Performance issues with CM500 and Time Warner
My internet continues to drop and/or my speeds come down to a crawl below 1MB. I have made multiple calls for service, with technicians dispatched to home to find nothing with the signal and pointin...
Hello pquihuis
You log shows T3 timeouts which means you are getting noise on the lines I would call the ISP and have them send a tech out to check the lines see if they can resolve the issue. Below I left a description of a T3 timeout.
"The cable modem has sent 16 Ranging Request (RNG-REQ) messages without receiving a Ranging Response (RNG-RSP) message in reply from the CMTS. The cable modem is therefore resetting its cable interface and restarting the registration process. This typically is caused by noise on the upstream that causes the loss of MAC-layer messages. Noise could also raise the signal-to-noise ratio (SNR) on the upstream to a point where the cable modem’s power level is insufficient to transmit any messages. If the cable modem cannot raise its upstream transmit power level to a level that allows successful communication within the maximum timeout period, it resets its cable interface and restarts the registration process. This error message is DOCSIS event message is R03.0, Ranging Request."

Thanks Darren,
I will reach out to my ISP. I also see that Channel 2 on the Upstream is showing "Not Locked and Power shows 0.0dBmV", is this also an issue?

Also, should the Uncorrectables be zero, as last week they were in the 5 digit number range?

Hello pquihuis
You will have to ask the ISP about that and the uncorrectables being a low number is fine.

I have followed up with Time Warner and their L3, but they are continuing to point the issue to my Netgear CM500 modem. Even after sharing my event log highlighting the errors, they continue to claim that all signal levels are within specification. To get past the finger pointing, I will rent their modem to assess if my problems continue. I'll keep you posted.
