I downloaded the Fallout Pip-Boy companion app, thinking I could use it offline simply by using the local connection that goes between my wireless printer and my PC. I believe it is technically a Wi-Fi connection, albeit one without internet, I thought it ought to work.
However, when I connect my PC and phone to that network, and then start up Fallout 4, the app says "cannot scan for connections please ensure Wi-Fi connection" or something like that; I don't remember exact wording.
Is it just something I'm doing wrong, or is this actually not able to use a non-internet connection?
