Now, my computer's internet goes fairly fast. However, when my sister turns on hers, and starts to download files, my internet level starts to drop significantly. I, then, start to experience connection, which is annoying. I heard something about limiting bandwidth, however, I can't find that on my router's main page.

BTW, I have a windows 7 computer, I am just using an old pic.
