How do you disable telemetry in a new car. I have a 2022 Kona. It's the first car I've had with telemetry. No idea how to disable it.
Find the cellular and/or wifi antennae and cut them.
I have a tesla wall charger. I never wanted to connect it to wifi, but it creates its own unique wifi access point TelsaWallConnector-blah-blah.
so I thought - I'll just disconnect the antenna!
nope, still shows up.
so... I'll just wire the antenna it to a dummy load!
nope, still shows up.
It appears the wifi chipset has an on-board antenna and an external antenna connector and it uses them both.
I suspect this stuff happens for wifi and cellular chips in lots of devices.
