Connection - latency and reliability issues

Good afternoon, 

I’m hoping someone can help - lately we’ve been having severe reliability and latency  issues with our connection. Even on Ethernet, the ping spikes up to 150ms and is incredibly variable, making it difficult to play games. Even using 5G proves itself to be better.

We have an engineer visit booked for later this afternoon, but believe that this will (at best) fix the reliability issues - we had an engineer visit last Thursday that improved nothing. 

My daughter is autistic and this is severely impacting her and making her feel very stressed.

I submitted a complaint to the exec team on Friday  - but this was just forwarded to the regular complaints team - how is this acceptable to your company? Not to mention they haven’t responded. 

Please could you assist with this matter urgently - I can provide the complaint reference if necessary?

    In so far as the Community can assist, perhaps you would post your power levels for the upstream and downstream together with the Network Log.  The red bits at the top of the BQM suggest an upstream issue (noise) that we might be able to confirm from the data I've requested from you.  The Community has excellent technical knowledge.

      Thanks - what's the best way to do this?

      When I try to C&P, it comes up as a table which won't post.

    You go into the hub GUI (192.168.0.1) and on the front page look for > Check Router Status.  Click that and go to each of Downstream, Upstream & Networklog pages, using copy and paste to place the tables into a your next message.

    for that.  The Network Log suggests that the upstream is 'having fun with itself'.  There appear to be power issues with the DOCSIS 3.1 channel.  This will affect any time sensitive application.

    With regard to the downstream, please check the stats again and tell us whether the Post RS Errors are rising.  They usually occur during a modem reset when it hasn't yet sync'd with the other end, and the numbers then don't move.  This stat refers to irrecoverable data packets.  If they (Post-RS) are rising then there is noise on the downstream.

    A visiting tech has the necessary instruments to confirm noise or otherwise but I've no idea whether that was done.

     

  • Thanks.

    Just had another look and they are still rising.

    The Tech on Saturday did check the wiring outside the house for definite, but I'm not sure what the findings were (just said a cable pull was needed without any reason why)

    Do paste that page please.  The Forum Team will see what you've posted and likely arrange another tech visit.  Then you will be able to prompt the tech to look at the stats and check for noise.
