Hi all,

I am currently working on the remote communication on Balena Fin. I followed the instruction here: https://www.balena.io/docs/reference/OS/network/2.x/#cellular-modem-setup

I am wondering that once I plugging in a data card, how can I stop the WIFI connection, since Balena fin is currently communicated via WIFI? Should I just delete the WIFI information in system-connection file?

And is it possible by running both WIFI and cellular modem on Fin?

Hi

Seems like you are trying to do a couple of things together.

  • If you want to detect when a cellular modem is connected, I suggest you look into udev. Using udev rules, you can detect devices being connected, and then run scripts based on those events. So for example if you wanted to turn off wifi after a cellular device was connected.
  • You can turn off wifi on a device using the network manager CLI

A word of caution - messing up with something related to connectivity can result in making the device inaccessible. Please proceed with caution :slight_smile:
