woah guys, thats funny, i always have the same problem! (i live in montreal canada if it helps)
a little story, i have been with 5 dsl companys (local in montreal) i kept switching companies, telling them why i am switching is because i keep losing connection to the internet, etc.
so finally i realized that its not the company it seems, either my modem, or something else.
now it does it on and off, but its the worse whil i am playing a game.
anyway, just wanted to say its not only you guys who have this problem, lol.
