I have bought the LEAP-S3+ TV Box 4K model. I want to use it as a media player, and I want to connect to my own internal Windows network shared resources as movies and pictures. I can connect to my router in the WiFi settings, bu I can not see any shared resources on my computer. I thought that was the main meaning with all media players, including this one. Whats wrong, do I need to install some app to make it work?
