    Unable to use 802.1x on Wired Intel cards

    gerald.mathieu

      Hello,

       

      We are currently testing the implementation of 802.1x authentication using a computer certificate on our network.

      The laptops used are Dell Latitude 6220 and Dell Latitude 7240 (I218-LM and 82579LM cards) and a Targus Universal USB Docking Station. (OS: Windows 7 Enterprise SP1)

       

      When testing the configuration, the laptops are not able to authenticate when I use the Intel NIC giving this error:

       

      Wired 802.1X Authentication failed.

      Network Adapter: Intel(R) Ethernet Connection I218-LM
      Interface GUID: {fce65701-1056-495e-8d36-f2c7b29dd4a2}
      Peer Address: CCEF48D73A6B
      Local Address: ECF4BB1443D7
      Connection ID: 0x9
      Identity: -
      User: -
      Domain: -
      Reason: 0x50006
      Reason Text: The authenticator is no longer present
      Error Code: 0x0

       

      Sometimes, I receive a strange "succeeded" message telling that the network does not support authentication then restart the authentication process :

       

      Wired 802.1X Authentication succeeded.

      Network Adapter: Intel(R) Ethernet Connection I218-LM
      Interface GUID: {fce65701-1056-495e-8d36-f2c7b29dd4a2}

      When switching to the Embedded adapter in the Targus Docking station, I'm authenticated in less than 10 seconds:

       

      Wired 802.1X Authentication succeeded.

      Network Adapter: Targus Giga Ethernet

      Reason Text: The operation was successful
      Error Code: 0x0

       

      I've updated the laptops to the latest BIOS available, updated the Intel drivers to the latest available without success.

      Any idea of what is causing this problem?
