Good Day!
Im trying to install Ubuntu Mate 18.04.4 on my Thinkbook i13S (no lan port!) with a bootable usb. When i boot via the usb i do have a normal working internet connection. But when i install ubuntu Mate and reboot i no longer have internet access ("no wireless extensions"). I already tried various things like installing the driver from the usb/pool directory but it does not work.
Please treat me like a complete noob, this is my first Notebook im trying to set up with ubuntu mate.
I can provide more information like command outputs but please tell me how to copy the output as i do not have internet on the laptop and cannot post from it.
Attached is the output of the commands sudo lshw -C Network, iwconfig, and lspci executed on the installed version and the usb
From usb:
