I have an ethernet connection it’s connected DHCP, and also Wi-Fi. Wi-Fi every once in a while goes haywire, but the ethernet should be stable. Whenever I go to network preferences and connect to ethernet 2, everything looks fine but it still wants to prefer Wi-Fi and it just prefers the Wi-Fi connection. I also do use Wi-Fi to network printers, and with other workers who come over they want to use the Wi-Fi. But I’d rather on my Mac just have it use the ethernet, and it won’t let me. Or I simply don’t know how to do it. Any tips hints would be greatly appreciated. Thanks. When I turn Wi-Fi off lose Internet. I don’t get it. Or eventually reroutes but so slow.
