Windows using 1Gb connection instead of 10Gb

[IzzyMC]

So I currently have my Windows PC connected to a Linux tower running RAIDZ, both via 1Gb LAN and a 10Gb Mellanox SFP+ connection.

For months I was getting 500MB+ speeds to and from my NAS via the 10Gb, but this was before I bought a splitter and connected my NAS to the 1Gb as well.

At some point after adding the 1Gb connection, Windows started using it instead of the 10Gb. If I unplug the LAN cable Windows can't connect to the NAS. But using PuTTy I can ping the IP just fine.

Unfortunately the NAS was built and set up by a friend of mine who isn't available to help. My knowledge of these systems is limited, so any help you can offer is greatly appreciated.

Thanks!

Why a splitter ?
What make and model ?

Whoops, meant 'switch'. I'm using the "NETGEAR 5-Port Gigabit Ethernet Unmanaged Switch"

I got it so I could share my ethernet cable with both my PC and my NAS

What version of windows ?

Can you draw up a diagram of the physical connections ?

What is win showing for available networks and devices on each ?

It sounds like windows thinks you have two network connections and switched which one it is connecting on.
