Network disappears after a while on the laptop?

Re

My problem is that when I use my laptop and watch videos online, for example, my internet does not work after about 30 minutes (always different) and I can no longer connect to the Wi-Fi. LAN works anyway. I can only connect to the Wi-Fi again after I restart the laptop.

It is not due to the Wi-Fi, I have already reset and restarted the router several times.

Wi-Fi works perfectly on other devices.

Driver is up to date

Was also with my laptop, the Wi-Fi receiver was broken

Re

Maybe you know how i can find out which Wi-Fi receiver my laptop needs?

No, i sold the laptop to a hobbyist and bought a new one because it was very old

How far is your laptop from the router? And how many walls are in between? Do you happen to live in a high-rise building or a large building with many residents?

Live alone with my family in a house and between the router and me maybe 5m and a wall
