This is a new computer. A couple of days ago while briefly trying Ubuntu via USB drive, I managed to get a wired connection to work, however today I installed Ubuntu with the same USB drive and configured a wired profile via the network manager GUI (top right corner of the screen) in the same way as two days ago, but the wired network is not configured properly.
I defined the address, subnet mask, gateway address and DNS servers (as I have done previously), but the network icon shows a ? sign and does not connect to the internet.
When I try to ping one of the DNS servers I get ... icmp_seq=3 Destination Host Unreachable
When I run nmcli device status after disconnecting wifi I get:
DEVICE TYPE STATE CONNECTION enp4s0
ethernet connected newWired lo loopback connected (externally) lo wlo1 wifi
unavailable -- p2p-dev-wlo1 wifi-p2p unavailable --
The results of sudo lshw -C network are (details about the wireless network that is working fine):

I have tried to provide the information that I thought was relevant, but I admit my ignorance in this. If there is any other information that is relevant, please ask.
I have been researching this for a while, but that only made me painfully aware of how little I know about this. As the computer is new, the Ethernet driver may be an issue although the particular device seems to have had a working Ubuntu driver since Ubuntu 22.04.2.
