Re: Cable Modem download stream with correctable uncorrectable in the millions

you have loose, corroded or bad connectors or splitters . Make sure there's no extra splitters or open ports and that all connectors are a tad more than finger tight.

You're also getting severe broadcast TV ingress at times. Are you in LA?

repost the entire down and upstream pages. and the error/event log

 

I'd call this in as intermittent slow speeeds with downstream partial service errors.

Re: Cable Modem download stream with correctable uncorrectable in the millions

I don't have any splitters in my house or outside in the termination box.   I checked for tightness that looks good this just started happening this week as I have checked the status report on the cable modem daily.  I appreciate your help!   I live in North Carolina near Raleigh.   Thanks again below is the event log.

Re: Cable Modem download stream with correctable uncorrectable in the millions

[ Edited ]

Well now that's cute...Robot Sad

 Looks like the CMTS you're on has all the traffic passed on the first 8 ds channels and they're loaded with correctable and uncorrectable errors.

 You need twc out to fix this, the in house tech needs to escalate this to tier 4 to fix whatever is wrong in the CMTS programming and possibly a failing 8 channel qam shelf as well as the bucket truck guys to fix whatever is wrong out on the street trunk lines.  The In house guy needs to replace all your connectors, especially out at the street.. Can you post a photo of the tap off block you're on?

 

No simple fix, at least 2 things are wrong and handled by 3 different TWC departments that don't talk to one another very well.
