Second ethernet port missing

From a couple of weeks I have had two ethernet ports on my ubuntu 22.04; one was integrated and the other one was just added with a board on the PCI bus.

They was named enp3s0 and enp4s0

Today the new one stopped working.

"stopped" means that is totally undetected.

This happened right after a reboot to force an update, so I guess it is due to a bug.

The system log says

I think it is matter of the name: one is "RTL8168g" and the other is "RTL8168d".

Anybody has the same issue, or can suggest me something?

Thanks

Why do you say "undetected" ? Update the question with the command and output why you say "undetected".

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
