Why can't my Mac Studio connect to the internet via Ethernet?

Launch a browser and enter this easy to remember all-numeric IP address:

1.1.1.1 

in the address bar,  and press return.

If you get the CloudFlare** splash page, your internet is working, but DNS lookup may not be working.

**CloudFlare is NOT part of the solution, they just own the easiest to remember all-numeric IP Address.

The Mac Studio M4 Max only supports Ethernet connections at least 1 Gigabit speeds. This requires cables with all eight conductors in the cables, and wired properly. Four-conductor ethernet cables are useless, and any Router or Switch you connect to DIRECTLY must be Gigabit Ethernet capable.

That said, I would not expect to see status 'Connected' if these were defective. Do you also have a valid local IP address, and a Router IP address showing in the Ethernet status pane?

How were the files transferred from old to new Mac? Using Migration Assistant after the macOS install, or transferred using Setup Assistant during the install, or transferred manually or using some other means?

Can you connect via Wi-Fi? (Or is wired your only available path?)
