Wow, it sounds like your living in Colditz. Do you not get sufficient signal strength on your phone? Maybe you could hotspot your phone to push wifi to your laptop?

It’s also awful about the food situation. Trying to think of ways around it. Does Uber Eats not deliver or maybe get a pizza delivered from dominos? Are you allowed to leave? Homes I don’t believe can legally hold you. You are a free man/woman to come and go as you please! God bless your situation !!
