Based on some of the new reporting of possible Wi-Fi jammers being used, I think what you're seeing is them trying to either establish that one was used or rule out that fact.

Wi-Fi jammers work by overwhelming a signal.

You can think of it like sitting in a movie theater and someone screaming in your ear.

That's pretty much what they do.

They're going to flood the zone with signals.

Part of this requires a proximity to your device.

You can't block out everything from a distance.

A Wi-Fi jammer is a device you can buy off the internet.

They're illegal in the United States.

You can't possess them.

But if you do obtain one, they're relatively effective at stopping Wi-Fi signals.

They do this by just overwhelming the specific signal bandwidth.

How do you do that?

If you think of your wireless router,

It's got really two signals, 2.4 gigahertz and your 5 gigahertz signal band.

That's how it talks back and forth.

It sends and receives data.

Now, these jammers don't erase the signal.

But what they do is they emit such a loud signal that it's going to overwhelm your device.

Just like I said, going to a movie theater and having someone beside you screaming in your ear the whole time, you can't hear the movie, but the movie is still going on.
