How to setup without any wireless connection?
I read the wireless part and it didn’t work.
Wireless setup is part of Linux and the Distro, more specifically than it is MineOS.
If you’re using MineOS Turnkey, you’re using Debian, which means any Debian instructions for Debian Jessie will work.
Keep in mind, however, that MineOS is meant to be server-oriented–and wireless connections are not server-oriented. This means that MineOS Turnkey may not be the ideal starting point for getting wireless up.
If that’s the case, I recommend using a more mainstream distro (like Ubuntu Server, which has waaaay more documentation on getting wifi working). When wifi is working, you can get MineOS atop your installation using the instructions in the wiki.
