Finally decided to convert to the penguin. I have live booted mint from a usb, without installing it yet, on a macbook pro 2017. But none of the WiFi networks in my apartment are showing, except for a few weak ones. Help a newbie out :)
Edit: To clarify it is not installed yet. Just used it from a live usb.
Edit 2: Used phone as tether for internet and went through all managers. But none had any updates that worked. I also tried installing b43 and after that wl. But both did nothing on the live usb boot, I assume since modprobe doesn't do anything on a live boot. But I ain't installing if it won't even work on the live boot.
Have you by any chance configured the wifi channels on your router/AP by hand? I had a problem a long time ago, where some device would assume it's in the US, while the AP was set to another country code and you could choose wifi channels that in the US are verboten.
