Use the settings as mentioned above but do use: IP 192.168.0.77 or even try IP 192.168.0.177
The IP must differ from all those in recent use by the Hub 3 DHCP server.
Well do we know the ethernet port work is one thing or bad cable
setup a fixed IP with the following
IP 192.168.0.77
subnet 255.255.255.0
gateway 192.168.0.1
DNS 194.168.4.100 and 194.168.8.100
do ping 192.168.0.1
"I've tried manually replicating the IP addresses from the wifi. Which gives me a green 'connected' light. But no actual connection"
Those settings are the same as yours, except the IP address. I've tried with your sugestion and get the same result
Edit: forgot to do the ping. Restarted to do so, and it's working (on the manually entered same IP as was allocated to my Windows laptop - I don't know if that's relevant will mess about with the address later)
