Monterey 12.1 Missed Ethernet Interface

After update from 12.0.1 to 12.1 in a MacMini , the Ethernet interface doesn't appear in Network

I only connect over wifi , but can't connect wired


I tried to recreate the interface in the menu Network but the behavior doesn't make the interface appear



Mac mini, macOS 11.6

Problem solved.

After the upgrade to 12.1 , the aggregated link that stopped working and and the interfaces individually disappeared

The solution found was to delete the aggregated link and so the ethernet interfaces reappeared.

Now I'm using only one of the interfaces, from the MacMini itself


Tks for your attention !
