Your wireless mouse and keyboard, while using the same frequency as two of the wireless standards, isn't using the same protocol. Interference is a possibility if you're using wireless - though your question is lacking information on how you're connected to the internet.

While MS claims its unlikely there's reports of it on their own support site. Their troubleshooting hints seem a little useless though - here's a google cache cause their site is down

On the short run, try switching to wired net or keyboard/mouse to see if there's still an issue. Try switching wifi channels to see if that helps too.

That little useless things worked :) Thanks! – Ümit AKKAYA Nov 3 '12 at 13:58

If I had to make a guess I would say that you're using a USB network card. When you download at the full rate it might be blocking your keyboard and mouse from communicating with the computer as well.

Try to use an Ethernet connection to your computer and see if that helps the problem.
