Wi-Fi and Microwaves both operate on a similar frequency, which can lead to interference.
And if thats the case why doesnt Wi-Fi cook you?
The ITM designated the 2.4 GHz band as an unlicensed spectrum specificallyfor microwave ovens.
All this lowered the cost and barrier of entry for consumers.
However, a microwave is powerful enough to overwhelm any nearby Wi-Fi signals.
Microwaves have shielding to prevent this, but they aren’t a perfect Faraday cage.
The very nature of a mesh window on the door prevents that.
If it can leak solids, then it can leak radio waves too.
Microwaves and Wi-Fi devices use a similar enough frequency that one can interfere with the other.
A Wi-Fi router sends its signal out omnidirectionally.
That is, it sends it in every direction in a rough circle as far as it can.
That’s why microwaves have spinning plates.
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.
Wi-Fi is much more sensitive, and it doesn’t take much to cause an issue.
Instead of replacing the microwave you could move it.
Alternatively, buy a new Wi-Fi router that operates on the 5ghz band.
You will not only avoid interference from the microwave, but you’ll also prevent interference from your neighbors.
