I suddenly have started getting speeds of about 1.7 mbs on RCN cable in NYC. I used to be getting at least 3.8 mbs. How could it change so suddenly? And it isn't traffic because i've tried late at night even on saturday its slow. I called and they said because it's above 1 mbs they can't do anything......ugh whats goin on?

Did you check for packetloss?

The likely cause, is a new configuration file.

All glory to uncappers. (within reason.. just to get what you pay for)
