So i have been having this problem for a while now.
I do not get disconnected but it seems that whenever my DSL connection starts using a lot of bandwidth it then crashes to zero..
I took this picture to demonstrate streaming a youtube video. You can see at first it is streaming fine, but then starts doing weird stuff. There was no one else on the line. Any other info needed i can obtain if some one thinks they might know whats going on.
My guess is that the copper of the house line is old and bad and causing problems.
