I use Ethernet cable to the network, that is not have internet connection. I use it only to wake on Lan and remote control my pc and I use wifi connection to connect to internet.
In osmc network settings I see only one “wait for connection” button to all of networks and when I power on my raspberry pi 3b+, wifi is not connect (except when I pull out the utp cable before power on it or I connect to my network manually in the osmc network settings.
Can I change this settings somehow?
IIRC, you can edit /etc/connman.conf and set:
PreferredTechnologies=wifi,ethernet
