Hello Ivan and Nico,

thanks for your answers. That clarified a lot. I still have some questions:

To sum it up, I have 4 possibilities:
1. Live without ethernet firmware and without internet
2. Use the untrusted ethernet firmware with a small risk in terms of security/privacy
3. Don't use the ethernet firmware and only use a free miniPCIe Wifi card? Is this possible?
4. Don't use the ethernet firmware and only use a free USB Wifi stick

But than I can't disable Intel ME and can't use me_cleaner?
If I read correctly: when you disable Intel ME, you have to insert IFD and GbE into coreboot? Btw, do I also have to insert EC firmware than?
