So I installed fedora 31 KDE on an external ssd. It’s working good, but I have a problem.
For some odd reason, on the macbook that i plugged the ssd into, there was no internet when using fedora.
I also noticed this issue when trying out elementary OS.
Does anyone know why this might be?
Thanks in advance. 
Can you specify what Wireless card it is?
(lspci -v, search for Wireless or a such; post “Kernel driver*” lines too, please).
i believe it is the broadcam bcm4331.
Probably you can find the required stuff in a package coming from the rpmfusion repository.
To keep it simple, you should connect the computer using a wired connection, then install the rpmfusion free and non-fre repositories and then the broadcom-wl package. (Maybe).
I will try that, thank you so much!
