Why network interface card (NIC) is not detected in the system ?

Solution Verified - Updated -


  • We have onboard network cards in the system, but they do not appear in the OS to be configured.
  • NIC disappeared after updating to kernel to newer version and now driver no longer recognizes the installed dual-port card.
  • NIC does not appear in lspci output, Tried booting previous kernel but device / NIC still isn't recognized.


  • Red Hat Enterprise Linux (Any Version)
