since yesterday I'm facing the problem that I can't use W-LAN or Bluetooth with my Laptop device. I was running several commands from other threads (see below), but none was helping. At the end I booted the system with a different Kernel I had installed and finally the W-LAN worked again.
Today, the yesterday's issue appeared again but this time I'm unable to figure out how to get along. Any help is appreciated.
Here, the error output looks similar to the one I've got, but execution of the commands rmmod and modprobe did not help.
This did not help either.

Following Pilot6 advice to install HWE it still does not work. However the error message is more precise this time:

sudo dmesg | grep iwlwifi outputs the same output as before.
Update 3
Following @unbi-rabka answer did not solve the problem.I still do not have wireless connection.
sudo dmesg | grep iwlwifi outputs:

Also I tried to install a brand-new installation of Ubuntu-18.04 alongside my current installation. But it did not help either.
