--- Comment #5 from Terry Barnaby <te...@beam.ltd.uk> --- Hi, The output of "nmcli -f all connection show" is given below, but this does not appear to have any information on the Ethernet physical link settings so I'm not sure what help that is ? Creating a new "Wired Ethernet" connection using plasma-nm appears to set the "Auto negotiation" on by default as it should. It seems as if plasma-nm fails in this re-guard if there is already a ifcfg-* file that does not have a "ETHTOOL_OPTS" entry.
