Had no TV or internet issues for the first 6 months or so of service. Then internet and TV started cutting in and out. Wifi would shut off for a few minutes at a time, and all TV channels would be pixelated to the point of unwatchability. I called to upgrade the upload/download speeds for the internet for more devices on the WiFi and it helped for about a week. Finally called to get a technician to do an in-house visit and he changed the TV box, the modem, and the cables. He also checked the outside and inside connections. The TV pixelation got better for about a week before it started going back to being unwatchable. It seems to be fine for periods of time then gets worse at night.
Need another what? TV box? Modem? Cable? Tech visit? From all the other posts I have seen this is a known issue with Comcast that doesn't ever seem to get fixed. It seems the only ways to get this fixed is for Comcast to send a line crew to fix lines around the area (which apparently they also did around the same time the technician came to fix the in-home issues) OR I cancel service and go with another cable company. I just don't see how the service was perfectly fine for months and then all of a sudden has never been the same since.
