After dDLM my sync rates eventually settled at 70/17 and stayed there. Then last week I checked my rates and saw...

Cool!

 

Then yesterday a Chorus guy came to fix a fault with one of my neighbours, and for some reason needed to dig around in the termination box outside my house. No change yesterday, but this morning:

Officially maxed out!

 

Finally, reposting my original pre-dDLM line stats from earlier in the thread for a direct comparison:

All I can complain about is my interleaving, which got heftier with every speed bump. However I hardly play games anymore so this is more than a worthwhile trade. Well done Chorus - for those of us left waiting another two years for UFB this is a meaningful improvement to my quality of life!

So turns out they had a bit more digging around to do before they packed up and left. And now I've got:

From 70/25 before they came on to my property, to 67/5 after they left.

 

What can I do here? I lodged a ticket with Bigpipe, who replied saying 5mbps was acceptable and Chorus would reject a request to come back and fix it.

 

The unexpected speed boosts are the fun part of VDSL, but this really sucks. Your speed can drop to 1/6th of it was overnight and it's apparently completely acceptable.

Copper technology is inherently much more variable than Fibre technology. Yes. Chorus could well argue that it is is within "operating parameters". A sympathetic RSP may push your case on your behalf but you may be hit with a hefty No Fault Found Fees.

 

In September this year, my VDSL download speed drops from mid 50 to 27. Logged a case with Spark and they can see my historical speed was in the 50 and accepted that that was likely to be a fault somewhere. So I guess it depends on whether your RSP looks at the historical record and how severe the drop is.

Looks like mine isn't budging anymore after sitting on 60/30 for quite a while but then dropping to 49/16......

My upload speed has been 17mbps since dDLM came in in April and my line switched to 17a. It boosted again to 25mbps a few weeks ago after my SNR improved, and then to 30mbps last week after another improvement. That's at the least a 2/3 drop, which seems pretty severe to me.

 

Unfortunately from Bigpipe's response to my ticket, it seems like download speeds are treated more seriously than upload, and I haven't had a big drop in that. As it happens upload speeds are much more important to me.

 

Isn't 67/5 a weird/lopsided enough sync that it would ring some alarm bells? As would the fact that it happened after Chorus came and dug around in my termination box (and there are now wires sticking out of it that weren't there before)?

 

This sucks :(

67/5 is definitely weird. I am currently on 62/20 for nearly a month now with the good weather. I wonder a sympathetic RSP helpdesk personnel might champion your cause. Suspect it has something to do with Chorus digging around the neighborhood as you have said and affected your line.

I'd log that one if you contacted me as an agent.

Disclosure would be highly likely. But end of the day that's a large drop. Your margins are still low.

One thing i would caution is please triple check isolation tests first. Upstream is typically internal.

Thanks hio. I'll replug everything and clean the contacts on the cable to be sure. I only have a single connected jackpoint so there's not a lot of other testing I can do. If that doesn't change anything I will try begging the Bigpipe CSR to send it through to Chorus.

 

The upstream is running at 10 SNR so there's room for it to improve a bit as DLM reoptimises the line, but there's clearly been a significant decrease in absolute line quality. If the downstream hadn't been maxed out (attainable was 84-87 mbit) I'm sure it would have seen a similar drop to the upstream.

Crowdsourcing time, i need a few test cases.

 

 

 

hopefully before about 6pm today... Looking for Spark connections which have had what you suspect to be ddDLM changes (eg snr adjustments) over the last month period.

 

Trying to run through some statistical analysis that doesn't have the messy line fault situations in it - Easier to look here than deep dives!

What version Firmware you running ?
Don't think you have Vectoring supported Firmware
It should say this under firmware version 
'VDSL Firmware Version : 05-07-06-0D-01-07 [with Vectoring support]'
This is from latest FW 3.8.1.2 modem 4

 

When vectoring comes in (supposedly shortly) you'll be all set to take advantage

Thanks! So modem4 is the version to use? I currently have 3.8.1.2 but probably STD I think.

STD FW doesn't show any details of your connection and also doesn't support vectoring
In your status now there are more details of your connection, did find it odd that you had no Attenuation 
MDM4 is for NZ, others work too, but 4 seems to work best.

Anyone from slingshot that can take a look at my line? I have noticed my speeds getting gradually worse and my error getting higher, after about 2 months of being stable at around 70mbps downstream the last couple of weeks my line has been getting more and more CRC errors.

Here are modem stats from 2 days ago


Here are my stats from today
