Hi,I have face my internet speed problem recently. Before this,my internet top speed can reach until *00kbs. But recently, it just reach 20kbs for the maximun.
I think is my housemate limited my speed. He is the one who be the server in my house. He claimmed that our router got some problem and can not be the server,so he is using his computer to be the server.

Could he limits my speed? What can i do to make my speed more faster?

Sorry for my English...
