If you’re having issues with your ethernet, chances are your ethernet chip is Realtek or Broadcom. They will both work on any Linux distros, however, for most distros you’ll probably have to find alternative drivers or even kernels. If you share the controller model here, maybe some of us can help you figure our the beat path forward.

You can try:

lspci -nnk | grep -A3 -i ethernet

That should bring up the information on the PCI Ethernet controller.
