I have installed Ubuntu 16.04.3 LTS Desktop (64-bit) on an external hard disk. I want to be able to use (plug and boot) this disk as a "Linux PC" on various hardware.
It boots fine both on my old iMac 7,1 and my MacBook Pro 12,1, but I have some WiFi problems.
In order to make the WiFi work on my iMac, I need to have
bcmwl-kernel-source installed. But this way the WiFi won't work when I boot on the MacBook Pro.
In order to make the WiFi work on the MacBook Pro, I have to copy the firmware file
/lib/firmware/brcm and delete the
bcmwl-kernel-source. If I don't delete the
bcmwl-kernel-source this solution won't work. But if I delete the
bcmwl-kernel-source the WiFi won't work on the iMac.
Is there any way to make the WiFi function on both machines?
