Broadcom Network controller

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.
