recently I have installed Mint 22.1 (first experience with Linux distribution) and as many users I am experiencing a problem with my Wifi Network (BCM43142,14e4:4365 rev 01), too. I am aware, that this is a common problem, I have read the articles here on the forum and did some research on the internet as well, but nothing helped till now. I would really appreciate it if you could help me, obviously there are different combinations/solutions for the same problem.
Here some information about my hardware:

about lspci -vvnn I get this:

About Capabilities and access denied: I have tried the steps from the following page: https://ubuntuforums.org/showthread.php?t=1990775 , unfortunately without any success.
I would be very glad if you could help me solve this. Thank you in advance.
Best regards
<access denied>that is just that access to some parts of PCI configuration space is restricted to root (seeman lspci), and doesn't explain the Wifi problem. If you runsudo lspci -vvnnthat will list the PCI capabilities, and an edit to include that information may help to get an answer.
