On the one hand, the wi-fi is sometimes disabled, but in my assumption, this has to do with the relatively poor Wi-Fi reception, since the router is in the basement. The wlan strength is enough for me though.
Today has repeatedly disabled or did not deliver a steady performance, so I restarted the laptop, which has always helped.
The "Will be restarted…" Screen took much longer than normal, it ploppte briefly Bluescrenn with the. Logo on and the laptop restarts normally.
And suddenly the Wi-Fi function is gone. In the Internet settings the tab wlan has disappeared.
Even after several reboots continue.
What can I do?
Sounds like driver issues for the wireless adapter.
Look in the device manager. Reinstall or update driver.
I would recommend downloading an installation for Windows 10 on another PC or laptop on a USB stick or a CD. If you have done so, go to the bios on your laptop where your Wi-Fi is no longer working and choose the first boot variant as the USB where you have downloaded your installation for Windows 10. After you have done it you have to save the settings and leave the bios. After that (if you did everything right) a screen with a blue background should open after a while. If it has opened, you only have to download Windows 10 so follow the steps. If you did not understand me correctly you should definitely look for Windows 10 with USB on YouTube.
