Random Network Resets, some days several times, after TLV-11 - unrecognized OID log

This appears to be a similar problem to what some other people have reported and ultimately only solvable by having an actual Comcast technician who can look at the back end to get involved.

 

My power and SNR look in spec, however the cable modem will reset at which point it generates the following error:

Wed Jun 24 09:17:10 2020 Notice (6)  TLV-11 - unrecognized OID;CM-MAC=88:f7:c7:90:83:aa;CMTS-MAC=dc:eb:94:b5:e6:b1;CM-QOS=1.1;CM-VER=3.0;

both of these errors today were associated with a few minute outage

 

sometimes there are more logs generated, June 17 was a particularly bad day:

Re: Random Network Resets, some days several times, after TLV-11 - unrecognized OID log

Spent most of 90 minutes on the phone with comcast who ultimately made some changes to the modem and in the back end and think they have resolved the issue.  I would have liked to know what sorts of changes were made, but they were working through a front line intermediary so I never talked to an engineer.

 

snapshot after they worked on it:  no obvious changes here...

Re: Random Network Resets, some days several times, after TLV-11 - unrecognized OID log

The signal stats are o/k but the error log entries indicate 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 will be able to poll the CMTS to see whether or not everything is in the green zone, see your node / cable plant and modem health, and also see a history plot for the modem. You should get a reply here in your topic. Good luck !

Re: Random Network Resets, some days several times, after TLV-11 - unrecognized OID log

Thank you! please do.  I spent an hour and a half on the phone and they said they made changes (which were invisible to me) but the problems started again yesterday evening and happened again today, so it is not resolved.  I have marked your reply "Best Answer" because I am sure escalation is the only good answer, thanks!  (for anyone else reading this, if you have something marked best answer already and you get a better one,  you can edit the old best answer at the three dots in the header and choose "not the answer" which will unmark that post -- then you can mark the new post)

Re: Random Network Resets, some days several times, after TLV-11 - unrecognized OID log

Somebody has obviously been into my comcast modem today as the wireless network it broadcasts is now gone and i am blocked from logging into it.

Re: Random Network Resets, some days several times, after TLV-11 - unrecognized OID log

I think there may have been a firmware upgrade done to the modem, and it was reset to defaults.  i got back into it with default credentials and set it back up to have the home internet and other services.  I guess i am just surprised this was done without any communication to me.
