How to make the default setting of Lite-On Ethernet off?

  • 772

I have a Realtek Internet stick that I did a lot of shenanigans to install, and it works really well. However, every time I reboot the computer, it automatically tries to connect the Lite-On Ethernet. It also seems to randomly try to turn Lite-On Ethernet back on, even when I manually turn it off. Of course, it can't connect because I don't have an ethernet cable plugged into my computer, so it constantly sends "Lite-On Ethernet connection failed" messages, and it's really annoying. Is there a way to make it turn off automatically?
