The model i have doesn't support wifi (don't have the wifi adapter) as it's the non-W model.
I managed to once do tethering with a usb cable, but I forgot how i did it (it was a while ago and i never took notes)
How can i connect my rpi0 to internet by using a usb cable (one connected to the rpi0, the other end to a computer which is already connected to internet)?
I don't want to have to buy anything to achieve this. I'm also well aware of the slow speed that USB would give for an internet connection.
PS: I'm using Linux on the computer i mentioned in my example.
