NV - Intermittent latency spikes and packet loss, mostly in the evening

Maybe somebody here wants to see if they can explain what is going on.  For months now I have had short periods of poor service almost always in the evening.  I have had multiple techs out who could find no issue.  I have replaced every piece of equipment on my side of the connection, including the cable modem, at the suggestion of cox support.  I have been put on "home monitoring" and been told nothing indicates any of the lines leading to my modem need to be replaced.  I sometimes get error messages in the event log of the modem and have corrected/uncorrected packet counts but those do not correspond to the time of these interruptions.

Nobody seems to want to admit there is an issue or seems to get back to me with any information.  I started documenting the issue at the end of December here https://www.dslreports.com/forum/r32616178-NV-Intermittent-latency-spikes-and-packet-loss

Reset modem around noon after the first graph but it doesn't seem to matter.

@Llama42, I can certainly understand your frustration with this ongoing issue and I appreciate that you have provided the detailed information. It does look like there is an issue on hop 2 and that is typically between the modem and the outside tap. I recommend sending us an email with your full address and link to this thread to cox.help@cox.com so we can look further into this issue for you. Thanks. -Allan, Cox Support Forums Moderator.

No uncorrectables or event log entries during these periods.

Seems like it has to be usage related.  Ingress or congestion that increases as people use it more during the evening?  Tech is coming out in the morning.

Hey I just wanted to come here and post that you are not alone.  This has been happening quite literally for the past probably 9 weeks in my area of Vegas (Paradise) as well and of course they never find anything wrong.  It's beyond freaking frustrating at this point and the only thing they can tell me anymore is 'be patient' because 'they are upgrading the area'.  That doesn't help that I maybe have service 30-40% of the time.

@magis123, I am not detecting any packet loss on your modem, however, I am seeing an excessive number of timeouts. Please make sure all connections are tightly secured and free of damage. This includes any splitters you have in the home, as well as the copper needle at both ends of the coaxial cable. The timeouts occurring might be a signal related issue. -Kevin

Trust me I've done that.  Your tech has done that including removing all splitters from my home and that the line comes directly from the onsite hub.  It consistently drops out when using any peer to peer networking (specifically destiny) during periods of peak traffic. Note I am NOT file sharing, I am playing a game.  I had a tech before say that if I stop file sharing I won't have these problems as you throttle connections that use P2P file shares.  I am NOT file sharing, that is the network architecture the game is built on (peer-to-peer hybrid mesh).

I literally have tried EVERYTHING as did your tech that came out.  You suggested i buy a new modem so I bought two different brands and have the same results.  Do you realize how frustrating this is?  The tech said the on site hub needs replaced but won't be replaced because of the 'neighborhood i live in'.

He was just back out here for one of my neighbors having the SAME problem and he told her the same thing.

Magis123, we apologize for the ongoing service issues and I do understand this has led to a frustrating experience. I'd like to have another technician go out to the home to investigate this further. To schedule an appointment, can you please include a link to this forum thread and email us at cox.help@cox.com? -Kevin M. Cox Support Forum Moderator

I've gone ahead and done that.  The power ranges on my modem are just WAY WAY out of whack and I'm getting a huge amount of signal noise.  It's ridiculous.  I have to teach from home and today I could not stay connected for longer than 25 minutes without my connection resetting.

Just an update, working with a tech who at least seems committed to figure out what is wrong.  Found small amount of ingress on my line and some on one of my neighbors.  Replaced the coax run from my dmarc through the attic to the cable modem but no luck.  You can see some downtime at 2pm from replacing the cable and then around 4pm we see the issue is still present.

The next day (Friday) the issue was later but quite pronounced for over an hour at around 11pm.

Noise seen from the neighbors line was even less than mine which makes me skeptical removing it will solve the issue but we will see.

Llama42,

From what you're seeing and reporting, there still appears be an intermittent issue. I understand you've just recently had an appointment completed by a field technician. If the issue is intermittent and not happening at the time of the appointment, then this can make it difficult for the technician to diagnose at the time of the appointment. We're reaching out to our local field team to help pinpoint the next possible step for this issue you're seeing.

