My ISP is BT. I have 3 housemates excluding me who use the same wireless router. I experience terribly slow internet when one of my housemate (his name is Tom) starts using his computer. The internet isn't slow when the other 2 housemates use their pc. I always receive the maximum wireless signal so its not the issue here. Is it possible for someone to deliberately set up the connection so that he gets fast connection while giving others slow connection? Any ideas on how to resolve this without getting a new ISP for myself?
