Thunderbolt Ethernet has a self-assigned IP address and will not be able to connect to the internet.
I've been successfully connecting to ethernet via a powerline adaptor (home plug) in my studio. The ethernet cable directly connects from a powerline adaptor to ethernet port on my MacBook Pro. and I was able to switch from wifi to ethernet easily.
I then tried connecting to ethernet via Belkin Thunderbolt Express Dock. Now ethernet has an orange indicator in 'network' and displays message that 'ethernet has self-assigned IP address and will not be able to connect to the internet'.
I tried to go back to directly connecting the ethernet cable into the ethernet port on MBP, but now I get the same message ''ethernet has self-assigned IP address and will not be able to connect to the internet'. I've tried to renew DHCP lease, but to no avail. Is this something to do with internet sharing? Please someone explain.
