    The card is detected (as shown in lspci), there might not be a driver for it.

    Looking up its PCI ID, it doesn't seem to have a driver in the kernel: https://askubuntu.com/questions/1071...n-ubuntu-18-04

    FYI, ifconfig doesn't show interfaces that are down, you have to append '-a' to it.
