My internet just turns off on my laptop?

My internet on my laptop goes off every five minutes, nowhere else. Box is on, everything is normal, but where the WLAN symbol is actually there's this globe with this crossed-out circle. It says that my Wi-Fi is switched off and that I can decide whether I want to switch it on manually or after a certain time. But I can't turn it on either because it's on, when I click on it it turns off. My internet doesn't work then, I restart my laptop and then it works for a short time and then exactly the same thing happens again. It only works when I connect my LAN cable. It worked again for a couple of hours and now it's exactly the same again.

You have to upgrade the router and the WLAN card in the laptop to 5 GHz. Then the WLAN runs on the laptop

How about the lankabel as a permanent solution?

Otherwise it sounds in my opinion. After a software problem e.g. The drivers for the WLAN card or the WLAN stick. Especially since it also works on all other devices.

To be on the safe side, I would chase a virus scanner over it and see if it finds something and reinstall the drivers for the Wi-Fi hardware.

The lank cable is out of the question for me, I have to lay the cable from the living room to my room and that's just annoying because then I can't close my door either. I've had it like that for several months now and it's annoying. Now that I have the new internet and the connection is good enough, I want to use my Wi-Fi too.
