Wow, @Gordy7 got such rapid help with his problem https://www.geekzone.co.nz/forums.asp?forumid=49&topicid=251066, I logged a fault with Voyager 24hrs ago and haven’t even had an acknowledgement yet. Maybe I will have the same luck as Gordy7 with geekzone. Here’s my story.

 

Yesterday at midday my ADSL connection was switched from Spark to Voyager. The only downtime was the couple of minutes it took after my connection to Spark dropped until I had entered Voyagers settings into my router. Perfect, I thought, until I did a speedtest which showed ~40% drop in download speed from 13.44 to 7.79Mbps. Logged the fault with them and started troubleshooting.

 

So, to save a lot of questions, my connection is via ethernet, structured cabling in a near new build, naked broadband with no filter. Have done a factory reset on my TP-Link TD-W9980 router and double checked all of Voyagers settings – the only problem is there is nowhere (that I can find) to enter their MSS setting. I have also done a speedtest with my spare TP-Link TD-W8960N router – no difference. I have disconnected all other computers, server, NAS, AP, phones and printer from the network – no difference. I have done speedtests to Voyager, Spark and Vocus servers – no difference.

 

Was I naïve in thinking that I should get the same speed from Voyager as I did from Spark? It never occurred to me to ask Voyager about this when I signed up, particulary as their advertising makes much of their “obsession with speed”, “fast & reliable internet” and “our speed supersonic”. I would have thought that a mere mention of speed problems they would have been all over it. Not so.

 

Any suggestions folks? Do you think Voyager can work some magic on this or is there something in their system that is inferior to Spark. Happy to persevere with this if you think it will have a happy ending, or should I just switch back to Spark? I should also mention that the Chorus broadband checker says that our speed should be ~13Mbps.

 

Thanks in advance.

Port will have reset. Your now on 12dB SNR. Wait for dd-DLM to adjust it again.

Yeh the worst thing you can do is keep disconnecting/reconnecting it.

 

I would just wait a while.

And that can take up to two weeks to come right again.

3 months for me when vectoring was enabled...... it was a sad time.

Yes... wait for your new Voyager ADSL connection to tune up.

 

The guys here on geekzone are always very helpful.

 

Voyager especially fill in the technical gaps in my understanding... as per my fibre speed test issues I had yesterday.

So, 2 weeks on so I thought i would give an update.

 

2 days after the switch over the SNR on the upload went down to 6.4 and upload speed went up from 0.65 to 0.83. Since then the best speed that I have measured is 0.86, still less than Spark's 0.92

 

The download SNR has stayed in a range of 11.7 to 12.2 with ,understandably, no improvement in download speed. But I still live in hope.

 

Interestingly, right from the get-go much better ping from Voyager - consistently 7 to 8 ms whereas I only ever got double-digits from Spark, usually around 19ms.

 

Quick question - is it necessary to do a port reset when changing providers? In another thread I see reference to a "destructive port rest". Is it possible to perform a "not so destructive" port reset?

 

For the record, still no contact from Voyager support.

You had a different interleaving profile on spark compared to voyager.

Based on your error rates it's possible that dlm isn't willing to risk dropping your downstream snr.

Adding interleaving is one way of sometimes adding a better QoE even if latency increaseing seems negative.


Bit errors with interleaving off can hammer tcp performance.


Sorry @bmarquis feeling too lazy this morning to over analyse your network further ;P

I don't think Yoyager can actually add any value to this thread

The other thing is I know Spark worked quite hard on optimising the downstream policer so that traffic never gets dropped by Chorus at the DSLAM or by the access network. I know since I worked on it.

So while the speed may be slightly slower the overall experience just "feels" better.

Thanks again @BarTender and @hio77.  So, from your comments above, am I correct in concluding that my speed may never improve with Voyager? If I switch back to Spark I would expect similar speeds to what I had before? Please understand that I am not being pedantic here. A 40% reduction is significant and we now experience quite a lot of buffering and jittery playback when streaming video.

 

I noticed this morning that the Chorus broadband checker says that we "might" be able to get VDSL here. I am aware that we are  right on the edge of VDSL coverage, but I am guessing that you would say "don't go there" considering the errors that I am getting?

You might have better luck asking voyager to switch you to low interleaving....

The issue is that for some reason you had an artificially high sync rate on Spark - the 1.4dB noise margin on the old downstream connection is the giveaway.

 

This will have happened because your modem happened to sync when there was a very low background noise (immediately after a power is the most common). The lowest Chorus set id 6dB, not 1.4. Because of this, you were seeing a much higher sync rate with Spark than you should reasonably expect to have had. With a clean line, the noise margin may drop as low as 6dB and your sync rate will increase, but you are never going to see the same sync rate you previously had (no matter what ISP you are with), unless whatever lucky sequence of events that caused your modem to sync higher than it should have happens to magically occur again.

 

Having said all that, both your before and after shots are showing downstream errors on the line. This is usually the result of poor internal physical wiring, and probably something that can be improved. If you do this, you may well improve up and downstream sync rates.
