use wired ethernet before wifi ethernet

My Pi has a hardwired Ethernet connection as well as Wifi … when I do an update of my music (Music sits on NAS), it appears like the Volumio uses the Wifi link over the Wired Ethernet. It just takes a heck of a lot longer reading the file system over Wifi …

How do I ‘force’ the Pi to use the hardwire Ethernet before the Wifi Ethernet?


Turn off wireless.
But why would you do that?
Volumio performs good at wireless, same as on wired.
