Pc game ruines internet connection

[Benedoge]

Hey there,

 

lately I installed the quite old online firstperson shooter Heroes and Generals.

Since I did not enjoy playing it I unistalled the game.

The problem I have now is the follfowing:

 

Every I start an online game such as Warframe,LOL and Warthunder, I lose my internet connection after

2 minutes. Strangely I can watch movie on the internet shortly after I closed the running game.

 

I have no idea what is going on .

Please try to help me.

Can you test with another PC? Other thing to try, reinstall network drivers, reboot router, restore Windows.
