First, thanks for making my email publicly available to spam bots. I thought
there were private? At least I can't see the email addresses from other
people on this forum :P
I have not considered purchasing an external ethernet adapter because I have
read that other people ran into problems with this when running a linux
distro. Most of them were related to the thunderbolt/displayport however. So,
using a USB wireless adapter was my best choice and as it turns out I have a
free software compatible USB wireless adapter from TP-Link.
With the kind help of @lembas I have updated the libre-kernel to
linux-source-3.10.0-gnu but this did not solve or help with the problem. It
only added another noticable problem where my Macbook Air would not shut down
anymore :(
It's easy to blame some company, but I want to focus on finding a workable
solution. My next computer will be purchased with free software compability
in mind. But for now I want to get the dual boot working with the internal
hardware if possible - there are open source drivers for my wireless chip.
This is my first time using a FSF endorsed OS. I did not expect this to be
easy. But completely switching my workflow 100% after 7 years of using OSX is
quite demanding. The dual boot setup is my conversion phase. Hopefully, I
will get it all working so that I can make the full switch to libre software
in the future.
