Hello,
well, today I had a surprise - my WiFi on my Lenovo X1 Carbon (6th generation) was not working anymore. Yesterday everything was fine. Whereas today the network manager (Debian Buster with Cinnamon) does not even show me the WiFi device.
After checking several internet pages, which did not help, here is the first good hint I found:
sudo dmesg | egrep 'wl|b43|brcm|ssb|firmware'

Searching for this error message did also not provide me any help...
Can anybody help me?
Of course, I am also happy with a link which will point me in the right direction.

Re: WiFi (iwlwifi) stopped working
Hi all,
thank you for your fast feedback - and the end of the story is... the next day WiFi was working as nothing has happened before.
nmcli dev status shows the WiFi device again:
mcli dev status
DEVICE TYPE STATE CONNECTION
enx00e04c682709 ethernet verbunden config DHCP
enp0s31f6 ethernet nicht verfügbar --
wlp4s0 wifi nicht verfügbar --
lo loopback nicht verwaltet --
It is not a dual boot system - Debian only - since many years
Of course it would be nice to know why but I am happy that I can continue using WiFi.

Re: WiFi (iwlwifi) stopped working
Possibly just a hardware glitch where the device didn't wake up from sleep mode?
