I have replaced modem, router, coax cable, splitters, all on my end. have called comcast 4 times, Had a tech out, said my signal and lines are good. What next to do.

 

I have this error from my modem.

here are my down stream and upload signal.

bonded channels.

1. qam256 7.6dbmv SNR 41.3 DB correctable 0 Uncorrectable 0

2 8.3dbmv 41.4 SNR 8.3

3 8.0dbmv 40.8 SNR 8.0dmbv 

 

and the rst are the same with all correctables and uncorrectables showing zeor. I can't type the rest caue they're so many any way I can post the image. Any help would be great! No sure where to go from here since and tech was already out and still having the issues.

Please also post the upstream channel signal stats and the balance of the error log entries in their entirety.

downstream

Up stream

opps sorry forgot that.

So you're asking for the event log from the modem? If so that has my Mac address and I will have to delete that out. Is that what you're asking for?

You didn't post the balance of the error log entries in their entirety.

I am sorry why was my topic moved? One other posted the same problem.

Yes. And it's only the CM and the CMTS MAC addresses.

and those are just the signal levels. Let me know what you want to see and i'll post.

My pleasure !

Okay, thanks for the help.

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 !

Not yet if they haven't replied here.

They are currently having issues with the escalations coming into their team correctly. They currently are working to get this resolved, so they will most likely be delayed for multiple days. I can try re-escalating this after a while.

Hey ther EG. Having got any reply yet. Do  you know if they checked my connection?

Ya cause I am really getting close to closing my account, I would have thought the tech would have checked all this. Not some expert giving his time on a forums. No point intended toward you but little frustrated that it took the forums so far to figure out a problem and not when I make 3 phones calls, a tech visit and still having issues. So yes please, try to send again. Good grief. I ordererd Tmobile home internet and just waiting for modem to come. Will be testing that while I wait for all this to get corrected.
