I have tried various methods to install WiFi drivers on my machine. I have downloaded the rtl_wifi directory and have installed the necessary firmware too. However, when I run the command:

sudo modprobe -r rtl8723de

and

sudo modprobe rtl8723de

I am getting this as output:

modprobe: ERROR: could not insert 'rtl8723de': Operation not permitted

Please help me find a solution to this as I am a student and need WiFi on my machine almost daily.
