Intermittent Internet

The past few weeks I have been losing connectivity continuosly thoroughout the day and night.  Cox Techs have come out and say that everything is good but the problem persists.

My Modem is a Netgear CM1000v2 which I just installed last Sept 2021 along with a new Netgear Router R6900P.  The folllowing Modem Log list is what is presently showing:

2022-02-18, 13:07:00 Notice (6) CM-STATUS message sent. Event Type Code: 24; Chan ID: 159; DSID: N/A; MAC Addr: N/A; OFDM/OFDMA Profile ID: 3.;CM-MAC=6c:cd:d6:7d:b6:64;CMTS-MAC=00:a5:bf:0f:89:65;CM-QOS=1.1;CM-VER=3.1;
2022-02-18, 13:06:38 Notice (6) CM-STATUS message sent. Event Type Code: 16; Chan ID: 159; DSID: N/A; MAC Addr: N/A; OFDM/OFDMA Profile ID: 3.;CM-MAC=6c:cd:d6:7d:b6:64;CMTS-MAC=00:a5:bf:0f:89:65;CM-QOS=1.1;CM-VER=3.1;

Can anyone tell me if this is a Cox problem or mine?

Thank you.

    Hi@July21

    I can understand the frustration of an unstable internet connection. There are no issues in your area. Have you tried bypassing your router and hardwiring directly to the modem to see if you are still getting these drops?

    I am getting the same errors on my log, and these have now persisted after a tech came and replaced a line that he reported to be the cause of upstream interference.

    widermouthopen, not sure about the OP, but just this morning, i have had over 7 instances in the log each of "CM-STATUS message sent", both code 16 and code 24. Also have had over 10 t3 timeouts. This has just been in the last 2 hours...
