Thanks All for your great help. I am also affected by this issue with my Dell 5420 equipped with a I219-LM card (just arrived home yesterday).
I came across the AskUbuntu thread from Dell Community forums: https://www.dell.com/community/Latitude/Dell-latitude-5420-5520-intel-ethernet-on-ubuntu-20-04/m-p/7889980 After the "sudo ethtool -C xxxx rx-usecs 6000" command I keep seeing rx_errors and rx_crc_errors with: sudo ethtool -S <device> | grep -i err Do you know why?
