If it is leaking enough to effect wifi then you really should get a new unit if you could.
I wouldn't cover it in foil as that will block the air intakes from cooling the unit.

This microwave is a fairly recent new unit surrounded by all metal already
The only thing that's plastic is the control panel but I'd doubt they'd leave the area behind that unshielded
Language police sirens. Something can affect something else, or can have an effect on something. Otherwise, perfect comment!
Policing the police I suppose. "Effect" can actually be used as a verb, and it means "to bring about a result". So something could effect something else. It's still used incorrectly in the original comment, I just wanted to contribute a nitpick I thought you'd appreciate.
Yes! Thank you! But I find it so rare on the internet that "effects" must be a typo like 99% of the time (pulled it out my ass but yeah)
Close enough. It gets the message across.
What's the purpose for this? How often are you microwaving that you're concerned about interference? Have you actually noticed a measurable drop in speeds when microwaving?
OP wants to protect the microwave and the food therein from the wifi signal.
router: "I'm not locked in here with you. You're locked in here with ME"
Now that's big brain
My first thought is its not the microwave unless they're multitasking TV dinners and League of Legends a few times each evening.
I just got this hunch it's something like clogged channels or something, but OP thinks a microwave just sitting there is the issue. But that seems just as unusual.
Also microwaves are only 2.4ghz. Any modern device should have a strong 5ghz connection in what I assume is a cramped apartment.
5ghz also has less interference problems, but it’s not immune.
I used to have a Google speaker on top of the microwave and it sometimes lost signal for a bit while microwaving. But it picks right back up and normally you're not microwaving for extended periods so it would seem a waste of energy to try and prevent it.
Yeah mine does the same to my Bluetooth headphones if I'm near it, but for like the two minutes that I'm microwaving my lunch, who cares. I want to know what the hell OP is using their microwave so much for.
Important questions
Hasn't your device a housing of steel already? This is a stronger shield against interferences than your aluminium foil.
I mean don't see why not, but you need complete coverage around it, including underside.
You could also try switching to 5 GHz wifi if your walls allow it.
Switch to 5ghz WiFi, microwaves wreak havoc on 2.4ghz
It is unlikely to make much difference. How often are you microwaving food that a small bit of interference is worth the effort to do this?
Download a wifi analyzer app.
It'll let you know which channels your microwaves 2.4ghz occupies. Google how to change your wifi to 5 GHz from 2.4. if not supported, just make sure whatever channel 2.4 vhz you're on is nott the same as microwave
No. It looks too silly. Other than that, there's no problem.
However, if your micronuker is interfering that much, you should get a new one.
Couple things. As long as its grounded to the microwave ground then its fine (yes even inside). Ur microwave is probably just too close to the WiFi antenna tbh.
I suspect what's actually happening is the microwave transformer is leaking non microwave em radiation which is causing the interference (maybe via come capacitive coupling bs).
Either way I would test if a different microwave in the same location causes the same problems and if so its busted. If the WiFi antenna is near the microwave try moving it first.
Provided you do not block any of the functions of the microwave, Buttons, door operations and venting, you will be fine.
Short answer is "Yes but your mileage may vary".
Actually blocking microwaves effectively requires more than just a sheet of aluminum foil, but it's a start: https://haitmfg.com/microwave-shielding-materials/
No
How are you pronouncing that word? Asked the whole world except America at once.
