I have a balena fin v1.0 which used to run stretch. It used to perfectly show all available wifi (2.4G and 5G). However I was not able to have the same on the buster image when I got it back in 2020 so I reverted back to stretch. Now, stretch is depreciated with most of the packages and versions absent. I had to upgrade and I decided to install bullseye. Now I am facing the same issue in which wlan0 interface does not get detected. I don’t think it is a hw problem, but more of an interfacing or driver problem that exists in later version of rpi OS. Can someone guide me on how to replicate the wlan0 settings in stretch and manually copy them to the bullseye image?
