I've contacted Comcast 3 times this morning. First time, they reset the modem (which I've already done numerous times, along with shutting everything down and restarting everthing starting with the modem, then the router, then all the other "connected" equipment). Cable modem reboot had no affect and we were disconnected. I waited to see if the problem would re-occur. About nine minutes later...drop. Called back. This time the person I spoke to wanted me to reset the telephone modem and stated this would fix the problem. Ok...pushed the reset button on the Arris internet phone modem and was promptly disconnected from support (surprise). Took about 3 minutes for the next disconnect. Called back. Tech scheduled for sometime between now and 8pm tomorrow.
The issue started last week, as we were starting to thaw out after being below freezing since December. I work from home (I'm a programmer for HP) and VPN into my corp. network and I keep getting disconnected. Very frustrating. Phone support is wanting to blame my cable modem (which I own). I suspect otherwise. Any help?
