Wi-Fi all over the house when I start my notebook?

I noticed that whenever I start my notebook, the internet connection is gone. Get it quickly, because everyone gets upset right in the house what is going on with the internet again. Strangely, exactly whenever my notebook comes on. These are wlan routers from Kabel Deutschland. Anyone have an idea? Has only been like this for 2 months. Not before that.

Oh yes… For me, the laptop would intentionally run 24 hours.

Ask the question Kabel Deutschland. They have to know their devices.

Have the same problem… My laptop with a Mc server on it goes on and when a person joins the Wi-Fi router crashes
