I'm a bit of a tech novice so please bear with me. I have a DHD and a WiFi router to which is connected a network media drive. What do I need to do to connect my DHD to the home network so I can exchange files with my network drive without involving my computer? Do I need to set up a VPN? If so the phone's asking for a load of data I just don't understand. Sorry if this is absurdly basic and thanks for your time.
