I have also just got Cox HSI. I use the same cable modem and to this day 
had no trouble with it. Most of the time I see slow transfer speeds it 
is usually the other end of the transfer being bombarded during high 
traffic periods. Just on a side note, that cable modem can get really 
hot. Make sure to store it in a cool place.
