Block Wifi Signal intentionally


We are using a TX2 and we would like to block the wifi signal, we realized that even without attena the Tx2 is able to connect to the wifi router if it’s very close.

We don’t want to do it through software or DTB.
is there any external pin I can use to disable wifi?
What do you recommend for blocking the signal?
Do you think an RF terminator will block the wifi signal?

Hi, no such pin exposed. The wifi part is module inside, the enable pin or power supply can not be handled externally. You need to disable it through sw.

thank you for you answer

Do you think if we used and RF terminator this will not allow on the wifi connectors this will stop the wifi signal not allowing to connect to a router when is close

Not familiar with that, did you try shorting wifi antenna connector to GND on board?
