Not sure there was anything you could have done differently, but there is plenty that you learned. Don’t give up, think of it like an extended interview process that you got further in, but didn’t work out. If you got one, you can get another. Next time ask for a setup with wifi, preferably a laptop. Most companies do laptops in my experience anyway. The fact that this last company insisted on wired AND blocked your travel router goes to show how incompetent they were. You might have dodged a bullet. If the next company insists on wired, now you can choose to explain your situation or jump straight to the private room for work.
Seconded obsidian + syncthing. My phone and my wife’s phone sync the obsidian notes folder to each other. We have shopping/grocery lists. So when one of us thinks of something we put it on the list, and when one of us goes to the store we have a combined list. It’s very nice.
