Okay so i currently am running a nighthawk router and a netgear modem. We have a lot of stuff connected and there is never an issue. I can download games on my xbox, no issue. My brother can download something on his xbox or computer, no issue. But for some reason, on my computer, JUST my computer no other system, if i download something, even so much as open steam and it starts updating a game, my internet instantly shuts down except for that download. Nobody else can even open a web page while my download is going. Why?? Any help is much appreciated.
