Constant Upload Problems in Rogers AR

Hmm. Well, first off, when you upgraded to Premier yesterday the representative used the wrong code. Sorry about that. I fixed that issue, but that's not the main problem. (I swear, one day we'll figure that out.)

You've got what we flag as marginal-low upstream SNR on one of the channels and acceptable SNR on the other. (27.7dB @ 23.7MHz, 27.4dB @ 35.3MHz, 25dB @ 28.7MHz at the current snapshot) This probably means there's ingress somewhere, since the frequency with lowest SNR is around the amateur radio 10-meter bands if I'm not mistaken.

It will take me some time to check for any maintenance tickets around you and check a bunch of nearby modems. It could also be ingress on the drop from outside if absolutely everything else has been replaced inside.

Thank you so much for the update, really informative. And thanks for fixing the Premier, because I did notice quite the difference today.

The tech that replaced all the connections and splitters did mention that although I have RG6 cable, it appeared to be single shielded. This is cable I put in 2 or 3 years ago when I got it at the local hardware store. I don't know if you would consider this adequate, or if this would be part of the issue, but it still seems to be in good condition. But then again, the tech did run tests at different spots (at the modem, in the attic and outside where the cable comes into the house).

Again, I appreciate the work and time you're putting into this. Hopefully you'll find something conclusive, which I know is hard when it comes to an intermittent issue like this.

Kip,

First off, I'm glad that you guys are on the case, and I'm confident you'll get rid of the pesky issue.

I do see that it happened today at 11:22 am. It does seem like the outages happen at random times and they don't last long. I understand the short outages make it hard to catch.

As of example of how random these things happen, 2 days ago it happened around 7 pm, yesterday (10/22/2013) around 10:40 pm, and of course today at 11:22 am. Before this, I've seen log entries at other times like around 2am, 9 am, 3pm, etc. at different days of the week (some last several minutes).

As a preventive measure, yesterday I went around and removed any unnecessary connections and splitters, including an old VHS that was in line with a TV (which I suspected of because of how old it is). The power levels stayed very good at the modem. You can imagine my disappointment when the internet died around 10:40pm (LOL ... DARN!!).

Anyways, I wish you and your team luck with this issue. Thank you  for the update.

I am taking your advice from the dslreports forum and posting here.  Interestingly enough, just after I posted there this afternoon I saw the same two upstream frequencies were in "aborted" status on my modem and, sure enough, shortly thereafter (at 15:54 CDT) my modem rebooted due to T4 timeout.   So I decided that was a good time to leave the home for a bit .. and what do you know, there was a Cox truck on the main street and the tech there had been dispatched for an "outage" ..... I did not get to talk with him much, but he seemed frustrated with what he indicated was some intermittent issue that he had on the scope in the car (he pointed to it but I was not sure what I was looking at).

Honestly, I may not bee in the same area as you are in Rogers being here in Bentonville, but who knows .....  I just rebooted my modem to get a good clean signal so I could post here and this is what my upstream channels look like when things are good.

When bad .. the power levels are about the same, but the modulation shifts to "[ 6 ] 16QAM" and the ranging status often ends up "Aborted" particularly for the 287 and 353 frequencies...

As an aside .. this really started here in October after at least a year of no issues at all . and I too noticed this happens about every other day or so ... but sometimes daily.  When daily, I notice it more between midnight and 6am.  Today, however, was particularly bad with issues every few hours from about 6am on to 4pm.  We'll see if the tech in the truck was able to find anything.    Oh, I have a service call scheduled for Tuesday next week but considering how these problems only seem to come up every few years and they are always outside the home, I'm not hopeful that will be worth Cox (or my) time......

Update:  7pm and at least the 4th reboot due to T4 timeout today alone.  There may have been more since I'm not always watching the log as it wraps.  I guess I could call tech support again but instead I will wait for the tech to visit on Tuesday.  It sure looks like whatever the Cox tech was working a pole or two over from my home was not fixed (or more likely, trouble not found) :(

It seems that you're having pretty bad outages today. It reminds me of the consistent timeouts I was having last Friday night (10/18). I haven't had an outage since yesterday morning, which makes me think that you're not in the same affected group as me. I'm sure these guys will correct me if I'm wrong.

Oddly enough, you seem to show the same information that I've been seeing.

Well, let's see what they say about your issues today.

I wanted to give an update on the issue I posted. After some time Cox has seem to have done something that has greatly improved my situation, and perhaps all the other users that were potentially affected by this.

Since the last time they seem to have troubleshooted the issue, I've only had one outage (according to my modem's logs), and that was last Tuesday 10/29/2013 at around 11am.

One of the reason why I noticed a change on the service is because all 3 channels (2, 3 and 4) are constantly showing Upstream modulation in both [3]16QAM and [3]64QAM, which was never been the case before, at least not for all channels constantly.

Hopefully this post helps others, and I would like to thank KipK and the techs that worked with him to solve the issue.

Now, assuming that an amp was the issue, according to the tech KipK was checking with, then I will select that post as the answer.

Thank you so much for your help.
