Btw… i just tried to copy a file to and from the Vero and i get 20mb/s now… i didn’t do anything other than disconnect/reconnect the hdd and restart the Vero 
more than this should be impossible with my connection, right?
only from my smartphone it’s still stuck at 2,90mb/s, but i can live with that 
and the backup all of a sudden also works, don’t know how or why but i’m glad
cheers
