Just moved to BigPipe although they said move is gonna happen tomorrow, sync speed dropped to 48Mbps from around 68-69Mbps. Is this normal? What exactly happens when you move? I thought it was only change in billing. What does chorus actually do in the move process? Hope I will get my speed back. Speedtest.net showed around 64-65Mbps before now only 7-8Mbps. Something really wrong!!!

If it is vdsl it is very close to the theoretical maximum.

if your sync speed is 48 then there is nothing wrong, its just not as good as what it was, and potentially to do with DLM and the move to the new provider

what speed do you get when you download a file or for example a torrent? 4k youtube video etc?

Well yes it is VDSL I get lower speeds than before. Downloads in torrent were like up to 3.8 to 4 MBps before now only 1.4 But why did the speeds drop?

its the fickle nature of VDSL

if sync on your modem is still 48 then its not the conenction

Can you post your connection stats

Does "DLM training" happen again if you change ISP? It might get better over the next two weeks (don't restart your modem).

2 things going on here

1) Sync speed change. This is possible when switching providers on VDSL since it resets and restarts the DLM process. it may change over the next 2 weeks, or it may not. It is something only Chorus control and has nothing to do with your choice of ISP.

2) Poor speedtest results (worse than expected on new sync speed). This could be a large number of things. Since PeterReader seems to be absent (probably out having a few beers on a Friday night) I'll re-post his questions. If you can answer those we'll have more info to be able to help diagnose the problem.
In my experience the two most common cause of slower than expected speedtest results are
a) testing over congested wifi
b) testing whilst other stuff is happening (e.g. flatmates torrenting, PC performing automatic patch downloads etc)

It would also be good to email our team and they can take a look at your line to see if anything looks odd. I'll add in the stuff we already know
https://www.bigpipe.co.nz/#/support

From PeterReader:

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 BIGPIPE VDSL
- Type of connection (ADSL, ADSL2, VDSL) 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 URBAN
- If you know your connection is to an exchange, cabinet or conklin
- If your connection is to a ULL or wholesale service WHOLESALE
- If you have done an isolation test as per the link above

Looks like a classic case of 17a dropping off with the profile resetting.

Give it time, you will most likely get your 17a profile back at some point.

can't play 4K videos at all. Can anyone confirm if 4K videos are playing fine for them and maybe post which one so I can test. Thanks

I already did. you really need to give more information before we can help at all

e.g.

Have you checked you (or anybody else) isn't saturating your connection with things like torrents, software updates etc.

Are you using the exact same setup as you had before? e.g. same modem/router, same jackpoint in the house etc

Have you emailed our support team yet about it? They are the only ones who can look directly at your line to see what's going on.

I've checked my own connection - similar sync to yours (45Mbps VDSL) and have no issues at all with speedtest or watching videos etc (including the video linked to above).

Looking at our network traffic there is nothing unusual there either - plenty of bandwidth at our end.

The problem is (probably) either going to be in your setup, or somehow in the cabinet exchange if something has been done unusual there (but a VDSL transition shouldn't require a cabinet visit, the switchover should be done remotely)
