Its a plant issue and charter hates to admit it. Your wires weren't the problem. Also the bandwiths are probably so congested right now with a lot of people getting cable internet. Cable hasnt develop that technology yet versus satellites in the sky they just launch another satellite and open it for more bandwith. Have you ever notice that your internet on cable runs slower at night and faster during the day.
