My HP LAPTOP is not connecting to the Wi-Fi?

Hello everyone my laptop no longer connects to the WLAN the network is not a problem it works perfectly also the other devices connect very well to the WLAN except my laptop has worked very well to date. I have been using the laptop very intensively in the last six months and have never had any problems connecting the Wi-Fi. You have a solution for me that will work again.

Maybe the WLAN is deactivated or switched off by a key combination?

Unfortunately not either, everything is activated, even the networks are innate. The connection unfortunately does not work.
