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}

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.

When switching to the Embedded adapter in the Targus Docking station, I'm authenticated in less than 10 seconds:
Wired 802.1X Authentication succeeded.

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?
