This is the Thunderbolt to Gigabit Ethernet adapter you are working with yes?
What is it being connected to? (Switch? Cable modem? Another computer?)
If it is a switch, are you sure there are no VLANs configured on the network? Or, inversely, are there any vlan interfaces on your Mac that uses the thunderbolt ethernet as its physical port?
Is it possible to manually assign a valid address for the network you are trying to connect to? That might let you connect (unless something like 802.1x is involved) and help troubleshoot.
Hi yes
I am using Thunderbolt to Gigabit Ethernet adapter
Connected to WAN of a TalkTalk Wifi Hub ( https://www.talktalk.co.uk/shop/wifiHub )
Only using the one Thunderbolt
I will try to manually assign an address then...
Thank you
Connected to WAN???
That’s wrong.
You need to connect to one of the LAN ports on the router.
Yes WAN
Sorry Duh.
Fixed (LAN) and working now Thank you.
