  1. Not to keep this issue open, but the backup wasn't the cause of my initial issue.  It was an extra problem because of the reasons you mentioned, but the bandwidth was not working properly before I upgraded the firmware.

    This has happened in the past with the bufferbloat sliders/percentages not functioning and I never used a backup after a factory reset in those times.  I tried this time and learned to not use backup to a previous firmware.

    What's bothering me is that this is an intermittent issue I've encountered before, and the only way to fix it is with a factory reset. Is it possible for you to remotely link up to my router the next time this might happen? Thanks again for the help.

    All is working now- fresh start on latest firmware.


  2. Yes, the speeds were correct. No vlan or pppoe settings. I just did yet another factory reset and it's functioning normally now, but this is a reoccurring issue I've run into in the past 12-18 months. Have always had to do a factory reset, but this time it took 2 times, plus an error from restoring from backup settings.

    Are there any other users having similar issues over long periods of time?  It's quite a headache to have to do factory resets when bufferbloat features aren't working

     

    Thanks also for replying so late over there across the pond- appreciate it.


  3. Hi all- 

    I am not able to adjust my download/upload bufferbloat settings.  I can adjust the sliders, but there is no increase or decrease in speeds via dslreports.com/speedtest.

    I keep getting 70-75mbps.  All Testing Is Wired!

    When I ran the config wizard to retest speeds, the results were what I am paying for (177down 12 up)

    I have: 

    Tried sliders, checked to see if download and upload were enable for sharing, checked the "never" box above the bufferbloat sliders and unchecked it several times, factory reset, new firmware- rolled back firmware from the factory reset "r-app" error. Reset the cable modem (Arris SB8200), power cycled several times both modem and xr500.

    IPV6 is disabled.  I even tried doing a speedtest with the QoS disabled box checked.

    I still only get the 70-75down

    Please help!

    EDIT:  I have noticed that all testing DOES show that my upload speeds are correct when I adjust using the sliders, etc....  It's only my download speeds.  Also, when I decrease the download speeds on the slider.  It does lower the mbps overall (download), but at 100%, I top off at 70-75.  Should be 175-180

    Thanks in advance

     

     


  4. I've looked on the other threads and have followed all the advice I've seen posted.  I have: restarted router, flushed cloud, factory reset router-  

    I have Playstation listed and have tried rebooting with and without filtering on.  I have set my location in desired location that I want to connect to, but I am always connecting to Dallas dedicated server with a less desirable ping.  I am trying to connect to the Iowa servers that give me my best ping.

    When I expand the geofilter ring to include dallas, I  connect to it, but game will not start.  When I shrink the geofilter to exclude Dallas, I see that I am still trying to connect to that server.  Could it be that it is an incorrect location?  I don't know, but no matter what config I use, Apex is unplayable for me with GeoFiltering active.  Will only work in Spectation mode.

    Am I doing all that I can?

     

     


  5. Update:  After tons of complaining and filing an FCC complaint, I was finally able to get a crew out here to see the noise on my line while it was happening.

     

    I am supposed to have 4 upstream channels; only have 3, and then during peak times, the overload is causing packet loss and upstream is only functioning on 2 channels....

    The CMTS needs to be looked at.  Any cable internet users know how long it takes for these types of issues to be repaired at the headend?  


  6. Wow! That’s rough mate, it must be really frustrating. It could be that your ISP is majorly over subscribed in your area and there’s not enough bandwidth to go round at peak times.

     

    Put your Comcast modem back in, connect directly to it and run PingPlotter again, that way you can show your ISP that the problem is theirs and nothing to do with your home network.

    Yeah, I would do that, but then my wife will be upset with me for taking the wi-fi down.

     

    The speeds i pay for (100mb down, 10mb up) are not slowed during these problems, so I don't think it's an overloaded node.  I do think it's noise on the lines.  I'm going to continue to be a pain in the ass with Comcast until they get techs out here during the time it happens.

