I am working on iMac Retina 4K 2017 with macOS Big Sur v.11.2.1.

The Ethernet is connected to the iMac but unfortunately no internet access.

I've tried these approaches:

  1. I've created new location and add Ethernet with Configure IPv4 is Using DHCP.
  2. I've tried Renew DHCP Lease.
  3. I've tried to Configure IPv4 Manually and add Google DNS Server as my DNS Server.
  4. I've re-plugged in the ethernet cable.
  5. I've restart the iMac either before or after above configuration.
  6. I've unchecked all Proxies.
  7. Router has been restarted.
  8. Etc. (i don't remember the others).

All the above approaches doesn't work at all.

enter image description here

I plugged in my cable on Windows PC and it worked beautifully!

  But unfortunately doesn't works in this iMac.

this is the screenshot: my network setting.

We can see the ethernet indicator is green but no internet access.

How to solve this ? Anybody please help me.

By the way sorry for my bad english.
