Does changing Logic Board also change WiFi MAC address?
I was under the impression that the WiFi MAC address is stored in firmware on the computer. Recently I brought in the computer for logic board replacement and after one attempt to avoid the repair, Apple finally 'replaced' it, but my WiFi worked right away, with the same MAC address (wouldn't have worked otherwise). So, can the logic board be replaced while still maintaining the MAC address for the WiFi?

@dan i have run into a similar issue with my mid 2017 iMac. When I replaced the logic board in it i used the preexisting AirPort card, and wifi is working but Ethernet port does not seem to connect. I have done nvram reset, SMC reset, switched ethernet cables, deleted and added the Ethernet network, reinstalled macos. Currently, i am using macos Catalina on a 2017 iMac 20.5" (EMC 3069). Is there a way to resolve the issue and make the Ethernet cable to connect?
