiencing intermittent WiFi connectivity and don’t know what’s causing it, blame your microwave.

This has probably made microwave users start researching microwaves that won’t ruin their WiFi connection. And that’s exactly what this article is going to guide you with.

There are no microwaves in particular that don’t interfere with Wi-Fi. Various factors may cause interference between microwaves and Wi-Fi.

It’s essential to check these things when attempting to limit the effects of the microwave on the WiFi. Especially checking the microwave’s leakage is key.

Another key issue is the power frequency the microwave and WiFi send out, in this case, the 2.4GHz frequency.

To avoid the frequency causing the interference, the WiFi needs to be set to the 5GHz frequency.

Not to mention the distance between the two devices; the closer they are to each other, the higher the chance they will interfere.

If you’ve not noticed the interference of the microwaves with your WiFi, check how well you can surf the internet on either your smartphone or laptop when the microwave is running and when it’s not.

Do all microwaves interfere with WiFi?

All microwaves, regardless of their wattage, emit electromagnetic radiation. The idea is that these emissions should stay inside the microwave, and the design allows for this.

This electromagnetic radiation finds its way out of the microwave when there’s leakage in the microwave.

These leaked electromagnetic radiations of the microwave tend to collide with the radio frequency of the WiFi. This then causes interference in the WiFi signals.

In that case, it is hard for electromagnetic radiation to interfere with the WiFi signal when the microwave emits no leakage on the side.

In other words, does this mean the microwave will only interfere with WiFi when there is microwave leakage?

No. The proximity of the WiFi to a microwave can cause interference with the WiFi signal, even without any leaks in the microwave.

When microwave and WiFi routers are nearby, there can be interference with the WiFi signal, even when there are no leaks in the microwave.

To answer the question: microwave signals are unlikely to interfere with Wi-Fi when the microwave and Wi-Fi router are some distance apart, and there are no leaks in the microwave.

How do I stop my microwave from interfering with WiFi?

If you have an older microwave model, chances are good that it could interfere with your WiFi signal.

Even with that, there are times; an obvious solution will be staring you right in the face, so check your options before you rush out and buy a new microwave.

So before deciding to replace your microwave, you can try these solutions to lessen interference with your Wi-Fi signal.

  • Upgrading your WiFi router
  • Moving WiFi router far away from microwave
  • Shielding your microwave

Upgrade your WiFi router

To completely get away from any kind of interference caused by the microwave, you should upgrade your WiFi router from 2.4GHz to a WiFi band of 5GHz.

Upgrading your WiFi router to a 5GHz band has its own set of issues – it is pricey, and its installation is time-consuming.

That said, it is worth it – you will have a smoother and much less congested time with the internet, and your WiFi won’t ever encounter interference.

Moving WiFi router far away from microwave

This will save you the hassle of purchasing a new microwave or upgrading your WiFi router by simply moving your internet router to the farthest place or position. The two devices should be at least 10 feet apart.

A WiFi range extender can help boost your WiFi signal at any distance, with a greater range creating a higher chance of not being interfered with the microwave radiations.

Moving your WiFi router to a room as far away from the microwave as possible would be better.

Shielding your microwave

Another proven way to prevent the microwave from interfering with the WiFi signal is installing a shield.

The shield will encircle the microwave and block the microwave frequency from getting in the way of the router.

One material that does an excellent job at blocking microwaves is aluminum foil.

A few sheets of aluminum foil can act as a barrier and prevent all microwave radiation from passing through.

How far should the router be from the microwave?

As we’ve come to know, one of the key factors to successfully using your microwave and wireless router is keeping them far enough apart that they won’t interfere with each other. But how far should the two devices be from each other?

The answer depends on several factors, including which model of router you use and the brand of microwave you own.

How far should the router be from the microwave?
How far should the router be from the microwave?

Suppose the router is positioned at the right distance from the microwave. In that case, it will help avoid potential interference so that your wireless router and microwave can peacefully coexist in your home.

Irrespective of the watts of the microwave, placing the WiFi router at a distance of at least 10 feet away from it will be okay to avoid interference with the WiFi signals.

Various experiments have been conducted with the microwave leakage detector device to find out the farthest a microwave’s radiations can reach, even if there is leakage in the microwave.

From all the experiments, at a distance of 8 feet, the device can’t detect any microwave radiation.

How can I tell if my microwave is leaking radiation?

The tricky thing about detecting a microwave leak is that microwaves cannot be seen, felt, or smelled.

The only way to tell if a microwave is leaking radiation is to use a radiation-detecting device.

If you’re worried about radiation leakage from your microwave, there are a few detectors you can use to check.

First, get an EMF meter; they’re inexpensive and easy to use. Then all you have to do is turn on your microwave, stand two feet away, and point your meter at it.

You should replace your microwave immediately if you see anything over 0.1 volts.

EMF stands for Electromagnetic field. The EMF meter is a device that measures electromagnetic frequencies (EMFs).

It can be used to test for radio frequency and magnetic fields. It can measure the levels of electromagnetic radiation that come from welding equipment, microwaves, and the surrounding environment.

Can microwaves interfere with TV?

If you’ve ever wondered if the microwave can interfere with the TV, yes, it can, but fortunately not to the extent that it can cause any damage to your television.

It rather interferes with the reception of your TV. You might not think that your microwave oven could be interfering with your television, but the truth is, they can, and they do, if the right measures are not put in place.

The interference caused between the microwave and television is not always that much due to the difference in the radio wavelengths of both devices.

Microwaves have a radio frequency band between 2 and 3 GHz, while televisions have a radio frequency band between 100 and 900 MHz.

Due to the differences in both devices will be minimal, even if there should be interference.

Having said that, if there are measures to put in place to stop the little interference, you should do.

You must ensure the microwave is a certain distance from your TV. I suggest a minimum of 10 feet, but the more distance, the better.

Whenever you turn on the television, ensure the microwave is turned off to avoid the emission of electromagnetic waves.


Unfortunately, unless your router’s WiFi frequency is increased to 5GHz, it is likely to suffer from the microwave interfering with its WiFi signals.

A 2.4GHz WiFi router and a microwave emit the same frequencies, just that the microwave’s wattage is higher than the WiFi.

This often makes the microwave overpower the WiFi frequency whenever there is a clash, leading to signal interference in the WiFi.

However, some preventative measures can be taken, as outlined in the previous paragraph, to lower the likelihood of interference.
