Re: Bonded downstream channels

So, still ingress.  The tech and I went through everything here on premises, so it's got to be out in the lines on the street, I guess.  Anything I can tell the tech if I call him again, to get him to look further out?

Out of personal curiosity, how do you tell which station it is from the mHz?

 

Also, I see some folks on this Connectivity forum post photos and jpg images nut the option to attach an image when I compose a message does not allow for browsing to anything on my computer..... it just has a line for "Source".  How do I post an image here?

Re: Bonded downstream channels

see the mountain after the paper clip?

it allows you to post an imgur or other remotely stored image here

must have a .jpg or .png extension

 

 and yes, you're having an ingress/ noise issue cewntered around a local tv broadcast channel or channels

Re: Bonded downstream channels

Yes, I was referring to that icon, it's only for remotely stored images.  That was my question, that there is no way to directly add an image from my computer.  Thanks.

So do I just call the tech (he left his number) and tell him you told me on the TWC forum that I have an ingress issue centered around broadcast TV signals, and it needs to be chaecked further up the road?

 

One thing I recall, there's been a broken cable hanging from the line at the street that used to feed the house across the street but is no longer used.  It dangled on the ground for a couple of years and TWC would not come out and do anything about it because it wasn't "live". I finally got the tech that came out last week to go up with his bucket and cut it off higher.  Shouldn't it be *disconnected* from the street line totally?  I can't see how it is attached because it's buried in the neighbor's tree branches.

Re: Bonded downstream channels

....and now I'm down to 6 download channels following another partial fallback around noon today.

Re: Bonded downstream channels

[ Edited ]

hanging cable: as long as it's not connected to the tap off block, it's not an issue.

Print out that signal page. Unplug the modem for 5 -15 minutes, plug it back in, it may lock on 8 channels, paste that here, then again a half hour later, hopefully none of the channels get ingress timed out and there's high correcteds/ uncorrecteds on the bad channels

By looking at it now, 561, 573,597, 603 are getting trashed! Thats's TV channels 29,31,35,36

 and per this printout, 3 are within 25 miles of you:

Re: Bonded downstream channels

OK, I turned the modem off for over 15 minutes, now have 8 consecutive channels.  Will post another look in about 30 minutes.

Re: Bonded downstream channels

Dang.  I chacked again about 30 minutes ago and it was virtually unchanged from the last post, now at noon it has already dropped channel 8 for channel 13, suddenly.

Re: Bonded downstream channels

Your modem should be getting ready to drop and replace downstream 4 and 13, based on the rising number of uncorrectibles caused by the broadcast ingress leakage.  That leakage can be anywhere upstream of your line tap, or another user on your tap itself. If intermittent it could be caused by wind flexing a broken connector or piece of cable.  Now you can better understand why these don't always get fixed by the first tech who responds when you call for help.

Re: Bonded downstream channels

karlbeckman... and sure enough, this morning I have one new entry in the logs:

 

TimePriorityCodeMessage

Jul 05 2016 05:27:273-CriticalR02.0No Ranging Response received - T3 time-out;CM-MAC=30:60:23:cc:fe:fc;CMTS-MAC=00:17:10:8a:37:0e;CM-QOS=1.1;CM-VER=3.0;

 

...and the modem dropped channel 4, as expected, replacing it with channel 15.  I guess the only way I can get this looked into is to call back the tech (who left his cell number when he left) and tell him what I've been told here.  I don't know if he will act on it or not.
