Thank you for contacting Intel.
I see that your network card is already on the latest version. Please refer to the website below to see if driver updates is available for other components.
This link will take you off the Intel web site. Intel does not control the content of the destination web site.
I branched out your post since you are encountering the problem on Windows* 7, while the original post is on Windows* 10.
On this moment we are experiencing probably the same problem.
The Dell Latitude e5570 and the Dell Optiplex 7040 both with Intel i219-LM nic are giving troubels.
When you unplug the networking cabel from an actieve machine ( user is logged in) and then reconnect the network Cable then the nic doesn't see the link. The lights on the nic stays off. ( not always after one utp cable disconnect and reconnect. This varies between one and 10 timed Other machines that we have Dell Latitude E5550 and Dell Optiplex 9020 both with Intel I217-LM nic doesn't have this problem. We have tried several outlets and several L3 switches from Cisco. We already tried the latest drivers from Dell and Intel. Windows update installed a driver from juni 2015 as the best driver. That didn't help. Does anyone know what de reason is? Maybe top intelligent driver/nic software that conflicts with the Cisco L3 switch??
