Connection keeps dropping

Good day,

We had VM for a while now but last few months it keeps annoying me. So the situation is that the Internet just going for 30-60 seconds and then coming back. It is no a Wi-Fi and router (Hub 5) still shows white, steady light. 
Every time I do testes on VM website, it comes back hat i need to reboot the router, as there is nothing wrong. 

We had VM technician coming few times, replacing socket, cable in house (from the socket to the router), replacing router itself. I then just gave up and got 5G as a backup....

Could someone have a quick look at the below logs and let me know if there is anything 'obvious'? I just do not want another technical coming and saying 'nothing is wrong', etc.. 

Thank you in advance

    The log tab is a lot less enlightening that one might wish.   Could you share the information from the Upstream and the Downstream tabs so we get to see any issues in the signal power levels / errors  / modulation modes.

    Hi Sebsebseb,

    Thank you for your posts and welcome back to our community forums. We're here to help.

    I'm sorry to hear you've been experiencing some connection issues recently. I've checked over things on our systems and I can't detect any faults currently that would explain these issues you've been facing. Are your service issues ongoing today, or have things improved since your posts?

    Thanks,

    So we had engineer coming yesterday (thanks Matt). He checked all connection and signal, etc. Said nothing wrong and it must be a router. New router fitted, but after few hours connection was playing up again. Today, we are back in square one with internet connection dropping every 30 minutes or so. 

    New graph shows lost packages at the same rate as before replacement router

      I have the same issue, getting in touch with a human voice is nearly impossible, my only option is to dump VM and try another provider

        Hi bfgpete

        Thanks for your post - sorry to hear you're also struggling with your connection.

        I've had a look and a lot of your downstream channels are out of specification, so I'll need to schedule you in with a home engineer visit.

        I've dropped you a PM so I can look into this further for you.

    Not sure. We had the engineer here again yesterday. Replaced piece of cable, tested all. But it did not fix the issue. 
    I will give a few more goes with them, but they cannot see any issues, yet it keeps dropping. It's a bit of a shame, as when it works it is brilliant. But for nearly £80 pcm I need something reliable

      Hi Sebsebseb,

      I'm sorry to hear you're facing some ongoing service issues. I believe you're already discussing this in more depth with one of my colleagues via private message. We'll continue to assist you further from there.

      Thanks,
