WiFi is the best connection at my house for most things. I have it first in network preferences under
However, I have a NAS connected over a local switch which I want to connect to via Ethernet.
The route is such that if I use WiFi, I reach the NAS via Powerline which dramatically slows the link.
When I disable WiFi I can connect to the NAS nice and quickly over Ethernet. If I do this, then all my other network connections go over Powerline and they are bad.
Question: How do I have both adapters enabled, prioritising WiFi, but utilising Ethernet for my NAS connection?
Note: I have tested and OSX does not find the local switch's Ethernet route with both adapters enabled and WiFi prioritised. It dumbly uses whatever is in the service order, whether it's Ethernet or WiFi. I had hoped it would choose the best route.
