High latency errors (full logs & BQM attached)

I've had VM engineers come out and replace the whole cable inside the house, and the outside cable to the cabinet was replaced in full a few years ago. Paying for 1000 up / 100 down.

Still I'm having many high latency errors.

Anyone see if there is a problem?

      Hello 877,

      Welcome back to the Community and thanks for taking the time to post. I’m sorry to hear of the issues that you’re having with your connection at the moment. I've been able to locate your connection and run some tests on it and your SNR(Signal to Noise Ratio) levels are too low across some of your channels that will need an engineer visit to resolve. I can arrange the appointment from here but would need to confirm a few details via a private message, that I will drop over in a moment. Please look out for the private message and we can get started.
      Kind Regards,
      Steven_L

    VM care about speed not latency mostly

    If its not caused by you maxing out your speed without you setting up BWM/QoS by own router its VM upstream.

    Also note in some cases if you do setup BWM/QoS you are still subject to VM overall rate limiting of available bandwidth like if you rate limit BWM/QoS at 500Mb but VM can't give you that speed due to load in the area you can buffer on there BWM/QoS.

      Useful.

      The latency isn't worse at peak times, no capacity issue evident.

      There is a clear SNR issue, the 3.1 upstream's modulation is flapping...

      ...which will cause latency spikes. There are clearly uncorrectable FEC errors on it so there'll be retransmits, causing latency spikes, and a level of packet loss if it gets too high.

      6    OFDMA    200    74000000    59

      The 3.0 upstreams all have T3 timeouts. 

      The network as a whole has a high noise floor. You can tell this by looking at the lowest upstream channel which sits in the noisiest part of the spectrum.

      Channel    Frequency (Hz)    Power (dBmV)    Symbol Rate (ksps)    Modulation    Channel ID

      This would normally be 6.4 MHz wide taking it down to 20.4 MHz, it's been adjusted to 1.6 MHz wide leaving it between 22.8 and 24.4 MHz to avoid the noise it would be hitting between 20.4 MHz and 22.8 MHz. This comes with a loss of capacity of 75% of the channel however this was presumably preferably to having it constantly dropping modulation and even then erroring.

      There are likely long-standing and difficult to resolve issues on the local network. VM engineers will try and patch it up and get them all running smoothly but in the longer term the fix is Project Mustang.

      Messing with QoS will do absolutely nothing the issue is at layer 1.

      Took me less than a minute to read the original post and less than 10 to compose this one. Being conscientious isn't a big time sink, far better than posting random irrelevant content on QoS/BQM wasting the time of everyone reading and your own writing it.

        What a great (but complex) reply :-) It seems that adjusting SNR will help but long term it's the full fibre solution for the overall network if I understood correctly.

        Physically - what could the engineer do about this? I presume change the dB filters to raise the signal strength...funny because they said they already did that when they attended a couple of weeks ago.

         

        Thank you!
