Have an issue with intermittent signal. Engineer has replaced damaged cables outside and now the Virgin hub inside. Still have issues with the signal dropping out. Happens with the Virgin hub in modem mode or not.

If there really is only one upstream channel at 32qam... then there's your issue. The down channel power levels are on the low side too anf there are post RS errors. Strt from a clean sheet and do this...Switch the Hub off and unplug it from the mains supply for five minutes. Whilst it's off, do a quick check that all of your coax and ethernet cable connections are in nice and "finger" tight - at the Hub and wall box and also at any connectors etc. Ensure there are no “unterminated cable loose ends. Disconnect all the connections and reconnect to be sure. Also check that the internal wiring is ok with no kinking or chaffing. When its light, check that all looks good with the outside cabling and wall box (no “staples, etc.,) piercing the cables. Then switch the Hub back on and leave ~5 minutes When all done, check back in the settings and ensure that the RS error counts and T3 errors have all reset to 0. Then check every hour or so to see if they start reappearing - they shouldn't. If they do (particularly the postRS and T3 ones) you have a problem (noise) that only another Tech visit will sort.Also check the Upstream channels have reappeared and all QAM’s are at 64

Thanks. Done the above. Cables all look fine. Still have issues with intermittent connection/ packet loss.

Check for local issues here:https://www.virginmedia.com/support/help/service-statusRun the 'Still having issues' check if nothing is returned.

Had one installed by an engineer, same issue

  Yeah I have been through all the steps and had 2 engineer visits - none of which have fixed the issue.

    Hi arcircus,
    
    Thanks for taking the time to contact us via the Community. It's lovely having you on board with us in the Forums. ⭐
    
    We're sorry to hear that despite several engineer visits, you are still having an issue with your connection. Checking thins this end, I can see a more senior engineer appointment has been booked.
    
    Can you please let us know how this visit goes?
    
    Thanks,

Since you have an intermittent signal and not a total loss, you won't be eligible for automatic compensation. When it's finally fixed you will have to raise a complaint and insist on some compensation.

  I have turned my router off as it was a waste of electricity given how unreliable it was. If you can’t run a video call because the signal is so poor i would consider that a total loss tbh. I look forward to my future arguments with Virgin CS 🙂

    Thanks for coming back to us arcircus, can you please provide us with an update on the services.
    
    There doesn't appear to be any local issues, and the hub appears to be unresponsive.
    
    Have you switched the hub back on at all?
    
    Thanks,