     

    I do have pingplotter charts that show me testing directly from the modem only, so I already have that ready for Comcast if they come at me.  I couldn't find people reporting ping issues caused by their netduma, but want to eliminate that. 


  7. Hi Keith - could you please share your tests with us if you have screenshots? It's usually the case that technical support officers from big ISP's like Comcast either over-complicate the issues or blame the other network devices that don't point back to them. In our experience, ISP issues are usually a dodgy modem, an over-subscription to that ISP in your area or a bad line.

     

    First off let's go through your setup and issue. Which model of modem do you have supplied by Comcast? Is your setup Modem > Netduma > All Devices as it should be? Are there any other routers / switches in the mix?

     

    What latency issues are happening specifically? (i.e spikes, jitter, packet loss, increased base ping, sawtooth-pattern ping spikes etc?) We can derive that info from any PingPlotter test you share with us :)

     

    Have you tried another modem? Do the issues happen with the Netduma disconnected?

     

    My equipment is SB8200>Duma>devices

    I bought my own modem (Comcast leased modems are trash/ have Intel Puma chipset)

     

    Every night, usually starting at 8:30pm est, my ping fluctuates all over the place.  Lasts anywhere from 1-6 hours.  Techs have terminated all my ends on splitters, put a new drop to the tap from my house, and all of my testing has included my previous leased gateway, a replacement comcast gateway, and now my new modem that I purchased.

     

    The following pingplotter charts are with modem>duma; wired only connections.

    Now the latency is bad, but it used to be even worse a few weeks before these recent links.  The techs have been in my area placing filters on homes putting too much ingress back on the line, but it is still not ok in the evening.

     

    I'm going crazy trying to get techs out here while this is happening so they can isolate the noise.  Almost not possible to tell where the noise is coming from if they are not monitoring it while it's happening.  Pulling my hair out knowing they will soon start over and blame my home network.  Posting here to see if a remote session on my duma will provide me information to make sure it isn't my Duma causing these latency spikes-

     

    EDIT:  here is a link to full PingPlotter session.

  8. Copy/paste job.  Posted in wrong forum, sorry!


     


     


    I've been having latency issues in the evenings for the past 6-7 weeks.  This issue is currently being tracked down by my ISP.  All the techs that have visited have basically eliminated my home network and equipment from causing the latency and packet loss issues.


     


    I'm posting here because the ISP support is having trouble isolating the cause (suspect it's ingress from other users in my area/cable internet) and I don't want them to start over at the beginning and suggest that I disconnect my Duma.  Frustrating part is the issue is always in the evening hours when local techs are off the clock, so I'm not certain that Comcast is even seeing what I'm seeing.  My modem specs during the time in question are within Comcast's suggested levels.


     


    Can someone on the tech team please remotely access my Duma and run some sort of diagnostic tests and share the results with me?  I have ton's of data (pingplotter, modem specs, tracerts) suggesting the latency issues are on outside Comcast infrastructure and not my home network, but I want some more data to back it up.


     


    I can share any/all information, but I want to do it in a private setting as I have not edited any ip or mac addresses.  I just want to show the engineers that my equipment is not the cause.


     


    Thank you for your time-

  10. Hey everyone!

     

    The past week has been very frustrating.  Attached are pingplotter screenshots.  Every evening around 6, 7pm, latency starts to go crazy.

     

    I've had a tech visit on Friday.  Replaced modem, line from drop, straight to house.  The line goes direct to modem, no cable tv feed.

     

    Posting here to try and understand what the data is showing and what tips you may have to help me escalate this to a higher level of technical support. I am losing my patience trying to explain over, and over, and over again.  The techs on the phone (and housecall) don't seem to understand the difference between bandwidth and latency....and I need to talk to somebody who can help.

     

    Comcast xfinity

    west michigan

     

    Tested friday, wired via Duma (gateway in bridge mode to duma)

     

    Tested today, wired, directly to gateway (factory reset on Gateway)
