Re: CM1200 - Lot of correctables and uncorrectables
Hello, I'm all of a sudden experiencing the smae issues with a netgear cm1200. HAve had techs out multiple times now who have all been great but continue to lose service. The last technician was very good and allowed me to show him the modem information directly frokm the modem admin rather than looking only at what comcast provides with their internal testing. HE was seeing that everything was fine through comcast testing and couldn't understand why the upstream light was blinking equating to not having a lock. We could see there are 4 upstream channels locked, however, the OFDMA channels are having trouble as shown below.
Also showed him the log where I am continuing to see the folling over and over coinciding approximately with the service dropping.
Confirmed the latest firmware is active on the modem. Did another factory reset with no issues resolution. Installed new connectors on the coax which which looked good but did for good measure. The line coming into the house is a home run from the outside termination box to the modem and was newly installed with the service. It is a direct shot through the attic to the modem with no splitters or wall pates on the line. The technician today also confirmed there is no leakage on the house line and is nearly a perfect connection to outside. I also care for my neighbor network and found similiar errors being taken on his modem which is an arris surfboard 6900. Hasn't occured for him very often since the 8th but is the same erros and harware MAC address.
Since the above is my neighbor with service out of the same cable and "Tap", i believe it's called, and is showing the same type of error events in his modem log by a different manufacturer, I am confident the issue is in the outside plant or there is an issue with the firmware Comacst is pushing.
The tech changed my drop today, moving it from aerial to buried. The tech out on the 8th repaired a piece of cable going into the neighbors house behind me that had a squirrel chew on it believing was causing interference. Service worked for a few hours and was then out again which seemed aligned with the winter weather, freezing rain, snow, and high winds that occured that night. I've always had intermittent service issues with weather events and wind. The tech today put in to have a line tech out which can take up to 72 hours.
Is anyone else seeing issues like this that they have been able to resolve. Paying too much to have problems like this and wasting too much time with having techs out. This has been an ongoing chronic issue with service.
