Why doesn't wifi work in Ubuntu?

Question

linux

I decided to install Ubuntu on my Xiaomi laptop 13. I did it for the first time and I don’t know what it is and how ... The problem is that WI-FI does not work stupidly. It doesn’t turn on through the terminal, it doesn’t turn on through the interface (((I can’t go back to Windows anymore, there’s only one PC. Please, I really need help :(

It looks like the system thinks you have a physical Wi-Fi switch, even though you don't. This should help: https://manunalepa.wordpress.com/2017/06/05/xiaomi...
That is, for starters sudo modprobe -r acer_wmi, and if it helps, what's in the article to make the fix permanent.
