i have comcast and everything was good for a while. i pay for 12mb down and i was getting about 17 down. then about two days ago i was getting 4 or 5mb down or less. since then i have had multiple comcast techs out and the cant figure it out. i tried switching modems, power cycles, and plugging in directly to the modem. the tech also switched out all the old splitters. now i am still getting the super slow speed and cannot figure out what is wrong with it. if you have any ideas please say them. thanks.
