Macbook/Ethernet adapter/Hub 3 - No DHCP

[anthonyqkiernan]

I have an USB-C hub with ethernet.  I have keyboard, mouse, power (usb-c), hdmi and ethernet connected to it.  Plugged into my work laptop (Lenovo notepad) everything works straight off as expected.  When I plug it into my Macbook Air (M2 running Sonoma 14.1.2) I cannot connect to the ethernet.  Everything else works fine

When I go into the network settings I can see a self-assigned IP address.  Which I believe means something isn't working with the DCHP. 

The network light is on on the usb-hub.  Logging into the Hub 3 shows (I think) that it's connected too.   (The other device is NAS drive)

Any ideas how to get this working?

I've tried manually replicating the IP addresses from the wifi.  Which gives me a greent 'connected' light.  But no actual connection

That's what I'm using 😂

For anyone finding themselves here after the same journey of googling as myself.  Please note: The 'fix' above did not hold.  I cannot relicate it again.  I suspect there was some magic combination of plugging/unplugging and stopping/starting that I'm not getting right
