Be sure to call your local Comcast billing office to report these outages and get bill adjusted for the time you lose connection.Nothing gets you more service than asking for billing adjustment.I have done this twice .It got me a bill reduction and quick repair.
We switched from satellite to Comcast Cable for internet 3 months ago. For the last 4 weeks our service has been out for 3-4 days each week. The first time, the tech came out and said squirrels had eaten the lines and he fixed them. The next week we had to wait 5 days before they came out and it went back on by itself before they came. The next week, the same thing. They came anyway and checked everything, but no problem showed up - because it was working. Now it's out again and they can't come for 2 days again. We replaced the modem and that's not the problem. All the wiring is new. Comcast claims there's no service outabge in the area, it's just us. Help!
