Summary
Steps to troubleshoot the system if the network card is not recognized or not available in device manager.
Description
Embedded network connections are not working, and show a yellow triangle in Device Manager.
Resolution
Based on the information available in the readme notes for the Intel® Ethernet X722 drivers, the devices based on the Intel® Ethernet X710, XL710, X722, and XXV710 controllers may fail to load with a yellow bang error, on any version of Microsoft Windows* Server.
This may be because the device is connected to a switch that is not advertising traffic class 0.
To resolve the issue:
- Disconnect the device from the switch or configure the switch to advertise TC0.
- Restart the system.
