Force LAN connection instead of Wifi

Hi I have kind of a unique network structure, with 5 computers each having wifi adapters to get internet but also networked with a LAN (ip range 10.0.0.101-105). This is because I can’t get a wired internet connection. In syncthing I am getting wifi speeds for transfers instead of gigabit LAN speeds. Is there a way to force LAN ethernet connections instead of wifi?

You can set allowed subnets per device in advanced config, to for example 10.0.0.0/8

You can set up IP addresses manually and use the LAN IP’s for setting up communication among servers…
