I'm sure it works fine, but they must have standards for us to adhere to for a reason. My guess is that you probably haven't saturated the network with too many simultaneous torrents or something.
I've seen so many things affect the whole service. Things like improperly set torrent programs (I'm guessing a virus could silently max out your bandwidth?) or a cell phone on WiFi stalling the internet.
One person had a garage door monitor wired to the modem. Whenever their second set top box was turned on (technically always on, just standby) the internet would stall out. I swapped their equipment one by one, but the problem finally stopped when the garage door thing was unplugged from the LAN.
IP sure can do some strange things :-/
