WD media player hub

I bought new WD media player hub. I am conneting external USB . I tried to play songs in folder and after each song it’s comes back to menu . How to play the whole folder ?

one more thing I tried copy the files to internal storage via eathernet and taking longer time to copy ( wired connection) . Is there a way to increase file transfer speed.

Thanks in advance

Press PLAY on the folder instead of OK.
