Is the Wifi module working?

iwconfig

My terminal answers: unknown command.

Why is that?

I don't have my pine64 running at the moment (card is currently re-imaging) so I can't verify the permissions but try running iwconfig as root (sudo iwconfig) and see if it works then. Otherwise, it is missing, and you'll need to run sudo apt-get install wireless-tools to install the missing bits. The same is probably the case for ifconfig as well (although I don't remember needing to use sudo - but it becomes second nature after a while when a command that should work doesn't) - you generally need root privileges (sudo) to make any system configuration changes. Hence since most of the command listed earlier need sudo, you use sudo -i to enter the root environment and stay there until you exit it, so you don't have to keep adding sudo to every command.
