WLAN connection on the laptop keeps breaking off?

If I want to connect my laptop to the WLAN then everything works as usual. After about 3 minutes the connection breaks off and I have to reconnect everything manually. For example, my cell phone doesn't have the problem or my sister's laptop doesn't either. When I connect my cell phone hotspot to the laptop, it works normally and nothing breaks off. Can someone help?

If I were you, I would update the drivers for your laptop.

The "Driver Booster" software is available for this purpose. The "Free" version is sufficient for this.

If that doesn't help, you have to take a closer look at the whole thing. It can then be related to the corresponding wireless network card, for example. Usually, such a driver update helps a lot.
