    lost my wirless connection with ubuntu 19.04 upgrade

    I upgraded to ubuntu 19.04 recently and lost my wireless access with RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller. I saw on the web that this a known issue. Will this issue be fixed with the release of ubuntu 19.10 which I will upgrade to. If that is the case then I'm ok with that. If not I'm using a USB device which works 99% of the time. I would rather use the one that is installed. Can anybody walk me thru proper way to get resolved the problem. THX

    lost my wireless access with RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller.
    As the name implies, this is an ethernet adapter, not wireless.

    Let's find out what wireless device you have. Please open a terminal and run:
    Code:
    lspci -nnk | grep 0280 -A3
    rfkill list all
    Post the result.

    spci -nnk | grep 0280 -A3
    It was supposed to be:
    Code:
    lspci -nnk | grep 0280 -A3
    Are you saying that there was no output at all?

    Is the wireless enabled in the BIOS/EFI?

    No. It is, as far as I can tell, unrelated.

    So far, your internal wireless card is not recognized at all by the operating system. Again, is there an option in the BIOS/EFI to enable or disable wireless? Please check. If there is none, the I strongly suspect that the internal device is defective; that is, broken.
