Cannot find wireless NIC device model or a driver.

[shaii]

Hello.
I cannot find a device name for my wireless NIC installed in my HP laptop, as there is no driver installed and I wished to locate one.
It is a fresh install of Kubuntu and the wireless NIC has never worked. Kubuntu 18.04LTS is of the latest version and I have generated a wireless-info.txt utilizing the script in the pinned post, and am willing to supply more information if needed.
I will attempt to respond as promptly as possible to any replies.

Thank you.

First step, disable Secure Boot in BIOS/UEFI
Then in terminal do

sudo apt-get install dkms git build-essential
git clone -b extended https://github.com/lwfinger/rtlwifi_new.git
sudo dkms add ./rtlwifi_new
sudo dkms install rtlwifi-new/0.6
sudo cp -r rtlwifi_new/firmware/rtlwifi/ /lib/firmware/
echo "options rtl8723de ant_sel=2" | sudo tee /etc/modprobe.d/rtl8723de.conf

Reboot
