    Hi,

     

    I found the my 10G network card cannot negotiate to 5G link mode after system boot.

    However, the link speed could recover to 5000bastT/Full after executing command "ethtool -s eth0 autoneg on".

     

    My network card is "Intel Corporation Ethernet 10G 2P X550-t Adapter". The switch is NETGEAR MS510TXPP.


    Here is the process to reproduce the problem:

     

    ethtool -i eth0

    I have had a similar problem in unRAID for a long time now where my card will negotiate 10GB at first boot, but then drop down to 1GB later.  A few months ago, I ethtool to force the X550 into 10GB mode and haven't thought about it since.  I'm not sure if the problems are related, but you may at least be able to recover your speed for now.

     

    One note, I turned "off" auto negotiate, but ethtool still says that it is "on."  But I am also connected at 10GB:

    Is your card Dell branded?

    Yes, the Unraid is installed on my Dell T7820 Workstation.
