After updating and rebooting my laptop, I seem to have lost my wifi device. Since it still is physically intact (everything works when I boot a live system from USB) I have the suspicion that something went wrong on the CentOS side. Also, ,my password prompt after booting (system is encrypted) now appears to see an US keyboard layout, instead of the German layout it should have, so it seems like there is indeed something wrong/changed with my system.

Apparently there used to be some issues with older versions where the system simply forgot the "NetworkManager-wifi " package, but according to "rpm -q" I still have that.

"rfkill list" does not list my wifi card, whereas "lspci | grep Network" seems OK: "04:00.0 Network controller: Intel Corporation Wireless 7265 (rev 59)"

So, is it "simply" an issue with with CentOS, or did I do something wrong without realizing it?
