I've recently installed debian 12 on my HP laptop. The installer automatically transferred my WiFi network information to the installed OS after finishing, and since then I never touched anything related to wifi. Now that I'm out of home, I wanted to connect to another WiFi, but I wasnt able to.
First, nmtui didnt show anythining related to wifi. I had to modify the file /etc/NewtorkManager/NetworkManager.conf and modify the managed parameter to true.
After that, I stll wasnt anble to see wifi connections, but at least nmcli didnt show both the ethernet and wifi asunmanaged, and instead showed them as unavailable.
After looking a bit, I discovered this:I looked up a bit more and found that running this:fixes my issue, as long as I keep my laptop on.
I've looked up a bit more, and in theory there must be a confict with two network managers, but the thing is that I havent installed nothing network-related, and i dont know how to identify wich are the managers that are in conflict
