Smart TVs sending sensitive user data to Netflix and Facebook

Fun fact: If the signal is reasonably strong, Wi-Fi will sometimes still work even with the antenna disconnected.

If there is an unwanted and wide-open AP within range of an antenna-less smart TV, you have an unusual problem with countless fun and creative solutions.

I guess it's much less likely if the exposed antenna connector is properly terminated.

Or maybe grounding it? I bet if you mash a little ball of tinfoil into the connector, any residual chance of it working will evaporate.

Who knows? This could make a nice little experiment.

   1. Leave the antenna connected
   2. Unplug the antenna, leave the connector unterminated.
   3. Terminate the connector with ball of tinfoil.
   4. Use a proper impedance matched termination.
   5. Terminate with a proper impedance as close to the wifi chip as possible
   5./b Also cut the antenna trace on the PCB as close to the chip as possible
   Measure signal strength in all scenarios.
