Extremely rare wifi problem

[badlalo]

I have tried absolutely everything yet the same problem persists with different distros (for expample: Ubuntu 20.04, debian 11, ubuntu 21. I can't remember and finally the distro I've decided to stay with is Linux Mint 20.2 Cinnamon)

The error is my Wifi, it is enabled, all drivers are up to date (Broadcom b43) ethernet connection works just fine but no wifi networks are displayed.
I've tried everything and im a big noob to Linux in general (that's why I decided to install and learn) but it bugs me that I cannot connect to a wireless network. Any help or suggestions is greatly appreciated and I can provide any info needed

I did those commands and after the first one i typed my password and nothing happened, after that I typed the other commands and rebooted and did the last command and this came up

Did exactly as you said, this shows up.

[sleeper12]

Do you have Windows on that machine or Mint only?

[blueicetwice]

Badlalo, I would try installing the Kernel 5.11.0.38 or an old Kernel than you are presently using.
This can be done via the update manager.

Good Luck.

EDIT: Check out this thread. The second post from the bottom maybe your answer.
