so if i go to play toribash then somehow it breaks my internet connection and it not Works than i wait like 3 minutes and it again Works with toribash than it again not Works when i exit from toribash and then my internet works

Restart the connection by resetting the router.

it's very weird how connecting to a server renders your internet useless for 3 minutes, how is your internet data?
If you are running out of data, it could be a problem

Now i am on my grandma s computer i removed my internet so i went to my grandma it now not works :/ i need to call someone to fix it

Or , if you have iphone / android , try making it a mobile hotspot ^^
I always do that when i'm on airport
