Drop to 0.0 upload speed for the past month

[manytentacles]

Hello. 

Since the start of August we've been seeing a drop in upload speed from ~100MBps to 0.0, sometimes maybe 1. VM sent out an engineer, re-pulled our cable and yet the issue persists. A family member in the area said they experience the same thing and then finally VM said it was an area SNR issue and they would fix it.

When the 2 week fix date came it did get sorted, but within a week it was back. Then a fix for 2-3 days and then it was back. I've called them every time and had responses from 'we will log the call' to sending me unwanted and unneeded equipment. I've said many times that it is the same issue as before and there are other people in the area getting the same problem, but the customer 'service' don't seem to be able to think beyond the script.

I'm getting a little tired of having to start the same conversation over and over with the call centre as I just want to continue with the original fault that obviously hasn't been fixed. It's super frustrating. 

you can see from the BQM (they are all like this) that it starts regular between 4 and 6pm and lasts into the night.

Is anyone able to advise or someone from VM able to contact me about this particular issue so I don't have to log this as if it's not been going on for a month?

cheers

Upstream connection looks dreadful - can you do this first.

______________________________________________

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 a Tech visit will sort.
Also check the Upstream QAM’s are all at 64 - if they are still dropping (to 32/16) then see message 3 here…

thanks. I'll give that a go and come back.

Please have a look at this thread and then possibly hook up with the poster.

If you are in the same locality as the other person, there is an area issue (the other OP has checked with neighbours and they have the problem too).  If you are in a different locality - as in nowhere near - it gets even more interesting as there is a common mode somewhere.

Focus first on these VM connection items ...

Yeah they turned up and cut down the lawn etc. Quite the shock as I wasn't given a date and then saw two guys in the garden!

[manytentacles]

Looks like we're in the same area. Well a couple of us are. thanks for the heads-up.

[Sephiroth]

These ones are difficult to fix because difficult to pinpoint the noise or whatever is affecting your upstream.  For example, a VM business user on an industrial estate nearby with electrically noisy equipment.  Takes some pinning down.

Hi manytentacles

Thank you for your first post, welcome to the Community Forums.

I'm sorry to hear you've been struggling with your connection since the start of August, I appreciate this must be getting quite frustrating now.

I appreciate you've been advised this before, however there is still an ongoing SNR outage in your area which will be affecting your speeds and connection stability. This is likely why your repull didn't seem to improve things.

The estimated fix date is showing for tomorrow at 9am. Please let us know how things are tomorrow and if you are still having issues, we can check this again for you.

Kind regards

[Sephiroth]

Just to say, that the 'estimated fix date' is artificial.  I advise you to request the ticket number and priority from the Forum Team.  If it's a 'P4' then the estimate is worthless.  Area noise should be a P1 and there is no estimable fix date until the source of noise has been determined.
