It's a bit weird question but here it goes.
I have a chromecast working a home perfectly. I would like to install Plex to stream my home videos. (haven't tried yet but I guess it should work easily as I have done it before playing a video in the chrome browser with vlc and streaming it).
However, I would like to know if I am gonna be able to do the same when I won't have my adsl connection. As Chromecast works through WIFI, I have to create some connection to make devices talk, but, does this connection need internet? I mean, can I create a ad-hoc wifi connection using a phone without sim (there is not internet) and connect a PC and the chromecast to it so I can stream from the PC?
Let's see if someone has tried something like this before.
