So I'm thinking Comcast is going to ask me to leave their service. I've posted my issue to the Comcast Direct forum and gotten no response. I'm getting persistent (can last for up to 16 hrs.), intermittent problems that cause me to lose one downstream channel (always 22) entirely, get millions of uncorrectable code word errors in the channel range of 18-26 and have the signal levels on my 3 upstream channels jump from 43 to 51 dB. Comcast has replaced my amplifier, replaced my amplifier power supply, put a new splitter on my internet drop (it goes to the XFi gateway and one digital TV), and sent out a truck to do some work to correct signal issues on their side of things. I used to only get slow (50 - 80 Mbps) speeds on my gigabit connection, now I have streaming video just lock up completely. When things are working normally I get consistent 945 Mbps download speeds. I was using a Netgear CM1150V modem which did just fine until all this started. I swapped it our for a new XB7 gateway to prove to Comcast it was not my equipment. The XB7 doesn't do any better and has spontaneously rebooted several times in a few days which the Netgear modem never did.
I'm really at my wits end. All my connections on and in the house have been checked and tightened, and the wiring looks good. Anybody have any suggestions other than to call Verizon and sign up for FIOS? I used to have a FIOS land line so I already have the fiber to my house and the ONT, although I hear Verizon is not the most reliable for service, and their customer service is worse than Comcast.
