I can download games at 1-2 mb/s, and can browse the internet perfectly fast and like I said, last visit i played games just perfectly. So her wifi is great. However, i think i kind of found the problem

I installed IObit, which comes with a game booster program thing that stops unnecessary programs, and when I ran it and it stopped a bunch, all games worked perfectly. So I am thinking there is something on my computer that perhaps recently got there that is interfering with the wifi...?

Idk...
