So for few days it is so that my internet connection on all devices deteriorates sobal I start my laptop. Does a vlt know why that could be? All updates are installed and completed and have windows 10. Laptop is a medion:-)
This is more related to the router and the way all devices are connected to it.
Can I do anything about it? That's only recently
Can't judge without knowing your technique.
Do you need to download Netlimiter, because you can see exactly if your laptop downloads something in the background.
