Daily disconnects since service installed with no resolution. Logs attached
I've only been a customer for a couple of months but I've had very regular headaches - primarily, several generally brief periods of disconnect/intermittent connectivity every day. I have observed this both from devices directly connected to my modem/router and over 2.4/5GHz WiFi. There is no obvious pattern to the intermittent connectivity.
I recently had a service call about this after explaining my issues to phone support (they saw no issues). The engineer stated all power levels/etc were within expectations, and did tests both at the vault (conveniently in front of my home) and inside at the wall coax access point. He did note that the crimp on the line going into the house was shady and replaced it. He wasn't able to speak to my router logs but suggested I rule out the cable modem/router itself. I didn't think this was likely but was willing to try.
I've now reproduced the daily brief disconnects over the past three days since switching my Netgear modem/router to a new Motorola unit. I see no differences in behavior. I always see "MDD MESSAGE TIMEOUT" followed by "SYNC Timing Synchronization failure - Failed to acquire QAM/QPSK symbol timing" errors in the logs at times of connectivity loss.
I've also switched out my wall-to-router coax cable, though both runs were brand new. I feel that my next step is to request escalation to an internal engineer at Spectrum, as I have multiple days of logs with issues in hand. But I first would like to share with the experts here in the hopes you will see something of note.
The attached represent the event log and connection status from yesterday evening after experiencing some issues. I have other files as well. Thanks so much for any help you can offer!
