Since upgrading to Big Sur 11.1 my iMac says the "Ethernet has a self-assigned IP address and will not be able to connect to the Internet" message. I can only connect via Wi-Fi.
Have been unable to resolve...power cycled router, Time Capsule etc.etc.
Any suggestions or solution please?
I had the same problem some time ago. Called my cable company and they told me that resetting the router would do the job and it did. Not a power down but a reset of the router.
Hope this will help a bit.

If using Wifi, instead of joining your Network from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.

Again, thanks for the input but having tried three times am still getting Ethernet self assigned message......
Bizarrely the network settings page shows Ethernet Status = "Connected" while the "Ethernet has a self assigned IP address and will not be able to connect to the internet" message is shown just underneath.....??
Left side panel shows...
WiFi connection - Green
Ethernet Connection - Yellow/Orange
Bluetooth PAN - Red (but I am not trying to make this connection)
Thanks for the guidance, however did not work. Still have "Ethernet has a self assigned IP address and will not be able to connect to the internet"
Thanks but it did not work........think i'm stuck with just a wi-fi connection going forward......but cannot think of what else i might try...
