Uncorrectables on ALL downstream channels. What could be the problem?
I live in Springfield, VA. I have a Netgear CM600 modem and have been receiving uncorrectables of hundreds of thousands and millions in a very limited uptime (< 24 hours). I am having this problem on every channel operating between 649-813MHz. The amount of uncorrectables varies, but is still very high for all of them.
Alongside this problem, I have been experiencing network instability and modem crashing about every hour or so.
Side note: I have tested a different modem (Arris SB6190) and have gotten the same, if not worse, results.
The event log for each modem has showed me a different combination of errors like:
-RCS Partial Service
-SYNC Configuration Time out
-Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received - T4 time out
-No Ranging Response received - T3 time-out
Cox Technical Support, including the technician who came into my house, said that everything on their side looked good (GREEN).
This problem arose after changing my Motorola SURFboard modem to something from this decade (ie. SB6190 and CM600) due to a small UPLOAD SIDE packet loss issue (1-3%) I was having while gaming online. Never any crashing until now.
Between the times when these errors occur in the event log, my internet is lightning fast (besides the upload packet loss issue still being present).
>These are the values for DOWNSTREAM with the Netgear CM600 at an uptime of around 90 minutes.
| <tabindex=-1>Downstream Bonded Channels | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
UPSTREAM:
| <tabindex=-1>Upstream Bonded Channels | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
(I assume that I do not have the option for 8 Upstream channels because the Arris SB6190 did not even list the last 4 channels)
Could this problem possibly be inside my home?
The technician took out a splitter from my setup and placed my internet cable on a splitter with an amplifier. The problem does not seem to have changed though.
I have another, higher-level, technician coming in 2 days. Is there anything that I can show them to help pinpoint the problem?
gjett1 Actually, I think the best people to contact would be the AWS customer, which is the gaming company. The trick will be to get the attention of upper management with specific details to support your case. Otherwise, your complaint will likely be immediately filed in the "circular file" system.
Send a detailed letter via certified mail to a member or members (i.e. CEO, Senior VP). It may help to select "restricted delivery" which means that either the addressee or an authorized agent for the addressee must sign. That's an extra attention getter. Otherwise, whoever normally gets the mail at the company will sign for it. You don't need to pay extra for a return receipt unless you want to.
If that fails, then file an online complaint with the Better Business Bureau (BBB) against the gaming company and reference your certified letter(s).
How does that sound to you?
gjett1 Oh, I see now. The Motorola SB6121 was only a 4x4 modem, while the Netgear CM600 is a 24x8 modem and the Arris SB6190 is a 32x8 modem. In your case, you appear to have gone from 4 downstream channels to 16 downstream channels. Your connection doesn't appear to be handling the new total of 16 downstream channels very well.
I think you are correct when you stated that the issue now points at Cox side (facilities, cabling) after having tried 2 newer modems, both running 16 downstream channels, with the same result. As an aside, I wonder if your SNRs are rather misleading because of the high downstream power levels.
All the best in getting Cox to resolve it quickly during the next visit.
