  • Which 18.04 did you install? 18.04, 18.04.1, 18.04.2, etc.. and RTL81111/8169 is an ethernet nic (not wifi), did you try anything from https://help.ubuntu.com/stable/ubuntu-help/net-wireless.html.en – guiverc Apr 05 '20 at 01:00
  • Hi your right, the wifi details are this:

Made it simple, after all, when installing Ubuntu you have to check "Install other firm software..." it will ask you for a password for "Unsecure Boot".

When rebooting, it will send you to a blue-screen asking for permission for "Unsecure Boot". There you will have to introduce the password and select the option.
