Cable is a shared connection. My connection came to a stand still because all my neighbors were surfing too much. Tony the cable guy hooked me up... so to speak. He put me on a separate connection. My internet connection is now flying.
There were so many shared connections in this box that Tony could not figure out which cable was mine. I had to go up to my 4th floor apartment and yell out the window when my cable TV went offline. "TONY... IT'S OFF.. OK... ON... OFF AGAIN" I'm sure my neighbors appreciated all the yelling.
