    No Ethernet option after update

    I am running ubuntu 18.04.2 LTS. After latest update, I do not have internet. I even have no ethernet option in Network Manager. Ifconfig -a gives me just lo interface. Between updating and restarting computer I changed kernel from linux-image-4.15.0-43-generic to linux-image-4.15.0-45-generic.
    lspci -v

    I solved it by booting to previous kernel (Advanced options)
