Thank you!
This is the end of the story.
I ended up moving in with family and they had internet access.
I didn't use a Pringles can, because, at that time, I didn't know about that method.
Instead, I twist-tied the adapter to the center of a big metal strainer that fits over a large frying pan.
This thing came in handy even after I had internet access, so, I continued to use it to boost the signal coming from the router.
