I have just installed Ubuntu 20.04 on a new PC. The motherboard is an ASUS TUF B550
The ethernet cable is not working (i.e. when I plug it in, I don't get internet access), though when I plug it in I see a solid orange light, and a green light flashing, next to the port.
The cable works in another machine.
lshw I see this:

The USB device is a USB wifi adapter that I can currently using to type this. But it is very slow.
The Ethernet controller, by vendor Realtek has network UNCLAIMED next to it, which looks suspicious.
Could the UNCLAIMED device be related to my network cable problem? If so, how can I fix it?
