use wired ethernet before wifi ethernet

Hi,
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?

Thanks,
Craig

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