>without my consent?

consent isn't needed, given that broadcasting your SSID in the open clearly fails the "expectation of privacy" test.

Also from a practical angle, what exactly are you trying to prevent? That there's a wifi router at your house?

But most people don’t intentionally “broadcast their SSID in the open”. They just want to surf wirelessly in their homes with as little hassle as possible.

Until there’s technology that lets you do that easily I think this definitely violates privacy. Especially if unique information like MAC addresses is collect, and not only the Wi-Fi name.

I wonder how MAC addresses are treated under GDPR since e.g. IP addresses are considered personal information.

When a consumer can see their neighbors' networks' SSIDs being broadcast on their own pocket computer, but somehow doesn't think that anyone else can see their own network's SSID, then:

That's magical thinking.

Magical thinking is not a privacy problem. Magical thinking is a cognition problem.
