Here’s a picture showing what I mentioned in my previous posts:

To be honest, I’ve chosen to now connect via a wired network, as that’s a 1Gb/s network and much faster.

To test my theory, I went back to an older install from before I installed the b43 driver and only typed this into a shell:

sudo iwconfig wlp3s0 txpower 10dBm

And then I could connect fine as well.

So most probably, it's not even necessary to install the b43 driver. Which means that I actually only had to do what phpmaven did.

I checked by typing just iwconfig, and saw that the TX-Power is set to 31dBm by default. Setting the TX-Power to 10dBm is probably the only thing necessary.

Worked like a charm for me (MacBook pro 2017, Linux Mint 22.3). Thank you.
You need to run iwconfig first to get the actual device name.
