Played the ARAM game so hot as hell, it tripped the wifi and received total disconnection

...for about 6 minutes of the time, and in the end, i got marked as a Leaver. No, I'm not blaming Riot for this one, but this is insane. I have all the wifi to myself, since my brother kept lagging about more than half of all my games whenever he streams or plays league at the same time, but this disconnecting logic is super-r%%%%%ed.

The next time I hit the troubleshoot button, and it replies me with "please contact your internet administrator", no, not just contact. I'm gonna beat the black out of this "internet administrator" guy for calling it "surf in super-fast rate :D" for not doing his job right. I'm pretty sure everyone can relate to this, except some rich people who's gonna reply back with comments like "buy a faster wifi?".
