Last night I was trying to make Dolphin show video thumbnails and it toke some Time but I managed to do it unfortunately when I restarted the laptop there was no wifi!
I did update the system (sudo yum update) and installed some packages for the ffmpeg but nothing more and now (network) service is down and can not be started
Also when I tried "nmtui" there was no wifi coeenction at all!
Here are some output for the commands I thought may help me understand
Code: Select all
# lspci -nnk | grep -i net -A2
