Hello Haines,

I certainly am no expert on this, but I'll try to help.

I think so. That's what you suggested in the first place and what I proposed.

I think, you are on the right track here. Check how your interfaces are named
with

ip addr

or

sudo ifconfig

and change /etc/network/interfaces accordingly.