Respectfully,

Dustin

The tech I've been working with is great. The tap should be getting replaced within the next few days and will reevaluate after that. Just documenting the plot from 2020-03-18 here:

Yesterday ~11:40am they finished replacing the drop line and issues came back after 1pm.

At ~2:20pm I removed a UPS and any other equipment that was near the modem just to see.

At ~8:10pm I bypassed all networking equipment and ran directly off the modem with a different ethernet cable.

At ~9:20pm I restored networking.

Issues persisted until about 1am when things settled down. The problems are definitely more prevalent during daytime hours and more frequent since people started staying home due to the coronavirus. Working from home during this involves attending teleconference calls which makes this type of performance issue quite apparent.

Just comparing yesterday 2020-03-19

to the same day 2 weeks ago 2020-03-05

you can see how much worse it is since the state shutdown and start of social distancing.

Hi Llama42, our records show that this issue has been resolved. Are you still experiencing packet loss? In reference to people working from home, our network is built to handle peak use in the evenings to meet the full needs of families’ demands for entertainment, school assignments, and late-night deadlines. This same network is available to support our customers if they were at home throughout the day. -Kevin M. Cox Support Forum Moderator

Actually I don't have a good day since the drop cable has been replaced.  I assumed the new one would be better but it's possible it made things worse.  Every day looks like this now

I'm not sure why it would be marked as resolved.  The drop line was replaced and the packet loss continued and is now significantly worse.  Issues that were confined to the evening now occur throughout the day.  However, it always seems fine from about 2am to 7am (off peak hours).  It's my understanding the tap should be getting replaced but I don't think it has yet.  This is what today looks like so far:

Are you sure its not just "data capping"?  Its not likely something cox will admit to doing, but apparently common in their business.  I used to have the same issue, then I paid for their unlimited data and rarely have that issue anymore, although there are rare instances where it still happens.  We went through the same, "check your wires", " buy a different modem" etc suggestions they seem to be offering you as well, until we got fed up & just started paying for unlimited data.

I had exact same problem for like a week already. I can't even play any game since the high latency hitting my internet so hard. COX needs to do something about this because of this an essential time while most people are staying home and using their internet. I wish I can use another service provider.

@Whatever95, Are you experiencing this issue with all devices in the home or just one? Also, can you provide some traces as well? -Allan

Hi Llama42, please bypass your router, connect a device directly to your modem with an ethernet cord, reset the modem, and then run another PingPlotter traceroute. We're unable to troubleshoot through the router, so bypassing the router temporarily allows us to focus solely on the modem's performance. -Becky, Cox Support Forums Moderator

Hi Becky, thanks for your response.  I have done that multiple times over the past 4 months.  You can see I tried that 8 days ago in my comment here https://forums.cox.com/forum_home/internet_forum/f/internet-forum/24997/nv---intermittent-latency-spikes-and-packet-loss-mostly-in-the-evening/98004#98004

Hi llama42, in order to better assist you with this inquiry, we will need you to bypass the wireless router and perform PingPlotter tests while hard-wired directly to the modem. Please include a link to this forum thread and email us at cox.hlep@cox.com for additional support. -Kevin M. Cox Support Forum Moderator

I do not use a wireless router and I have done test directly connected to the modem many times.  I have already emailed and linked this thread.  The tech I was working with said he would escalate the issue last Wednesday but I have not heard back since then.

also on one of their last visits that we didn't have to be home for they "split a node" because one of the techs monitored the modems and found 80 percent saturation. and nothing if anything its gotten worse. he sent me a picture of his computer screen where he submitted a ticket for it on a cox coral website. case id ESR000003149212 enterprise special request ticket. there is that if it helps with anything because apparently cox employees see everything fine when i call and im being told there will be a 70 dollar charge for the next tech to come out this Saturday.

Hi Fabian, if the issue is related to the Cox equipment or Cox wiring, you will not be charged. If the technician determines the issue not to be related to the Cox equipment or wiring, a $75 fee may be assessed on the account. -Kevin M. Cox Support Forum Moderator
