Following up on questions like this, this and this (as well as some others).
The problem is that after installing an update and rebooting, I am unable to connect to WiFi. In particular, running sudo lshw -c network shows, that wireless adapter and/or network port are unclaimed. The first time it happened, I followed the advices on other posts and that solved it. However, the problem is persistant and occurs every time I reboot after an update. Furthermore, I found out that the problem "fixes" itself when I restart my computer many times. Any ideas why this is happening and how to fix it? Many thanks in advance! :)
Details
I am running on 22.04.2-Ubuntu, kernel version 6.5.0-41-generic, dual boot with Windows 11. At the moment, everything works. Running sudo lshw -c network outputs:
