I have an android media box which I used to connect to my desktop for watching media files stored in my desktop. I have used the TP-Link 500Mbps powerline adapter to connect with the media box. It was working well for couple of months but suddenly the connection is not working and says server not found. I even reset both the powerline adapters but still not able to connect with the desktop. I am however able to play media files through UPnP but it has limited resource as subtitles or audio tracks cannot be changed or included. The media box I have has both wifi and network connection and internet works fine with both network and wifi. I have also given sharing permission to all drives and folders which has the media file. Any help is appreciated. Thanks.
