Since moving to the fusion unlimited 30\10 plan, from adsl I have been expericing significantly higher ping than I did previously on ADSL. 

While on ADSL my ping to North America game servers like league of legends would always be 163 ms but since the switch I sit at a constant 219 ms.

This is the same with local and australian connections, I would previously get 54 ping to Australia on Counter strike but since the switch I now sit at a constant 75.

When I speedtest WXC or a New Zealand server I get 44 ping which seems very high to me, since previously it was 20-23.

I am located in Palmerston North near the airport.

What do you think could be causing this significant increase in ping, it is making playing North American servers games unbearable.

https://www.speedtest.net/my-result/3761815092 this is a speed test to NZ showing 44 ping

Below is a tracert to league of legends game server.

I am very happy with the speeds, but I just don't understand why all my pings would suddenly increase by 20 locally and 60 internationally. I value the ping more than the download speeds, but I don't see why I can't have both. I would have thought UFB would actually make my ping lower!

Hello... Our robot found some keywords in your post, so here is an automated reply with some important things to note regarding broadband speeds.

 



 

If you are posting regarding DSL speeds please check that

 



 

- you have reset your modem and router

 


 

- your PC (or other PCs in your LAN) is not downloading large files when you are testing

 

- you are not being throttled by your ISP due to going over the monthly cap

 


 

- your tests are always done on an ethernet connection to the router - do not use wireless for testing

 


 

- you read this topic and follow the instructions there.

 



 

Make sure you provide information for other users to help you. If you have not already done it, please EDIT your post and add this now:

 



 

- Your ISP and plan

 


 

- Type of connection (ADSL, ADSL2, VDSL)

 


 

- Your modem DSL stats (do not worry about posting Speedtest, we need sync rate, attenuation and noise margin)

 


 

- Your general location (or street)

 


 

- If you are rural or urban

 


 

- If you know your connection is to an exchange, cabinet or conklin

 


 

- If your connection is to a ULL or wholesale service

 


 

- If you have done an isolation test as per the link above

 



 

Most of the problems with speed are likely to be related to internal wiring issues. Read this discussion to find out more about this. Your ISP is not intentionally slowing you down today (unless you are on a managed plan). Also if this is the school holidays it's likely you will notice slower than usual speed due to more users online.

 



 

A master splitter is required for VDSL2 and in most cases will improve speeds on DSL connections. Regular disconnections can be a monitored alarm or a set top box trying to connect. If there's an alarm connected to your line even if you don't have an alarm contract it may still try to connect so it's worth checking.

 



 

I recommend you read these two blog posts:

 



 

- Is your premises phone wiring impacting your broadband performance? (very technical)

 


 

- Are you receiving a substandard ULL ADSL2+ connection from your ISP?




I am the Geekzone Robot and I am here to help. I am from the Internet. I do not interact. Do not expect other replies from me.

According to that traceroute, you're still going to an XDSL gateway instead of the ffth one.
Would try a factory reset on your MP264 then let it re-provision on UFB and see if you are going to a ftth gateway instead.
Also if you want, pm me your username and i'll make sure there's nothing wrong on this side.

Regards,
Andrei.

I made a mistake in my original post, we were upgraded from ADSL to VDSL, not to UFB which I thought was available in my area.
I tried a factory reset and fiddling with the router settings but nothing decreased the latency.
I think it might be to do with DLM but I don't know how to check which one you are on or change.

It may be due to high interleaving, which will be where DLM starts out.  It should reduce this if your line is good enough to cope with less interleaving.

If you had it switched off completely before, then even after DLM training is complete your first-hop latency is still likely to be a little higher on VDSL than it was on ADSL.

adsl can have interleaving turned all the way off, unlike VDSL which is controlled by DLM.

For gaming, DLM can actually work out worse off than running on ADSL.

however assuming you have a master filter installed, a decent modem (which while i have not played with it myself, the WXC modem seems pretty solid) you should be able to keep DLM-1.


Dont reboot your modem if you can help it, the DLM process can consider this to indicate an unstable line and look at moving profiles.



its a little hard to work out your latency value for DLM off your traceroute as your a fair distance from the POP it seems. Ild have a hunt around your modems UI, Otherwise ask WXC to check what DLM profile your on?


Here is what the DLM profiles translate to..

DLM-1     1ms  0INP

DLM-2     8ms  0INP
DLM-4     8ms  1INP
DLM-6     8ms  2INP

DLM-3   16ms  0INP
DLM-5   16ms  1INP
DLM-7   16ms  2INP
DLM-8   16ms  4INP

Unfortunately the DLM profile is not something we can set to a certain profile. It will automatically adjust to whatever it is most suitable for your line quality.

I have had the same issue when I changed to VDSL, my DLM profile automatically set itself to the one with highest interleaving because my line would drop off every time it rained. There was nothing I could do about it. I was playing dota2 with 80+ ms latency on Aus servers.

PS. you are currently on this profile  VDSL2-DLM-5  , I will organize with Chorus to reset it to default, then you will need to not restart your modem for a while. It may set itself to a different profile, or end up on the same one.


PPS. It is done, reply from Chorus :
"DLM has been reset as per your request, customer may see occasional re-syncs while profiles are automatically adjusted over the next week."

Thank you for the help. 

 

The modem was probably rebooted once a week or so, which probably caused the DLM change.

 

Hopefully it will resync to a lower one since every little bit of ping helps, but no changes yet.

once a week is very minor.


a common statistic i normally refer to, is it takes on average 2~3 reboots on DLM-1 to loose it.


to double check, there was a master filter installed as part of your upgrade to vdsl? (im not sure if WXC do full installations, but i assume they do.)

Yes we do have a master filter installed.

great.

not sure how you managed to get to DLM-5 in that case however...

hopefully you can hold down DLM-1. that 1ms each way, is very easy to get along with.

It has been more than 10 or so days since the DLM reset and pings are still exactly the same. The router did not die or get reset over this period. I did not notice any re-syncing or anything that was meant to happen. 
Is this connection just destine to be stuck on DLM - 5 ? Or is there something else I can do.
Also, do you know when UFB will be coming to my area(4414 Milson, Palmerston North) with WXC, as other companies already offer it to my residence. I really want my old pings back, its almost verging on unplayable, I've had to get a ping lowering service to lower my ping to North American servers which helped, but it still years away from the adsl ping I was use to.

You're not going to get your "old" ping back. Simple as that.

VDSL2 dynamically configures your line profile to give you the most stable offering, and this will mean interleaving can increase to do this.

If latency is so important then ADSL2+ with interleaving off is your best option.

This.

Although there are some things you can do..


I am no familiar with the WXC modem, so i cant tell you where to find it, but ild suggest looking to see what sort of CRC error rates your getting. - if you cant do this, hopefully the CSRs will be able to run a test or two, and check if your possibly getting heavy errors causing your profile to go back.

the only lines i have seen sit on DLM-5 or greater, did have errors of some sort on them, and unfortunately can be a pain to get right.


If errors are not the case, Disconnections are not the case, Ild have to say, your simply rather unlucky. A Sizeable amount of VDSL users sit on the 1ms or 8ms profiles, the occasional 16ms does crop up though.
