Here are a few networking commands that will provide more info about the driver, about the card, about its configured parameters and speed, and about its connection statistics.

Note: The ethtool utility is included in some but not all unRAID distributions. See here for more information about ethtool, and a download link.

    • lists the installed kernel modules, including your network driver
  • ethtool -i eth0
    • displays the network driver being used by your network chipset (for eth0), and its version
