In this case, the Wi-Fi icon is off, the laptop is not looking for networks ...

Most likely you need to install proprietary ...
look in Software & Updates > Additional drivers
or type in the console:
PS only for this you need an Internet connection,

I'm 99 percent sure that you have a hardware blocking on my Asus laptop , the
same problem was typed in
the
rfkill list all
command . Try following this article. ubuntuforums.org/showthread.php?t=2181558 the documentation says you can do rfkill unblock all But that never worked for me.
