Hi,
I have seen several posts with Started Unicast Maintenance Ranging - No Response received - T3 time·out issue but am not getting resolution from reading or from technicians. Pretty much same as this one https://forums.xfinity.com/t5/Your-Home-Network/Connectivity-issues-Started-Unicast-Maintenance-Rang...
Had a tech change some cabling and suggest that if it persisted, that it may be my router/modem so I even tried a new one. Same issue with losing connection.
Here my current info:

Even though the signal stats looked o/k at that snapshot in time, the error log entries confirm that something is going on. Perhaps there is noise ingress into the line(s) somewhere.
There are other signal stat figures that can't be read by the modem. They are the "Upstream Rx Power" (Upstream Receive Power Level), the "Upstream SNR Ch." (Upstream Signal To Noise Ratio), and the "Upstream ICFR" (In Channel Frequency Response). These are as equally important in diagnosing connectivity issues as are the modem's stats.
I'm going to escalate your issue to the Comcast corporate employees that are available to these boards. They can check the CMTS (Cable Modem Termination System) for any real time degradation and / or error reports, see your node / cable plant and modem health, and see whether or not everything is in the green zone. They can also see a history plot for the modem and poll for those upstream receive signal stats.
You should get a reply here in your topic. Good luck !

Hello @budgie99, thanks for reaching out to our Forums! I would be more than happy to further investigate and look into these connection drops you're experiencing. I can also get a tech back out if needed as well. Can you please send a private message including the full name as it appears on the account and your full name if different?
