Steps to troubleshoot the system if the network card is not recognized or not available in device manager.
Embedded network connections are not working, and show a yellow triangle in the device manager.
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.
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, and restart your system. This may occur with any Intel Ethernet X710, XL710, X722, or XXV710 device on any version of Microsoft Windows Server*.
