Here's proof how my tablet can connect to my PC (Kodi, UPnP source).
Then you can see how the Mibox can't connect to the same source with the same method, even though it did just 5 minutes ago.
Only after unplugging the Mibox (restarting Kodi changed nothing) did it detect my PC.
I just want to listen to music and watch a movie from beginning to end without losing connection every fucking day. Is that too much to ask for?!
I wish I were rich so I could afford a Shield
Try Kodi 18 alpha or SPMC (due to SMB1 issues and Windows 10 after Creators Update) and SMB source.
My Shield couldn't connect at all until after I changed to either Kodi 18 or SPMC
