Wi-Fi no internet access while gambling. Why?

I noticed that my laptop is always denied access to the Internet when I play Fortnite and that every five minutes (by the way only with FritzBox with IOS 11). When I log in and out, everything works again.

So with me it is eg so that when others lie with me on the Internet or my Internet also crashes or goes slowly.

Just try fritz.box with the password of your router does not login wlan password in your router.

Then go under the tab Internet and Filter.

Then go to the Prioritization tab and prioritize your laptop.
