Hi all,

I installed GhostBSD on my old 2007 MacBook, but it seems that the Wi-Fi wasn't installed. I managed to get it to show up in the network manager in the GUI, but clicking enable doesn't seem to do anything. Did I miss something in a config file somewhere?

Search here please:

There are a lot of drivers of Broadcom.
It could be the kernel module: boot/kernel/if_bwi.ko you are looking for.
