Can you please try to Hibernate your laptop to disk, then start it again and test the LAN connection? On my Fujitsu S7311 with I219-LM with Ubuntu kernel 5.10.0-18-generic hibernating running OS to disk and then turning it on makes LAN working as expected without any error (no special kernel parameters). Very strange behaviour.
