Always One Channel High SNR

[Greenpalmer]

I always seem to have one downstream channel with high noise - it's always either channel 4 or channel 12 with a bit of overspill into adjacent channels.

Every time I reboot the router within a very short time channel 4 or 12 goes down to 33.

Also I often get only 16 or 32 qam on upsteam channels instead of the regular 64.

Router stats and log follow:

Good Afternoon @Greenpalmer, thanks for your recent update, and I'm sorry to hear this fault has re-emerged.

I've looked into your local area, and I can see that an outage is currently effecting the local area, and is estimated to be fixed by 22 JUN 2022 at 13:05.

We're sorry for any inconvenience this may cause you, and other effected users and will do all within our power to have this fixed as soon as possible.

Kindest regards,

David_Bn

[Greenpalmer]

It's well past the date given for the fault to be fixed, the service status lines - both online and phone local area status - are stating that there are no faults, but despite rebooting and resetting the hub the errors are still clocking up in their millions on the two channels that have very poor SnR. 

This really must be resolved - it has been dragging on for a very long time.

[Ashleigh_C]

I'm sorry that you are still noticing these issues @Greenpalmer

I have checked and I can see that the outage has been extended with the new estimated fix time of the 6th of July at 12.06pm

Are you able to let us know how things are looking after this time? 

[Greenpalmer]

The fix time is always extended - sometimes it goes on for months!

But if the fault has not been fixed why is there nothing on the service status or the local fault line?

[Alex_RM]

Afternoon Greenpalmer,

I'm sorry for any confusion, not all issues are listed online.

Checking things today it does look like the issue has now been resolved, can you confirm how your services are running?

There has been no improvement. This issue has been dragging on for over a year now and despite often being told that the fault is being fixed it never is. It is quite apparent that Virgin have no idea what is even causing the problem.

Hi Greenpalmer, 

Thanks for coming back to us on this. We're sorry to hear you are still having an issue with your services. 

Checking things this end, your signal and power levels are all within optimal range. There are no issues showing in the area and all is looking good. 

From the stats you've posted, there are a few Post RS errors but there's been no reboot on your hub since the area fault was resolved. 

Can you please reboot your hub for me? Leave off for a few minutes at the mains and then turn back on so the logs are clear. Hopefully things should be resolved for you then but if not, come back and let us know. 

Thanks, 

[Greenpalmer]

Kath_F - I had rebooted the hub after I was informed the fault was fixed, but to prove my point I again rebooted the hub after reading your message and now a week later here are the stats and you can see that the problem has not been fixed:

They’ve clearly got issues with the 219MHz frequency in terms of noise ingress. One thing I urge you to do is check in with a couple of neighbours and see if they have the same issues. It helps the case as to what sort of area fault there might be. Downstream SNR should not fall below 34 if you are to avoid uncorrectable errors, which means lost packets.

Thank you for your reply Greenpalmer. 

I am sorry to hear there are still issues with the service. 

With this being the case, I would like to run a few more tests from our side and potentially arrange a visit from a technician. 

I am going to pop you over a private message to confirm a few more details and this will be available via the purple envelope on the top right of this page. 

Speak soon,
