Hi. If the wi-fi on your laptop stopped working unexpectedly, it looks like Windows 10 installed some updates that affected the wireless adapter. The first thing I would do is try rolling back the wi-fi adapter driver. In any case, you need to go into Device Manager and see if the Wi-Fi adapter is working normally. Maybe it needs to be “activated”.

Next, I would experiment with the Fn + key combination responsible for enabling/disabling wireless networks. You can press this combination once and reboot the laptop.

I think that the problem is in the driver. If the problem with turning on wi-fi appeared suddenly, then most likely after Windows 10 update.

And try also to turn on the wireless adapter as shown in this article: /solving-problems-and-errors/how-to-enable-wi-fi-fi-in-windows-10-wen-there-is-no-wi-fi-button-and-the-error-failed-to-find-wireless-devices-on-this-computer/. In Network Connections.
