It seems something went wrong after the latest update with AppleBCM5701Ethernet.kext Version 10.3.1

How do I correct this?

Ethernet not working even though it says "Connected" I've tried to troubleshoot my Ethernet connection with information from other sources but have had no success. In my case, when connecting my Mac (macOS Ventura 13.1) and going to Network settings I have seen the following settings in different occasions (images attached). As seen there, the Router setting is always empty. The adapter and cable are good as I've tried them in a different place and work fine. What can I do to trouble shoot this? Thanks!

Ethernet not working on IMAC after power outage What could be wrong? I performed apple diagnostics and everything showed up okay. Ethernet port does not work when connected directly into the computer, only works with a dongle.

Why does Mac Studio have Ethernet connection problems? I have tried two refurbished mac studios, and both suffered from Ethernet "exhaustion" syndrome, where the Ethernet connection works fine for hours or days, but then freezes. Since apple support had no clue (despite numerous complaints from others), I researched the issue and applied all suggestions (set for 1gb, disabled tracking protection AND updating to latest OS version), but it still occurred (all my other pc's maintained connection). I used ping software diagnostics, and it does not appear to be a hardware issue (I reached the router with no issue), so this should be solvable. In the end, I had to return the machines as a top end computer should not require hard rebooting to establish network connections .... which can then fail at any time, as with downloading.

Safe Boot, (holding Shift key down at startup), does the problem occur in Safe Mode? Could take 10 minutes.

Safe mode attempts to repair Disks & clears lots of caches & loads safe Drivers, & prevents loading of 3rd party extensions, so if Safe Mode works try again in regular boot.

To find out if it's system wide or user specific, try this...

Open System Preferences>Users & Groups, unlock the lock, click on the little plus icon, make a new admin account, log out & into the new account.

Does it work in the new account?
