LAN Card that works with MacOS

Hello,
I have a problem. I installed MacOS Sierra on my PC but everything works.
The network card does not work I have looked in the forum but for 10.12 nothing
I want to buy a new network card but I do not know which one. I would like it to be compatible with 10.12 without installing kext

Thank you
