I'm sorry for the noobie question. I'm following the digital library tutorial from "https://learn.adafruit.com/digital-free-library". Currently I am using a Raspberry Pi Zero W and connecting through usb as an Ethernet connection. Whenever I change the settings in /etc/network/interfaces I stop being able to ssh through the wired connection. (https://learn.adafruit.com/digital-free-library/configure-access-point this step). Clearly I don't understand something here and could really use some advice about what's going on if possible?
Thank you for what assistance you can give me.
