I have 2 computers at my house that get alot of use. one desktop and my laptop. Some times if i am streaming a full length movie or even youtube videos they buffer and load at a decent enough speed to watch without much interruption. other times its brutally slow to the point where I just give up because it take literally hours to buffer and load a one hour movie. What the hell is going on? The only thing I can think of is that the desktop has a tv tuner and if someone is watching cable tv maybe that hogs all the band width and makes my connection drag royal ass. I dont know shit about computers so if anyone can help me understand my plight please explane.
This is probably your problem. I don't have the fastest internet connection, I average about 4Mps on a speed test, and if I want to stream a HD broadcast I have to shut down my other computers and Xbox to get a clear, lag free stream.
