Re: Sigh... here we go again... should be getting 30, back to under 6

Please send the signal level page agin so we can view corrected and uncorrectible errors on DS channel 6. Remember, DO NOT restart, reset, or power cycle the modem, that resets all counters and logs to zero . After 3 days we pretty much know there will be a few hundred counts. More than that means problem is not fixed.

The problem is that they won't come out until it stops working... so I guess I wait.  Also, if breaking and reconnecting outside is a temporary fix, then I'm going to have to deal with them doing that at least 1-2 service trips.

 

I hate TWC... wish I had another option.

Re: Sigh... here we go again... should be getting 30, back to under 6

It's to the point of not being intermittent, it has an EASY TO FIND AND MEASURE LOW s/N, the s/n is a constant unuseable 29 dB on that channel.

 Anything below 32 is pretty much unuseable.

 Since you're measuring speeds below 80% they are supposed to send out a tech

That's just it... since I broke/reconnected the connections outside, I consistently get 32+ Mbps, even with the low SNR on Channel 6.  Ie., right now SNR is 31db (all others are up at 37), but I have no packet loss (using PingPlotter) and am getting a download speed of 37.1 Mbps and it's been steady for going on a week.

 

At this point, I'm wasting my time if I call them.  I have to wait for my speed to go in the trash again.

You could have the same situation I did, where the leakage was further upstream [between my tap and the CMTS] and was being amplified DS along the trunk route.   Responding to several complaints of intermittent video breakup, TWC replaced about 500 feet of 35 year old 7/8" trunk line feeder about 200 feet upstream of my tap location.  My uncorrecteds suddenly dropped back to single digits right after they spliced in the new stuff. 

The first step has been to identify the most likely cause of your problem.  To do that we relied on the signal quality data from your modem that you posted here.  Don't give up hope that TWC will eventually find the leakage and make repairs.  The search for ingress points is a very long process, and could be coming from connected equipment on customer premisys.  All it takes is one jumper with a bad connector, something the bucket truck guys can't easily track down from the street.

Key phrases from your post:

 

"several complaints"

 

"relied on signal quality data from modem"

 

"hope"

 

"TWC will eventually"

 

"very long process"

 

I'm with Dave: they're going to look at the modem's signal (which you rely on) and see that it is good; hence, there is no problem on their end.  Case closed.  This is why I haven't opened a ticket.

 

The truth is, if maintenance and customer service policies were mission-focused rather than quarter-to-quarter-penny-wise-dollar-dumb-focused, it would take ONE call and ONE maintenance ticket rather than constant hounding and hoping.  If/when that changes (like if/when they get competition), it's simply not worth the hassle.

Unfortunately, we are at the end of the line -- there is no cable beyond our house.  If no one complains upstream of me (which is what the field guys have always maintained in the past), then I am the lone voice in the wind.

 

To me, that says that the problem is occuring between me and the next internet customer upstream and limits the area of focus.  To TWC, I am a single person and don't matter that much.  They know I have no other broadband option in this area and am basically stuck... even crap <4Mbps is better than any other option (ie., dialup).

 

As long as my signal currently holds, there is nothing to contact them about.  I am currently getting advertised speed, even though SNR on Ch6 is at 30db.  Until I am stuck well below advertised speeds, for an extended period of time, all they are going to say is that my speed is as advertised.

 

I had hoped Charter would bring a change in operating philosophy, but as of yet it's same old, same old.

look at your neighbors signal level/ s/n on 687 Might help localize where the issue is.

Any friends that are ham radio operators?

 They could look for egress on one of the pilot frequencies and that's probably where the ingress is getting in as well.

So I guess you'll have to wait until something with your connection fails.

 

Perhaps contact your local squirrel union... Smiley Very Happy

Charter DID change the philosophy. now it isout to maximize their investor profits by further deferring needed plant maintenance at the expense of long time TWC customers. But what goes around comes around: As delivered network signal quality degrades further, users will go elsewhere to obtaIn working internet service.
