Has anyone ever come across a NAS device that can create its own wireless hotspot free from any router. I'd like to set up a NAS as a plex server in my van running from an inverter or the 12Vdc supply so that I can access my movie and tv content on my iPad/iPhone on the go without using my home plex server to save on data. I have no need for it to be connected online, just sit there hosting its own wifi network. Any help would be awesome, cheers.
